I have a component built for the express PCB program, and its been verified, if anyone is interested.

Is this project still going to happen? It's been quite awhile since the last post and I haven't seen any boards for sale. Just curious!

After my initial panic at seeing 12v on the Vref, i looked at the DB37 pins i used for ground per the V3 schem. While they are grounded on the V3 board they don't appear to be grounded on the jim-stim...

So, now what I need to do is figure out what those pins do connect to, It makes no sense that ...

Ok, possibly not so bad afterall.

I ran just a 12v to pin 1 and a ground to pin 35, tested Vref and it was 4.9v.

I then was able to load code( 3.0.3t), and get it talking to TS. I was seeing CLT and IAT, no TPS cause the Vref was still dissconnected.

Though I am seeing RMP, the injector LEDs ...

Dang it, just realised this is not in the forum thread i wanted it in, i meant to post it in the module thread, not the general info. Don't know if it makes much of a differance, but i don't want to double post, so if a moderator wants to move it to a more apropriate thread that would be sweet ...

Ok, today marks my first really bad day in years of MSing :cry:

I just got a micro module from DIY-EFI for use on my bike.

The bike has already been wired to a DB37 pin connector for use with a V3 board, but the board was simply too large to be usefull.
So since I was planning on using the map ...

well, My 2cents....

double and tripple check your tach settings, these are SUPER important when being aplied to a low CYL. count engine. I have just started a 2cyl motorcycle install, and getting tach input criteria set correctly makes all the difference.

if you have a lab scope it will help a ...

I think ( if I remember correctly ) what you are seeing is normal, the DC2 applies to the second fuel table ( when dual table is enabled ). If you are only running in single table mode, DC1 applies to both injectors.

OK, so that did it, pins 1 and 2 and 3 an4 4 of the NAND gate still need to be shorted together, not pin 4 to 1 as the instructions stated.

Now I get to start tuning fuel....... alpha n, blended......AE, now the real wok begins. Thanks!

1. Don't lift pin #1 off the NAND gate.
2. Lift pin #4 off the board, and jumper it to pin 1 with a wire so that the PWM1 pin is output to both pins 1 and 4.
3. Use the former pin #4 pad for the 2nd ignition channel as above.

This is what I did, set up for 1 tach input. but the option for two ...
