90turboMX5

So yesterday when I got out of school my car did not start. I had to call my dad to bring the laptop and change the settings on the cranking stuff, I richened it up and it started. (I was using Braineck's settings).
So I kept the settings that worked but this morning it did not start and I had to walk 20mins to work when I was 10 degrees outside.
Can somebody give me something that works, I've mess with them but cant get it right...
My setup is
2554
MSPNP
460cc injectors.

I may just make the drive from Indianapolis to the DIY shop in GA this monday to dyno tune everything, but in the mean time I need to use the car.

lower the cranking PWs.

But I was using your cranking PWs settings (low) and it didnt start then I used other PW values that I made (higher) and it started. But yea maybe the ones now are too high and need to be in between of yours and the current ones, I'll try.

Start low with your PWs, low enough that you know it won't start. Then increase it .1 at a time till it starts and add another point. Should be golden after that. Only change the PW that correlates to the temp the CLT sensor is reading.

IIRC last time i checked i used 3-4ms at 50° with 460cc injectors the values i gave you were untested in cold weather and i couldnt start my car either.

Just to be clear, I'm not complaining, I took your values and just put them in my MS. Those values were posted by you for someone else, so its my own problem.

And he's explaining why its not working

chop, chop...get to figuring it out

i think last time i posted any cranking PW values, my fuel rail was also leaking at the same time and i was having trouble in cold mornings under 50°

my latest and greatest values are:

-40 5.2
-20 5.0
0 4.7
20 3.5
40 3.1
60 3.0
80 3.0
100 3.0
130 2.8
160 2.8

they may or may not work perfectly for you. it's just one thing you'll have to experiment on your own, but start low. if you start backfiring, it's too high

Today it was 33 degrees indicated on IAT.
I started with the following:
20F = 2.5
40F= 2.5 and raised the numbers slowly by .1 up to 3.5 when it started backfiring like gunshots but it wont start!!!!!!!! and I need to go to school tom.

I took the plugs out and they are black and covered with gas, what should I do, i think the engine may be flooded.

yeah, dry the cylinders out and try again.

90turboMX5

Well, I dried the cylinders with compressed air and cleaned the plugs with thinner. Before I put the back in I checked for spark and there's no spark going on any of them. I thought maybe my coils fried and put my spare set in and still no spark. Now it wont start even in the garage which is heated at 70 degrees. Wtf

Braineack

not sure, burning a few settings and trying to start a few times surely wouldn't fry coils.

90turboMX5

should the plugs still work even if the electrode is black? I mean they dont have carbon "deposits" they are just kinda black

kinda black and kinda wet? You can foul plugs with too much fuel. You either have to dry them out or replace them. If that's the case decrease your fuel alot before replacing otherwise you'll just wet them again.

yeah they'll work. do you not even get spark from the wire to a ground point? lay the wire near the tow lift hook thing and crank, you should see it spark. I'd have no clue why they would have stopped working. is your ignitor hot to the touch?

90turboMX5

From the wire? I attached the wire to the spark plug and lay the spark plug and the tow lift hook and still no spark. The ignitor is not hot. The coils should be fine, maybe its some MS setting, but I loaded different settings that I saved and used to work and still no spark.
If you guys have any tips please let me know, I'm going to get it tune at DIY's shop on Monday but first I need to make my car get there.
Can somebody give me their MS file? for 460cc would be best

90turboMX5

Ok I found the problem, the igniter was not working, it burned!! this is really getting to my nerves, first the tachometer stopped working, now the igniter breaks. I put another igniter from my brother's miata on and it started, rich as hell though. I took the car outside the garage and left it in the cold. Started with low PW's (2.5) and went up to 6.0 but it wont ******* start, it probably burn the igniter again.
AND NO, I never uploaded firmware with the igniter connected.... this is bs

you probably have it set to inverted spark, you don't want that with the mspnp

90turboMX5

I had it set like that and I turned that setting off. I checked for spark and the plugs have spark, but it wont start. I dried the cylinders again and tried and it wont start. Im getting rreally sick off having to call people to take me to work, etc. This is just ...... I need to fix it
