h22a S100 dyno graph

Post by ridewhencan »

This graph is the product of three tuning sessions. The first was street tuning since the dyno was not available but the next two sessions were on a dyno. The tuning dyno didn't have torque or rpm so I went and ran it on another dyno and this is what I got.

WTF, I had a smoother power curve with my VAFC. You might say that's pretty good power for a H22a but this is the build.

The iacv was not functioning for the first two sessions but I wouldn't think it would cause the VTEC dip. This was quite a let down since the dyno I was tuned on said the motor was making 257. Here it is.

The green line is a nitrous pull. The middle line is the one that recorded 257. There is no vtec dip since I didn't drop out of vtec on the shift. My own wide band recorded similar a/f ratios as the later Dynojet. It doesn't seem like it would be that hard to tune it out but apparently it is.[/url]
