    I am using new Deka 60 injectors. I’d have to look up somewhere what my stock injectors are.

    someone else with more experience may correct me, but i think the ratio method is a good place to start. Should get you close enough to run the car at any rate.

    I think my stock injectors are 32# if I’m not mistaken. I’m not exactly sure though how to get the correct number from the Deka 60s???????????????!!!

    60/32 is 1.875. Multiply the flow rate in injector flow rate table by 1.8.

    If you are also doing e85, the injector offset should be multiplied by about 1.3 . That should be enough to get your car running.

    Every fuel type has its own stoichiometric value. But all your wideband cares about is lambda, which displays as 14.7 on your gauge. Lambda is the same for all fuels, optimally being 1. But your pcm is calculating everything based on 14.7. if you change this you will also affect other tables that either need to be changed or probably some that we don't have access to. So best to just leave it as is and tune as you would.

    Ok my Injectors flow rate table is as follows 84.4-101.1.

    I put cylinder gain @ 1.2251

    That’s what I have so far. Anything else to set??

    I can’t get it running at any settings. Frustrating is what it is all becoming. I thought the settings were all good but it turns out that they are wrong. I’m going to have to find someone who is not afraid to help with the whole situation. Someone please help from the beginning to the end.

    I multiplied my fuel injector table by 1.8. I put the injector gain÷ injector screw to 1.2251. It will not stay running like this! Anyone have any suggestions? I’d like to get this driving. ASAP!

    Your injector table should be about correct, assuming your car was supercharged from the factory. If it wasn't, we need a different calculation. Also, make sure your injector table was 100% stock before you did the calculation.

    Your injector skew should also be set at 1.34.

    What is your injector settings? Trying to compare. This thing does not want to run!

    This starts right up but will not idle at all. I’m not sure what is going on here. Something is not right with the numbers I multiplied the stock against.
