Critique my tune please :)

Hey everyone,
Finished my turbo build, had a few hiccups but mostly all is good i would say. I've been driving her around for about 2 weeks now trying to smooth things out and have a nice solid tune. Mind you i'm new to tuning and normally just take my cars somewhere after i build them, but i wanted to try something new and exciting. With that being said, here is my latest tune and i would like for some criticism on how to smooth it out some more, how my timing map looks and improve throttle response even more. I've used other members maps as a general guideline to help with mine. Areas i think i need the most help with are the idle, idle droop, accel enrichments and cold start enrichments. My setup; 1991 w/ 1.8 swap 27x9x3 Intercooler GT2554R Tial 38mm EWG Artech manifold w/ 3" downpipe, 2.5" testpipe, 2.3" RB midpipe to a 3" axleback MSPNP 1 FC RX-7 oil cooler Rx-7 460cc injectors Future plans include full 3" exhaust and i'm already tired of the GT2554, looking into a GT28RS in the future and a built engine with 6 speed. I've attached my most recent MSQ and datalog file. Thanks again!

OK I looked.
for your fuel map, at 90kpa @ 5500? why is this cell higher? also your spark table is jacked up. why. |
Thanks for looking.
Well, that is why i'm still working on it :) Care to elaborate on the spark table? |
Spark should smoothly ramp to redline.
If your tune is on the edge of detonation then you may need to have flat timing at MBT |
wrong dead time for the 460cc injectors.

I looked...apparently that mad tyte hella flush wing is causing your brain to not comprehend proper tuning capabilities. In all seriousness. I'm on my iPhone. If I looked at your map I'm sure I'd have a wildly different opinion:
Insert clip from 80's movie "back to the beach" starring Annette funachello and Frankie Avalon now: and also Lori Louglin when she was young and hot. It's the part where the son says: "I have a wildly different opinion". |
Oh yeah, I'm also all hopped up at the bar and just did a shot of bird dog. If you're not familiar, then get familiar.

Ok, i'll have to tweak that as well. Isn't it 1.2ms? What octane gas r u running |
Lmao hey gotta start somewhere that's why I figured I'd ask for help. It's a learning process just like with anything...

Uploaded a pic of your timing so others can take a look without having to open it.
https://www.miataturbo.net/attachmen...1&d=1338163665 You may have already looked through, this: https://www.miataturbo.net/megasquirt-18/dyno-tuning-take-look-fm-we-want-your-timingz-18648/ your timing map looks very familiar to one posted there. It's a great thread to come up with a basic timing map, just remember to be conservative with it and try to take input from as many similar setups as possible. A few of your low rpm high load cells seem pretty far advanced to me. The high RPMs looks fine to me. I love the car, it looks great. |
Your map sucks.
Also at 93 oct you can prob run more Timing. |
