I am having a problem with the Tire and Gear Wizard No matter what size tire i put in the wizard it puts current at 20.12 with 3.23 gears. If I change the gear ratio in the wizard it changes the tire...

So now no matter what size tire i put in the wizard it puts current at 20.12 with 3.23 gears. If I change the gear ratio in the wizard it changes the tire size. if I put 4.11 it changes the tire...

when I put in the 26.5 with 3.55 gears I get this attached

104176

when I put my tire size in the Tire/Gear wizard it enters another number. My tires are 26.5" and the tire wizard enters tire size as 20.12". I am having problems getting my transmission because of...

I made the changes to the tune. It is running better but the scanner vehicle speed is off by more than 10mph@ 60mph. if you look at 9.24 on the log you will see that the transmission shifted from...

Thanks. I have made all the changes. I will try to get a log later today.
Again thank you very much. I am totally new to this.

Can someone tell me if my fuel trims and my timing looks okay. I get a miss under load at higher RPM's

Thanks. I looked all over for the wizard. That looks like it will fix the calibration.
hopefully that will also fix the transmission shift points
Again. Thanks

I have a 1969 GTO

Also I back pinned all of the pins on the throttle body. And got no deviation at the throttle body when pressing the pedal Or moving the throttle blade by hand.
The pedal seems to be working...

Okay I went through the wiring harness. All wires are where they should be. There were 2 wires on the APP that were crossed. I fixed that. Following are the readings are what I got on my multimeter....

I have confirmed I have 5v to the blue wire at the throttlebody. I have scanned the car, and get the folloeing readings

Throttle position sensor 0.0v (no matter where the throttle is)...

I pulled 5v from C3-15. I have 5v on the blue wire at the throttle body. But nothing else. I am afraid the wiring harness is messed up. When I pulled off the back shell there were 3 in terminated...

The pedal seems to work fine. I have nothing at all at the throttle body. No 5v ref. Nothing to TP1 or TP2. Nothing to any of the pins at the throttle body connector.

Is there supposed to be 12v supplied to the TB? If I put the pedal to the floor wil I see 12v to any of the TB pins

What should I be reading at the TAC motor control pins?

Yes I verified to the ECU. I will run a from the C3 connector. It is almost empty. Thanks

The pinouts for the APP and the throttle body are correct. I have 5v to the pedal, and the position sweeps when depressed. I do not have 5v to the throttle body, in fact the throttle body doesnt...

This is how the throttle body is wired. I for got to mention I am using ls3 heads and manifold anf throttle body. I tried to find a pin out for the ls3 throttlebody, but couldnt find any...

I will go through the whole pin out in the morning. Thank you for your help.

I am using the TBSS pedal, but I am using an aftermarket gold blade throttle body. I can move the throttle body by hand and was able to move it with 12v

Here are the current DTC's
0x7E8: P2119 (Pending, History)
0x7E8: P2135 (Pending, Current, Old, History)
0x7E8: P2138 (Pending, Current, Old, History)
0x7EA: U0100 - Lost Communication With...

I have added switched 12v to C1-14.
Now when Turn ignition on I get flutter from the throttle body and then nothing.

This is an aftermarket wiring harness. I have had a lot of problems with almost every aspect of the process. The company is out of my local area so logistics have been a nightmare. the customer...

LS2 swap good pedal but no throttle movement
Just swapped an LS2 from 2006 TBSS. Disabled VATS, other than that the tune is completely stock. The pedal voltage sweeps when depressed, but no throttle...
