I started with this tune as my base map for my 99 swapped NA. I had to change the ignition settings for my CAS and 93 coil setup but it seems to be working well. I ran auto tune for the ve table and it seemed to improve my mpg without any noticeable drop in power. I started with 93 octane, then cautiously dropped to 91 then 89 octane and haven't noticed any audible pinging. I will say my motor is using lots of oil and I have a vvt motor waiting to go in so I wasn't too concerned about damaging it with low octane, but it seems to working well. I had to play with the idle settings and am still tweaking cold start.

Thanks for the info! What is your elevation? Have you dyno'd it yet?

I'm in the NYC metro area so I'm more or less at sea level. I haven't dynoed the car, but it definitely feels a lot stronger than it did with the 1.6 ecu.

Here's my '99 with a Reverent built MS2, tuned by Hustler. My car has stock intake, but RB header and Roadster Sport exhaust.

I tried the tune over the weekend and my car didn't like it so much. I think it is running too rich by the smell, which I'm fine with if that's max power but it felt slower. Is it because I'm at such a high altitude (4500 ft) that the afr/fuel tables are off? I am a newbie at tuning so if someone thinks otherwise, let me know.
I kept 99% of the settings but went back to my original tuner's afr/fuel/spark tables (which was a disappointing tune originally). |

I don't know the answer to that. I know that it was a Mustang Dyno, and that it reads low compared to others. Maybe Hustler will see this and chime in... but it's been almost a year since the dyno session...

Thanks so much for the help everyone. I am learning a ton!
I noticed that this AFR map goes to 100 % load. For a N/A is this what the target should be. My tuner looks to have taken the stock table and used 200% as the max. Does that mean my car really is only using 1/2 the table and thus is not getting fine-tuned settings? I did a log the other night and my max MAP was 89. How do you find the max load % you should use? |
Tune in the Northeast
Can anyone recommend a reputable dyno tune shop in the Northeast? NH, MA , RI, CT. With MS / Miata experience. Dent Sport was the choice until they closed last year.
