Ok, the car was running great for a week. Now all of a sudden after Monday the car has run progressivly worse and worse and now when in drive if I give it gas the car wants to die and the AFR go's dead lean? And now I don't even have a cam sensor signal? I have replaced the cam and crank sensors and still runs the same. I have checked the grounds and even added a few more to no avail? Any idea's?

On the dash on the bottom of the screen (cam/adv.) it is not moving.

Is the "override cam sync test" box checked or unchecked?


Follow the directions in the BS3 manual to measure the cam signal at the harness. You should see the output be +12V for 360* of crank rotation and 0V for the next 360*. It should flip from +12 to 0 around TDC when #1 is ready to fire.

Let us know what happens.

I just got off the with John at BS3 and he said the reason it is not doing anything is I don't have that function. He logged on my computer via internet and went thru the ecu and tune and didn't see a problem.

I assumed you had something in cam/crank adv before. You need the newest firmware (released earlier this year) to see the actual cam/crank advance.

if you do the voltage test I posted earlier, that'll tell you if the cam signal is being sent to the ECU properly.
