Brain fart regulator question Options

[mb911]

So was noticing I have less voltage while the car is running. I am use to seeing 13/14 volts as the pretty much normal. I have a fairly new marchel alternator and this year I am seeing 13v on the high side. Now I do have more electrical items, wide band o2, mega squirt, and active exhaust. Regulator going bad? Pictured in upper left. Hmm maybe I have them on the wrong pins? Might have messed that up?

Not sure if this will help...

The late model Miatas have a generator and the voltage regulator is the ECU.

Megasquirts can be arranged to provide this. You end up setting a "target voltage" in parameters in the squirt.

Don't know if this is applicable to a Porsche generator but the hard work may have already been done.

If you want to try it look to the Mazda solution for directions/ideas.

"Late" Miatas mean NB1s and NB2s for me. So, the years I'm referring to are 99-05.

I think some of the NAs pre 99 also did this as one of the old school mods to make this work was installing a 90-93 alternator in the newer model.

After they figured out how to work it in the squirt no one puts the old alternator in anymore.

Hmm that’s interesting and good to know. I am learning MS right now. It is an amazing ECU for the money
