After some epic failing building my megasquirt I now have it running the car. But I think I am now the proud owner of the worst missfire problem in history.
The attatched log shows the classic megasquirt tach dropout that some people have at certain rev ranges sometimes that can be a bit annoying. Mine starts at idle and stays till redline. Oh and its all the time
Now Joe thinks that I may have a noisy signal from my CAS similar to the one that caused him to kick his to the curb in favour of a crank wheel (something I am seriously considering) I have just hooked up my simplistic computer scope directly to my CAS and had a look at my signals.
Now I'm not sure I can see anything wrong with them.
I followed Brains how-to to the letter with regards to mods.
Can someone who is far cleverer than me please suggest where I may have gone wrong in my build?
Also I have heard something about a "dave cap" that really helps sort out tach spikes but I cant find much info on it ( I think its either been incorporated into the V3 board or dropped) any one learn me on this?
If any more scoping is required please let me know, I think it might be a good idea to check the signal just as it enters the MS to make sure the wiring isn't horrid.
Thanks in advance
Hoping not to be down the scrapyard looking for a 36-1 wheel
