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) |

I started off by removing my motor. This was my first engine drop and I feel obligated to say "it wasn't as bad as I thought!"
Note that i used Racer Chris' engine plate which made this so easy a caveman could do it. I more or less followed McMark's procedure on this site, but had a few extra steps to contend with because of my aux oil cooler, cyl head temp sensor, amplifier and other items. Here's the car with no motor in it: (IMG:https://lh6.googleusercontent.com/-w91zZlbzXLU/ToJ8gfk2y2I/AAAAAAAAANw/L-JN9sHP19k/s800/car_engine%20removed.JPG) Here's the motor removed, with all the stock fuel injection installed: (IMG:https://lh4.googleusercontent.com/-laWTYayYW2Y/ToJ8mSyUNFI/AAAAAAAAAN8/dB0LCeDxNIw/s800/engine_old%20fi.JPG) Here's the motor stripped of fuel injection and induction: (IMG:https://lh3.googleusercontent.com/-Z7JiPK4Waw8/ToJ8g44Bq2I/AAAAAAAAAN4/UmEGsQEWtyY/s800/engine_fi%20removed%20%282%29.JPG) Here's the stock fuel injection wiring harness, computer, and components, ready to be retired. This stuff came off quickly and it felt good to be putting it out of service, like retiring a hall of fame pitcher that's past his prime or something. (IMG:https://lh6.googleusercontent.com/-VyFpcPghYbU/ToJ8urTZUiI/AAAAAAAAAPg/S0CI_LskCi0/s800/old%20FI%20computer.JPG) (IMG:https://lh6.googleusercontent.com/-si4iHmVasEo/ToJ8uRhOYYI/AAAAAAAAAOI/cvhrreo3FJo/s800/old%20FI%20removed_in%20box.JPG) Here's my car, patiently waiting for its smarter powerplant: (IMG:https://lh5.googleusercontent.com/-R2aaqGA-844/ToJ8veeF4xI/AAAAAAAAAOQ/n0soxwL8wYg/s800/patiently%20waiting.JPG) I'm correcting some items while I have the motor out, for example, I went to replace the throttle body gasket and couldn't....because when I took the TB off there was no gasket at all!! Lots of little things too, like missing fasteners in the engine tin and this flap missing from the impeller housing --> heater branch feed (that's Racer Chris' engine plate in the bottom of the pic): (IMG:https://lh4.googleusercontent.com/-l5T164Z2mLY/ToJ8oU4oVyI/AAAAAAAAAOE/YFpMjlj8vaw/s800/missing%20flap.JPG) Next I removed the fan shroud and installed the pickup wheel and pickup. I documented my fan shroud removal adventures in another recent thread. (IMG:https://lh4.googleusercontent.com/-LlaFAsuTTew/ToJ8gsjXrBI/AAAAAAAAAN0/z8oxTJBWC98/s800/engine_no%20case_trigger%20wheel.JPG) Here are some closeup detail shots of the trigger wheel and pickup, which show the gap (about 1mm) and angle. McMark supplied the special bracket which positions the pickup at that location. Note that this is 100% bolt-on -- no fabrication required. (IMG:https://lh3.googleusercontent.com/-H5p1EJxfYOw/ToJ83nhesVI/AAAAAAAAAOg/ZB5zW21UfBE/s800/trigger%20wheel%20close_no%20case.JPG) (IMG:https://lh4.googleusercontent.com/-3lTPjzHme_E/ToJ88DqZS5I/AAAAAAAAAOk/QJ-EFeP0ISc/s800/trigger%20wheel%20sensor%20pickup.JPG) (IMG:https://lh6.googleusercontent.com/-9mZpy-7HwOo/ToJ83knRdJI/AAAAAAAAAOc/tv46etuyruE/s800/trigger%20wheel%20pickup%20angle.JPG) (IMG:https://lh6.googleusercontent.com/-3jFRclo3ENg/ToJ8z-j0K5I/AAAAAAAAAOU/1OYz-fj7N7Y/s800/trigger%20wheel%20close.JPG) (IMG:https://lh4.googleusercontent.com/-KFBoIF0KU70/ToJ80yuOiOI/AAAAAAAAAOY/6c2y0GUBiGc/s800/trigger%20wheel%20case%20installed.JPG) Note that before the fan shroud goes back on, you need to connect the magnetic pickup to the wiring harness. I used a dremel to make a notch in the engine tin around the passenger side J tube, put in a grommet and ran the sensor cable through that. The pickup wire runs along the same basic path as the oil temp sensor wire. That's it for now, my goal is to have this on the road by the end of October... More pics to come as I make more progress! |
