    That's what I was thinking but I wanted to make sure. This does bring up one other question though. If I don't have PE enabled at all Will I still be able to run into the upper range of the tables. Won't that run at 14.7 afr even up at redline? I apologize if this seems like a dumb question. I am late into the tuning game I know. I am just trying to gain full understanding of this PCM.

    What do you think about using filters for PE and TPS? I was going to use [PID.17]>22 AND [SENS.121]>14

    After loging some VE error the last couple of days. I noticed something today. I noticed my table is initially off by 25% according to the log. So I multiplied the whole table by 1.2 just to see if it gets me closer. Well it looks like the first row starts to line up but everything else is staying at high teens to twenty's. I am changing my tables. Does the afr error percentage on read up to 25% or am I loosing my mind. LOL I cant Believe this table is that far off. I regret ever getting this mail order tune. I know we use ethanol around here. Up to 10%. But still I cant believe this is that far off. Sould I just go with a stage 2 tune and modify that at this point? The Maf data wasn't this inconsistent.

    Think I am going to find a stage 2 VE table and start over. This table is so far off its ridiculous.

    Can someone look at my tune to make sure I didn't miss something for VE tuning. I am starting to feel a little retarded. I am going to unplug my MAF as well. My Maf doesn't seem to be failing properly.
