Hi everyone,
I have a GM E38 ECU running an LS3. It's a swap into a Miata. I also have a Motec C127 that is hooked to the OBDII port as the vehicle instruments. This is via a custom Speartech harness with two OBDII ports - one to the normal test plug and the other direct to the Motec harness.
The issue is with the Motec connected VCMScanner doesn't work (will connect but nothing displayed), and VCMEditor is hit or miss for read/load.
So if I disconnect the Motec it all works as it should except for the prior tuner setting the VIN to something odd and showing as YYYYYYYYYYY.
Any way to make these two co-exist peacefully as for logging drives I sort of want a functional dash
