Can anyone help?
I took the 312r to get a custom map done tonight and there were a couple of issues.
1. The rev signal from the PC didn't match the revs on the bike or the dyno by 50%
2. Does an O2 eliminator need fitting to enable the bottom 20% of the mapping to be configured.
It's a PC3 713-410 and the bike is an 09. There was a problem with the 08/09 models due to the polarity being mixed up on the injector connections but this one is fine and the PC is working.
DJ can give you a fix for the 50% rpm, the PC3 you have is for a F41000S which injects every revolution, your 312R has sequential injection which injects every 'other' revolution, hence the 50% pm reading, I needed to do this when I moved my PC3 from a 1000S to a 1000R.
Not 100% sure about the lower 20%, but again DJ should be able to help, best to email the USA as the UK are probably in the IOM

I don't have a Power Commander fitted to my 312R but I recall reading that an O2 eliminator is not compatible with the Euro 3 F4 (which would include the 2009 312R).
To quote Ed Eskew:
You can't just plug in a resistor to trick the ECU with flat lambda signal either (that's why the DynoJet o2 eliminator won't work on Euro 3 Ducati and MV among others, so you can't use the PCIII).
The ECU looks for a varying signal (which is what it sees with proper working o2 sensor) and triggers a fault/fail safe mode if it doesn't see that. There are o2 sensor simulators available from the hot-rod tuners that send a sine wave signal to the ECU. I bought one to test, but got a race ECU before I got around to it. About $50.
Go over to AF1Racing forum site and put up your questions for Micah (in the "What's in the AF1 shop" thread)...I'm sure he can answer all your questions.
