WRX Stage 1 Tune By MAPerformance | 2015-2020 Subaru WRX Accessport OTS MAP

Good price, fast delivery, great costumer service (as with every transaction I’ve had with MAP thus far), and the tune works well for my 17 WRX. Thank you Eric D.

love this tune. the Cobb stage 1 is huge improvement over stock but this MAP is even better. I feel more torque & its smoother than cobb. This is the ECU tune the car shouldve came with.

Had been running the Cobb stage 1 OTS tune and decided to give the maperformance OTS tune a try after reading reviews. Definitely worth it, in my opinion car has much better response with this tune.

To start off, MAP's Stage 1 tune could be all you'll ever need (although longterm, I think protune is a good decision, even on a stock car). Everyone knows the stock throttle mapping has an overly aggressive tip in, making the car very lurchy and difficult to drive smoothly. MAP's tune smooths this out, giving you a much more linear throttle response. It takes a few days to get used to - initially the car will seem sluggish since you're used to barely breathing on the throttle to get moving. I'm running the 91 oct HTN revision., and get 92 oct at the pump. Rev hang? I have a 2020, so rev hang wasn't a big issue to begin with, but MAP's tune further reduces rev hang to the point that while not completely eliminated, it never impedes shifting. The performance gains are there too. Stock, the car pulled fine in 2nd gear, but had the power dip at 4.5k rpm, and completely lost steam above about 5.5-6k. MAP's tune isn't going to blow you away with how much harder it pulls. Instead, it's the powerband that impresses. I can now shift at 6.4k rpm (it tapers off a tiny bit near redline), and the power dip is gone. It just keeps building/pulling. In all, I would guess your 1/4 mile trap speeds should improve by 1-2 mph. Even if you didn't buy your Accessport from MAP, 1-2 mph for $75? No brainer. Knock? I've had literally one reading of -1.41 feedback which is within margin of error (read: normal), and it was while coasting. Every car is a little different, especially with OTS tunes, but my car loves MAP's Stage 1 tune so far. MPG is unchanged in normal driving conditions. This tune is a no brainer as Step 1 on your engine performance journey. This really is how the car should have come from the factory, no question. I mean that. Read the reviews here, on Nasioc, ClubWRX, Reddit, and you'll find the vast majority of people running this tune are enjoying it without drama.

I was having a weird problem with my wrx where it was hesitating to go kinda like a misfire, thought it was the spark plugs or maybe the coil pack changed all that out still happening, bought the stage 1 tune come to find out it was the Cobb ots stage 1 tune that was the problem. Put the maperformance tune and and bam! Car runs and hits boost like a dream. Can’t thank maperformance enough.
