Went to Absolute Pro-formance, John the owner is a Honda guy, vast experience, many trophy's on the wall from drag racing. He spent 4 hours adjusting the car. 17 runs in all I think. He started by giving the car a detailed inspection, most of the specials/engine swaps he sees a total train wrecks, but mine got a passing grade:) A little background, the K24 setup is complicated. There is a fuel and ignition map for each 10 degree of cam angle, 0-50 degrees. Then there is a complete set for VTEC high lift and low lift, a lot of maps. He spent 1/2 hour just smoothing out the maps because they were all over the place. Had to increase the fuel pressure as he were getting a little high on the injector duty cycle. We ended up a 225bhp, we did see a partial run at 227, the car was getting very heat soaked by the end, he is confident it would be 227-229 maybe touch 230 on a fresh run. Great torque curve, just starting to flatten off at the very top end. Took it out for a drive over the weekend and it rips, much better midrange, instant power.

Nice! The complexity of modern engines and ECU control is nothing to sneeze at, but it's great when all of that complication can be harnessed for good.
