That setup should probably pull around 12 mpg mixed.

Sounds like your tune is ****. And the converter not locking could definitely be due to false misfire from the cam. I set my low limit detect to 1500 rpm. That should take care of that issue.

 

Do you not have a wideband?

 

yes but i havent had the bung welded in yet.

 

played with the misfire tables. i can keep the stall locked now but only when the truck has a load on it. either if i am accelerating or climbing a grade on the highway. the second i pull my foot out or start to go down hill it unlocks. what am i missing i dont see anything else i can play with to keep it locked up.

 

Like mentioned, you need to understand what the minimum throttle release tables do and how they function. Read the descriptions carefully and see what you come up with. Post a screen shot of what yours look like and I'll nudge you in the right direction.

 

Refer back to post #5... Did you do anything to those tables?

 

its not letting me screen shoot the tables. once i figure it out ill post up the settings.

 

nailed it. i used the program and it didnt change those tables so i left them alone. i will install that this morning and see how it drives. i cant afford to blow up anything else right now so screwing up is not an option.

 

 

OP, you have been told like fiddy times to change the minimum throttle release settings. We keep telling you this because we know what we are talking about. We've all been through it with our 4L80e's. Fix those tables, and close this thread
