i Have a miata 1.6 with subaru wrx turbo,megasquirt pnp,toyota gianza turbo injectors,walbro fuel pump 255,

when i rev the car all the way till redline,or a use the lunch control,i will get a miss firing for a few seconds,and then it clears out and idles like normal
already changed sparkplugs,gaped them to 30
cleaned and flow tested injectors,but the same problem?
can any body help?

 

When my missus fires at me, I usually return the favor.

I had to gap my plugs down to 0.024, and I also once had to fix a misfire caused by poor ECU grounds.

 

Huh?

Data logging + tuning

 

please datalog the event and post it here. post your MSQ in the meantime.

 

I eat way too much because my lunch control isn't hooked up!

 

I remember my car did this. I don't know if it still does, but subscribing for answers as to why it did it.
