Zero cells indeed just pass through whatever happens stock. That doesn't mean it's best for what you are trying to do. This may just mean that whoever did the map just didn't bother with those speed-load combinations. Follow procedure regardless of this.

HELP! - Terrible Fuel Efficiency on SV650s w Power Commander
- Thread starter Marcfolch
- Start date
Thanks for the response!
So on your map does that mean you have alot of repetitive -ve numbers? Like in rows of -ve numbers?
Reason I'm asking so much is I don't want my bike stall in the middle of the road.
What's on my map for my bike is of little relevance to what your bike is going to need. I have two bikes with PowerCommanders and what was necessary to do on one bike to make it work right, was not what was necessary to do on the other bike to make that one run right. You have to do what's needed in order to make yours work.
Went to Hindle today to get my son's bike tuned. His bike has a PCV and was rich through the entire range. Dropping the afr from 12:1 to 13:1 also bumped the power on the bike. Had to add a second map to the bike to ensure his bike doesn't surpass the max allowed hp once he's running the liquid gold I'm required to pay for at CSBK. Hindle was worth the drive out. Great family run place, really nice people.
Great time for thread revival! I need to see what this Power Commander 5 is all about and what’s possible on my bike.
Thanks!
Thanks!
I have become aware of a new wrinkle when it comes to PowerCommanders. It seems that they got in hot water from the EPA in the USA for manufacturing a device that could be used to circumvent emission control equipment, and the new ones are nerfed to limit how much adjustment can be made in the speed and load regions that affect the EPA test procedure (mostly part load).
Supposedly there's a way for authorised tuners to overrule this, and if you can prove to PowerCommander that you don't live in the USA, there's a way to overrule this.

The stock ECU can be reflashed (for now), although in my case, there is no spare I/O that could be used for quickshifters and the like.
All of this aftermarket stuff is contingent on the US EPA or CARB not sticking their fingers into the mix. Theoretically the emission-control anti-tampering stuff isn't supposed to apply to race vehicles, but the companies that make the hardware to do all that can't survive on selling only to track-only customers. EPA has been slowly plugging away at automotive aftermarket suppliers for the last decade or two.
Minor digging finds that PowerCommander initially got in some EPA/CARB hot water as early as 2007, with round two in 2022 leading to the PC5 being discontinued and replaced with the CARB-approved (and nerfed) PC6.
In the last few years, EPA has been wielding a big stick as there were a ridiculous number of companies selling parts "for off-road use only" to applications where they were exclusively on-road (for instance tuning for diesel trucks where there may be a few thousand in the country used exclusively off-road but each company had sold tens of thousands of boxes). Same with PC5. How many hundreds of thousands did they sell? How many bikes are track only in the US? As a protection from liability, the tuner could ask for a race license. At least that shows they did some due diligence that the product was being used on the track (but nothing is stopping you from buying a pc5 for your fleet even though only one sees the track).

It's pretty hard to convince the EPA that a million coal rolling Dodge RAM 1500 Diesels are competing offroad. Same with HDs, VStars, and Vulcans.
How many Km/s on the Bike? What about a new Fuel Filter? Have you tried that?
