Which ECU do you want if it's available for US GT-R

[ATLsupra]

We have seen several companies modified their ECU now. The question is which one do you want, and why?;)
Companies has modified ECUs and informations:

Mines (confirmed) - The Mines VX-ROM ECU modified the following: Remove GPS-driven speed limiter Modified fly-by-wire throttle mapping Modified fuel map Modified ignition timing mapPrice: 126,000 yen (approx $1210 USD)

Amuse (confirmed) - HiTech Rom Remove speed limitRaise turbo boost (1.2BAR)Remove speed limiterPrice: 158,000 yen (approx $1520 USD)

Endless-R (confirmed) - Current using RH9 ECU, their racing version (more boost) is still under development. No boost increase Speed Limiter disabledsatellite record of 309kmh
Price: 145522 yen (approx $1400 USD)

Esprit (confirmed)
modified boostchanged the fuel mappingPrice: 138,600 yen(approx $1350 USD)

COBB (confirmed)- Using AccessPORT which is not a piggyback, it reflashes the ECU and if you unplug it from the OBD-II port, to rewrite the map any way you want.
HKS (not announced yet) - only piggy back available now
HalTech (confirmed) - in development
Speed For Sale (will we have one? :D )

Ummm, that is a tough choice and they would all offer just abou tthe same stuff. Bottom line comes to cost and what brand you like.

as for me I may go with none. Why? since Cobb Tunning is making the accessPORT for th eGTR that may do just fine up to 550-575HP...I'll have to wait and see...My goal so far is no more than 550HP...but i am man, and man is greedy...lol;)

[fled]

Mines. Why? I have long respected their tuning philosophy which is centered on overall balance within the vehicles capabilities and response as opposed to a WHP figure. They are pricey, but I believe you get what you paid for with Mines.

[Ev0H8t3r]

I may want to try something different, in the past with all my cars it has always been tunned and mod by JDM and Japanese makers, I may want to go all out and go all US makers on this USDM GTR ;) time to bring the bacon home lol

[ATLsupra]

updated with ECU information. Looks like COBB's AccessPORT is pretty interesting.

[BennyBlanco]

probably Cobb
they are in my hometown

Yes ATLsupra, I second that. Can't wait to see it in some ones GTR!

One thing to remember, if S4S does offer one, Jeremy's tuning mind is peak performance with reliability. When we build a car at S4S it is for a 100,000miles or more, not a peak number car. We also try to develop cars/parts that are emissions friendly. Check on the site about our stock turbo upgrade option, it is on Frederick F.'s car.

I like what I hear! S4S philosophy is the same as some of the best Tuners in Japan.

I am glad to hear that! I can’t wait to see you products for the GT-R. Like I stated before, I want to try and go all US tuner/maker products on my GT-R.

This will be a new concept for me, and looking forward to it. Last car was a mix of US and Japanese Tuners parts, all cars prior 100% Japanese parts.

COBB is the front runner at the moment for USM GT-Rs. Personally, I like their programmable approach. I have a laptop dedicated just for data logging and programming.

Haltech may also be a player. They did an awesome ECM for the 350Z. It will probably be a year or more before Haltech has a replacement USM ECM. They spend a lot of time in development. The Haltech ECM will also be programmable.

None of the current crop of JDM tuners have an ECM specifically for a USM GT-R; although, Mines says they'll have one this summer/fall. I would be very careful putting a JDM ECM on a USM GT-R since the USM GT-R has a slightly different ECM program.

[AdamSupra]

I am going to say Mines, only because I know that theres will be awesome as always once they crack it all and go crazy.

[tomgtr]

Erm, think 480 BHP will do fine for me. The verry rare occasion that one would need more is not worth the risk for me to wreck it. Erm, well I said the same about my STI a loong time ago, and that didnt hold up to long.

I will be the first to reach 1500 hp on my light force bucket.....

Piasini Engineering is also in development of a "Flash" tune

Piasini Engineering is also in development of a "Flash" tune

Where are they located and what is their history. thanks

[Nypest]

Where are they located and what is their history. thanks

Piasini is located in Italy. "piasiniengineering.it" is there home page they have tuning capabilities for MANY ECU's..... I currently have there device to tune the 2.3turbo Mazdaspeed... I was speaking with Christian over there and he tells me they are working on this ECU currently... Just a little info for you guys incase you want to research it out :)

Modify the Factory ECM, or any add on that modifies the factory settings will result in any engine repairs being VOID in a warranty claim. If you have an extra $27,000 to buy a new engine (part only) go right ahead. If the modified engine causes trans problems, it will cost you $18,000 for a new trans.
Anything...even an aftermarket air filter, will deny any warranty claim.
If this is pocket change to you, have fun!

[JaredPink]

Nissan can not do that. It is against the law. The only way Nissan can say a warranty is void is if the after market air filter came apart, and was ingested into the engine. They are coming out strong saying just about anything will void the warranty, but legally, they can not.

We will see how long that last. Ther always a way to put it back to stock and do a Warranty claim. Ask the EVO boys?

[elpasocrna]

one of the other guys pointed out that cobb will have a lot of experience on the american make gtr and mines, amuse will have more experience on the JDM. There are possibally 3 different ecu's and a different ecu in the us than Japan. So cobb may be the way to go.

[Romper]

Since ATLsupra started this threasd in April, has Comb put out any more info on their ECU... e.g. price or Dyno results?

[elpasocrna]

Lets try a re vote when Cobb comes out with the accessport. will be available by end of AUGUST.

[Romper]

I'll be looking forward to the end of AUGUST... :)

[mindlessoath]

Cobb accessport has so much more to offer and a great price too boot. its the best deal and the best performance. i dont see why anyone else would buy mines ecu. its not that great. its just first out the door and plays it safe. to me cobb does it even better.

[Ev0H8t3r]

COBB ALL FTW! I hope JB and S4S team can make somthing like it as well...

[topspeedinc]

Cobb AP.. might as well goto the source.

Cobb's programers and calibrators flew over to Mines a few times this year to help Mines develope their ecu flash. As far as I know Mines has the sole rights to all JDM ecu's but has to share the USA and Europe with Cobb.

Nice thing about Cobb is that the AccessPort will come with multiple maps that allow the end user to switch between. Eventually down the road Cobb will also allow for certain protuner shops the ability to do one off custom programing via Cobb's Protuner software.

Thats hard to say because COBB tuning is using a JDM GTR. They imported it earlier in the year. I know they were trying to get ahold of fellow US GTR owners so they could download the ECU, which im sure they have done by now. Either way I would have to go with COBB. If I want help or have any questions or want it specifically for my car, I can call someone that speaks english :)

[mindlessoath]

ok a few things here. Trey COBB just confirmed that they did not go over to mines to help them. they are direct competitors. They dont share nothing with cobb. the rest of your statement is correct tho.

Cobb tuning has already been beta testing on the US market GT-R's. sofar nissan has 3 differnt ecu's and cobb has taken care of each one to be compaitible. sofar the cobb tuning accessport is just released and doing great! cobb are running about 580 something horse power, added engine oil cooler due to overheating issues and have huge plans for more.

mines has many distributers in the usa and alot of them speak english, so dont worry about that at all. mines is not a bad compainy, they are great, but they leave me wanting more especialy after cobb access port has so many great advantages.
here is a recent post i made about the cobb r35 http://cba-r35.blogspot.com/2008/08/up-close-with-cobb-tuning.html

here is the Access port release leter from gtc-r.com http://cba-r35.blogspot.com/2008/08/gt-r-r35-accessport-release-available.html

a general search of COBB from my blog http://cba-r35.blogspot.com/search?q=cobb i have posted up Q&A posts, pics, vids etc.

[stuhagen]

This is the most recent thread all about the Cobb unit. Pretty much all questions about it are answered. You can go to the Cobb Forum as well.

http://www.nagtroc.org/forums/index.php?showtopic=24116&st=0

They make mention of GT-RR as a place to buy it, and they have already shipped out several. http://gt-rr.com/gt-r/r35/cobb_tuning/part/accessport_-_engine_tuning_solution/pid/158

I am sure Jeremy can supply this as well. This unit looks promising!

[Romper]

Thanks for the update. I'm curious to hear from someone that actually has over a 1000 miles on the car and has installed the COBB AccessPort. Can you really notice the difference when you stepped on the trottle? Or does it help when the car is in higher rpms and building up speed to its top speeds? I'm even more curious how much it effects the boost settings?

This is the recent thread that brought it to my attention. He just dyno'd and next week he does his CobbAccess port tune....have to keep an eye on it.

Stu

[mindlessoath]

the cobb stage one is very simular to the mines ecu in the fact that the boost is simular upgrade. other than that the map is tuned differntly - the accessPort giving a better afr and a really nice power band tuned for this engine. but something that the accessport has is multiple maps. say you do aftermarket exaust you can upgrade to stage two allowing alot more boost and an even more improved power band.

the mines ecu is more expensive and doesnt offer nearly as much as the Cobb unit. So they differ significantly. in tunes. granted the stage1 is sort of simular, its really all the R35 can handle without upgrades, so its neither compaines fault.

[Norman]

Amuse,it take the Japan festest GTR on the track!1,2 goes to 611hp!

[mindlessoath]

ya thats with down pipes whole exaust setup etc and aero mods and a custom tune ecu.

[DarinF]

AP is too easy.. flashed stage 1, 91 octane yesterday and love it. Cant wait for stage 2. Going to dyno tonight so will post what I find.

Nice please keep us posted on your results.

[Rodrigo]

Mine's has the name and the fame. However, COBB gets my vote due to it not being a piggyback, having the ability to reflash the ECU, and give us the freedom to do what we want with the GT-R. Freedom is good.

[Norman]

Seems i need to try COBB too^^,i heard that AMUSE even change the throater map to refine the pedal "feel", that's the point i vote AMUSE before.ever heard other brand had this function.
But COBB's ECU reflash also attractive to me..^^

[V8_Club]

Mine's , seems like the one with most features for your $

[Norman]

what "special" features Mine's got?:confused: i though it was most basic one...

[V8_Club]

Mines (confirmed) - The Mines VX-ROM ECU modified the following:
Remove GPS-driven speed limiter
Modified fly-by-wire throttle mapping
Modified fuel map
Modified ignition timing map

The COBB is the other one I would consider. The others just raise boost or remove speed limiter.

[zcargtr83]

I have cobb stage 2 and I LOVE it. VERY large difference between stock and this. I installed my air filter, mid pipe and catback first... ran it for 1000 miles and then installed the accessport stage 2. BIG difference in throttle response at low rpms. A bit of an overboost isse, but the latest update dealt with that. I will have dyno numbers soon! And once my down pipes come in we will be doing a custom catless tune. Anyone on the fence I would say go CObb for a couple of reasons:
1. They are in the US and they are actually availble for support. You cna call them with your issues and they will help you out.
2. They are conatnatly updating maps andadding new ones. Their system also allows for a custom dyno tune at approved tuners!
3. The accessport can also read fault and trouble codes and tell you what the issues are which the other tuners can not!
4. It has a datalog fuction that is very useful if you do have an issue or if you want the street tune the car.

What power level would you say you are at ? How is the tranny holding up ?

[zcargtr83]

somewhere between 550-575 whp. Once the downpipes are nstalled we will be going custom tune and then we shold be floating near 575-600 whp

[V8_Club]

Transmission ? Anything done to it to hold that power ?

[Norman]

i think transmission run 600whp still in safety margin

[zcargtr83]

there are not any solutions availableyet thatI am confidnt enough to invest in. This is notsomethign you want to be the first to try in my opinion.

[mindlessoath]

the trans can handle a max of 90kgm of torque. running approxamatly 80% of that will have the clutchs start to slip a little, more so when running more of that.

sofar i have seen the accessport bring about 80hp maybe slightly more to the R35. the gtr570kit gets 110 to 150hp (give or take).

[V8_Club]

So is the COBB Tuner within the safe limits ?

[mindlessoath]

the cobb stage1 is within perfectly safe limits. stage2 is alot of power but no where near the limit. i would say its pritty safe, but no one knows for sure how long that will last on the car if used heavily since it hasnt been to long yet.

the gt570kit is at the highest safe limit. they have two stages, the secound stage is 20hp more (17psi) and others are trying 19psi even tho HKS recomends not to for a few serious reasons (i can look it up if you want me too).

but cobb is well within a safe range right now.

i recomend everyone running higher horse power to run a better gear oil in the trans. tho there is only one that has released, and its not in the usa... you can order it from OZ.
http://www.dwtuning.com.au/forum/viewtopic.php?f=13&t=33&p=130#p130
its cheaper and better than the factory trans oil.

[zcargtr83]

For the first time ever mindless and I do not agree on something ... the cobb stage 2 is somewhat adaptive and when used with a boost controler along with full catless exhaust, aftermarket intake, and a few other weaks you can see just as much power as the hks power program. The hks system is basically just a boost controller, a pair of bypass/blow off vales, catless mid pipe and turbo outlets when it comes to power... yes you get iridium plugs and a hard pipe kit... but other then the actuators most of the kit outsde of the exhaust and increased boost is really not all that helpful in increasng power. HKS went for supporting modification more than power mods. The blow off valves and hard pipe kits are not good for any more power but do hel the system to stand the extra power. I would be VERY VERYsurprised if a minor modification of the stage 2 map did not et you to 550-570 whp with intake and full exhaust. 17 pounds of boost is going to make relatively the same amount of power no matter what minor mods are added

[mindlessoath]

well, that goes without saying about the cobb unit. but out of the box, its not (take off shelf and install). cobb is working hard on making the same power or more and trying to reach that power without all the bells and wistles of the GT570kit. yes you could spend just as much to get the same or simular power.

i dont dissagree with you there. its somewhat adaptive.

the cobb unit is better because it doesnt need a boost controler (cobb says one shouldnt be used, but others have seen it works fine for them) but its better or more accurate to adjust boost in the ecu the way cobb does, than using a boost controler which is not always safe, especially at higher psi.

but your right, 17lbs of boost no matter how you get there is going to be alot!

other note: the reason why hks says not to go above 19psi is because of the injectors, they are not big enough to go higher.

There are so many sides to it. im not going to argue about it tho :P please feel free to dissagree, cause i agree with your points too.

[zcargtr83]

lol just wanted to disagree since you are right 99% of the time, but it looks like we agree anyways. I somewhat misunderstood what you were trying to say. I just thought you were saying that the hks kit was capable of more power. Though we are seeing more people using accessports with the hks systems and ditching the boost controller. I just think it is much easier to get yourself into trouble with a boost controller set up liek the hks system because it allows you to overdo the boost and the rest of the system can not adapt.

Good info as always mindless! Your input on here is extremely vaulable.

[mindlessoath]

thank you. i appreciate it. but if it were not for the community as a whole, i wouldnt have any data :P

my wife could kill me sometimes tho.
