most of us use this it will adjust your AFR's, increase rpm limit and more just do the the research on the forum.

i have done alot of research. As i stated I have the old style ecu grey. I have a 2003.5 but up revs EMS only works with 2004 g35 and up. My ecu is not supported by uprev. I either have to go full standalone or use a piggy back EMS. But most piggy backs do not increase rev limiter just changes AFR. I was looking for help to see what EMS can do both AFR & Rev limiter. i have heard of Emanage i have heard of AEM Neo and some others but i haven't yet gotton the answer i am looking for. I want something worth my money.

 

Check the thread at the top of this forum (early ECU technical thread or whatever it's called)...

 

i've been folowing that thread but im begining to think that it is way to technical. I rather tune it for now with a piggy back then when all the kinks in wrked out ill decide to change to the conversion!

 

You can get a UTEC and tune with it. There are options but they are custom. Check out my site.

 

Utec ? Tell me more lol

I make them work on the older grey ecu's, then you can tune your motor.

 

wat difference will this do from something like a AEM EMS?

 

aem and vq35 never really took off that great.

 

All depends on what you want.

UTEC= cheaper, tune ign and fuel,

Haltech= cost more, better tune, cam control


Both would need custom wiring. Ive done both with the grey ecu connector.
