hey guys i got a question about a Replica JWT ECU from ebay

[maxZpak]

do those ecu really work here is an example>>>http://cgi.ebay.com/ebaymotors...d=1,1 because i have upgraded injectors and an SAFC will that ECU do anything or screw anything up like my SAFC? if i buy and install it.

ECU chip replacement has rapidly become the easiest, and most efficient modification available to increase horsepower power and torque.

Designed for use on stage 3 cars (high performance air filter, boost jets, cat-back exhaust are a pre-requisite). This ECU upgrade removes the speed limiter, raise the rev-limiter to 7300 rpm, and adjust the timing & fuel maps for up to 17 PSI of boost!

Prevents detonation when running higher boost. Allows a better air/fuel mixture to be burned with the higher boost. Also make sure your base timing is set at 15 degrees.

Your car can do over 400-rear wheel horse power with this ECU chip upgrade.

Taking full advantage of 91+ octane fuel, Performance chips unleash more power by reprogramming the fuel mixture and ignition timing parameters of the engine management system.

Well, considering these claims will actually blow your motor eventually if you still have stock injectors (unless you want to run at 100% duty cycle forever). It is "feasable", but doing over 400WHP with only that is silly.

Pistons work better when melted!!

Todd brings up another important issue...to do this safely and consitantly you'll need some forged pistons. Although there have been guys making far more power than that with the stock steel sheathed (with large oil squirters) pistons..they also had other parts on the car..such as bigger injectors which will of course allow you to not lean the car out and cause serious damage.

Well I have nismo 740 cc injectors in my car and a tuned SAFC so i was wondering if I put this chip will that mess anything up on how my SAFC is tuned? I have a cat back exhost/ SAFC/ Upgraded nismo Injectors

[WidebodyZ]

It "states" the fuel maps are modified so I'd say you'd have to re-tune or remove your AFC. AFC's don't really do all that much as far as fuel tuning..they are only for mild adjustments and not meant for total fuel control.

I thought the safc-2 cant handle injectors past 440ish

Ditch the SAFC and get a real tuned ECU.

"Band-aid" mods can only lead to disaster.

by real tunned ECU u mean JWT or Z1 correct?
