Looking at my log files my pcm commands a shift at the "set" shift point but the trans isn't shifting till maybe 200-400 rpms later. Is this normal? I would think not...

 

not sure about this cause i had my tuned by Doc of Efi Alchemy. mine shifts dead on 6000 everytime which is what its set for, not before or after. i think they call it "zeroing out" the shift time.

 

mine are zeroed out

 

thats not your shift times, lower your mph on your shifts if it is shifting too late

 

Lowered my shift by vss from 84 to 83 but it was holding till almost 90

 

how many gears shift as per your tune? which one is the one your having issues with?

 

2-3. Have to wait until I go to the track to check out the 1-2.

 

you can't check 1-2 on the street?

 

Nah, it roasts the tires and hits the rev limiter a few times before the shift. Well, I probably could see when it's commanding the shift and when it's actually shifting, but I would think it would be more accurate with traction.

 

1-2 shift is strong on mine but 2-3 shift is delayed and doesnt kick in.... I have a shift kit. Is this a common problem? Any solution to your problem? sounds similar.....
