loss of TFMPRS after OS change
TFMRPS is crap ever since OS swap. Before it would not drop below 200kpa, now it drops to zero when I get off the throttle and shifts are noticably soft. Engin torque values are comparable. any suggestions?
Log 15 is with the original OS
Log 25 now with adapted OS from a 2002 4.8L 4L60 truck

That doesn't look right at all... try enabling the MAF and see what happens.
I think I'll put the old OS back in. It's alot easier than redoing my intake to accept the MAF again.
I was trying to get rid of that induced ripple TCC at cruise. You'll see it at the end of this log. Also, was hoping I could get the TCC to stay locked above certain speeds. You'll notice when I slow to 0% throttle or brake for a corner, I get nasty flare-up. I should have bought a manual trans.
back to the original OS.
tried this OS too. Same difference. plus the battery light comes on
Looks like I'm stuck with the original 09379910 OS
