okay thanx for the tips will look into it further thanx

Yeah my first thought was shit in the fuel pump but why would my digital shift indicator disappear and why doesn't the predator recognize my vehicle anymore? That is where the fried ecu thought came from.

I have the u7198 with hardware upgrade and i was idling at the drive through window at McDonalds when my truck started running rough and shaking the service engine light flashed a few times,the truck died and that was it. I was low on fuel and it wouldn't fire. It cranked fine just no firing up. So ...

I borrowed a laptop to see if i could get my a/f ratio through the data viewer with a u7198 and I need the radio shack usb to serial cable part # thanx

ok thanx

Ok my brake light has been on ever since i put the 33 inch tires on and adjusted the predator for 33 inch tires and no luck so which way do i go now up or down in size?

funny if no one wants more performance out of their 4 cylinder that other companies make headers ,cold air intakes,chips and throttle body spacers for them HMMMMMMMMMMMMMMMMM

plus all this bragging about being the #1 tuner company you would think they would support ALL vehicles

well they got 1 now

dude it rips pulls like a six ,was my mom's she passed away. I have a 496 bigblock suburban so there

I might be picking up a 2001 z24 cavalier 4 cylinder and thought it could benefit from some tuning but didn't see it supported.....why?

Yeah go for it man ,I updated my u7198 and it will save a ton of time while tuning

anyone know if the vette servo will work on a 4l80e?

The lights are normal but not sure how to adjust for tire size

ok thx was reading the dually guys question and got me thinking....scary ha
