2006 Civic Si
Stock except for Custom Sheet Metal cold-air box and a Greddy SP Cat-Back
V1.04 ST-1 Base maps used to remove the hang + hybrid (CTR) throttle tables were used to fix the soft throttle responce
Dyno is on a Dynapack Dyno, with all pulls done the same day (within 5 hours) - temperature was within 5 degree's on all pulls.
Fourth Gear pulls - corrected to 1:1 in the plots
Big gains under the curve, stupid OE VTEC Surge removed, and with very decent peak gains considering I am using OE cams and header.
Tuning was Done by Sasha At SG Motorsports in Toronto
Stock – I want to note that the ramp up at the end (+8k) is based solely on the Dyno and isn’t the power the engine actually made. The real peak power is where the Yellow cursor is (180whp or so) – Air fuel ratio was 0.80 lambda
SG Rev007 – With less knock sensitivity in the VTEC area and with some cam phasing trimming, no more ignition timing than the COBB map because the ECU was already pulling timing and I was hesitant to make the knock sensitivity much less. Ignition timing was 31-32 degrees throughout most of the high RPM area which is pretty bang on.
So in conclusion we found power from cam timing, meat under the curve from VTEC engagement, and a slightly leaner fuel mixture. Final fuel mixture was 0.88 lambda
They stopped supporting the Honda Civic unit years ago. Meaning that if there is a bug or something isn't working right you will likely have to live with it without a chance of getting the issue solved.
