What did Hondata find when they analyzed the RSX Type-S ECU?
– It runs very rich at high rpm – It has conservative ignition timing, tuned for low emission at high mileage. – It is VERY sensitive to the knock sensor (could explain dyno power differences in stock Type-S engines) – Once tuned, there is more power, yet the same or better emission, and better economy. Basics: What makes power? – The motor is really an air pump – Put in as much air as possible – Add proper fuel and ignite it at the right time – Make sure exhaust doesnt restrict – Simple as that! The iVTEC system of the Type-S is a combination of VTEC and VTC. VTEC basically creates one camshaft profile for good low end drivability, torque and fuel economy, and a second more aggressive wild camshaft profile for high end power (The Hondata K-Series ECU Manager calls those low speed and high speed). VTC rotates the camshaft by a total of 50 degrees which results in different valve opening overlaps by changing the relative timing between the intake and exhaust valves. Both VTC and VTEC us
