Wasted spark coil pack fired by factory ignitor
This is on a '98 RS 2.5L. I added the turbo/intercooler from a WRX 5 years ago and ran 6 psi of boost with the factory ECU. I had zero issues in those 45,000 miles.
I built a lower compression 2.5 to throw some boost at
I didn't want to hack up the factory wiring so I when at it via the ECU
I forgone the DB37 and wired directly to the MS board
Right before the transplant
It is somewhat anticlimactic since the exchange - it looks like it did before. But I went for guts not aesthetics.
I started it yesterday and it fired up Now on to tuning. I am using the ignitor to fire the coil pack and the STi crank gear (36-2-2-2).

I built a knock detection circuit and it is working. But it could be better.
I got the EGT working. I am using an AD595AQ Type K Thermocouple amplifier and was pretty basic to wire. It is really cool to be adding this functionality to my MS. Here is everything working together. I am feeling very confident about throwing on a larger turbo that is just sitting on my work bench.

Have you changed this tune since and did you dyno this to see what HP you are putting out?
How is the engine how many miles do you have on the engine since the computer was intalled?
Re: '98 Subaru - MSII, v3.0, fuel and spark
The tune can always be better so I have changed it a few times since I got it running good. I got about 5000 miles on the odometer since I added the MS. No dyno runs.
