ok there you go actin smart about something noones asking about its like talking about how u process cheese,(noone cares) and secondly i never asked u for help i was being sarcastic bc u were actin like an ass to someone else who needed help... and a spec v engine is none of the above listed so b4 u start spouting off like a retard encounter a QR25DE then spit out all that yac yac knowledge u think u have...and im done having this lil internet beef with you bc its pathetic and pointless bc if i were to see you in real life you wouldn't dare try me... :fluffy: so do like fluffy and turn around.toolapcfan said:I've yet to encounter a computer controlled car that doesn't have a wire from the coil to the ECU for a tach signal. All B13's B14's and B15's have a wire from the coil to the ECU. They also all have a wire out of the ECU that is intended for connecting to the optional OEM tach. If you know more than I about this, why are you asking me how to hook a tach up to your car? I've helped other people wire a tach in their B13, B14 and B15, you obviously have not, hence why you're spouting off like a retard again. I've forgotten more than you'll ever know smart guy.
