Re: Changing the ECU to a MegaSquirt II
Has there been any progess with the Megasquirt?
I have several local subie friends telling me that it is the best way for me to go and I was curious if anyone has tried it yet.

Re: Changing the ECU to a MegaSquirt II
As far as I know, the MS is simple enough to setup but the biggest issue is the with tone wheel for the crank/cam sensors. Did the MS create an adjustable trigger type yet??

Re: Changing the ECU to a MegaSquirt II
I setup the MSII on the SVX by simply remving one of the teeth on the crank sensor. Then setting it up as a 12-1 sensor (I think).
It's not perfect, and an additional sensor would be helpful, but I think it struggles with the SVX cam position sensor. The only tradeoff is that starting it takes a few more revolutions than you want as it needs to go around twice before it learns where it is. Matt |

The starting is the same with the Hydra as well... Takes ever so slightly longer to fire. Were you able to use the SVX ignition coils and ignitor? Tom |

Re: Changing the ECU to a MegaSquirt II
Hi Tom,
Yes, I cut one tooth off...the MS uses this point as a refererence then. You simply tell it that the gap is a tooth...if you know what I mean. It operates as if there's 12, but when the gap goes past, it substitutes the gap for a tooth and uses the gap as well. We initially got it going using the standard SVX ignitor and coils, but then had some dramas, so built the MS with some coil drivers on board. We still use the standard SVX coils. Ultimately, due to their cost, we were going to go to a cheap Bosch 6 post coil and leads...but never got there. Maybe this year. Matt |

Re: Changing the ECU to a MegaSquirt II
Oh and SubieatNZ...I used Link a while ago. Back when they had hand controllers, and I wasn't impressed. I'm sure they've moved their products on from then, and I don't like people who say "back in 65 I tried one of their products...they can't have changed".
However, in the age of MS, and open source, it's hard to think you pay for this? There's guys out there working on the code for MS who have real world experience. Matt |

Re: Changing the ECU to a MegaSquirt II
Understood, I had assumed that the unit would use the cam signal as a reference point.
Any ideas on where to stock coil's dwell becomes an issue? I have been meaning to mess with it a little but wonder if you have a better idea. Tom Quote:

Re: Changing the ECU to a MegaSquirt II
Does 2.3ms at 12v make sense?

Re: Changing the ECU to a MegaSquirt II
Yes, sounds about right, but I have been pondering what kind of dwell we can get out of the stock coils before they go bang... I have been running abot 2.0ms for the most part w/o adding up all the trims.
