I need help, no tiiming? I have a 2000 ss, auto, maft, pase 85 maf, stock throtle body, hooker l-tubes, no air or egr, and scanmaster. The l-trims are at -2-0, and the o2s are at 89#-910. I have to put my maft to 0 at base and wot to 14% lean. The car is really rich. There is no knock being shown but, the car only has 22-24* of timing. I can not figure out where the timing is. Any suggestions would be great and appreciated. I was told to get the ls1 edit any play with the injector rates (that my timing is low because of the large amount of use with the maft). Will this help or is there something else im missing. Thanks..
Re: I need help, no tiiming? Your car is running off the low ocatne timing table b/c you have the MAFT adjusted so much. The motor thinks you aren't getting much air. Only way I know to fix it to get custom tuning. If you have a ported MAF, switch back to stock,adjust your MAFT again and ATAP it again.

Re: I need help, no tiiming? Also try importing your ATAP file into EXCEL. I was ATAPing my car and never say any KR yet my timing was always around 22-23deg instead of the 28deg on the 00' PCMs. Once in EXCEL you coul see all the KR I was getting. My low octane tables dont go all the way to 22deg so I know it was not going to that table so my timing had to have gone somewhere.
Don't ask how I fixed it because I havn't yet. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> I have a guy flying up to do some custom tuning with my LS1 Edit. Half my KR is false the other half is octane oriented.

Re: I need help, no tiiming? Thanks alot. I think I found my timing. I put the translater at 10% lean and now I have 26*. The o2s are showing ric at 920 ish so I think that that is where rest of my timing is. I guess it is ls1 edit time. Thanks again!!!! <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
