I am working on an 01 LS1, I had a good tune on it with Mass air. However I had drop out in vaccuum, so I converted to SD and a custom os.. now I'm having trouble getting the 2 bar map sensor to read right at key on as well as it will not idle. The only way I've been able to get it to idle is if I set the map ofset to somewhere around 50. I know this is not right becaouse offset is to move the scale. what am I missing? I got the autotune up set finally but i need it to idle before I continue. Is there anything special to setting up the boost maps?
there is no ETC, only a turbo that's running about 11 psi ( with Mass air), methanol injection ( only after 4 psi).
Thanks for the help
