I was wondering how many of you are running a megasquirt II in your fiero and how you like it. is it responsive and give you all you need for control to make you car run the way you want it to run?

For as cheap as they are and the significant increase in capabilities over even a modern GM ECM it's a heck of a deal.

I am leaning towards the II as it covers all engine management operations . heck adding the relay board it can control everything for the engine including the fuel pump, fans, even a boost controller in boosted applications.

any comments or ideas?

doesnt it burn everything out faster???

I did allot of research on MS before deciding on the 7730. I'm not aware of any significant increase in capabilities over modern ECM's. What I did like was the ability to tune it with easy to use software without the need to buy a dedicated chip burner and tuning software. In this regard the price becomes about equal. What did you find better about the MS?

I use it to run my ecotec, works sweet! You need a WB-02 and a knock sensor for sure tho. W/O those 2 things you will break an engine, I did . And wihtout a WB you cant do much.

are megasquirt knock sensors as accurate as a stock GM sensor setup would be? Can you read miss fires?

It looks like the MS-II has way more processing power as well as bigger tables to work with. The biggest thing I'm looking at is the CAN bus support so adding a 4t60E actually becomes an option by getting the tranny and the tranny's control box, reading their forums it sounds like some are having success with interfacing to some of the canbus modules in the newer cars.

also it's set up out of the box for boost up to 20PSI ready for knock, etc... Granted the 7730 can be as well, but I am having aa devil of a time finding a 7730 with a $88 prom and memcal at a reasonable price, so I have been looking at other options. It looks like they even give you a base 2 bar maps to start with.

I hate that it's still a batch fire on the injectors though. why cant they give you 6 injector fire lines so that you can have each injector fire when needed instead of firing and leaving a puddle in the intake every other stroke.

From what I read the MS knock sensor is a GM knock sensor.

VEMS (http://www.vems.hu) offers sequential injection for up to 8 cylinder vehicles, and can even handle coil on plug (non-wasted spark) ignition. It's EGT, wideband, and knock sensor ready as well. That said, the website pretty much admits that it isn't as user-friendly as megasquirt yet.

An aftermarket computer that isn't struggling to function as well as a 15-year-old obd1 box makes me drool.
