Default tunerstudio timing and autotune

i have 1 1990 miata with a 9093mspnp.
97 motor with vtps
the mspnp is modded for the vtps and loaded with the 97 firmware
Aem wideband, afr target tables in afr units
afm removed ait installed.
Using tunerstudio with autotune.


ok so i load the base map that comes with the pnp.
It starts and idles steady but it runs pig rich. 11.5
when i enable autotune it slowly corrects the cells little by little down. but the afr remains in the 11s and high 12s.....then all of a sudden it will start shaking go lean and stall. wont run again until i reload the original map. seems there is no happy medium. its rich or wont run. I have not attempted to drive the car cant even get a good idle dont want to damage anything under load.

anyone have experance using the autotune?
have photos of base map i can use as referance?

Im not looking for a easy way out here i just need help. i have been searching and reading and playing with the software for several hours a day.

tought maybe might be timing related but im pritty sure i did this that right.
there are two marks on the pully. i have confirmed the one lines up on the T mark and the other on the 10deg mark when the #1 cylinder is at TDC. in tuner studio under spark settings i set the fixed andle to 10deg and adjust the cas until the mark that was on the T is on the 10...but the confusing part is under tunerstudio it says (fixed angle set to 10 uses map) and at idle map says 16.
so should i turn the cas until timing light reads 16 and leave the trigger angle on 10?

yes, you never use autotune to dial in idle.
you dial it in yourself

you lock in the timing in both ts and the car (jump the pins). start car and time it at idle that way. if its way off 10* you adjust the cas, if its close you can just raise/lower the offset as needed til its spot on. once it is, you're done, disconnect the jumper and set back to "use table"

when doing this you're always aiming for the marks to line up not to represent what TS runs at idle

but the 10 deg setting in ts is the setting to use table. so if i set it to 10 the marks don't line up because it fires at 16.....and how does the pin make a difference? doesn't that only work with a stock computer?

you lock it at 10 in ts then you adjust the engine so its at 10. That synchs the MS and your engine so the timing it thinks your engine is running is the actual timing the engine is running.

dunno how to explain it any more simple tahn that

You don't need to jump the pins without the stock ECU. That was just how you locked the timing with the stock ECU.

As the stock ECU is now gathering dust, jumping TEN and GND achieves sweet f.a.

I understand the concept, verry simple. The part im not understanding is how to lock the timing for a inital setting. Because the default setting in TS (spark/Setttings/fixed angle)
this box lets you pick the angle. But it says setting it to 10deg uses the map. (10=use map)

So would i set the map to 10 temporarily set timing at 10 then readjust map?

Sorry if I'm just missing something. If you use tunerstuudio you can go under spark settings and see what i see. maybe you will understand my confusion. or maybe im just looking in the wrong place?

Have you considered reading the instructions from DIY Autotune?

That is the complete opposite of what I said

How would that even be possible?

1. If you don't correct this **** into something legible, I'm going to spank you.
2. Are you telling us that setting the static timing on your car is different from what's described in the DIY instructions?

You realize that we've done this before, right?

-10 uses map. Entering 10 will leave it fixed at 10 degrees BTDC. You enter 10, verify with a timing light it's actually sparking at 10 BTDC. If it does, you change back to -10 and the ecu will use the spark1 table.

I really didn't, why don't you try re-reading what I wrote.

What I said was that jumping TEN and GND was for setting the timing with the stock ECU.

If you don't have the stock ECU fitted then jumping TEN and GND will achieve precisely sweet f.a.
