Stumble from start

Anything about Ford EEC tuning. TwEECer and Moates questions dominate, but there's some SCT and OBD-II knowledge too.

Stumble from start

Post by EFI66 » Thu Nov 07, 2019 6:19 pm

I got my setup running well on my 5.0 T4M0 when running OL all the time except from when I put it in 1st gear from cold and starts rolling out the driveway. It stumbles and dies if I do not step on the throttle alot more than whats normal.

I checked the logs and see this area where it goes crazy but can someone point me on what to change? I notice the ISCDTY goes from 53 to 99 and the STFT1 goes to 30% but im not sure why? I attach screendump from where it fails

Log as many flags as possible. Look for a change immediately prior.
Cheers
