Injector cut at 7psi.. please help
 

Hoping someone can help me out here, just got my miata up and running with a pieced together turbo kit and I'm running into an issue.

the car starts to pull great and then it hits 7 psi and jerks for a second and falls in rpms. At first I thought it was spark blow out so i gapped my plugs smaller and tried again and no luck. I looked over my logs and my injectors go to 0% duty at 7psi and stay at zero until it falls to about 5 psi.

Hoping someone maybe has some input on what could be cause my injectors to die out only at that specific load. I'll link the log as well thank you!!

Injectors are 420cc rx8
t25/28 hybrid from begi
running on ms2pnp

Perhaps you have boost cut set at ~7psi?

you can only set boost cut if your using megasquirt to control boost right? i"m running a mbc should have mentioned that. and my waste gate is set at 10psi.

I'm thinking it may be a boost leak just not sure if that would cause my fuel to go like that.

Overboost protection.

Check it out.

lol found your problem

heck man as soon I can figure out why my injector is going dead i'm turning the boost all the way up haha. I'm gonna change my name to 40psi

Erat!!! I think you solved my issue! I'm an idiot for over looking that. Brb gonna throw 30 layers on and go for a test drive. (gotta love pittsburgh weather)
