I’m sorry if this has been covered before but I couldn’t find the right map doing a forum search.

I’ve got a stock ’08 with a PCIII and Z-Bomb that are not on the bike at the moment. I’m assuming that PC won’t be issuing a map for this combination since it’s in direct competition with them. So… Can anyone confirm that I can manually adjust the default PCIII map for a stock bike (not the zero map) and get a reasonable result? The fuel map appears to be leaner than stock on the 100% column at 9,500 rpm and above. If I zero the fuel adjustment on the 100% column from 9,500 rpm onward that should theoretically put me back to what the stock bike would be putting out. That means with the Z-Bomb installed the bike will be putting out the stock 85% fuel setting between 85-100% throttle and 9,500-13,000 rpm, which is supposedly about OK. Has anyone done it this way? I’m thinking of even going +1. Opinions?

I would say use map M132-001 for Stock exhaust, stock air filter.

Then go into the map and add +9 to the values of the cells at 100% from 10,500-13,500. This is what DynoJet says to do for the IRC, so I would venture to guess that would be a good starting point for the Z-Bomb. You may want to contact brads955 about it.

I would add the fuel at a lower RPM, starting at 9000 to 13,500, just at 100% throttle. Just because the timing gains only occur at 10,500 doesn't mean the bike isn't running leaner below that. These recommendations hold true for either the zbomb or IRC.

Zeroing those 100% settings would probably work OK too. There is a bit of leeway in the fuel settings, a little richer is safe, and the generic +9% adjustment is safe. Zeroing it out is OK, you just run a little leaner.

Yeah, I figured you should add fuel lower. In DynoJet's instructions for the IRC it states that things will start to lean out at 9500, but it doesn't say to add anything until 10,500. I thought that was odd.

Thanks a bunch, guys. If I understand you right you're suggesting that I should add +9% to the value that's already in the map (i.e. the 100% throttle 9,000 rpm value of -6 would become +3), rather than pegging all the values at a straight +9?

wouldn't all those changes be covered if you had a custom map done?
Yes, they would, but it's not that important to me to spend the time, effort and money to have it done with the PCIII default map available. Especially since I probably spend less than 0.25% of my time at 100% throttle above 9,000 rpm. Most of my riding is commuting and I've mellowed quite a bit since the last sport bike I had.

I wasn't asking what is important to you. simply asking if a custom tune covered all those changes

Yes, that is correct.
