I had my car on the road for only two summers until I wanted to get a more reliable engine. I was not too familiar with the microsquirt, or megasquirt system, but when Mark started to offer a kit I knew that it would be a great starting point. I also had followed the progress of McMarks, rwilner and Zachs conversions and figured they had done enough trail blazing that it would be a piece of cake.
I started to piece together my own little manuel of pictures and notes from other threads and came up with my own little DIY powerpoint. So hopefully this thread can benefit others and hopefully these guys dont mind that I am reposting some of their photos. I didnt just decide to buy the system on a whim though. It all started one night when I was driving home on the highway and I heard a pretty large bang. I had just replaced my oil pressure relief valve with the new tangerine product and thought my engine had just exploded! I pulled over and realized after digging around that my #3 spark plug blew out of the threads. I have a head temp sensor under the plug, so Im thinking that it wasnt turned in all the way and the pressure was too great for the threads to hold the plug. BTW the pressure relief valve is a great product That winter I pulled the engine and then the head and put a time-sert in #3 After bolting the heads back up, I noticed that my valve train geometry was off. So at that point I decided to measure and cut custom pushrods for the proper geometry. https://www.youtube.com/watch?v=aE-TJxlE7Ck And since I had the engine out, and Chris had just come out with another great engine product, I figured what the Hell, and bought his SS pushrod tubes and installed them. At this point I had been thinking about McMarks EFI kit seriously, and decided to pull the trigger. I ordered the kit from Mark @ Original Customs. I patiently waited and my kit finally came! Im using the stock 2L plenums and throttle body. Here is what came in the kit. (photos from Zach) I got the same stuff. |

With the help of two buddies, I was able to put in a couple hours of work into the microsquirt EFI today. We were having difficulties with figuring out the actual problem, and found someone else on the forum having the same issue. Phil Tobin suggested just to load the MS2 Extra 3.3.3 firmware and it should solve the problem. So we loaded this onto the ECU and we were back to business. We were able to connect to the ECU and we even calibrated a few sensors and burned info to the ECU. Until we lost the connection with the ECU again. I suspect that it is the computer that is causing a lot of these connection problems.
I will be loading Tuner Studio onto my MAC and getting the driver for the usb to serial port. Hopefully I will be able to resume where we left off. |

Been trying to avoid posting here as it is fun to watch everyone else help out. Seems the community has finally turned a corner with Megasquirt and people are finally getting on board.
2 quick points. 1. The Extra firmware is better in so many regards, I always just start there. 2. Are you using a USB->serial converter?? Most are finicky as hell and all in different ways. The only one I have had any luck getting long term reliable connections with is the one DIYautotune sells. One little connection hiccup in the middle of a memory write will really ruin your day so best to do whatever you can to avoid them.

I am using a USB-> serial port, and it is the one from DIYautotune. I will try with the MAC to see if I have any other results, and if I still get connection problems I will have to find another computer. I thing I have one more computer at work with a serial port connection. |
