I had my 2009 1125 CR dyno tuned today. The bike has a stock 2010 engine with 3,000 miles on it, Barker's exhaust, EBR Barker ECM, and K&N filter. Tuned with a PCV by Paul at Blais Cycles in Dania, Florida. The EBR Barker tuned ECM had a great tune but I have always felt that a tune could be further optimized with a custom dyno tune on a particular bike with local fuel, etc. While the bike shows an average improvement of 5HP and 5 lbs of TQ, the cripsness of the throttle response, acceleration, and smoothness of part throttle cruising all improved substantially. I tried to upload the dyno graphs but the maximum dimensions were exceeded and I don't know how to correct it. If a moderator or anyone else is interested in seeing the HP and TQ graphs, I can email the graphs for posting. My email address is mgelberd@aol.com Mort | ||

Thanks Noobuell-Hope the dyno graphs can be viewed with the link below: /imagelink(http://mortbike.imgur.com/all/ Mort | ||

A few more notes on the PCV tune to add to my previous post above. The red graph shows the improvements after the tune vs the blue graph which is the EBR Barker Race ECM tune( an excellent tune in and of itself by the way). The 02 sensors stay disconnected after the PCV install(plugs were installed) and the bike remains in full open loop operation. The dyno tune took about 6 hours and cost $340 and the PCV was $295 from Dennis Kirk. I downloaded a ZERO map from the Dynojet website into my PCV so that the tuner could just trim fuel levels a bit on top of the excellent EBR tune. The ignition timing in the EBR ECM was perfect and left unchanged. As you can see, the bike was just a bit lean in a few areas. Previously, there was a bit of "stumble" at part throttle low gear cruising in town, that is gone now and cruising at any rpm/gear is just buttery smooth. I still can't get over how much better the bike accelerates and how much sharper the throttle response is! Mort | ||

Wow, 6 hours! He needs to do more Power Commanders, average about 3 hours now. | ||

And to add to Mort's impressions, the low speed drivability on our 1125 bike after tuning with the PC-V was so much improved it was amazing--- and this was on top of an EBR ecm. | ||

Here you go. Your slash was the wrong direction and you can't link to albums, only individual images.   | ||

Thanks for posting the graphs properly Noobuell. The peak numbers are not worth much in comparison to other folks runs on other dynos but the shape of the torque curve and the before and after graphs on the same dyno, same day, same operator tell the story of the PCV tune. Jim is absolutely correct in that there was a dramatic improvement in low speed driveability following the PCV tune. No more stumbling at slight throttle openings in low gears and smoothness/decreased vibration at all rpm's is much improved along with much better acceleration any time you twist the throttle at any rpm or in any gear. If I had it all to do over, I would still buy the EBR ECM for all the features it offers, the excellent initial tune, and ignition timing settings. It's just that even the best tune on one bike can never be as good on another person's bike, especially in another location with different fuel, weather, elevation, etc. Jim- In regards to the 6 hours for the tune: Blais Cycle's primary business is dyno tuning with Power Commanders and they do at least 7-8 a week. On inline fours, they get it done in approx 3 hours off of a single O2 sensor. In the case of the 1125 Buell, he essentially did two maps, one for each cylinder using front and then rear wideband 02 bungs and it took him a while to get his wide band 02 sensor hooked up to the front cylinder, so yes three hours if he tuned one cylinder and used that map for both cylinders but he insists on an individual tune on each cylinder for optimal results. He did the same on my highly modified Harley XR1200(with 1250 kit, etc) with great results. Mort | ||

the PCV on top of an EBR ECM! excellent report. THX | ||

Mortbike, thanks for posting your results. You have proven what I have suspected about running a PCV on top of the EBR race ecm. Excellent running characteristics. |
