no, only the 1.6L 90-93 AFM cars.

yup, run a wire from the 'hoops' in D14 / D16 to iac2b and ign.
You already built the tacho circuit, so all you need to do is run a wire from the resistor in D15 (= tacho out) to whatever spare pin you have on the db37, like iac1b or iac2a.

Awesome thanks again for all of your help guys. *fires up soldering iron*

Had a thought, what would I need to run to the stock ecu if I just wanted it to control the alternator? I'm picking up my NA alternator in a few days but would like something to hold me over till then. Would it take more than 12v, 1o and 1t?

Jesus christ were did all these come from? Is this just from converting a ms2 diypnp tune to a ms3 v3 board or did I seriously screw something up?

Anyways I'm trying to convert diyautotune's base tune to my inputs/outputs but I'm really having some troubles because it seems like when I finally find a place to change what I need to, the input/output I need to change it to isn't there. For example the cam input options are only js10 and ms3x cam in but i don't have ms3x and i'm using js10 for spark out.

Frank you don't have a n/a tune that I could take a look at do you?

WestfieldMX5

I always start with the default tune and manually copy over the settings. Saves you a lot of headaches.
If you want to save some time with the fuel / ign / afr tables, export them prior to loading a default tune. Then simply import them in your default tune and do the remainder manually.
I have a n/a msq here. It's for stock injectors.
Here's my current turbo msq with RX8 injectors. Prime and cranking is better on this one. That msq gets updated nearly every day (I play with the prime / crank settings daily at the moment).
Mind you, these are for MS2Extra 3.0.3u firmware.
I'm running PWM warmup and normal AE. Can't be bothered by figuring out how closed loop works because I have a very basic car with no sudden load changes (no heater, no electric windows, no radio, no aircon, no nothing except for lights, indicators, fan and heated front window - maybe I should call it Yugo instead of Westfield ).

**** my life, went to start the car today (with stock ecu) and the starter will crank fine it just won't turn over, plugs look fine. Did I fry my coils? I had my megasquirt connected last night but didn't flash firmware or turn key or anything, don't even think i wrote anything, too it, just hooked up to to check for errors (see above)

It is possible that you have fried your coils if you got an MSQ from a DIYPNP that has the "Spark Output: Going high" option selected instead of "Going low" - depending of course on how you built your spark output circuit (did you use DIY's circuit or Joe's inverted output circuit?)

Well I just followed franks, I'll have to look and see but i'm pretty sure they're fried. Well, Guess I should take the opportunity to go to cop. Can stock ecu run the cops setup? How hard is it to get the connectors? Can I pick them up at oreillys or something?

WestfieldMX5

mine are both set to going low so should be fine.
You can run cops on stock ecu. Stock ecu has longer dwell but the cops have some internal protection against overdwell. Although it works, I have no idea how that protection circuit will work in the long run (but several folks are running fine with stock ecu and cops).

Golferluke

Well I loaded your na msq into the lapttop and looked around at it, still came up with sixty something errors. What does all this stuff mean? Any idea why my coils fried? I don't want to go through all this work changing to cops and then just pop another set. This stuff is so overwhelming, and I can't even teach my self because aperantly i can have $200 fuckups without even knowing what happened.

WestfieldMX5

Best to do as I suggested, manually.
Reflash your MS with 3.0.3u so you're sure that the firmware is ok.
At that point, you'll automatically have the base tune loaded.
Open Tunerstudio a 2nd time and open my msq. That way you can compare each menu side by side. Just copy over all the settings and you should be fine.
Export my fuel / ign / afr tables and import them in yours to save some time.
Afterwards make the entire fuel table a bit richer (say 5 to 10%). It's better to autotune from a richer tune than to autotune from a leaner tune.

Golferluke

Thank you. So will all the stuff transfer over? I just didn't know if I needed to change things from yours.

Edit: I guess since my coils are out of the car I don't have to unsolder the spark wires to reflash it

WestfieldMX5

All the stuff doesn't transfer over from one copy of tunerstudio to the 2nd. What I mean is that you can switch back and forth between both sessions and manually enter all the values I have in my stuff to yours. The tables are a lot of work, so those are more easy to export / import.
Even if the coils were in the car, you wouldn't have to to unsolder. Just unplug the connectors on the coils themselves.
I've burned one out a while back as well. No idea how it happened, I wasn't uploading new firmware or anything. Melted the connector also.

frank he's building a ms3, so he wants firmware v.26

WestfieldMX5

oops, slipped my mind ...
as Brain says

more raison not to load my msq's but to do them manually

Golferluke

ITS ALIVE AGAIN! Ok so its on the stock ecu but after a week its nice to hear the miata purr again. Got my C.O.P.s going, started first try. Anyways... back to megasquirt town. I started with the default ms3 tune and manually copied over everything from franks tune but it won't turn over. The starters cranking it solidly, it sounds like it wants to soo bad but just won't start. I'm thinking thinking no spark. (very similar to what it sounded like when my coils went out)

Do I need to change my spark settings because I have cops now?

Heres my current msq

WestfieldMX5

you sure the spark outputs are not swapped?

Braineack

iTrader: (62)

if the outputs were swapped, it would crank then almost stop mid turn and like it got caught-up.

Golferluke

I can try switching them but it doesn't sound like it almost gets caught. I got nothing better to try so i'll go swap them real quick.

Oh btw I don't have the iat sensor or wideband hooked up, would that matter?
