Turbo Fuel Management Question

tunglnguyen · 05-21-2005, 06:30 AM

So I've been piecing my turbo kit together and basically have it all completed and found out the worse news in the world today. My ECU is a p72 OBD2, so I cant run a standalone unless I convert to OBD1 and thats extra costs I didnt plan. My setup is a 95 GSR with a T3 turbo, planning on running 6-7 Psi of boost. I was gonna go the Hondata route b/c I know its safe and very reliable, but it seems a little bit too much work and pricey now that I dont have a OBD1 ECU. I just want peoples opinion on the VAFC hack if I only run 6-7psi with the 450cc RC injectors that I already have. I plan on getting it tuned right off the bat with my mechanic that is very knowledgable on a dyno with a wideband o2. Now give me your verdict. Do you think that my engine will eventually blow up or should I be ok at the boost setting?

what about an safc2 and obdII pocketlogger combo??

What is the difference between VAFC and VAFC2? More options?

you can do better than a t3

if you planned on going with a standalone, the $75 obd2-obd1 conversion harness and $150 obd1 p72 should be the least of your concerns, and the least of your problems.

I dont know where you found those prices, but I sure cant find them anywhere, from what I;ve seen its 200 for obd1 p72 obd1 ecu and 120 for conversion hareness, thats an xtra 320 that I could spend on tunning.

a 95 gsr is stock obd1, just fyi. so either your ecu is obd1 or somebody did a obd2 conversion, which is stupid

My motor is OBD1 but my ECU is an OBD2 ecu. That's why im frustrated, b/c when i did the swap I forgot the check the ECU.

from my limited readings of vsaf 1 and 2. they are apexi's vvt propritary air/fuel mangment controlers for honda/toyota varitable valve timming engines. they might be compatable with other vvt cars but i dont know. from what i've heard they work the same way as a normal safc but are programed in a way to take into acount the way the ecu, and pcu changes things in your cars. i'm kind of currious now, i think i'll do a little looking today about that.

what are the specs on that t3?
