Quick Paxton question

[texastonka]

As some of you knwo my truck has been having an ABS Brake issue that I can't figure out (seperate thread). Since I just got the truck I did not notice this until the other day but the onboard computer is reading that I am getting 21MPG average... In reality I am getting 14 on the highway.

I have gone through the computer and made sure it is the right gear ration and tire size and have replaced both front hubs and all speed sensors.

Is this normal when you install a paxton to have this onboard that far off? Or is it a sign that the rear tone ring may be FUBAR?

Again no lights, DTC, or codes in computer.

Appreciate the input from you Paxton guys!

Larger injectors can throw the computer off.

Yup, like he said^^^^^^ Once you get the larger injectors and the tune, you can no longer use the overhead display for MPG or DTE.

You running an SCT or VEC?

I am going to go a custom wired AEM route in lieu of the SCT or split second etc...

Should I be able to get the overhead display to operate within reason with an AEM?

Use AEM on my other two Vipers and knwo a great tuner here close to home for them is why AEM is my choice...

I think with the VEC the overhead still works correctly, not so with the SCT.
