So I'm going to post this in the drag racing section also but thought I would start here. Is there anyone who who has completely disabeled the traction control/stabilitrac system through the ecu? I've had problems all day trying to launch the car at the track it does great from the 60ft but after that it pulls power like it thinks something is wrong. After I pull off the track all the power comes back and it makes boost again. I've pulled fuses and even tried to turn it off with the button still does the same thing. The tune is on point so I know it isn't that.

You're confusing... "...great from the 60ft but after that..." Are you saying it bogs off the line then pulls great, or launches great then loses power? TC can be one cause if the "on point" tune doesn't have some torque settings disabled/maxed, or burst knock disabled, or... It can be a lot of things. Have you logged this phenomenon?

Here are some of the settings that would need to be adjusted (except Decay Rate):

It pulls hard during the 60' and falls off after that. I did not log them forgot the laptop. Worst part is I did a street test hit and had no issues what so ever it's only when I'm on a prepped surface I have this problem.

Hmmm. Got your tune file handy?

Trob85 · 04-01-2017, 07:17 PM

No I don't it's at the shop.

Just pull the fuses at the track.

I had a similar problem at @700whp. It'll run perfect on the street but bog at the track after the launch. I had the 6l80 at the time and turned out it would slip just enough to do that. No other signs of a bad trans. No burnt oil or anything. Trans is still running good on another 500hp car

I should mention I'm a 4l80 car now.

Trob85 · 04-02-2017, 06:20 PM

Ok so my tune is exactly like shown above all disabled. Here's my question now looking through the tune the gear ratios for the 4l80 are different than what's actually in the transmission could that cause it to read wrong a pull power?heres a picture of the table showing the gear ratio but the actually gear ratio is 2:48 in first gear-1:48 second gear- 1:00 third gear-0:75 4th gear-2:07 reverse.

Those look like 4l60E gears.... I would assume that if it was related to the difference between gear ratios, installed vs. what's in the ECU. then the problem would manifest itself all the time, no matter where you were at.
