Hey guys, this will be my first post here. I've been over a bunch of different forums the last few months and yours ends up having the most to contribute. I like the varying nature of programming here.
Here is my vehicle:
1994 GMC T15 Jimmy 16196395 BHRJ ECU (I have a few different ecu's, this is the one on my desk I'm working with)
4.3 CPI 4l60e 3.42 gears 4x4
Like most of us I wanted more power so I purchased the 10psi wynjammer kit. It was awesome but the belt alignment issues frustrated me. The noise frustrated my wife, and the fear of a lean engine destruction condition tipped the scales.
I sold the kit and decided that an LS swap was in my distant future. I'll drive her as she is until the engine explodes and then do my ls swap.
My programming goals:
Kill ac compressor under certain conditions: EG: overtemp, WOT, etc
Control electric fans based on many variables (I found some programming online that does exactly this)
Valet mode, winch mode, sleep mode, etc.
Wideband feeding the ecu: I'd like my ecu to read my wideband directly instead of it's emulated narrowband output. (MTX-L)
We do a lot of camping on off-road trails. We want to sleep in the car on hot nights with the ac on but worry about overheating the engine. I saw some code that would idle the engine up when the voltage drops to help with winching. I am working on a dual alternator mod placing an auxiliary alternator in the smog pump position (bracket I scored at the junkyard). Hoping to be able to possibly have the ecu control the second alternator as well.
Anyways I just wanted to thank you all for the 200+ threads I've read through. I've already come away with a ton of knowledge and hopefully can share what I learn with others to help them out.
Added a picture of my baby hooked up to a uhaul. Helped a friend move from Houston, TX to Atlanta, GA a few weeks ago. 75mph @ 11mpg running 12:1ish fuel ratio in D. I'm guessing this is "power enrichment". Reduced speeds to say 60mph got me back to 14.7:1 but would every 3 seconds or so hit 12-1. LOTS TO LEARN STILL!
