Hondata

I'm using the "big boost map", B16supercharger.bin, as advertised and it's working very well. The car and mods used to generate this tune seems to be identical to mine. However, as I'm at about 6000ft elevation I'm running rich so I'm tuning the fuel maps.

My question is do I need to tune the ignition maps, and if I do how much horsepower difference could it make. I don't have experience on the dyno and tuning ignition requires this so I don't want to sweat over minimal gains.

THANKS AGAIN

Start with the fuel maps then move on to the ignition maps. If you hear detonation then you have too much timing and should back it off a few degrees. YOu will be surprised by how much advance the engines like at part throttle.
