Miata with SAFC and 440cc hard to start

Im already using a map sensor instead of the TPS sensor as the "fake tps signal" in the SAFC. I knew that already i just forgot to mention it.
And as you can read clearly like i said. Its really giving an IMPRESSIVE pull for the 800$ I spend... i doubt you could find a miata with a total of 800$ engine mod to pull that good as mine... not saying im the number 1, im just saying i think i did good with a budget that low. I planned at the beginning a 1000$ turbo kit just for fun.
Well anyway i'll try to figure this out tomorrow.
BTW if it could interest anybody i made a video of my miata project online if anyone curious to see how its running

Being proud of that, is like being proud of a giant smelly diarrheal dump you took in the bathroom.

Most people here spend more on engine management than you did on your entire turbo system. Which is why theirs start and yours doesn't.

If you have $200 of budget left over.... Buy a megasquirt, sounds like you already have a wideband. For $200, you're looking at used, or even a Ms1. Either will actually work vs a piggy back which will always be a dangerous compromise.

How ridiculous does this sound to you? because what you have told us OP is not far off.

Are you having fun with your car that doesn't run even close to right at the moment?

If youre still listening, THIS^ is real advice. If you had spent 10 minutes searching you would have known this.
This forum is so tailored to budget enthusiast that you see it mentioned in grassroots motorsports, but even we consider an MS1 a MINIMUM. Anything less is dangerous and stupid.

Sorry if I skipped over it, but is the SAFC tuned? Like someone mentioned before, it sounds like the car is super rich when cranking. It would be pretty easy to use the SAFC to pull fuel below 500 or 1000 rpms and hopefully resolve, or at least minimize, your cranking issues.

Are you insinuating that you can actually tune with an SAFC?

That much i knew.... i have one. I just figured it belonged in a museum display case along with this freshness i'm putting in my display.
Although.... my SAFC looks too modern.
Maybe i need one of the originals that was just one **** that adjusted the entire rev range at once. As you can imagine, it was REALLY useful.
ACHIEVE THE DRIVING HIGH. APEXI, IT'S THE SUPREME.
Then they were all like **** GUISE!!! WE NEED SOMETHING SUPER!!! ADD MORE *****!!!

"because its a piece of junk, it cannot manipulate start up enrichments, therefore pulling fuel at low rpm will simply make it super lean when its actually running"
that and the fact that OP said its already on maxed out trying to take out fuel.

I'm gonna go with something along the lines of:
"because its a piece of junk, it cannot manipulate start up enrichments, therefore pulling fuel at low rpm will simply make it super lean when its actually running"
that and the fact that OP said its already on maxed out trying to take out fuel.

This, to the point that he's started to **** with the spring in his air metering system...
Which you know, tricks the ECU into thinking the load being presented to it is less than it actually is.
Sooo.... YAY! MOAR TIMING!!!!!

hello again miata turbo peeps!!
I just wanted to update you guys about the solution I used!!
I simply put a relay on the fuel injection fuse (keeping it fused of course) this allow me to cut fuel injection for the first 2-3 crank then activate it and start perfectly!
BTW thank you Leafy, your answer was clear and simple and you where polite.
