I developed this technology for zx-12 sportbike riders but have found that it is popular with ZX-12 sprint car owners on the east coast. So I thought I would spread the word.

The OEM Denso ECU used by the ZX-12 motor is reprogrammable. You can change the ignition maps, Alpha-N and Speed Density fuel maps, remove the 186mph speed limiter and change the stock RPM Limiter.

I understand that last one is a big deal to you guys as you spend so much time up against the limiter and that an extra 800 rpm coming out of the corner can be a big deal.

This is not the crystal mod where you overclock the ECU to raise the RPM to 105% (and mess up the injection by 5%) This is reprogramming the number inside the stock ECU the limits the fuel and ignition.

For information on having me do this to your ECU for a reasonable fee.
