Good write-up!! It's cool to watch you get it together.
It appears that your MAP is calibrated to "0" with the engine off. . . It should be calibrated to read "100 kpa" with the engine off. 100kpa is atmospheric @ sea level. Your engine vacuum idling will pull you down to around 40-50kpa depending on the cam and overlap you're running. Re-check that or you will not get it started later. |

Ahhh, you are about where I was last month now. For the connection, make sure that the ECU is getting good voltage. You may need to put a charge on your battery. On your laptop get the port check utility and run it. It should detect the ECU and ping back which firmware its running. MAKE SURE THE BOOTLOADER WIRE IS NOT GROUNDING SOMEWHERE! If its grounding somehow the ECU will act as if it has no firmware. Wish you were closer - we could support each other. lol! Zach Zach, thanks for the tips. I think I might be able to work on it tonight. (my car is at my parents place and I live 1 hour away!) Hows your car coming along? |

Glad to see the progress Pete!
This sort of thing is exactly what defines the 'learning curve' of MS. It's a pain in the ass and it can feel like you can never get through it, but Once you come out the other side, you'll know much more about how all this works. I just realized how perpetually true this is - I just finished beating my head against the wall for three days straight on weird MS problem. When I finally found the solution and everything went back to normal, it was a major celebration. These problems can feel like you have no idea what to try next. But it's all worth it in th end. |

I have not touched it since Herb came over. I let temptation in the door and started shooting and kayaking. :-)
Summer needs summer hobbies too. Besides, its been too stinking hot and humid to futz with my car lately. When I get back from New York next weekend, I'll start working on it again. Literally every time I work on it now I think its going to start running. So far I've been wrong every time, but it does get closer each session. Zach |

I got a little further along last night too. It turns out my Dell computer has been known to have a finicky serial port. I had bought a usb to serial port and it arrived yesterday by chance so I attempted to upload the firmware to the ECU. Success! it loaded perfectly. But after I connected with tunerstudio it wouldnt let me burn settings to the ECU again. it gave me the error "Burn page failed CRC Check" I have a feeling that it is still the firmware. I need to get a copy of the firmware that is known to work.
HInt Hint, Mark. You got a copy for me? |

If you suspect firmware, follow the links in my thread to the BG 3.83a code and the firmware loader. But if you can connect to the unit, I don't think it's firmware. I think you just have a bad setting, that may drive you nuts.

One thing that I have found that will cause nothing but problems (and many intermittent problems), is GROUNDS.
Many folks make harnesses that have individual sensors grounded locally at, or near, the sensor. This is convenient, but it often promotes intermittent grounding issues that cause you to chase your tail and bang your head in frustration. Been there; done that and didn't like it!! For this reason, I add a simple terminal block and have ALL grounds go to a single point. Then I use primary wire and tie it directly to the battery's negative post. This eliminates poor grounding issues permanently. I also do the same for all power connections for the EFI system whether it be "12V+" or "switched 12V+". This absolutely simplifies things. Just something I've been doing and have had great success with, FWIW. . . |

It's especially helpful on the ground side as it essentially eliminates the possibility of ground loops. |

All sensor grounds go to the ECU. All non-sensor grounds, including ECU, go to a single ground point.

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. |

Following this one Pete.. Can't wait to hear it fire up.. Those intakes look a heck of a lot cleaner than I remember them !

I have resorted to connecting with a desktop computer. Its the most reliable connection I seem to be able to get. As far as other progress, not too much.
I am still having trouble with testing the coils and the injectors. I have been trying to tap into the wealth of knowledge on the megasquirt forums, and some seem to think that I am getting some sort of high voltage from the coil thats getting back into the Microsquirt. I double and triple checked and all four coils are grounded properly. All my settings in tunerstudio are consistent with what is required. Im out of ideas. |

A few more months, and I'll just take a nice drive out your way to lend a hand. (IMG:style_emoticons/default/wink.gif)
