another tcc question. please look

[jeff*k]

86 gn stock 87k. i have what i believe is a tcc problem. i can feel the tcc lock-up at around 30mph, which i understand is normal. the problem is when i am going up a hill at 30 mph in 3rd gear with the tcc locked up i can bearly acclerate up the hill. the tcc should disengage right?? for the last few weeks i have been riding the brake pedal when i go up hills so the tcc does not engage. i know this sounds stupid but it works well.
my 84 gn is doing the same thing. i changed the tcc on that car and it did not fix the problem. what gives??

Mine irritates me because it also does not unlock as I would like it to. I have to get on the gas past about 1/3 throttle or so before the TCC will unlock. Isn't there a parameter in the chip for unlocking the TCC at a given TPS voltage? If so, I know I'd like to get my chip redone in order to take care of this as well as the fueling.
I've got a three way switch in my switch panel for controlling the TCC. I decided to wire it so that the up position locks it, middle position unlocks it/keeps it unlocked, and down position lets the ECM control it. This is nice when I go to pass someone and I'm not getting on the throttle enough to unlock the TCC (face it, you don't need much throttle to get going with these cars!). All I have to do is flip the switch to the middle position and the TCC unlocks. I then accelerate around whomever.

so the ecm locks the tc based on tps voltage???

Get rid of the pittbull chip, my opinion, they suck! Way too agressive on timing, lockup almost always, lame idle-------Call quad air, red will make what ever you want! I had him make one for me with a 55 mph lockup (light throttle instead of 45) works pissa! 440-235-3232 EST 10:00-3:00 m-f

mine locks up at 30 and takes at least 1/2 thottle to dissengage.
like i said i drive up hills with brakes applied. so there is no other way to deley tcc lock up??? i really dont want to operate it with a manual swith.

OK, this sounds like a really cool switch...gotta wiring diagram or other hint for us non-EEs?
Thanks,
