Noise issue is fixed and the thing still will not run. I am running ms2 extra 3.1.0. It cranks, runs for almost 2 seconds and dies. I can not catch it with the throttle.
Injectors were serviced and fuel pressure verified. New plugs, cap, rotor and timing has not changed since it was running before injector service and firmware update.

My log file is at:

Any ideas?

You're making it hard to help. Starting a new thread means people reading this won't have the background of your prior posts. Please stick with one thread for one problem.

You still haven't posted your msq. It's pretty likely your settings are screwed up, but it's impossible to tell without the msq. I can tell you that your VE and pulse width at idle is significantly lower than mine, and your symptoms are consistent with not enough fuel. You also don't seem to have any after-start enrichment, and probably not enough warmup enrichment.

Tell us about your engine. Must be a 12A since you seem to have a distributor. What injectors? What injector arrangement? Two injectors on bank one and two on bank two? I see pulse width on both banks during cranking and idle - that seems wrong.

I do not have access to my computer today. I will try to give you guys as much info as I can. The engine is how I received it other than the ms. I am running fuel only with ms2 extra 3.1.0

J-Spec 12a turbo with OEM Hitachi Impact turbo and Saab style intercooler. I have a TWM throttle body on a RB tri-y intake with 2 720s @ primary and 2 780s @ secondary.

The VE table is straight from the aaroncake.com walkthrough. ASE is tuned off per his recommendation as well. WUE has been used at different settings, I believe the log file is using his WUE settings as well.

The injectors are not staged because I did not find that option in Tuner Studio.

The car was running and I was tuning when I watched the it lean out and shut off while idling. After pulling the injectors, I found all 4 clogged with goo caked on top of the injectors. PWs at idle were 1.6ms and very smooth around 1200rpm

I will try to upload the .msq file after the parade in the morning.

Thanks,

I'm assuming you have your two primary injectors wired to bank 1 and the two secondaries wired to bank 2. In order to use staged injection, I believe you have to change "Specific bank 2 setting" to "Off". Otherwise you're using all four injectors at idle, which would make it very difficult to keep stable.

Did you intend to enable dual table? I've never paid attention to how that works, but I don't think you've got it set properly.

Are you sure you can't do staged injection with fuel only? If you change the user level to Advanced, the other menus (including staged injection) are active.

I don't understand why turning off after start enrichment would be good advice. I think it would be very difficult to keep a cold engine running without it. Looks like you've got warmup enrichment turned off for your starting temperature, too.

Apparently you don't have an idle valve. Do you have the throttle adjusted so it gets enough air to run when cold?

That's all I've got for now.

I now have the injectors staged per the aaroncake recommended setup. Adjusted fuel pressure down to 43.5 from 45, added ASE and WUE. I intend on using single table setup per Ken's suggestion. Throttle stop is adjusted for about 1000 rpm currently. New log and .msq @:

If we can believe your WBO2, you're going lean. Have you tried more fuel? Or, sometimes the sensor can indicate lean when it's very rich - have you tried less fuel? Have you confirmed your ignition timing?

I don't have any experience with low impedance injectors. Do you know that your injector PWM settings are correct?

And the starter has given up. I pulled the thing apart, lubed the shaft, made sure everything moved freely, and no good. It just spins freely. Guess this thing will have to wait until after vacation.

Out of context it is bad advice. In context with the first startup on an already overly rich table where the tuner is just trying to keep the car alive while the ECU is dumping in fuel, it makes complete sense.
