Crank no start
hello every one
I have a eBay turbo set up in my 95 Miata
setup :
yellow RX 8 injectors
fuel pump 200
BMM,ECU (rus efi)
so the problem I have the car starts fine on a cold start but it seems to have little power whenever the car is up to temp. For example, I drive around for 15-20 minutes. Then I go to turn the car on it seems to struggle I go to turn the car on.and it doesn’t turn on, now I don’t drive it everyday jus every so often I take it for a spin but I have to wait like an hour before I get to leave because it only starts when the engine is cool
I got my car tuned in October now I know temperature has a big role when it comes to tuning, as of now, my AFR‘s are reading as following
Idle 9-10
When I give it throttle straight 9’s
lettinh off throttle 14-17

To start, post your tune and a log of the concern occurring.
Right off the bat, the information you’ve given indicates multiple things in your tune are whack. 9-10AFR at idle is way too rich. Maximum, you should be in the low-11’s at full boost.
You said it goes 9-10AFR when you’re on throttle. Can you elaborate on that? Anytime you’re on throttle or what specific conditions?
Again, a tune and log are the only things that will keep us from guessing.

I would clean and re-tighten all grounds and verify none are missing.
I would then ensure the timing belt hasn't skipped a tooth.
Then I would take a log of it running cold, then one of it running hot and then attempting to restart it hot. Post those and the tune file.
