Negative Accell enrich percent?

Post by Jackal »

Hey guys, i am running msnse 029q with ms1 v2.2. I am having an issue with my accell enrichment percent. I get a negative reading sometimes and others i get the percent to peg over 1900% I don't even know were to begin. the below link should enable yo uto download a zip file that contains my latest msq, and a datalog with the accell enrich error. Thanks for any help.

A lot of the acceleration enrichment percentage numbers in the log are rather confusing. If the car doesn't actually stumble or go too rich when you give it gas, I wouldn't worry about it.

It does stumble, but the current numbers in my accell wizard make the car run the best. I ran a 14.14, @ 102mph in a qtr, i was hoping to break 13.9's it bogs a little off the line , and i am almost 100% sure this is due to my error. Thanks for the help, oh and could it be tps line noise? as in need to try to filter, or sheild it?

I'm also having problems adjusting TPSAE. I will attach a log and a tune. most throttle events have my AE going negative, and not adding fuel, and one even shoots up to 2350%! I wanted to add that my MAP DE stays on all the time no matter what. I'm no sure if its pulling fuel or not. The car drives fine but has a stumble that I cant seem to tune out. I've read on other threads that this issue is common on MS1/Extra 029y3. Has anyone found a quick fix for reliable accel enrichment on ms1extra? I put this same post on another thread. i meant to put it on this one. I like to search a lot before I ask questions.
