Been doing a lot of reading up on this forum and others and finally decided to write my truck. I pretty much copy and pasted from the REPO's i could find that relate to my s-10, (98-00 s-10's, sonoma's, blazer's, jimmy's, sierra's and silverado's) and went from their. Took it out a few times to adjust the tune every time till i got it the way i like but seems i could still do more adjusting. I know i need a wide band to get the fine tuning done but im just trying to do the best without one for now. If any improvements or changes need to be done let me know please still trying to figure things out mainly AFR, like why does it drop to 12.0 @WOT ? that means im running too rich ? 12.0/1.207=9.942005 is that bad ?
