Visit to ST Powered - RPS13 tuning

A friend's getting his RPS13 tuned by ST Powered's Furugawa-san today and after hearing so many good reviews of his tuning work (better power under the entire curve, durability, EVEN better fuel efficiency), I went down and take a look.

I am no expert at tuning but my understanding is that the more labour intensive and effective way to build the map is to do it up from scratch, one gear at a time, adjusting air fuel ratios and ignition timings a couple of hundreds rpm at a go, until redline is hit. The lazy way is to rev through at a go and using the base map established to backward adjust the numbers. The lazy way is also a good way to blow up your engine inadvertently...

From what I can glean, further Furugawa-san's handiwork is very meticulous, warming up the engine thoroughly before starting, constantly listening for knock through a headphone while tuning. Will post up my friend's dyno chart and a feature of his car when its out of the garage. Its running 256/264 cams, Garrett GT2871r turbo and it should be making 400ps at the crank easily. Stay tuned!


P.S. Spotted an ex Hotstuff cover car. The one and only Wisesquare-kitted S15 in Singapore. Check out the gorgeous carbonfibre front lip and carnards.This car packs a 2.2 Tomei stroker engine. Turbo is out of the car so I guess another turbo is on its way in...
