Is there anything i need to do for tuning when i go from a 4l80e to a th400? My speedo is taken care of but i seem to have timing being pulled from somewhere....Could this be in the torque managment section? I have looked and IAT's are not the issure and coolent temps stay in range also.... I wish this software was a little more user friendly for the amount of money it cost! Im also having a problem setting up my afr error histogram because i have a autometer cobalt afr gauge that is a custom pid and i cannot seem to get the string right to make the right % show of the difference in commanded and actual afr which really make tuning a pita, if anyone has experience in this field please let me know and i can get you a copy of my scanner file and tune to help me... Thanks alot in advance

 

i got everything figured out on the timing issue and custom pids, but still dont know if there is anything i need to do just becase i swapped trannys..... Seems like its running fine i was just curious... :]

 

I was curiously watching this thread. Care to share any of the details so far?

 

i dont mind at all, if its about the histogram im gonna have to call ya on that one... The timing issue was burst knock, i never had it untill i put solid mounts and a cage in the truck.... If ya want me to give ya a hollar just shoot me a pm with your number and ill help ya out, you have the cobalt autometer afr gauge too huh?

 

Well, I was just wondering if there was anything weird and informative you could post. I don't have anything with HPT and a t400 right now so the info wouldn't likely do me anygood at the moment.

Burst Knock was one of the first things I had to get rid of on mine. Took me a while to figure out where the timing was going.

 

I was going to mention Burst Knock as well.

peace
