Some of the setting aberrations will be my fault. My crash course in the MSII was basically setting up his unit. Before then I had never seen one...

Thanks guys ... Interesting thing about the cranking set higher than needed. About the Baro% i was asking how much percentage wise should I be be increasing, not explanation

On the baro thing, I think we're talking about different settings. Don't bother messing with the barometric correction settings at this point, doing that may just confuse things further.

ya i was thinking of something else. So i made the right changes needed. But I'm just wondering I changed the RPM limiter min to 8200 and max to 8500 how do I get the guage to display that?

muythaibxr

Oh, the gauge can only be changed by changing the megasquirt-ii.ini file.

I had a quick browse in there (the file that is all in text correct?) where about in there would it be?

muythaibxr

I'll look it up this weekend and respond.

Ok so I got some datalogs, and I just realized I was doing something stupid today. I forgot to hook up my vacumm hose to my MAP sensor. I'm guessing that would of made a world of difference. This is only today though, it was on it before. I have 3 files in the zipped file

Got your email with the datalogs. I'll be at the auto show all day today, and tuning the widebody car tomorrow so I don't know when I'll be able to give it a good look. Might have some time tonight though I am assembling a 'Squirt that needs to be done soon as well.

Any Help would be greatly appreciated. Just so you know Aaron next time you're here, I'm taking you for dinner at the Keg ... for all the times that I've troubled you. But i really need to have it done before may because thats when I need to be in TO to get my tuning session from BDC

After a bit more trouble shooting, I actually think that my problem is in the Ignition system and not too much fuel being dumped. I have tried taking out the plugs and testing thing against a ground while trying to crank with no go. Now I presume Pulse width refers to the spark plug pulse length, so if I see a signal going out from the megasquirt, it might be bad coils? I pulled them out of the yard without really testing them as I don't know how to. But its weird as how it would turn over for a few second though and not again.

Edit: I'm almost 100% Sure that its a bad coil, atleast the leading is. When I take the connector out, the 12V that is suppose to stay on is always there, and then I test the second one that suppose to turn it on and off, it fluctuates in the .3-.6 volts IIRC Would that be correct?

muythaibxr

.3-.6 v on the signal wire sounds about right at cranking speeds.

Sounds like a bad coil to me.

Tried another coil, and still nothing. But we might of tracked the problem down. Will be trying on friday probably. I have a stupid question, when turning the pots fully conterclock wise its basically turn them till right before they click correct?

These are the voltage readings from them:
Closest to the edge one:
Square pin - 0.01V
Center Pin - 0.01V
Last Pin - 4.84V

The one in the center of the board:
Square Pin - 0.54V
Center Pin - 0.02V
Last Pin - 0.01V

Also does the voltage feeding to the center one seem low to you guys? Or is that how its suppose to be?

muythaibxr

I've never tried checking the voltages, but I have several working MS's that I can check them on when I get a chance.

You're correct on the "fully counterclockwise" thing.

Ken

Also another thing not sure if it would matter or not, but the pot closest to the edge of the board is only reading about 500 something ohms, and looking at the megasquirt manual its suppose to be 10k?, the one in the center of the board is 100k like it says.

muythaibxr

10K and 100K are just the maximums, turned fully counter clockwise I don't think either of them will actually read its max. The measured resistance will also vary slightly when the part is in the circuit.
