First, let's get the injector outputs sorted. See this article for how to check them.

Everything checks out till i get to. If the signal is making it to Q1 or Q5, but the injector driver isn't working, first check for continuity from pin 2 of the FET to the DB37.
i dont know what a fet is i googed it and looked at parts list?
Thanks

Ok, it sounds like the circuit itself is working. What if you try injector test mode on the Stim?

Try reloading the firmware and starting with the default tune.

Maybe. It won't be a problem if you did.

So I show my lack of computer skills again. Took me well over an hour to to flash the firmware. Tried 2.92 it still showed 2 controllers when detecting. No ing lights on stim but it looked good on the three lights on the ecu. Using BG 2.92 example. I played around and started to configure a tune and set ecu to 1 for ms2. Every time I pulled power and repowered up the stim it would say controller configuration error and tunerstudio was 1 but controller was 2. No matter how many times I hit burn it wouldn't take. Flashed aging with 3.3.3 and still shows 2 controllers lights on ecu don't respond properly. Plugged in budys Jimstim fidle and pump log up but no Controll on tunerstudio. Had enough for one night.

Played with it again. Starting to get realy bummed out.

When detecting you should be coming up with 2 ECUs. The difference between them is the driver that it is using to communicate with the ECU. JSSC is the new driver and RXTX is the old one.

What are you changing to 1 that keeps going back to 2 and results in a configuration error?

If you load the wrong firmware (MS2 comes in 3 different hardware configurations each with their own firmware) the outputs won't work correctly, a MSQ or a screen shot of Tunerstudio while connected can help to make sure that isn't the issue.
