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) |

The day after Rich got the EFI operating correctly, a couple weeks ago, his wife had their first baby. As Chris said... Jeffrey Linus Wilner born 1/25 @ 4:32 pm. Everyone's happy and healthy. He has a really strong grip already...maybe strong enough for a torque wrench? He here is passed out after I gave him a lecture on port injection vs. direct injection: (IMG:https://lh3.googleusercontent.com/-uE7qRMZfHLo/TzJ28isySBI/AAAAAAAABFA/XquF6q4dFco/s800/photo%205.JPG) Back to our regularly scheduled programming! Here's a picture of the oxygen sensor and oxygen sensor brain mounting. The brain --> ECU cable is routed down to the clutch cable wheel plate -- it looks like it's touching the heat exchanger in the photo, but it clears just fine. The brain is secured to one of the transmission mount bolts using a reformed P clamp. I used a longer bolt in this location to receive the second nut. (IMG:https://lh3.googleusercontent.com/-VUHqt_uAmRk/TzJ28pCaOmI/AAAAAAAABE8/nJKTu01eGZ0/s800/photo%201.JPG) (IMG:https://lh4.googleusercontent.com/-fI-7NNh5yMY/TzJ28i4rYpI/AAAAAAAABFM/-kSisiOfMkY/s800/photo%202.JPG) I am very happy to report that the car is running 100% on all 4 cylinders -- I'm using it now for (seemingly daily) diaper runs. For a long time I was having an issue where the car was running great on cylinders 1 and 3, but ran like crap once I plugged in 2 and 4. Many hours of troubleshooting later, we discovered that there is a parameter in the software called "offset / advance for output #2" that I had set to 180 degrees...well...the system automatically advanced output #2 180 degrees based on the configuration (4 cyl / even fire / wasted spark), so I was actually advancing the second output 360 degrees by setting that parameter to 180. Not good. After I set that parameter to 0, the car ran like a champ. Tonight I'll post up my .msq file so that any others planning a mega/microsquirt conversion can use it as a starting point. Anyone purchasing McMark's setup should be able to use this as a turn-key file to get their car started, running, and driving. You will definitely have to make tuning adjustments for your motor no matter what you're running, although if you have a stock GA 2.0L, this file should be 80% or better to a final tune. Note: I developed this tuning file using the V2 microsquirt enclosure. DIYEFI is now selling the V3 enclosure which has a slightly different pinout and form factor; however, I have tested this file with the V3 enclosure and it works great. I'd actually recommend the V2 enclosure over the V3 if you can find one because the V2 enclosure is extruded aluminum and the V3 is molded plastic. I still have some final bugs to work out (tach not working with the MS output, O2 reading is a bit wacky, oil temp gauge not reading, need to replace ignition switch), but the car starts right up and drives awesome.
