Anyone running the megasquirt yet?
I have heard of some sand rails running the megasquirt on their n/a subaru motors, but has anyone heard of anyone running it on here that could chime in tell us what we need to run?

This guy did. I am close. I am trying to get the O scope of crank/cam, crank/coil 1 and cam/coil 1 so the code can be fixed. Though I might just do the same damn thing he is doing. Grind some teeth off and run as is. http://www.msextra.com/viewtopic.php?p=162390#162390 If I had the code I could have my car running this inside of a week. Sooner if I had all the parts right now. |

any luck with this?
we do many custom MegaSquirt installs and tunes. We haven't done any subarus yet, but we'd like to see it happen for someone. We have done V12 BMW engines in Land Rovers, V8's in Toyotas, and lots of custom setups. |

I have heard of many probs with the cam and crank sensors. Something about megasquirt not being able to pick up the signals from those sensors.
Other wise I heard its decent other than finding someone to tune it. |

I've been using megasquirts on subarus for over two years. These are all sand rail motors. They work great! I've done 2 liter jdm motors on pump gas @ 8psi, and race gas @ 20 psi. Also several 2.5 jdm' on race gas @8psi. I just finished my second one for a ez30r. Yes the vvl works, and the avcs works fine in open loop mode. All in all, I've done around 20 or just on subarus. I've also used them on twin turbo 4 liter v8 toyota motors, honda turboed 3.5's , turbo yamaha rhinos, turbo vw's, ecotecs, and a few more that I'm sure I forgot.
There is firmware in beta testing right now that will decode the 36-2-2-2 pattern on later models, For earlier jdm motors, the easiest way is to mod the trigger by cutting off all but two teeth , and welding one back on in a new location. |

I just found out the other week that MS2 extra code can do 6/7 wheels. The only thing is MS2 extra doesnt do WI yet.

MS will do water injection. You just need to make use of some of the spare outputs. Look in the Megamanual for the description of the board layout you're using.
More is available if you use the vastly better v3 PCB with MS2. Essentially, MS has a fixed number of outputs available, many of which can be mapped against MAP, RPM and TPS. You engineer your installation such that you have spare outputs for the extras. For instance, if you're driving coil packs you may choose to run wasted spark to save two outputs that you'll then use for WI. Part of the learning curve with MS is due to its flexibility. Many EMSs have a fixed feature set with no scope for DIY modding. The fixed feature set makes it easier to understand. The extensibility and configurability of MS makes it a bit of a brain-ache at first! |

You can turn it on using a output yes. Is it the same as WI on MS1Extra code no. The code in MS1 pulses the solenoid at the same time the number 2 channel fires. So if you use a RR regulator and the correct sized jet you will get the perfect ratio of fuel to water injected everytime across the rpm band. That is the difference.

I'm not aware of anyone who i using the decoder in MS2/extra yet. Which sucks, because the coders are looking for feed back, and I'm daily driving my 6/7 car right now. With nothing else to drive.

6/7 testing
Well, it may be a couple of months before we have any truly valuable feedback, but my friend and I are currently in the process of designing and building MSII Extra ECUs for two seperate cars. One is a 90 Legacy 2.2L that he is turbocharging. The other is my own baby/project, which is a Plug-&-Play ECU to drop into my 98 Legacy GT. I know the 98 uses a 6/7 wheel, but I still need to do a little research on the '90. If anybody knows what the N/A 2.2 from a '90 Legacy uses for crank and cam wheels, I'd be much obliged if they could pass that information on to me.

Should be the 6/7 as well. Pretty easy to check though.

i was saving up to experiment with MS on my e30 but then it got hit. I'm really interested if anyone has successfully done it

If they have then nobody is talking.
I really wish I could do this on mine, but alas I have to drive it to work everyday and can't have it down for any time. |

Sure you can. You can make a plug and play kit with there designer kit. Thats what I am doing. You just have to be sure of what you are cutting and that you crimp correctly. Yes I can say for a fact that a 90 legacy uses 6/7 setup. Everything does til 99. When the turbo motors went phase 2. So all the phase 2 turbo motors are the 36-2-2-2 setup which is supported if you get stuck with the 6/7 setup. |

That kit is crap. I'd rather make a real PNP out of a stock connector, if I was going to go that route. |

Stock connector
I've actually been looking for stock connectors as an alternative to using an old ECU. Do you have any idea where I would find these connectors? I have the 96-pin connector found in the 98 Legacy GT, as well as the 98 Impreza 2.5 Coupe.

I have been talking to justin at DIY about my set-up. I am hoping to use one of your crank wheels. To my knowledge I think that'll be all i need to get my car running on it.

That would be me, and yes our crank trigger wheel with a sensor would let you use the MS1 with no problem. |

It appears that the 96-97-98 all used the same ECU connector. Colors are pretty much the same as well. That should open up the search for anyone looking to make a custom harness. I have a cut-off connector from a 98RS harness, along with a few ECU's. I'm keeping them though!
MSII is something I very well may do here in the short term. Jay Storm |
