Same problem as before...and now STILL does this with the AirDog150 installed.

On my way home tonight i wasn't on it too hard, gave it 1/3 throttle up a hill and then turned. Upon resuming acceleration the truck started jerking when i'd give it gas and if i gave it full throttle it had nothing. It actually was slowing down like i wasn't on the throttle at all.


It would go ok if i gave it less than 1/4 throttle, at 1/2 it began the jerking, and at full it did nothing. Kinda like a bog sound.


Any ideas as to the problem?


How do i make a log in EFILive of this activity??

Is the FPRV shimmed or have a race valve?

Stock FPRV, but it doesnt make sense to me that it runs fine at first and only after being run hard it seems to develop this condition. Even with a lift pump in.

Your spring inside the FPRV could be very week and pop open... I would put in a Race Valve ASAP. without shimming or using the Race Valve it is impossible for LLY's to make power

the two tables(1 each on a lb7 3 on lly and newer) corispond with fueling prior to a shift and fueling imediatly after a shift.

too much fuel after a shift creates a jumping/lurching shift

too little fuel after a shift is commonly called defuel.

b0741(before shift) throttle limit injection qunatiy and b1103 (after shift) base torque on lb7 LLY has a b c tables for each along with lbz and lmm

pids
fuelq_main_dma is the TLIQ
dmax_trq_dma is base torque

long way about it is long the point at 1/2 thorttole then trace the tables to find out what need to be increase/decreased to make things smother

No logging at all.

It is not the de-fuel tables either.

If it were, it would perform this way at all times, not just after being run hard.
