I don't think the coil really needs 3.6Ms to charge fully, that was more of a test, hence the disclaimer on I wasnt' sure if this was the tune I ended up with or not near the end. I did some comparisons on tunes and took some notes, and two of the pulls in the middle of the day actually netted 5500 ...

It's a turbo car, and the high advance (down low) helps it spool up fast - it's not WOT tuned yet, so - obviously the lead will be pulled WAY back under boost.

The abrupt rise in temperature came from a partially filled radiator, but I figured out the real problem yesterday.

There were two ...

I've FINALLY got this thing running, but not driving it just yet - but just idling for no certain amount of time, or no apparent temperature threshold - it leans out and dies.

I've adjusted ASE/WUE, squirts per cycle, just about everything fuel related I can find and the problem still persists ...

since this thread directly pertains to what I was going to post..

I had a heck of a time getting my project to start, it wasn't until I took a wild guess at the timing bieng the culprit as to why it wouldn't start - but I had the offset set anywhere from 20-60*, and all it would do was vrrrrrrrm ...

So, Phil - what have I missed? Does anything in the .msq look out of place?

It's getting fuel, spark etc.. but just won't crank, and seems to flood EASY.

FWIW, I just changed coils too.

Are there specific settings for the VR sensor/reluctor that I might not know about?

Yeah, I sure did - the only part I wasn't sure of was the editing of the settings.ini. I don't see that .ini anywhere in a tunerstudio project.

I used the settings on this link - http://www.DIYAutoTune.com/catalog/mapdaddy-bar-map-sensor-with-barometric-correction-p-117.html (that's where I got the ...

A quick rundown - this is a COMPLETELY new build. I have had TONS of problems from one thing to another.

This is a V3 mainboard, Tunerstudio V0.999.9b - I recently [finally] got this thing 'running' if you want to call it that. It was running, but running RICH, so rich that it woudln't rev freely ...

Please draw up a COMPLETE wiring diagram for the MS system, one that shows where EVERYTHING is getting power. This does not sound like a VR sensor input issue - it's something totally different.

I don't have a way to draw complete schematic - but I promise, it's exactly like what' shown in the ...

I've created a different thread - maybe this topic isn't relevant to the original post, but the .msq is posted over there too for anyone who wants to see it. Now, that I've ditched the HEI 7 pin module and the MSII is getting signal direct from the VR sensor, I'm getting some wierd problems. As ...

I did test that - it's dead. The wierd thing - when you kill power, and the pump continues to run, you can hear it slow down.. once it gets to a certain point, the fuel pressure appears to take over (?) and the pump gets pushed backwards, or at least that's what it sounds like it's doing. There's ...

I did a bunch more reading and never saw a distinct definition of what you gain with the module and without.

Having said that, I changed over to the high current circuit and deleted the module and it briefly started and runs super rich - so rich that it dies easily. It floods super easy, mainly ...

I decided to ditch the HEI 7 pin module since I was having so many problems getting the truck to start. Switched to VR sensor only (which is from GM HEI). Added the high current circuit and ran the VR sensor wires direct to the relay board to TPS return (green) and Tach (Yellow). The tach wire goes ...

What's the gain/loss in functionality from one to the other?

My thing is, I'd like to lose one component that may not be needed - particularly the made in china HEI module. lol.

Ok, I'm filling in the blanks slowly but surely -

65. It is choice time again. In this case, you will decide whether to populate the high-current ignition driver circuit. This circuit can be used to drive a single coil in a distributor application. In conjunction with an appropriate input signal ...

OK, I did a bunch more research based on what you said above -

It appears you don't have to use the 7pin module with the V3 mainboard? (do you still get timing control?)

The diagram above came from here - http://www.megamanual.com/ms2/GM_7pinHEI.htm

For using the HEI with a relay board:

Pin R ...

you'll have to forgive me - I'm a MS newb and not totally electronically savvy - Not sure what you mean by conditioner. It's wired just like that diagram above.

Matt -

As I lay in bed last night thinking about this problem - I thought of the same thing you just mentioned. The dwell..I can't remember what it's set at, other than I think it's the default. (I'm at work and forgot my laptop.)


Also, Since it's using a VR sensor - I noticed that I had forgot ...

...continued.

I finally got the thing to have spark and fuel - but still won't start. For whatever reason, I had it wired/jumpered as if it were using a hall sensor instead of the standard VR sensor used in my HEI. Mine is wired like this diagram -

I've ...

This is on a typical SBC with HEI ignition.MSII V3 board, relay board etc.

I don't doubt that I've done something wrong, but for the life of me, I can't find the problem. It sounds as if it's trying to start, cranks stumbles, and just won't fire off..it won't even back fire. Even in if you crank ...
