Trying to get started the RIGHT way
 

Hello every Miata tuners!

I'm looking to get a STOCK miata 1990-1993 miata Basemap for my MS2 Extra 3.2.1

I Recently bought the Megasquirt from blean99. It was preloaded with His tune. Well i changed some setting for my car but i just feel im going no where..It start, Its running rough and cant get into a decend tune enought to drive it.

I would like to start from the begining with a stock map. In my opinion it would be a lot easier. Or if anybody could make a base map for a 1990 miata 1.6 engine with 440cc, stock cas, stock tps, Gm iat. Well just to start the car and be able to take it to my garage.

Thanks

Download the MSPNP9093 basemap. Only difference will be the injectors which you can fudge with "Req Fuel."

wow! thank you very much! that was a fast reply eheh!!

Ill try this out tomorrow! I hope the car will run better!

mmm there must be something i dont get...


when i open the file you told me to download i get this message

NOOOOOOOOOOOOOOOOOOOOOOOOO

don't put a MSI map on your MS2.


you should have left his tune on it. it was based around that particular MS2 and all the inputs and outputs match how it was built.


Hornetball ball gave you AWFUL advice and I hope you saved a copy of the tune that was loaded. All you should have done was tweak a few parameters to match your injectors.



You have a custom build, ms2, by yours truly. Dont load MSPNP MS1 maps, MSPNP2 MS2 maps, DIYPNP MS2 maps, MS3 maps, or any other maps. please tell me you saved a copy of the loaded tune...

Assuming that he was using TunerStudio, a backup will have been automatically saved into the /restorePoints/ directory within his Projects folder.

Yes i saved it!! but still now no cluster tach whatever i do!

I attach the tune inside the Ms when I had it! this one is untouched! If anybody could set it right to me for 440cc, Stock TPS, Stock MS map, no AFM, And stock CAS. It would be amazing to be able to at least start the car and drive under 3000rpm to bring it to my garage to work on it! cuz now my neighboors plan on killing me.

regain the tach but putting a 1K resistor in the diagnostics box between IG- and B+. If if doesn't work with the Stock ECU now, then the ignition settings of the MS were changed from how it was built and the ignitor is burnt up.

Ok well i decided to go back with stock ECU for testing purposed, the car doesnt even as it was starting before. I checked spark plug for spark and i got no spark at all.

1- So if i understand correctly my ignitor is burnt up??
2- Will this have caused damaged to my megasquirt?
3- What should i do to Avoid this again?
4- Anybody Qualified for that. How much for a WORKING basemap, i'm just pissed, i dont want to run around all the summer, I work alot and i dont have much spare time

no clue anybody?

Not sure but perhaps the ignitor may have been burned out by the wrong tune being loaded (if something related to "spark inverted" changed) and trying to run the car?

Sorry OP. What I meant was that the MSPNP2 basemap would have VE and spark maps that might be closer to your situation.

I wasn't specific. I did give you awful advice. Sorry.

yes, this.


it depends on how the MS is built.

so how could i know if i need to set it inverted or not in tunerstudio?? anything i can see clearly in the ms like a jumper or something

well i tested my ignition switch.. looks like its receveiving 12v input in but not giving any output so hopefully tomorrow's coming fast ill try to find one ASAP to put back MS in once i can start it with my STOCK ECU

:facepalm: Dude, -epically- bad advice.

Steven: From what you described, all you needed to do was change your fuel VE maps or tweak injector settings (And I will remind you, I did specifically tell you this in PMs!!!!), not....I hope you the best of luck man, that was truly bad advice from Hornetball.

Re-flash to your previous tune ASAP, and copy fuel maps from other basemaps if you have to, but don't flash to random tunes in the future!

I also have to change tps calibration an set it to run on the stop cas coil and igniter since im not running on COP .

Well i hope i didnt screw my megasquirt . Ill let you guy know tomorrow if my car start at least on the stock ECU

Dude....

89-93 didn't come with a working vTPS if they weren't autos - and that wasn't setup for an auto. Stahp.

Fail thread

I'm not sure why we even bother. The sun is going to go nova in 4 billion years anyway, and when that happens, it won't really matter whether you have an analog TPS or not, will it?

It's all pointless. Just boil the oceans and get it over with.

Update: i change the igniter and put in new plug ngk bkr6e-gp and the car started

Then i put back the megasquirt with the original tune. I ajusted the req fuel for my 440cc the car running good except i aleays need to keep my foot on the throttle a little bit or i hear a relay click and the car just stop even if im at 3k rpm once i remove my feat on the throttle i hear that click an the car just stop

fuel pump; you need to make it run.

well fuel pump is running isnt it???

I can start the car. If the fuel pump wasnt running i would be able to make it start..

More info about that if you think my fuel pump stop running? I would say why and how can i fix that

you have the AFM in place?

Nope im running with the Megasquirt inside build map sensor.

and what are you doing to run the fuel pump on your 1.6L when you've removed the AFM?

well I removed the ST SIGN fuse then I plug in the megasquirt.

The previous owner of that Megasquirt didnt any issue with making the fuel pump running. The megasquirt is build to run in without modification to my harness..

I dont know why am i having such issue with it then

Is your MS built with the high side current driver outputting to 1C on the harness?


You need to understand that it requires a certain amount of silliness to get the fuel pump running on a 1.6L with MS. I can't remember if Blaen's unit had these nessecary steps taken on his or not.

Pull the ST-SIGN fuse is only useful if the unit has the high side driver cirucit built inside to run the fuel pump through 1C.

Otherwise, it may have been built to send a ground to 2O on the AFM connector and needs to be jumped to ground.

remember, you have a custom built MS unit, this is why you needed to maintain the custom tune loaded into the unit, just as the harness and wiring may not be built to any sort of standard. So these are important questions to ask you.

Brainy....Braaiinnnyyy.....Listen to his symptoms, not his theorized reasons why something is wrong!

Steven: You aren't controlling the IACV and are trying to idle with insufficient air - either you need to get the IACV working, or you need to increase how much air bypasses the throttle body via the idle mixture screw.

Fuel pump doesn't have a goddamn thing to do with why your engine isn't getting enough air, and the fuel pump stuff is perfectly fine if you removed ST_SIG

Hears a click, motor stops running, suggests to me the fuel realy is getting tripped off somehow.

I only wired maybe 2-3 units with the high side driver, I wasn't sure if yours was one when I fixed your harness.

Otherwise I wire the fuel pump through the AFM connector and it requires a jumper wire in order to work.

But, I was assuming the AFM was still acutally in place and allowing the fuel pump to run, and I was eventually, in a very long and drawn out way, going to get to lack of airflow causing it to close the flapper and the fuel pump shutting off.

i have method to my annoyance.

PM...

So yeah. Simple question of "noob needs to search".

Miata running with megasquirt - YouTube

i show you guys a video with my IAC valve set to PWN closed loop, no changes

stock 1.6 TPS? still plugged in? unplug it.

^
Did you unplug the TPS like it says to do in every 89-93 writeup (That I've read, at least), Steven?

Dude! I love you (dont take my words to serious ahhaha)

Guys seriously i searched , searched, read, re-read. Maybe i wasnt looking at the right place! I unplugged the tps and tada!! it worked!! I thank you so much to all you guys for your help! I'm sorry if sometimes im not really clear with my question. I'm learning and i hope oneday i can help someone in similar situation.

The car idle REALLY GOOD. The car is a little lean, ill work on VE table, ill hook up my wideband also to do things right!

Now I need to go to work but thanks again! ill work on it tomorrow ^^

i said it first!

You're right I love you too ahahah wow thi really make my day :)

lolol WAY TO GO HORNETBALL!!! YOU TOTALLY DESTROYED THIS NOOBS CAR NOW, HOPE YOU'RE HAPPY!!:vash:








:laugh: lololol jk

I'm thinking I may have earned some kind of "pile-on the retard" smiley for my efforts!

I saw that post edit, Brainy-boo! :wink: :giggle:

Seriously, I have to hand it to Hornetball - this is the first time I've seen someone manage to damage a noobs car with advice here!
