ecu upgrade

[talontsi26]

i was woundering if anybody knows what a g force ecu is??is it a chip ecu or is it a stand alone ecu??how much do it cost and where could i get it at??any help well be great!!!

Are you asking for a talon or for a 3S? If it's for a 3S, there are no chips for our cars.

I'm not familiar with g-force which means VERY few, if any, 3S owners use it. That being the case, there is probably a reason for it.

I don't know what it costs or where you could get it, but I could point you the in the direction of other standalone ECUs and how much they cost. But before that, why do you think you need one?


Edit: I did a search and found a few people running G-Force or Sp Engineering ECUs. Now you have to realize our ECUs aren't programmable. Which means whatever changes these companies did to the stock ECUs are hardwired onto the board. Read this I can't find exact details, some say they use a resistor or a 'daughter microprocessor', something to confuse the ECU and advance timing 5-8 degrees. Possibly they lean it out too. Honestly, this is something I would not do. It seems they charge around $800 to do this, and IMO, it's a bad idea. It's cheaper or equivalent in price to get a piggyback, such as a Greddy Emanage, where you can tune and monitor and decide where it's safe to advance timing and lean out hte fuel trims. Not just have some stupid resistor doing it the whole time. Again, I couldn't find exact specifics, but from what I read, that seems to be the case.

Also they may or maynot raise the rev limit, by swapping the crystals, but I know a member on 3si does that as a service himself. So if this was what you were after you could always send it to him. I think it's TurboBob, but I'd have to double check.

Anyway, so back to the question of, why do you want to do this?

those "laws" (if you want to call them that) could be argued so as to be enforced upon anyone who modifies their car in any way whatsoever. if you just wanna play the politician or policeman, go ahead and show us all the red tape you want; we could care less. our efforts at modifying our car are to improve their function and performance, to levels more efficient and more modern than what the manufacturer designed them for 10+ years ago. and who cares what a manufacturer does, but if they do it wrong (or the cheap way), then its a no-brainer to improve upon their design and make something better. ya, the owner/operator must assume all responsibility of the modification when he performs such task, but he does it to make something better.

so if you still want to gripe about vehicle modifications and throw out red tape, then go ahead. but the point stands that you contribute nothing whatsoever to a discussion by simply throwing out warnings of penalization, instead of offering admonitions of safety and perspective.

so thanks for being our rent-a-cop. we sure do appreciate it.

Well you can take the attitude and shove it Dude.
I was only advising the poster of the laws and rules and regulations.
What you or he do is no concern of mine.
I do not make the laws on it or try to inforce the law on it.
So lay get off of my case about it.

hey, chill. i didn't mean for an attitude to come across. i just thought whatever "laws" exist are 1) outdated, and 2) that pretty much everyone here (and anyone that modifies there cars) is already aware of the potential consequences of our actions. don't get me wrong, but you could make that same post in every thread from here until the end of the world, and yes, it would be pertinent, but i just don't think people wanna hear about it.

frankly, i'm sure 1/2 the cars on the road have some sort of modification, and could be argued they are in violation of the law. so if we're taking that logic, i could say that everyone in the world has at one time done something, premieditated, that was illegal. the fact of the matter is, that action, however menial and petty, is dubbed "illegal" by the powers that be in that nation. but the realist would see that their trivial action most likely didn't harm them or anyone else...so why bitch about it?

seriously, i don't mean to start any arguement or bring any attitude, i'm just speaking frankly that what you posted was probably the one thing that nobody wants to hear and could care less about. but its a public forum and everyone is entitled to his/her opinion.

peace.

No problem. Linebckr49
My purpose was to just to make people aware of the EPA law and rules and regulations on it that did not know about them.
They were setup under the 1990 EPA clean air air act but as far as I know they are still in affect.
And yes some people do want to hear about them.
But I am not trying to enforce them.
Or saying they are good or bad.
Just making people aware of them.
Yes there is a lot of mods out there some good and some not so good.
But Mods should be chosen with care.
Just hanging on a mod does not always mean more MPH or HP.

the reason why im asking is because i have alot of upgrade mods in my car such as tbe,fuel pump,fuel regurlator,fuel injector,ignition upgrade,fmic,under drive pully,k&n intake,13g turbos,greddy boost controller (at 20psi/16psi to redline),rps racing cluch and flywheel,greddy bov and also have a apexi afc now the afc is good but i just want something could change everything such as timing and rev limiter not just air/fuel.but what do you guy's think is the apexi afc good eough for my mods or ya think i need to upgrade my ecu?if upgrading my ecu what would be best with a reasonable price??

[Igovert500]

Linebckr, MT's advice does apply to the original poster more than you or me, because he lives in Cali, and they are a hell of alot stricter there about mods. But seeing as he already has modded his car quite a bit, lol, whatever.

For 13Gs afc is plenty IMO. What injectors you got 450ccs? You don't really need timing control until you go past 550cc injectors. I mean, yes it's nice, you maybe able to advance your timing a little up top for some extra power, but hardly worth that kinda money.

TurboBob on 3si does rev limiter upgrades if you want/need it. If you really want timing control too, Greddy emanage is probably the way to go. I think Apexi has some timing control piggy back as well...maybe an ITC or something like that. I believe they stopped making them, but if you do some searching you maybe able to find a used one on 3si or ebay.

Anotehr option is a MapEcu. Now I only know of 1 3S member on this board that uses it, and I don't know much about it. But that would be another option for a similar price, and that is adjustible (so in my mind, a better thing). Also don't know how that will effect inspections on your car. If you have a 96+ it might cause serious issues because I'm not sure if it's OBDII compatible, etc.
