Hello
I have a 95 GMC Van with 5.7 and an automatic transmission it has a 3.42 gear ratio, the van gets about ten mpg.
My goal is to get better mpg, I would like to see 19 mpg.
I would also be interested in Lean cruse mode.
I have done a routine tune-up, set the timing, changed the plugs, repaired the known vacuum leaks etc.
I will start data logging after build a cable or buy one.
I have not identified the computer installed in the van, it's very hard to get to.
1. I am using Windows 7, Is this going to be ok?
2. Can I use a usb for data logging?
3. Should I download both tuner pro and winaldl?
Please post a few links to get a noob started.
Thanks
