5 volts is a reference voltage from the ecu and a few components use that voltage like tps, tip over ect
The ecu will set a code if it a lot lower and maybe if it is a lot higher. Kinda like saying a cup of coffee is full when it is not at the prime. So no problem with 4.98
#1 is ground
#2 is the voltage being sent to ecu
#3 is the map reference voltage Approx 5 volts
Are you familiar with PC V , pressure configuration ? Cause following the steps of the YouTube PC demo video I got stuck after typing in the pressure table voltage value 0.250 : "0.250 is not a valid floatingpoint value " So something is not ok for this configuration voltage value. But what did went wrong ?

I put a PC V on mine and it lost about 10 miles per gal and worked worse. So I took it off and sold it cheap.
Not sure what you mean by floating point value but the map send a reference voltage 0 to 5 volts to ecm so not understanding how you could set a voltage. I understand how the ecu works but i am a long way from programming an ecu. Or the pcv

"floating point value', that's what PC V is warning for when did click 'ok' in the configuration set up. I don't know what this should mean either. Point is that I had to remove the stock mapsensor when I had installed the sc at the time. With the PC V and Autotune, the bike was then air/fuel ratio tuned for throttle openings only. That worked reasonably well. However, without mapsensor it is rather a hell of a job getting the engine 100% pressure/ fuelratio fine tuned. So now with the Bosch map sensor incl its PC pti wiring harness, that fine tuning should gonna work 100%. In the PC V map tools there is also the possibility to set up a ‘pressure/voltage' table value configuration . btw. the PC V is manipulating the ecu signals. The PC V module also has an analogue input, any sensor of 0-5 volts can be connected here, based on this sensor, you can have a separate fuel table included, this could be e.g. boost or temperature.
