On fd i have no stock ecu and no extra outputs on ecu
So stuck with no revcounter was hoping some 1 can give me some ideas on making it work

I have wiring diagrams i no what wires to use juat dont want to start connecting it as im unsure if i need to use diods or resistors

What ECU are you using that does not have a tach signal?

imitek

It has but i only have 2 outputs
And they are being used
So im looking for another way to get tach working
Can you shine some light pritty pleass

If you specify to what exactly your using and what those 2 outputs are being used for may be helpfull

What standalone are you running / other engine management mods.

imitek

M2r output 1 is thermo fan
And output 2 will be boost control or idle control

I dont want to use ecu for tach ive heard peope use a pull up resistor from ignitor and attach it straight to tach
Just want to no if any 1 here has done it

Carlos Iglesias did something like you're describing, but also encountered misfires due to a bad wiring connection related to the igniter and tachometer. I'd advise to be very careful if you're planning to try this, and build in a way that would be very easy to remove your wiring additions in case you run into problems.
