We swapped a 2015 LFX into a Miata for a track car. Gutted and caged, no smog equipment.
The Drivetrain came complete from a 2015 Camaro LFX manual with a matching E39A ECU
It starts and runs up to about 5300 RPM. I went to a tuner that has tuned our Ectotec Swapped Miatas.
He thinks it's because we didn't have the VSS (Vehicle Speed Sensor) hooked up. For the Ecotec swaps, it wasn't needed. We are adding the vss next thing.
I attached the tune and a log file. Any help would be appreciated.
Thanks
Jeff
