Thanks for all the answered questions.I fired up the 56 today and the lq9 sounds good ,its running thru edelbrock stepped headers and flowmaster 40s,hopefully it will be on the street in a couple of days. I do have one more question I am running a electric fan and not sure which pin on then 04 pcm controls the efan relay?
I believe its the 42 pin
If that pin is activated in the tune...
Low speed is C1-42.
Get your MIL and OBDII worked out?:dancenana:
Thats awesome, get a vid cuz i wanna see that thing move.
I still need to run 2 wires for the extra speed sensor on the 4l80e ,find a switch to release the TCC and reset the tune for the 4l80. Hopeing for a test drive by the weekend.I figured out the data wire was on pin 58 and I'm not sure what the data on pins 14 and15 are for.I am using a 2 speed fan I had from my wrecked 96 bonneville ,I am going to run 2 relays I took off with it and hook one to pin 42 and the high speed to pin 33 and have it kick on at a higher temp, not sure but I think it should work ok.This project has been a pretty big learning curve for a guy who started out working on 283s and 327s HAHA!
