Hello,

I've been back and forth the last couple years messing with this 01 miata that has given me headaches. Done plenty of searching, nothing that's help so far. Looking to get it done finally so I can start enjoying it. Here's a rundown of the setup:
GT2871 @ 10psi, FM manifold, FM d/p, FM full 3" exhaust, FM I/C and plumbing
Deaushworks 600inj, FM221 ECU
I'm at 5200ft elevation.

Tried using the base map that FM provided in the Dropbox and it wasn't good for my setup. I've been working the fuel and ignition tables and the car is slowly coming alive. At about 3K rpms, the car lugs a little when you punch it, slowly builds to 10psi by about 4K, then just struggles to push to redline. Hesitates a lot and almost feels like I'm towing a trailer. At 10psi, i would guess this turbo should give a nice hit, but something has to be off in my tables, because it is sluggish. AFRs in the midrange are about 12.5ish and timing is 22ish. WOT in boost, targets hits 11.5 afr and 17deg ignition advance. Not looking to squeeze every last HP out to blow it up, just want to car to have a nice push when WOT. Can someone send me a safe/street ignition map pic so I can try it out?

Thanks,
James

 

You'll probably ignore this advice, but: You should tune your car, or have someone tune it. Not plug in random data cluelessly and cross your fingers that it works.

 

Check mechanical timing.

That too

 

The DIY Autotune ignition map is just fine.

 

Just make sure to edit the map since the FM221 tables are/were upside down, compared to what Tuner Studio... at least when I saw it last.

Not sure what changes were made before it went "live" here in the US.

 

17 degrees at 10psi sounds reasonable, with 11.5afr.

I dont think ignition timing is your problem.

Have you changed the timing belt recently?

 

We dont make tune assumptions without a tune file uploaded so we can take a look.

 

Thanks for the replies! I forgot my laptop at work so I can post the table on Monday. As far as mechanical timing, I remember checking that when I installed the ECU about a year ago (the car sits alot). Doesn't have any issues starting, idling or cruising. Timing belt was done about 10K miles ago, double checked timing marks when it went back together and checked valve clearances. Maybe I should check compression? Car has 95K miles.

I'm not randomly plugging data into the tuner, I'm making educated guesses I had a 94 with a FMII @ 15psi 20yrs ago and that car ran awesome. It also had a Link, which was super easy to tune, and hardly any problems.

I'll also post my fuel table, which might help too? And yes, FM221 table are inverted compared to the MS3 tables I see posted.

 

I'd say that's even a bit retarded.
