What color wire did you splice into for the VSS? Did you do it at the sensor or the ECM?

I got mine working today, its from a 2000 jimmy. I used mitchell for my wiring and it kept saying that it has an external compass sensor, so I went back to the JY ripped out the headliner to see nothing. The unit works fine, i just find it that it doesnt folow the contour of the headliner and its too close to my mirror. At first I was going to get the rear view mirror with temp/compass w/ on star lol (fake nitrous button) from an 2003 GM.

Any way to make the MPG readout from the newer consoles work? How is that data received?

Hahaha before I got to page 2 I was going to suggest a 2nd sensor with a switch to report intake temps!! But you already had that idea.

And x2 on the interior temp sensor as well!

Yeah, I figured the lack of OBDII would be the answer.

I wrote a script to run on my laptop that analyzes the output from tunerpro in real-time while driving & it will show instantaneous & average MPG bases off of the injector flow rate, pulse width, temperature, RPM & speed.

But it requires an ALDL cable, a laptop, tuner/scannerpro, apache & php... and it is far from complete. Haven't messed with it for quite a while.

Was planning to do some tests with it to check MPG at different highway speeds, to see how much better 55 mph really is than 85 mph
