Ahhh no problems then. For some reason I was testing the other day with your board selected and noticed that 2 of the injector pins in the main code clashed with the tach pins. Was causing all sorts of strange behaviour.

I'll update the main code to match that.

i think this is the "formal" pinout for my board now. maybe the pinout of my curent older protoboard messed up the pinout at some point.

So i had i litle downtime do to my laptop popping up it self.

i newer did draw a schematic to this board. the the circuitry is kept wery simple in the board.

2 speed inputs (crank/cam) LM1815 and a optocoupler
10 outputs on to220 mosfet (injector,fuelpump,idle,etc..) all pwm capable
standard a/d inputs iat,clt,tps,map internal,map external,aditional temp1,aditional temp2
4 ignition outputs, 5v PNP output with 100mA feed (depends on the feed resistor), configurable to use standard pulup resistor type output. (pnp out for VAG cop coils demand more than 40mA drive)

after the pover feed changes on the board, the proto seems wery stable. Atleast it revs to 9k with ease.

i will try and have a few board made. final dimensions are 10*12cm and it fit to the hammond 10*5*16 aluminium casing

changed the d37 connector for molex 24 pin and 10 pin 90" rotated pcb side connectors.

with the 24 pin connector you only have 5 outputs (max 10A) the other 5 come out of the secon 10 pin,s on the pcb. with a 6 pin connector you can have the 5 extra outputs to use.

edit.

so the board is finaly going to production next week.
the next board will have a arduino nano for multiplexin 6 cyl cop. ( yeah i use ES9 peugeot engines now) and the stepperdriver for idle.
the is still the question of the drive by death trothle control.

Here is my "reverse engineered" PCB. But all we will be happy to see a PCB with all the component values written.

Cool, you should try and convert it to a Fritzing type file so a schematic can be seen as well.
