This isn't my car, it's an MR2 with beams engine.
I am not able to look at it as i'm in tas again. :(-
But i'm told the motor is chugginf when you press the acc down. Instead of the engine responding and driving faster it is as if it has no response and then kicks in.
I suggested getting the TPS recalibrated as installing the beams engine could of bumped the TPS position. Any other reasons to look for?
Also another problem, and one that i unfortunatly can't look at. the Tacho needle will fluctuate as if it's getting a signal from something else. acts crazy going up and down. Does this sound familiar to anyone thats done an engine conversion? Is it simply a wire connected to the wrong place? Typically does the tacho run off 1 wire from the ECU?? It seems to me it is getting the signal from something else. Is there a common ECU pin for the tacho? If so whats it called? or even better what is the ECU pin that drives the Tacho on a caldina blacktop beams engine?
