Great stuff RandyN, thanks so much for sharing.
I have a clean and shiny set of ZX14 TB's sitting on the bench waiting to be installed....just waiting for stupid winter to be over, and for my Area-P system to arrive (that I ordered last year...lol). Anyway, patience is a virtue they say;).
I just mentioned this in another thread, but just so you know, the C14 ECU uses two fuel maps. From 0-10% (approx.) the ECU uses an IAP (Idle Air Pressure) map, and from 10-100% the ECU uses the regular TPS fuel map. There isn't a fixed cut off at 10% throttle position...but it will usually be close to that. The throttle body assembly has a MAP sensor that is supplying feedback to the ECU, which the ECU compares with current atmospheric pressure. So, at small throttle openings, there is a differential pressure that the ECU is monitoring. Once the throttle opens past a certain point, there ceases to be any pressure differential, and the ECU switches to the TPS based fuel table map. The point at which the ECU likely changes per the outside conditions...maybe 8% some days, maybe 11% on others, etc.
This may be why you guys are seeing some abruptness or off-idle issues with the ZX14 TB's. The PC5 would be trying to correct a moving target between 0-10% throttle position. Once the ECU settles on the TPS fuel map, the PC5 is golden. I still think the PC5 is the best option for the guys that like to tune their bikes.
Once this hateful winter settles down a bit here, I will be getting out and doing some tuning myself and will get back to you guys with some tuned PC5 maps, and later, a tuned ECU map should anybody want to try it.
Thanks again for sharing your PC5 map and thoughts. A tip of the ball cap to you.
Cheers,
