It's not so sacrilege as you think.

Actually, the EM in my setup, is a custom, DIY management with 8 injectors, and it is very easy to tune.
At off boost situations,cold starts etc, is like a stock miata. Something that is very difficult to find and tune with stand alones.

About the numbers

I am hitting 300 WHP at 15 psi
and 380 WHP at 25 psi at dynapack (very rich dyno)

The most pure dyno here in Greece is MAHA and gave me 370 bhp.

The dynos is a very big discussion..

But the car is very fast, it is a little faster than a porsche 997 turbo (480 bhp) from rolling 2 gear

I hate to join in with everyone else, but really nice car! I want a better pic of the exhaust, I wanted to do center exhaust on my car. If you get better pics, I'll host them for you no matter the size.

I also really want a pic of the manifold off the car, I have the Flyin' Miata fuel rail (well, I did until a month ago), and it was terrible, it always broke off. Have you heard of people putting race gas in the second injectors?


I really liked the piggy, but it had issues with not knowing what was going on with the OEM ecu. Went to a MegaSquirt for cheap and am rapidly getting very happy with it. It feels better off boost than my OEM felt on it.

hmmmmm
Um, yeah - I had that set up for years. Change altitude, take it in the ***. Fuel tabs fall off, take it in the ***. Try to control ANYTHING, take it in the ***. If I'd put all the money into a computer I'd put into new rods, I'd have a very expensive computer. :-)

I opened a new topic for the RX FD3s modification. I have this 1 year now and it works better than stock. (shifting etc)

Again here! For a very long time I have quit the MX5 tuning, but now it's a chance to post some new fotos of the last mods of my project!

These mods have been done at 2008 June but now I remember to post them
