When my tunerstudio shows the ecu is live my dashboard gauges work and everything seems fine.. harness doesn't get hot just the ecu.. and it has good grounds and high 12 volts every time.. think I'll take you up on your offer aknovaman.. need to figure it out asap..

I'm interested in buying the EFI Source modified Micro to run spark-only on a carbureted LS1. Does anyone know if this will work alright? I'll only be using the factory crank and cam sensors, as well as a basic MAP sensor... Factory-style LS coils. No TPS, IAT, injectors, etc.
We were running the MSD 6010 box with factory coils, but it's a piece of ****. It can't seem to keep up with the power this engine makes on nitrous.

That would kind of suck. I actually think there's kits out there to set up TPS on a carburetor, so who knows.
I don't need anything advanced. Just a basic timing curve based off of RPM, nitrous retard, and a 2-step...Both of which I'd like to activate via WOT/push-button switches.

Been there...
You don't need the tps, or the iat, hooked up for the Microsquirt to control timing, they are used mainly in the fueling calculations, the iat can be used in some of the timing calcs, but you could zero those out in the tables easily.
BUT...
An IAT is pretty easy to hook up, so you may want to use it. And even if you only use the IAT sensor to measure the ambient air temps,changes in timing could help with some extreme hot/cold starting conditions.(street car only problem)
If you go to the extra work to hook up the tps, even just to report WOT(tps hooked to a WOT switch, like some BMWs are from the factory), you could use the squirt to control some of the nitrous stuff.
But for just timing control,and none of the "extras" you don't need tps or iat hooked up.
And just a note, you don't need the cam sensor hooked up either, not with a Microsquirt setup.

Boost Solenoid w/ Micro has anybody done it - if so how????
I was looking at this one from DYI and was hoping it only needs a output from the microsquirt.

you can run it off fidle not sure if you still need to wire it this way http://www.msextra.com/doc/ms2extra/...ware.htm#boost or if its different with the 3.5.7 micro

I called EFI Source and Mike said the Microsquirt V3 that's modified for a LSX motor car run the boost controller off fidle. fidle on one side and 12v on the other.
