ok im going to pull my intercooler pipe out so i can get to the ground on the driver side fender cause its almost impossible with my power steering an ic pipe. But ill clean that one up an ground the ms to the engine an see what happens

 

OK so i grounded it to the battery cleaned up the driver side ground shortened up my cas wire. N it fired up. hopefully i dont run into no more problems an i can start tuning n junk haha. THANK YOU SO MUCH KEN i really really apprectiate your help.

 

No problem.

 

well that little grimlen came back today. came out to start it fired up ran for about 30 secs n shut off. Then wouldnt start again i went over all my grounds added a few cleaned up some stock one same thing. Started ran shut off. I know my fuel pumps on cause i can hear it n my fpr says 40 when it stalls.

 

hey ken were is tooth 3 cause i thought ne was the red an white wires on the cas n thats the bottom pick up

 

ok well i dont know whats going on but i had to reflash it once AGAIN I dont know whats going on. I got it to start but now i have a really crappy tach signal an my ms leds are getting dim then bright like its loosing power an trying to shut off. i guess im getting alot of noise somewere

 

That sounds like the MS is losing power or ground.

 

humm ill have to check it out now im going out side to see what i can find

 

ok so i did the 1379 an it seems to be starting a little easier. I restabbed three teeth counterclock wise. So thee teeth down from the two tooth. also i took my hold ign n advance down to 0. my crank angle i took to 60 insted of 65. it seems to be running better. is this good i read some were u said to do that

 

ok so I'm having a weird problem now. I got it running good an stuff. But when I let it sit over night, ill go out to start it ill jump in it will fire up an ill start to back out an it shuts off soi about 30sec or so give or take. If i let it sit for about 10 15 min it starts. Today I couldnt figure it out so i unpluged the harness an push the cpu chip in thinking maybe it wasnt far enough in. But it was so i said to my self humm. PLugged the harness in tryed agian an vroom. ran, I drove it for about 10 mins had a few warm up problems i need to go threw but other than that what could this be. Is it maybe my warm up wiz fuel isnt high enough or something else.

 

oh yeah also i for got to mention. That when i first wired everything to the db37. I had the fuel pump wire an i wasnt getting anything out of it. I use my volt meter an even on cranking nothing so i had to run the fuel pump off a switched 12v source. I know its not good if i wreck but could this also be a part of my fuel problem like maybe the ms is loosing fuel pump an stops injectors?

 

You'll never see voltage out of the fuel pump wire - it's a ground, not a power-up.

Did you ever verify that you're not losing power or ground to the box? Watch the system voltage on whatever tuning software you're using.

 

mother fudger hahahaha i thought it was power damn now i feel dumb hahahha. im still wondering why my car shuts off though. Ill have to check out what u said about watching voltage drop i dont think so cause if i wait an once it warms up i can drive it all day

 

so i tryed running my fuel pump with the ground off the ms to my relay an nothing no fuel. so i just wired it back to the way it was

 

if it dies after 30 secs or so, watch the wideband and see whats happening, maybe it needs a bit more warm-up juice

for the fuelpump relay, connect one side of the coil to +12v after the ignition and the other side to the ms2, then you can go in advanced-->output test and it should be working, if not you might somehow have fried the transistor..

I don't own a MS2, but normally you need to use a flyback diode on the transistor, but probaly this is standard equipment on the ms2..?

 

ms2 and ms1 both use the v3 board, and that has a circuit for flyback.

Ken

 

i dont think i have a flyback board. mine is just the normal bored with all the stuff changed to run all the stuff i need to like the dual vr bac diode an the transistor to run the bac. the one on the q4 or q3 the bord is out side in the car lol.. i just drove it an for once it runs. im having some little problems need to adjust my 02 voltage. N maybe another ground to the engine cause i have it to the battery

 

if you have a v3 mainboard, it has the flyback circuit built-in.

Both the 2.2 and the v3 have a flyback circuit for each of the relay outputs as well.

Ken

 

well i think i have it all figured out. i finally got it all good running an when i would move the ms it would shut off.. So i had to figure out what was going on. I changed my db37 female an now it seems to be running great.

 

same damn thing i move the ms an it will shut off then i have to move the wires around an it will start up. Idk wtf is going on. I checked all the wires there all soldered an no breaks in the wires.
