What stall converter?

I wonder how much payouts for the pro street are. Also wonder what fast trucks will be there.

Where is this located, is it the billet setup or the cast?

The grounds are sent out by the PCM. The truck is still running without issue last I heard from the customer.

I was able to drive the truck around with the 2nd pcm for about two days without issue. I found a ground that has two in on one side and three out on the other that lays right up against the 5v signal. The grounds are for the 5v references elsewhere in the truck. I separated these wires because...

I tied all the grounds on a separate PCM together and the 12v powers and put them on the battery. Then I pulled the two wires out that go to the ICP sensor. The Sensor ground and the sensor 5v signal. When doing that.... the truck does not mess up. This leads me to believe that the signal return...

Yes. I have the logs at the shop. The numbers were good but I will post them up.

I am going to take that wire out of the pcm harness and install my own that goes dorectly from there to the icp sensor tomorrow.

The bottom yellow line is the sensor ground. The blue line is the fake icp sensor voltage we made with the pot. The red line is the 5v reference to sensor. The crazy line is the icp reference to the pcm. This wire we de pinned out of the plug and still was sending erratic signals!

Yes. Pins look perfect.

The entire IPR. Including solenoid.

I have pulled the entire harness apart and found nothing. I also checked continuity from end to end without issue. I also changed the IPR without change.

Well I have a truck here in the shop and I have not experienced this issue before and I can not for the life of me figure it out. I am hoping someone on here can give me some place to turn. Here is the story: Truck went to another shop before coming here for the same problem. ISSUE: Truck rpm...
