ECU Question
Hey guys...
Im having trouble getting my hands on a stock B13 ECU and I need it ASAP, and I found an ECU that came with an Avenir motor I purchased a few years ago and surprise, its not an avenir ECU, I looked it up and it turned out to be a 91 G20 ECU and I was wondering if it would work in my B13 SeE-R...

I need to keep looking and the car is in the shop right now so going to just bolt it up isnt an option right now and I really need to see if it works or not...

Thanks for the help guys

obd1 g20 ecu's will work in your b13. but since your boosted i recomend on having a proper tune for your set up

Oh ok thanks man, thats great news

Nah, Im not boosted any more

Im going back to stock DE but keeping the DET engine just N/A, at least for the time being, later I will buy a 10:1 DE, but I need the stock ECU, is the only thing missing hehe...
Damn Im gonna miss boost, and with the low DET compresion on N/A car is gonna be slooow

well the g20 ecu is actully considered a upgrade then.. higher rev limiter (about 8k) and no speed cut. since your a lower compression n/a you can attempt to make up for some of your loss by running more timing, just run the proper octain fuel

Oh nice, higher rev cut sounds good...
I will be running a VVL manifold with 2.5" muffler...
I was considering spraying it to have some ocasional fun at the track, can an N/A DET handle 75 shot or will it be better to stay at 50?...

i sprayed a 75 wet on my jdm de and it loved it... i even ran it over timed at 19* on spray while spraying off idle and it loved it... my buddys also running a 70 dry on 11* of timing and its holding on his 10 to 1

Sorry to thread jack,but will it matter performance wise to use an auto g20 ecu in my b13? will there be any issues besides it throwing a tranny cel?
