Jeff,
I bought the thing a while back to put on wife's 924 turbo when I rebuid it. It's interesting you mention using it on turbos.
I got an old no start 944 for to fix up for driving while 924t is down. The 944 came with 2 computers. Neither one cranked it up after checking all the sensors, fixing cracked hoses under intake, etc. Bought another computer & no luck so I put on the TEC II.
It was kind of rough figuring how to wire into existing harness. Had to think about & fabricate mount for pickup & slotted timing wheel. Had to find a TPS sensor not switch, & make an adapter to mount it.
Problems starting: Commo error on my laptop, was due to having TPS wired wrong. Still had a commo error, but was able to drag big computer out & got commo & programmed it so it fired up with ether. After plugging fuel pump relay in & new gas, it fires & quits after 5 sec. I think I programmed for to big an injector. I'm trying to find out the flowrate for stock 944 injector & come up with some kind of serial port buffer for the laptop.
Only thing I've seen wrong with Electromotive's manual is size for sensors. I had tapped out the block for knock sensor according to manual & had to get a bushing since I tapped it too big.
The way a TEC II can improve an na is getting rid of that flap thing that measures air, let you put in a big cam, throttle body, & freer exhaust & adjust timing & fuel for the mods.
