I have a GMPP Crate LS7 Engine installed in a midengine kit car that uses a Porsche G50 transaxle. A wheel with 36 square teeth has been installed on one of the half shafts that drives a rear wheel. A stock GM VSS sensor is mounted appropriately to sense rear wheel rotation. The VCM sends a proper vehicle speed sensor signal to my Motec digital dash/data logger thru the OBDII port for proper speed and odometer readings. Everything seems to work fine. EXCEPT that Deceleration Fuel Cut Off does not work. ALSO my engine coolant fans properly turn on at 203* and off at 196* but do not turn off when vehicle speed exceeds "X" MPH as they should.
I've searched the forum but find no answers to my dilemma.
My questions are:
1. Does anyone have an LS7/E67 running with VSS, DFCO and fan cutoff all working?
2. If so would he share his .hpt file?
3. It is possibly a GMPP issue that has been fixed but I cannot find any GMPP LS7 tunes in the repository. My VCM was purchased several years ago.
Any and all suggestions will be appreciated.
Thanks
