Hey guys, I am new to the site...not only new to the site, but pretty much a newb on EFI systems in general. I own a 1984 Chevy S10 that was orignally equipped with a 2.8 carbureted engine. It now has a 3.4 crate engine in it and I just completed my first EFI TBI swap ever on it by installing a modified factory harness from a 1987 S10 and an 8062 ECM from a 1991 2.8 S10 with the ASSB chip. I know this is far from optimum since the 3.4 was never installed in the S10 and the only thing ever sitting on a 3.4 similar to this wasn't a TBI but and SFI intake on a Camaro (but it runs really damn good!). Not only that, the crate engine does not use the Camaro camshaft and there are a couple of other minor differences. The intake on this truck is also bored to match a 4.3 TBI unit from an Astro van along with 4.3 injectors in the housing. She is a real Frankenstein! Wanna go ahead and make a shoutout to my buddies from the S10 forum that helped me out and to damanx for phone support when I couldn't get that bastard to start initially.
Okay....let's remember that JK is a total newb. What is the simplest program to try when tuning? Let's dumb it on down too. Tell me the basic process of getting started. Connections, setting up the software etc....making my first changes.
Can someone explain code masks to me?
Thanks guys for your help.
