i was checking the sensors and read that tps should go up from 0volts to 5volts on the l8 ecu i was told i have a l8 but my tps starts at 5 volts and goes down to 0 throttle full open ?? dose this mean i really have a l6 as when i looked at the inside it looks like the l8 with small extra board can anyone tell me if there another way to identify which i have
