Look over my tune?
2 Attachment(s)
I haven't really ever had an actual tuner (or someone with a lot of tuning knowledge) look over my tune so I figured I would finally throw it up here for you guys to take a look at :bowdown:
My car is a 1994 1.8 miata with an eBay 2871 48 comp, 550cc flow force injectors, a begi cast manifold and custom made downpipe mated to the stock exhaust after the cat (stock muffler keeps it quiet which is nice but I'm sure is bad for flow). I attached my afr table, spark map, and ve table if you don't feel like opening the actual tune and log. The log is a first thru third pull. The car has never been on a dyno so I have no idea what kind of numbers it would make, I'm sure nothing that impressive. I'm pretty new to all this but I am looking forward to learning a lot! Thanks! :D https://cimg8.ibsrv.net/gimg/www.mia...991a3cc53b.png https://cimg0.ibsrv.net/gimg/www.mia...4192b305b3.png https://cimg1.ibsrv.net/gimg/www.mia...7edb7edd2a.png |
I'd select your 88-120kpa row in the AFR table and interpolate vertically. That 100kpa row is too lean for me as you're transitioning into boost. Even N/A cars run 12.5-13.5 at WOT (100kpa). Not that you'll ever really be in that row.
Your ignition table needs a lot of smoothing and less timing in boost as well. I'd start by taking 6 degrees out of your 200kpa row, and interpolating all the way down to 116. You might even remove more to be safe until you hit a dyno. I'd get rid of that random 30 and 22 cell in the 116 row first, just for looks. You're also wasting resolution by having an 8000 and 9000rpm column, since you're never there. If you're only spinning to 7000 usually with a 7250 revlimit, you could make your last column 7200, maybe add a little fuel and take away 2 degrees, so it's always safer as you approach redline. Then move everything over and use your 9000rpm column somewhere that needs some more resolution. You're on a MS2 as far as I can tell, so try using it in the idle region to help stabilize fuel and rpm there. |
Oh god, is this a speedunio? Good luck.

Sure looks like speeduino, i have it, too.
My tables also needed a lot of work. Curly is pretty much spot on with everything! |

Sorry if my choice is not mturbo spec :cry:

Or do is that too lean? https://cimg0.ibsrv.net/gimg/www.mia...ea26a5e6b8.png Removed timing up top and closer to redline as you suggested for safety: https://cimg2.ibsrv.net/gimg/www.mia...1f77b64dec.png The VE table looks a bit funky but I'm guessing a drive with auto tune will help smooth it out: https://cimg3.ibsrv.net/gimg/www.mia...13aee31fd7.png |
