Here are the results from the MotoEast tune of my 2009 MX5 6 speed. Wow, I never expected gains this big from just a tune. The car mods are a PPE Engineering Long Tube Header and Midpipe, Goodwin race single muffler with baffle in place, and an AEM CAI legal install for SCCA STR class. That is, the CAI air filter is next to the passenger headlight and the plastic splash shield is in place below. The ONLY DIFFERENCE in the before and after dynos is the MotoEast tune.
The shop printout shows one before pull and two after pulls. The axes have funny values so its hard to read the actual gains. So I took the log printouts and put them into a spreadsheet, averaged the 3 before pulls and 2 after pulls, and charted the results. Wow! Huge torque gains across the board, about 10 lb-ft in the 3500 to 5500 band, and then increasing to 16 lb-ft as the revs climb to redline! And look at the horsepower gain in the chart, which actually grows larger as the revs climb, topping out at 24 hp at redline! This is a wonderful tune result and I'm a very happy guy!
Bottom line is the MotoEast NC2 tune is a winner!
Kudos also to the PPE Engineering Long Tube Header-Midpipe combo, which not only adds torque in the mid-range, but also lets the engine breathe freely all the way up to redline.
I think the car is ready for the SCCA Solo Nationals this September 3rd!
