Put a Power Commander V on our 1125 today. Bike has stock airbox and muffler. Dynoed at 131.4 before. It was lean everywhere. Dynoed after at 141.9. and is so much smoother. Going to do a map with the pipes we have here --a D&D, a Jardine,and a Drummer. Will have them available for a price when done. | ||

Is this the same bike from the shootout that baselined at 122 hp? | ||
| Mountainstorm |
I am not even going to dissect how unrealistic those numbers are for a stock bike regardless of map. | ||
| Kicka666 |
Dyno & correction factor of the dyno will give different readings. | ||
| Firemanjim |
Really, why? What was your bike? And not same bike as exhaust shootout.And it is not the first number that counts anyway it is the difference you are looking for. 10+ HP on stock piped bike. And bike is from EBR, was their bike for fuel mapping for Euro bikes, has updated injectors etc.The same bike made 142 with a EBR ECM, ran mid 10's at the drags.

Did it have the stock exhaust with the ebr ecm at 142hp? And if so, what advantage with the PCV if keeping the stock exhaust? | ||
| Firemanjim |
I wanted to see what difference a PC V would make so put stock ECM back on and started tuning.First with stock exhaust,then add a K&N, then I have 3 slip-ons to try. Stock the bike was not smooth and with PC-V mapped it runs so much better and smoother,especially down low. | ||
| Firemanjim |
K&N installed and ran it, no real difference.Pipes next. | ||

"I am not even going to dissect how unrealistic those numbers are for a stock bike regardless of map." ?????????  | ||
| D_adams |
Want another one to play with? | ||
| Firemanjim |
Sure. Did the D&D,actually made a couple HP less.And LOUD!!!! Have not finished up lower end tuning so cannot compare numbers down low yet. | ||

I got a PC-V a while ago. Can you explain why they want the O2 sensors to be disconnected? Will it hurt anything if I leave them connected? | ||
| Rodrob |
With the O2 sensors connected, the ECM will try to "correct" the changes you make with the PC. | ||
| Firemanjim |
What Rob said. If we knew exactly where the learned fuel areas were we could tune around them like we do on the earlier XB's. We just tune to 14.7 in that area. James, what pipe is on your bike? | ||
| Stirz007 |
"With the O2 sensors connected, the ECM will try to "correct" the changes you make with the PC." +1 As an example, the race harness does not include provisions for the O2 Sensors. The ECM will go to base map at each power up and will use the barometric pressure sensor to adjust A/F values (to a degree). For my rig, it will always run rich at altitude as the base map is set up for sea level conditions. | ||

You could try an fmf when I get back to CA. | ||

I have had the PCV and dual o2 auto set up on my bike for a while and it runs great. | ||
| Firemanjim |
All finished with the D&D map, not bad, it finally made a couple more HP than the stocker---though I need to go back and redo front cylinder on stocker as I was tuning it when AFR was at 90.OOPS. Next will be a Jardine. | ||
| Kusib |
My bike is stock except for a K&N filter and the PC-V... I got the PC-v for cheap.. thats why I have it before an exhaust..lol | ||
| Firemanjim |
Jardine map done, 141 HP. Amazing how smooth these bikes are when mapped----  Kusib, no reason you cannot get yours running better with the PC-V. Let me finish the stock map and you can try it out. | ||
| Kusib |
Cool.. That would be greatly appreciated.. | ||
| Firemanjim |
Redid map for stock pipe with AFV set proper on front and so far the stock muffler is making the most HP of the 3 I have done. Darn those Buell engineers! (Message edited by firemanjim on December 12, 2011) | ||
| Firemanjim |
The Drummer is looking real good so far,up 4 HP on the current champ--the stocker----still more tuning to finish. | ||
| Blownharley |
Jim, I bought a used PCV because i think my 1125 runs really rough at the lower rpms. Did you get it much better than the map supplied with the PCV for stock exhaust and air filter? | ||
| Easyrider |
he Jim, Any dynoshoots to post | ||
| Firemanjim |
Blown, have not looked at any of the canned maps as yet but will do that. Can only say I got the bike very smooth. Easy,major pain to get our dyno graphs to format I can post,and no dang time. | ||
| Buellmojo |
This is some good information. The stock exhaust finally gets a fair shot at the noise makers. I am not at all surprised by the results. | ||
| Firemanjim |
Blown, looked at the PC-V maps on Dynojet site. All theirs appear to be the same for front and rear,and much different than the one I ended up with.I had widebands in both cylinders so could tailor them individually. I pulled fuel in most of the upper ranges of TP where they added it. Buellmojo----they pay those engineers alot of money to design the exhaust on our bikes. I did a back to back swap on my last Triumph Sprint with stock can and the Triumph "off-road" one and made no difference in HP, so the stocker stayed on. | ||
| Smit3833 |
Can't you get the auto-tune for PC-V? That seems like the optimal way to tune the bike for each pipe, then just save the map and sell it for a few bucks... | ||
| Kusib |
Finally got my PCV installed after dealing with HD and a bad regulator/rectifier and I uploaded Firemanjim's Map for Stock pipe. WOW what a difference. the Bike is sooo much smoother everywhere. And Pulls like a frieght train. I can literally cruise at any rpm and haven't had a hickup at all. I am use to a studder when riding V-twins when in the low RPM's My TL1000r has that same issue. THis map corrected it all!!! |
