4G63 ECU

[Caine]

Ok I need to know how to modify or what to replace this with so that my car has higher limits. Thanks

[M 4 L k i 3 R]

TMO has stopped doing ECU upgrades, but I found another company that does it the other night... http://www.ongreenperformance.com/

I tried emailing them about thier product, but being a long holiday weekend I dont expect to hear from them until tues or wed.

Or you could just go ECU-less with an AEM standalone :thumb

[OWNDJOO]

stay away from AEM!! get haltech e6k or a MOTEC

[Gunner]

Fuck all of the above. Get a FAST system, www.fuelairspark.com

[Mike C]

stay away from AEM!! get haltech e6k or a MOTEC

What's wrong with the AEM? Buschur, RRE, and Shepherd are currently running them :confused

[Iwishiwascool]

Buschur, RRE, and Shepherd are currently running them

oooh, rich's own line used agains him. Pow.

[Gunner]

Yes, but Buschur, RRE, and Shep get first hand support when they have issues. The distant user has no such luck when the ecu decides to melt down. There have been tons and tons of problems with them. IMHO it's the rice boy's standalone EFI system.


FAST< FAST< FAST< FAST< FAST

It's a long proven system that has a rep for being very user friendly, and offers as much control over engine perameters as any other system out there. Hey, it's what the fastest Mustang guys use!!!

I disagree to an extent. These are the pros and cons of saving a little money or dealing with a real dealer. Lets say if you buy the AEM system from Buschur and have a problem with something, you are going to get support and the problem fixed because you bought it from a respected dealer who knows what they're talking about vs paying $100 less and buying it from some guy in California. I'm not saying that the Haltech or another system is bad, just that I would rather buy a system that I knew I could get real support from. I think that when you get that far down the mod list of needing a standalone, which should mean you are running sub 11.00, that you should be able to get all the support you need from a company and the dealer you get it from. I just have a hardtime beliving people like RRE and Buschur would support a product that is "ricer". I don't think that "ricer" DSM people aren't buying AEM Standalones like Honda guys.

[suicidalsquirrel]

yea, if I had my own personal dyno, I would use an AEM. After seeing all the points of Adam Moore's AEM, I wouldn't have the first clue what to change, and how to change so much at once. If I had a crew dedicated (and paid) to tune my car like Buschur does, I would use it. *note to self......buy a dyno for B&H racing*

[ucsigep]

I would agree with Gunner on this one. The FAST system is pretty sweet. Very well known, I even had a guy I work with (5.0 Mustang owner) who was talking about how if he was going to go fuel injection, that's the system to go with. Granted, v8's and i-4's are different, but I was checking out their website and think for my money, that's the way I'd go.

[Mike C]

I'll definately start doing more research into the Fast system. I've got big plans for this winter. I'm just not going to be the pioneer or guinea pig for something completely new to the DSM community that's all. I agree the AEM is stupidly complicated and probably the others are as well. I just want to make sure that I have top notch support on whatever I run so I don't toast my pretty new motor :D Like I said before, I don't think the average fast 12 second(me) DSM should be running a standalone. I plan on starting next year with my VPC/GCC and seeing how far I can get with it.

[Gunner]

There is a TON of tech support for the FAST system. Buick GN, and 'Stang guys have been using this as the staple of their tuning tools for a long time now. There's the fact that I like to be different too, and I don't like to depend on a "shop" to help me out with every baby step. From what I hear the FAST system is very user friendly, and if you do have problems, their tech support is fantastic. Definitely good bang for the buck, and it seems to be the system of choice especially in high powered boosted apps.

I will have to throw another vote in for the FAST system. So far it is the easiest and most powerful system I have tuned with. Works very well with a blown or nitrous car. I ran an NA setup on my old Mustang with the FAST system and picked up 68 RWHP on the dyno. Now with my 88 Mustang I'm going to try and just interface the stock ECM.

I wish I could find something like this for my GST...

dsmlink for all your tuning needs :) Not nearly as costly as an AEM.. nor as difficult

Well I'm assuming that since we're talking about it, then there is a version for our cars? Am I right or is this something only available for domestics?

Yes...FAST can be used for any fuel injected application.

I was stating that I wish I could interface the stock ECM other than buying a standalone like the FAST.

Ok I need to know how to modify or what to replace this with so that my car has higher limits. Thanks

I thought his originally question was about the speed limiter which is supposedly not on the 2G AWD ECU's but exists on the 2G FWD.

Or is he talking about fuel cut problems????

Ghostgsx887's question is kind of ambiguous and he completely fails to tell us what kind of car he has. GSX in your ID could mean 1st Gen or 2nd Gen. I wish he would explain in better detail what he is asking for and tell us what kind of car he has and what he has done to it already.

[ucsigep]

speed limiter, you are correct. But if he's talking rev limiter, then all of this would be relevent.

[Mike C]

Yeah I was guessing he meant rev limiter.

[BlackEclipse]

I wouldn't want to raise the rev limiter. High rpms are bad on trannies. Trannies cost $$$$$$ unless you have a sponsor.

I'd like to lower my rev limit.

[ucsigep]

fine, lower it and lose more power. Power is in the higher rpm band, especially with bigger turbos. High RPMs aren't going to break your tranny. Unless you're up there all the freaking time...

[Caine]

Ok asorry about that. I have a 1998 Mitsubishi Eclipse GSX. That makes it 2nd gen. I just bought this and the only thing i have done to it is put a strut bar on it and im sure the person before me didn't do anything. I was sent it by a friend telling me to ask you guys what to do about my car what to tune and what works best. So actually if you guys could tell me what to do to my car to make it run faster that would be sweet. And mine is AWD. I dont know what to get you guys are sending me to these sites and im looking at these things not knowing what i should get.

[EvolvedDSM]

What is your goal with the car? Looks? Straight line acceleration? Handling? All of the above?

What's your budget? Hundreds? Thousands? Unlimited?

[Mike C]

Is there a way to raise the factory rev limiter on the factory ECU without the aid of a standalone. Maybe there's a resistor or something that can be switched? For those people with built trannys I mean of course :D

[M 4 L k i 3 R]

They only other way is to have your EPROM ECU changed by another EPROM. Read here....

www.tmo.com

They don't do it anymore, but they do still have all the info up.

Nope :) DSMlink owns you Mike come on now!! http://www.dsmlink.com/images/rpms.gif

[Mike C]

Nice one Lipps :D I knew that was coming. Believe me if I didn't have $1300 invested in the VPC/GCC, then I'd be doing it along with ya.

[M 4 L k i 3 R]

Ahh...forgot about dsmlink, but man is it expensive and, if I'm reading the site correctly it has to be a 2G. $650

What's up with the Trick Flow Chromemoly Pushrod Sets :huh

[Mike C]

Ahh...forgot about dsmlink, but man is it expensive and, if I'm reading the site correctly it has to be a 2G. $650

I'd hardly call DSMlink expensive for everything it does on a 2g. Factor in boost controller/AFC/Ignition timing/2 step/datalogger ETC...

[Caine]

Why should i not get those? Is that something I cant have in my car?

[BlackEclipse]

There are not any pushrods in these motors. They are overhead cam engines.

[BlackEclipse]

Waste of money = Eclipse AEM Silver Tru Time Cam Gear (185.00)

BBK throttlebody = more waste of money. Go read on DSMtalk. Supposedly they are of poor quality and design. They break easily. Just get a 1st Gen Throttlebody like everyone else.

[Caine]

why should i get a first gen throttle body. I would think the 2nd would be better.

[ucsigep]

1g tb is bigger. 52mm vs 60mm, if I remember correctly.

[koritina]

http://www.vfaq.com/mods/1G-2G_intake.html

Left = 1g, Right = 2g

[Caine]

You guys are being really helpful thank you so much. I have heard that tru time cam gears are worth the money. Why would you say they arent? just wondering?

[biglipps66]

When you are running a massive turbo and a set of cams and need to worry about adjusting cam gears for a tooth advance and other things.. THEN you can get them :)

1g TB is better cause it flows more air...

1G tbs have taken PLENTLY of cars into the 10s and 11s

Here are some of the proven upgrade sequences to get you started with. Many of the parts you listed have never been tried on a DSM before. Even though it may be a little less exciting to follow everyone else, using the proven parts in their correct order will get you the furthest for the least amount of money.
