Ok...
I'm converting my basically stock 2.0L (stock cam, euro Ps and Cs) over to microsquirt. Microsquirt is a megasquirt-derived fuel injection computer that's robot-soldered and factory encased in a weatherproof enclosure. The I/O is implemented as a single, 35-position weatherproof connector. The whole thing is about the size of 2 decks of cards. The system I'm installing was engineered and supplied 100% by McMark. My understanding is that he usually provides these systems for motors that he builds, but I talked him into providing one for me. Below, I will document the install details here for anyone else who talks McMark into selling them a system, or who attempts something similar someday. DISCLAIMER: I won't provide model numbers, prices, or any other info like that in this thread -- please contact McMark directly for those types of details. All I can say is that you get what you pay for and this is a top-notch system that will work for the remaining life of the car. The system provides the following components new:
OK, enough babbling, on to the install! (IMG:style_emoticons/default/chowtime.gif) |

my question was aimed at displacement. max rpm would be a factor. I was thinking about a 95mm x 80mm and keep the rpm below 6000.
wouldnt a MAF (instead of MAP) overcome the vacuum signature issue? |

I know you know this Sean but for others reading the thread the problem is getting rid of pulsations caused by the 4 different intake runners by using a common plenum and the low vacuum caused by performance cams. I think you're right Sean, a MAF would be an answer but I can't use one with SDS and I don't know if you can with Mega and Microsquirt. With SDS the common solution is to operate with TPS or throttle position sensor as your fuel control. This is no better than carbs when it comes to altitude as you have to retune for altitude changes. Sorry for the hijack. Your Microsquirt system will work. Mark has used it before...
