I found so much usefull information about Megasquirt/Microsquirt here, so first I would like to take the opportinity to say thanks to everybody who posted informtion about MS here before as it all provided good guidance to me when I was planning my own project.
My motivation:
I'm running a 9590 camed 2056, which pulls strong but not as good as expected. Problem is, that cruise speeds here could be much higher as the once you are used to in the US and if I eliminate the lean spot above 4000 RPM cruising, I'm running too rich in cold start conditions and also overrun conditions are too rich.
I still wanted to keep the stock look of the engine bay, so I will keep the distributor and integrate the MS2V3 board into the original D-Jet housing and use the original relayboard to power the MS and the Fuel Pump.
MS set-up:
TPS based accelaration enrichment
ATM correction (second MAP Sensor on PCB)
EGO Sensor: Spartan II
Ignition: Single coil with fixed distributor and BIP373
Idle Valve: Curently none, using only original CSV, will add stepper type idle valve later (my own design, also stealth type)
Oil temp sensor
Bluetooth communication
Sensors (modified original MAT Sensor, TPS Sensor, BMW CHT Sensor):

Engine is running, idle is perfect, cold start behaviour is good, just need to get out to drive and tune the fuel tables before I go to a dyno shop for adjusting the ignition table.
I'm very happy with the installation and as you learn while you work on the project, everything went really well.
There is also perfect support on the Megasquirt forums.
The only thing I really struggled with was EMI problems caused by the ignition system, after upgrading to Magnecor spark wires that problem was solved.
Cheers and stay safe,
Frank
