Take a look at my log?
Hello MT users. I'm very new to tuning so here is my story:
Miata 1990 1.6L
rc 440 injectors
DIYPNP MS1
Variable TPS installed
AEM uego Wideband
Meth injection, (Disabled for now)
BKR7E-11 Plugs
93 octane fuel
Jackson Racing Supercharger w 10 lbs Pully
I've done all of the tuning on the road, the car feels powerful but I'm worried about how safe of a tune I've actually given her.
My issues:
1) After cranking the car it starts and revs to about 4k and then settles at an OK idle. I've adjusted the timing so it would idle normally.
2) Randomly during a hard pull the car will hiccup and then keep going. Hard to reproduce but it happens too often. (Timing issue?)
3) Fuel enrichment settings for acceleration are wrong or disabled. When I'm cruising and quickly throttle the car, she leans out and then recovers.

I'd appreciate it if i could get some input. I believe the AEM reading on the laptop is a bit more lean than the gauge on my dash is? I've attached my datalog and my tuning file for ms.
Thank you!

I can't get your MSQ to open in Megatune or Tuner Studio. However I can tell you that you are 1 full point too lean in boost, I say you go no leaner than 12.0:1 at your output level. I'll let you gamble on which output is calibrated correctly.
1) What is your "fixed MAP value in the ASE window?
2) What is your plug gap? Drop it down to .020" and try again
3) Tune your enrichments then, it's not hard. I recently made my GF fine-tune them on a road trip to the track. I never could have put that much detail into it and holy **** is it phenomenal now. It probably took 30-45 minutes of driving and they are great, better than factory. No matter how hard I stomp the pedal it goes right to target AFR.

I too saw that the OP looked lean in boost, and what is up with the AFR leaning out at as the RPM rises? Oh NM, I see you have boost sag.
OP: No log of your hiccup?

2) Spark gap is set to .020 I researched this when i installed the plugs
3) I'm not sure how to tune enrichment's. Do you have a quick n dirty way of explaining this?
Thank you for the feedback!

1) Not sure. I didn't auto tune and I gave the O2 '0' authority on my AFR's (i think thats what you're talking about)
2) Spark gap is set to .020 I researched this when i installed the plugs
3) I'm not sure how to tune enrichment's. Do you have a quick n dirty way of explaining this?

2) ok
3) You increase or lower them to get the number you want, it's pretty self explanatory. WTF else is there to say? If you stomp the throttle and it jumps above or below target, then adjust it accordingly.
