OK so i ran all my wires the way aaron has his in the write up theres a few things i did different just using the stock wire for the fuel pump an getting a 12v switched off the old injector wire off the orange harness. I have everything else ran the way he has. Its kinda hard for me cause im using a 2.2v board not the 3.0 but this is my problem. I went threw my board as i bought it off someone on here. Everything checked out to what i had to do. I have the dual lm1815. I have leading spark but no trailing.

Im having trouble trying to find the right wire for the cas ne- g- were it goes on my db37. I dont know who makes my db37 as like i said i bought it assembled. But i used the msextra told me. I have my g+ ran to pin 31 like in the msextra. an my ne+ is to pin 24. were do i wire the negitives for both. also i have
igt-t pin 27 to the stock Blue/yellow
igs-t pin 29 to the stock brown/yellow
igt-L pin 25 to the stock leading green/yellow

I tryed to do it the way aaron did his nothing not even my leading sparked. i found on here some different was that they were ran an i still couldnt get a trailing spark. Please can someone help thanks

i hope this helps you ive personally havent worked on a 2.2 board. ALSO i double checked your pin outs and i think you have your trailing crossed switch 29 and 27 .

 

crap lol i might have put that wrong in the post it might be the other way around. ill have to check in the morning cause its almost 12 here heres a picture of my dual vr i cant find anyone with it so im wondering who makes it

 

the white an black runs around to the back side to pin 11 on the U1

 

brown runs to d2 unbanded
orange runs to pin6 of u4
white black to pin 11 U1
Blue runs to X14
under side Purple runs to D5 unbanded side
yellow jumper runs to jp1 first hole

Also i just checked my igt-t an its right pin 29 igt-s 27

 

Have you had the engine running? ms1 does not fire trailing below 800 rpm.

Ken

 

i didnt know that. but no i have not had the engine running yet. IM having so much problems with this db37 i wanna scream. but now that i know that i will figure this out

 

Not 100% if it applies, but i had no trailing fire, and it ended up being a software configuration issue. just my 2 cents

 

So how did you fix it? I'm kind of having the same problem

 

I never did. But i was told on the ms1 2.2v the trailing doesnt spark till after 800 rpm so it takes the leading to start the motor. So pretty much what i found is just make sure u have a good clean cas connection ran threw a sheilded wire make sure ur grounds are good an clean in good strong places. N it helped me out alot i got it running an stuff so now im kinda just fine tunning the little problems in the wiring
