New full Termi install impressions

Totally agree with that ^; but the thread you mentioned is a dud with all the bitching that went on.

Nearly every thread turns into a bitch session in some way

Key points from that thread:

"Sound isn't my reason - I'm hopeful to be getting better midrange feel and response out of the Full system - just like when I went with the full system on the 1198.. It transformed the 30 to 40 1/4 to 1/2 throttle ride-ability. Though that may have been more to do with getting rid of the exhaust (butterfly) valve."

Mostly proven true. With the full system, it feels like I'm running extra rich around 6 - 7k RPM. Coming out of a corner grabbing full throttle in that range bogs the motor down just a bit prior to the 8K surge in power. Outside of that everywhere else feels much better.

"Question from that thread: i understand that if you get the termi,s fitted then it gets remapped, i would expect this to be remapped with the baffles still fitted, so if i then took the baffles out would it require another remap?"

Answer:
No, not at all. It is a standard map for all bikes so is not a "perfect" tune for any bike but rather a median on the standard deviation bell cure from a sampling of bikes. Once we get over the idea of perfection and understand that close enough is good enough, its easy to understand that the standard map will still be fine with the DB Killers in or out. The Db killers only add a little more back pressure than the open cans, more notable at mid to higher RPMs. The additional back pressure will slightly "richen" the fuel mixture, but not to the point that you would notice a real difference. (unless your bike was already on the richer edges of the SD)

If you didn't know:

Addition of Back Pressure without remapping will increase the fuel to air mixture ratio (richen). In moderation, this can add more torque and response down but less top end power. The engine will also run slightly "cooler" due to unburnt fuel. Going too rich will bog down the engine and make it feel sluggish.

Subtraction of back pressure without remapping will decrease the fuel to air mixture ratio (Lean out). Running lean will give you more top end power and higher engine running temperature. In tuning term, lean is mean, but you don't want to go too lean least bad things will happen But that will never be the case for the standard tuning our race exhaust mapping.. they'll always be on the safe side. (usually richer than the Stock map)

Most manufactures tune a little lean to help pass emissions - Lean = cleaner burn and less work for the catalytic converter.

Picture this if you will - you have a Stock system which is trying to meet noise regulations so is creating back pressure which will in turn richen the fuel mixture. Now Ducati has to back off the fuel to lean out the mixture to to meet EU3 emission standards. - Hence why with the race system and remap it feels like you've "opened up" the engine - quite literally.


"If you are looking to modify the stock exhaust or go with a idfferent aftermarket than Termi, give it a few months. I'm sure someone like Houston Superbikes | Aprilia Dealer | Ducati Specialist | No.1 Parts, Sales, & Service will offer a "key up map" our re-flash service for the Panigale soon."

Sounds Like Austin Racing is going this route now.
