Made a stackable version, with all the normal io and ad lines on arduino shield´s (uno) stil usable
the board is 58*100mm
11* power outputs
4* ignition outputs PNP (TC4427CPA)
6* analog inputs
cas , lm1815 or opto
cam, opto
the first board is for hellfire WBO2 code (atmega328)

ares/cadcam files for the stackable pcb

Awesome to see you back again turtana!

I'll be interested to see how you go with the Hellfire. I've heard bits here and there about them, but nothing conclusive about how well they're working.

You can share the files to make my own?

it has taken a while, test driving next week no mater what

[turtana]

Finaly i got the hc-05 BT adapter to work, first proto finished, only one flaw on the pcb.
the error is on the one ignition output and is fixable with a solder bridge.

It´s good to see that DIY-EFI community thrives. I´ve been in megasquirt-scene since 2005 and I think that it just lost its glory Nice to see some old nick´s from FINSQUIRT-forum

well the first test drive went well ass expected

i think i have some issues from the injector drive noise affecting my lm1815, fixed it by using 22k input resistor and pin5/3 mode (connected to vss)

5 uF of capacitor to the ignition coil vss line and it cured 70% of the noise seen with the fluke scope.

i still like the lm1815 even if is a litle old and crude thing.

thaks Vauhtivaunu, i like the speeduino to be better than mega just for the simplicity of it. it just works.

making second proto, with the minimum components. need to make few changes.

cutted the "reset-en" pad from mega board and no more 3x reset problem when connecting to usb, car stals when ecu connects when the reset pin ins connected.

This is work?
