2013 Scion FR-S: BRZEdit Reflash Tuning By MP Tuning

March 13, 2013

2013 Scion FR-S

That's Mitch Pederson of MP Tuning getting busy with the BRZEdit ECU reflashing software on our long-term 2013 Scion FR-S. This is significant, as BRZEdit clears a huge hurdle in successfully implementing forced induction.

But we're taking one step at a time. Currently we're (by that I mean Mitch) just exploring the software, getting a feel for its capabilities, and confirming that it works as advertised. Don't want to rush into this, that's for sure.

So far, so good. BRZEdit impresses. Its interface is intuitive and appears to have been developed by people who understand engine tuning. Many, many maps are at the tuner's disposal, and it's fun to watch Mitch fully immerse himself into them. As you can see, he gets into a trancelike state.

There's not much to report yet, but we'll have more to share once we nail down some dyno time.

    Cool! I was actually about to say in another post that I didn't understand why you guys had not done this, but I decided to check the FR-S page just in case. Glad I don't have to remove my foot from my mouth. Anyway, that looks like some pretty good software.

    Let me get this straight, you guys paid to have a almost stock car tuned BEFORE you add forced induction? That is a waste of money.

    You saw 173/143 stock...with just a tune, assuming this guy knows what he's will see 180-182 hp and 148-149 torque with these improvements pretty much consistent from 2500-7000. No help with the dip. There will be no serious improvements until they go FI. Early results with FI are showing around 300 whp/220 lb./ft torque with around 8 lb. of boost. Car has too high a compression ratio to run a lot of boost, and it's not a particularly strong block design. Stock clutch starts slipping at 220 lb./ft. and any more than around 15 minutes of track use results in pretty serious overheating. Going FI with this car will be interesting and fairly expensive. They already have about $5,300 in wheels, tires and exhaust - turbo/SC with tuning will be around $7k, new clutch say $1,500 incl. install, cooling system mods say $800 incl. install. With sundries, sorting and incl. tax, when they have finished with FI they will be within shouting distance of $45,000 incl. original vehicle cost.

    One journalist commented that was not a very "special" engine, which is similar to what I read from the Miata engine being not a particularly sporting piece by itself. Is that your impression? How does it compare now compare to hallowed 2-litre v-tec engines from Honda?
