speed signal m52 2.8

[Sx279]

hi i'm halfway though my e30 2.8 m52 track car build and i havent used the e30 clocks as a matter of fact i havent got any of the e30 wiring anymore.

ive got two questions

1.
speed input to ecu

i dont want to use the e30 clocks at all i am using after market gauges [rev,temp,oil pressure,volts ect]

anybody got any ideas how i can get a speed signal to the ecu with out the clocks?

the engine runs and every thing but i have not got the rev counter in yet to no if its going to 7xxx or 5xxx

2.
what pin on the e36 loom's x20 plug would i need to run to my rpm gauge?

thanks..

Q1. Pin 15 on the ECU. i was in limp mode cos the speed signal wasn't wired up.

did a loom bypass and pin 15 100%

how did u giv a input to the ecu? from the diff?
i would have thought the signal from the diff would be a AC signal the clocks convert it then pass it on in DC to the ecu.

It is, the signal comes from the clocks. I can sort this for you so you dont need the clocks.

Its nothing to do with Pin 15 either BTW

pin 9 e30. pin 20 e36 or ecu pin 15 bypass

dude no e30 loom left just engine loom with my wiring going into the x20 plug



danthe would that be via a remap ? can u pm me your number?
