Limitations of Toyota COP
#4

For those that are hovering around a bar, I know there's no power limitations here to warrant the LS2 coils.
However, I haven't bought COPs yet and I'm on the fence about LS2s because I think I can source COP or LS2 for around the same price. Still worth it to go LS2?... or at this point is my justification purely based on future upgrade potential?

Hmm, I was under the impression that my ecu does not output a tach signal and the tach is actually driven off the coil. Toyota COPs also have a tach output wire on them, but none of the lsx coils do. So in order to run lsx coils I would have to make a tach output circuit.

Yeah, you found the right thread. It's a modification inside the MS, but it's not a hard one.

Yeah, i guess i didn't word that quite right. Glad I'm not crazy, as that was the deciding factor for going COPS vs LSX coil. I'm sure it wouldn't be that hard to add, but i really did not want to mess with it and I'm on a stock motor anyways, so no real need for 300+whp capability.. yet.

Sure it might not idle as nice due to the large injectors, and you'll probably have to have an aftermarket solution for boost control.
Plus if the Toyota COPS don't output a tach signal, the MS1 can.
