You may not of read but this ECU has worked (quite well at that) on this motor before (non-build though). So I know it can handle the alternator.
By external field input you mean the 2 wire plug on the alt?

Yupp. It comes from contact 1O on the 22 pin connector. Color is grey/red. If that doesn't read any voltage, your alternator won't do anything. Not sure what the voltage should be. Joe Perez is one of the people who know this stuff. Search his old threads if you need the voltage.

Still Oscillating
Thanks to the lovely support of DIYautotune, I received a new(ish) MS2pnp today. Put it in place of my old one, loaded my tune, double checked some things, and installed my GM IAT sensor.
Fired her up.
Holy **** it's charging the battery now, and seems to be controlling my IAC valve too. I had it set to inverted idled and died/ set it to normal cranked up and the RPM's just kept raising. So I know it works now.
I'm still having my oscillating idle and AFR problem though.
Does anyone know anyone in the Tampa area that'll do wiring? I want my inputs and AFR gauge wiring redone. (As I'm doubting what I did)
I finally have time to work on the car though, hopefully everything will be good to be good to go by OCT12 for FL2K13. Probably not though.
I also had to change my ignition setting to single wheel missing tooth and not duel wheel missing tooth for it to idle and not die.
Attached is the final tune and datalogs.
Since I have time now, I'm thinking of removing the ID1000's and putting the stock MSM injectors back in. Correct troubleshooting path?

So, I swapped the stock injectors and disconnected the vtcs vacuum line. I got it to actually idle last night. it wasn't too bad, a little high. it also was hitting a second limiter/ launch control type thing at around 4500-5000 for a split second of popping ( but AFRS looking good)
then would climb like normal but I would let off the accelerator by this time as I was scared.
I go to start it today.
Starts and dies, starts and dies, abd fir the life of me I couldn't figure it why. I had a mini panic/ stress attack si here I am drinking run/ coke posing about it.
$8k buy the car.
or I need someone to give it to that knows what's they are doing.
I had my ID1000s tested today by Boost Labs, they are perfect, they actually said they are the closest pair they've seen cone in. So the injectors are great.
I talked to them about the EFR 7163 too
, he said he can get it before full race does. I all have to talk to south east power (matt) it's a mostly diesel shop , they are a distributor fir Borg Warner and I've had many recommendations to talk to him.

Yes sir, awhile back but I did. With the missing tooth setup is really hard to have timing off.
I originally had it set missing tooth at 80° w/ fixed timing @ 10° but the light showed TDC. changed missing tooth to 70° light showed 10°. Haven't touched it since ( bruising going from fixed to table)

This may sound silly, but, where is your vacuum pickup for your MAP sensor?
If it is close to the TB, laminar flow will cause very erratic MAP readings, and pretty much everything will be unstable. You need to use the nipple at the far end of the manifold.
Also, have you tried setting your idle with the IAC unplugged? (IAC defaults to "closed" if it is unplugged). You need to to that with a warm engine.

Sixshooter came by today to try and help out. No progress on idle problem but he asked me to upload my tune file and the datalog we did.

So I looked at my old logs from almost a year ago when the car actually ran and I noticed something. But I can't seem to figure out what it is or what it's for.
-Render Non Interrupt Data- option in MLV..
Before when car was running:
(rendering option enabled or disabled it shows the same)
Now:
Disabled
Enabled
Could anyone shed some light on this option?
