That's why I got rid of mine. I already had a slow 01 Miata, so I wasn't going to have a car payment on another slow car.

Meh, really I'm just being a baby. Once I get another job lined up, the ACE header + Delicious tuning E85 tune they've done for that header will = another 20-25whp over where I'm at now.

The OTS OFT tunes are pretty conservative.

<p>How come companies can provide a boxed tune for something like a header for subaru's, when Miata's can sometimes barely idle on base tunes?</p>

Because miata's throw away the MAF sensor with ECU upgrades, so they can not directly measure airflow as a MAF engine can.

<p>Is it because our MAF doesn't have enough range?</p>

Yeah, it maxes out at some point and becomes a useless restriction. Its somewhere around however much air it takes to make 180~hp IIRC but don't take my word for it. The data is buried somewhere here on the forum.

Yes and no. For a NA car it has plenty of range. For a very low boost setup, they work, BEGI has sold turbo kits that kept the MAF meter for example. For high powered cars they will max out.

For me I'm going to install a GM MAF sensor, and setup a Arduino to do a lookup table conversion to output the same signal the miata MAF would, but with extended range. Raw GM signal to MS3 for fuel calcs, simulated miata MAF signal to factory ECU for emmissions purposes.

Any idea what whp you are at now? What killed it for me was really the torque dip. Revving it out was fine, but the speed limits in my town are ridculously slow (45 mph on open highway for several miles) so low to midrange torque is way more important for driving around town here.

Maybe 180-185whp? Based on what people are reporting stock on E85?

Tune + E85 negates most of the torque dip.

So on current setup I'm at 16.5mpg all city driving and lots of WOT pulls. Not bad imo. Forester averaged 18, so we'll see how this tank goes (trying to drive it normal, but just can't stay away from boost )
