Can't get the Tacho working with EDIS
Posted: Mon Jul 25, 2011 4:21 am
Hi
I know this forum is for GTV6ers, and my case refers to a GTV4, but I'm hoping similarities with the Alfetta tachometers are consistent enough for someone to be able to help me.
I tried posting elsewhere but nobody has responded. This is my final try, so I hope someone out there can help.
I have almost completed my MSII build and for ignition I want to control an EDIS 4 module with it.
I have recently installed the EDIS but without the MSII to control it, I just have it running in default mode (i.e. 10deg advance).
The problem is that I can't get the Alfetta tacho to work from the EDIS 4 controller.
I tried the CTO and IDM signals but no bloody good.
I read a post in a BWM forum that mentioned using a .22uf cap to filter the signal, I tried that but still NBG.
I tried the circuit mentioned in the Megasquirt manual - with the 2 diodes and the zener diode but still NBG.
Has anyone got this working on their GTV6?
If so how ?
thanks in advance
Sam
