My motor was the one that Andrew was putting together when he noticed the issue and decided to create a thread. I had it exchanged by ATI and Andrew installed the corrected unit.

 

Make sure to tell your tuner he is making engine killing timing maps.

I doubt he will admit guilt and compensate you in any way, but he might rethink his timing maps and hopefully wont kill future miata customers engines.

 

Goddamn those timing maps. WTF.

Too bad youre not closer to me. This wouldnt have happened if I had tuned it. Thats not saying much though, this is some seriously incompetent tuning...

 

why do people stray much from the DIY spark maps? I thought they were vetted a long time ago as being pretty solid, with the tuner map being real good. What happened to that? or am I totally wrong?

 

The map that came on my MS3mini was really good, I just tweaked it a bit in the mid range and top end. I have no idea what the guy tuning this car was thinking.

Over the years I have met countless "professional tuners" who are at the peak of Mt. Stupid. They know just enough to be very confident and very dangerous.

 

I dont think so when you're on a built engine / change in compression. Not to mention different fuels.

 

I think they recommend that the "tuner" map be used with 91 or better gas, not corn. Also "tuner" implying not stock and more advance. That was how I interpreted it anyway.

 

******* lol IRL @ 27deg of timing at 200kpa on 93 octane. That's incredible. I would start a conservative gas tune by literally taking your timing map and dividing it in half.

Please post the name of the tuning shop so I can tell people to avoid them.

 

VA Beach and someone mentioned Peter...I hope not.

 

PF Tuning would be my guess from the clues provided...

 

Pft?

 

Wow this is concerning as I just had my car tuned by Peter this weekend. My timing map looks quite different however. He basically looked at the map I had (MS3 Basic base map) and said it looked spot on. Pulled/added 1-2 degrees for two pulls and when they showed a loss in power just put them back.
This still makes me nervous. Can anyone verify that this looks sane??





Stock NA8 motor, 93 octane, haven't compression tested it.


OP that really sucks...

 

That table looks fine, very close to what I'm running and 10 degrees less than OP.

 

Looks fine to me, its actually pretty conservative, my map is a bit more advanced in the cruise area and boost as well, by like 2-3 degrees.

I wonder how can the same tuner do a nutcase map one week and a conservative map the next....?

 

Fuel, compression, setup. All this matters.

 

Thanks, edited my first post with more details

 

Don't know how many tuners are in the VA area, but I've only seen one area mentioned by the OP and no tuner named. Don't want someone getting unjustly bad-mouthed because of a name mixup or premature conclusions.

 

Yup, that looks totally fine, enjoy your ECU!

 

Dimitris, I sent you a PM
