Well, go with me for a little, and if you can help and test some things out please do. Just read this and try it yourself lol
This has to do with lean hot restarts, I dont think this is going to fix cold starts but those arent bad with the help of the OLFA.
I left my IAT sensor out of my car, and measured the resistance on it at ambient temp (2.30, no Idea what it was really lol I just used the same setting on the multimeter when checking my resistors). I let the car sit after running it for about the time it normally takes to lean out on me (although I am not 100% sure if it was but I am about to try again with the heat soaked IAT sensor).
Ambient temp here today is 83*, I was using resistors that commanded 79*. I started the car up and it was no leaner than about a 15.0:1 and showed no signs of leaning out when on the throttle like it did before. With all the startup enrichment I have in the car right now, it acutally had a hard time starting, which is good becuase it is way too much fuel.
I just put a bunch of resistors in series until I got the right resistance. If you guys can try this, please do and get back. Make sure you plug the resisotrs into the IAT connector BEFORE starting. Last time I tried this with a cooled off IAT I did it after I started the car. I am going to see if the car starts lean with the heat soaded IAT plugged up. If this helps out, I am going to just put a resistor in there at the temp I tune the car at and leave it. It will go rich on hot days now instead of lean hopefully. Hopefully this is a temporary fix and can be taken care of correctly once we get an IAT VE modifier.
Please post up your results if you try this. This is the first trial at this so I am not 100% sure it will work.
