| Post subject: | Microsquirt - thoughts/opinions/experiences? |
Dear Slant 6 sages, I am contemplating running Microsquirt on a new/upgraded EFI system on one of my cars. This little bugger appears to have about everything I would need for a "non-all-out" EFI system. I would be upgrading from 2003-vintage MS-I ECU and will run port EFI and likely coil pack (wasted spark) ignition. I have MS3X (more functionality) running on the Project V Valiant, but feel that the Microsquirt would likely do everything I want at a fraction of the price ($400 vs. $800-1600 for MS3 or MS Pro). It seems you also need an external MAP sensor for Microsquirt, which is about $100. I am wondering if any of you are running Microsquirt. What are your experiences and/or how do you feel about it? Anyone contemplating using Microsquirt and have thoughts? Thanks! Lou |

I have a Microsquirt, but I am not running it yet. Mine has the modification to run LS coils in wasted spark mode. I feel it needs a couple of extra outputs to control stuff. I am surprised that DiyAutoTune hasn't come out with an expansion box to connect to the CAN bus. (Matt, hint... hint... hint...) |

Thanks, Kesteb. One of the extra outputs can be used to do 3 ign outputs for wasted spark. Seems sensible to me. Only thing you miss is sequential (separate inj outputs), but that does not seem like a big loss to me. Lou |

It also won't run the IAC sensor for GM based throttle bodies. But there is a box that you can wire in to do so. Except you loose those extra outputs to run the LS coils. |

I have never hooked up IAC on any of my stuff, so that would not be a big loss. Lou |

The MicroSquirt has been my go-to recommendation for someone who wants a basic MegaSquirt for a while. At this point, the only reasons I'd recommend a regular MS2 are (1) really wanting to build a kit, (2) needing stepper IAC or peak and hold injector control, or (3) wanting an easy upgrade path to MS3 later. |

Great, thanks Matt! That is very helpful from someone as knowledgeable and experienced as you. At some point I will probably upgrade my MS1 on the turbo (torqstorm pending) 68 Dart to Microsquirt. Best wishes, Lou |
