I have remained extremely lazy up until now but I figured I'd get the cams set and engine buttoned up tonight....then realized I pulled the timing cover with the engine at #1 exhaust not TDC, so I had to pull the cams and spin them 180 degrees. Then I couldn't get the the last timing chain sprocket on, a loop hiding somewhere in the chain, so cam back out so I could spin the engine safely, cams back in and sprockets on, ready for me time actually time the cams tomorrow. The goal is to have the engine at least sitting back in the car this weekend.
I'm told the ECU board design is final and we are now waiting for a few components with the first batch expected the end of march or early april. My BMW ITB throttle actuator uses more power then normal ECU outputs handle so board guy is making me an external driver that is supposed to be plug and play and will also be sending me the ECU harness connector so I can get busy wiring it in. I am responsible to write a user manual, I'm about 2/3 through documenting what I see in the software and confirming how it works which should make the switchover pretty straight forward.....should.
We're using a chinese version of a 154pin bosch case/connector so it will at least look like a real ECU. The final pinout has 35 analog inputs (7 are temperature capable), 18 fuel capable outputs and 12 spark capable outputs, , another 20 generic lowside outputs, 4 highside, a couple 1/2 bridges 8 hall sensor and 2 VR sensor intputs, 2 CAN channels, pretty fast USB, internal SD card logging, accelerometer, 8 thermocouple inputs....I got most everything on the wish list I think. Hopefully its everything I hope it will be.
