Dan, only the PC-V can be calibrated, so as not to confuse... the PC-V works off of the TPS voltage, so technically it would be good practice to do the PC-V TP reset when you reset the TPS, yes. However, the PC-V has a default to handle a slight variation, but this would be a good thing to document/verify. Thanks for the post on it.draidt said:I have a question on the Autotune throttle calibration, Does the minimum value indicated on the PC when you do a calibration relate to the TPS value ? It appears that on my bike it does. My VDTS value is 4.8 after a reset and my minimum throttle position voltage on the Autotune calibration screen is .480. So my question is after doing a TPS reset via Axione/Navigator or VDTS should not a Throttle Position calibration be done also ? Am I all wet here or stumbled upon something everyone should know and be following ?
