Hi, I purchased my 1995 Turbo Miata a few weeks ago and have been slowly fixing and upgrading it since. It was tuned by the previous owner and I plan to have it tuned again in the near future by a highly reputable tuner in my area. Meanwhile, please take a look at my AFR, VE, and Spark tables and let me know what you think. I have a t28 turbo, 1000cc injectors, AEM 320lph fuel pump, MS2PNP, 15psi, and run solely on e85.

 

mediocre at best. most base maps are better than this even.
I can't imagine this car running/driving/boosting very well with those tables.

 

Target table blows, ve table has to drastic changes.

 

I am no expert and am just curious but isn't this very conservative for E85 on the timing side?

 

its all over the place. there is no one thing off, but many things in many places. it makes no sense. kinda looks like whoever tuned it is used to tuning diesels lol

 

Especially the spark map.

 

It's crazy how little spark advance Diesels run. In a previous career I was in charge of developing advance curves for diesel distributors.

 

Thanks for the input. I'm not that surprised with the comments as the car doesn't seem drive very well. I'm waiting for some parts to upgrade to COPs and hopefully figure out my overboost problem before drop it off at a tuner. What's a reasonable rate to tune? I was quoted by two shops for $500.

 

Is required fuel setup? That VE table cray cray

I'd grab timing from a good base map
