Got the tune emailed so I uploaded it and got the motor prepped to be fired. She lit off on the first crank. I love LS motors.

Congrats man! Yes they are awesome!!!

Anyone of you running DBW in your swap have any issues with the throttle body not responding?

I am having that issue right now. I have no + or - at the throttle motor. I have ONLY the CRUISE wires unhooked as of right now. Those SHOULD NOT matter what so ever in the matter. I have my UART communication wires connected from TAC to PCM. I cant remember if I had TPS signal on the scanner. But because it was only running on an engine stand, I didnt want to run it too long. I hope to get back to it tomorrow to run some tests and have check the TPS manually to make sure its reading.

What sucks is that I want to convert to DBC but my 01 0411 PCM does not have the IAC stepper on it. I have already licensed this PCM and do not want to pay to license another one as of yet. If I can not figure out this problem then I will have to get another PCM to run DBC.

Any help is greatly appreciated.

Thank You

All 12200411 PCMs have an I.A.C. driver.

According to this link, with the PCM comparison with and without the stepper, when I opened my PCM, I did not have anything soldered to the board in the same location as these pics.

I have probably owned 200 12200411 PCMs and they all properly ran DBC throttle bodies. Are you confusing the P59/LS1b controllers as all being 411 PCMs?

My PCM has a the 0411 service number on it.

That PCM will run a DBC throttle body.

I am gonna trust your knowledge there Jeff. But...what about the wiring for the TPS? Since that runs through the TAC module, how can I wire that to the PCM? I looked at the schematic through ALLDATA and I didnt see anything that showed the TPS on the PCM. I only saw one circuit number that matched between the two.

According to ALLDATA, It shows 2 different TPS diagrams. Mine is the DUAL STAGE TPS. It has 6 wires instead of the normal 3.

I have never seen a Drive By Cable throttle body with a 6 wire T.P.S. OR Are you meaning you want to use 3 of the existing DBW wires to connect the T.P.S. to the PCM?
