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.

Thanks, i'll work on smoothing it out

Ok, i'll have to tweak that as well. Isn't it 1.2ms?

Techsalvager

.75ms~

It seems like you dont know what youre doing. Being ignorant is ok but you are gonna blow the welds.

Uploaded a pic of your timing so others can take a look without having to open it.



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
