Miata engine management system

[Greg Amy]

ANYTHING is possible, Chris. I don't know anything about the Electromotive system, buts bits is bits, and programming is programming.

Personally I'd buy a MegaSquirt and be done with it. But if you've got The Big Love for Electromotive, "if there's a will..."

I thought DIYautotune.com had put together a plug and play package for the Miata already, based on megasquirt.

Yes DIYautotune has a P-n-P for Miatas. The price is very fair and Megasquirt is a pretty decent system. MUCH easier to work with than an AEM and it uses the same basic tuning algorithms as Electromotive (VE tables).

ISC Racing in Florida also has a PnP ECU, though I don't know anythgin about tunig it other than it uses a "smart card". It is very small.

There's a lot of guys who have figgured out how to hook up a motec without removing the factory ECU case from the loop (old rules) in RX7s, so there's got to be a relatively easy way to hook them up, too.

can the Tec-GT be used with the factory ignition? BTW - the cam angle wheel in the OE distributor could be replaced with an Electromotive style 120-2-2 and the sensor either swapped or made to look like a sinusoidal output with the appropriate addition of Rs and Cs. don't know how well that would work, or if it is indeed worthwhile, but it is "possible".

We ran the Electromotive on our Production Spitfires for years with the 120 tooth wheel inside the distributor with no problems. Not as accurate as crank mounted unless you have some very new drive gears but it will work. I would call ISC as he has one wicked fast setup. Why invent the wheel?

Based on trying to follow, and failing, Kip and MIke in their ITS Miatas the last two years, I have to say: do as they do......

[Andy Bettencourt]

I am running the same system as Mike and Kip. We developed them independently of each other a couple years ago. It works well!

I think this is a case of someone trying to utilize something they have - or have access to for real short money.
