I am wondering if anyone else would like to share their tuning results regarding the Screamin Eagle Pro Race Tuner.
I recently got fed up with how hot my bike was running, and noticed as soon as the weather warmed up and I started wearing my half helmet, I could hear the dreaded marbles rattling around the heads (pinging/knocking) at 2750 - 3000 rpm in 6th gear. That's my normal cruising speed so it's annoying as hell! And forget about it if I got caught in stop & go traffic, the engine felt like a blast furnace!
A little back story to make a long post longer: The bike is a 2011, 103 Ultra. Modifications made were the addition of the Jackpot 2-1-2 header and the K&N breather/filter kit. Stock mufflers. Local H-D franchise suggested I buy the SEPRT VCI module and have them "Smart Tune" the bike to set it up correctly. So I did that. They stopped the popping on deceleration, so I thought they did a correct tune. NOT! Turns out they just used a canned flash and let it go at that! They don't have a dyno, so no real "tuning" happened.
I purchased the software and the cable kit along with the training DVD and wound up uploading the tune the dealer did from the VCI. Looking over it, I noticed two glaring errors. 1) My Heat Management was left OFF! 2) my rev limit was set to 7000 rpm! WTF? No wonder the engine felt like a blast furnace in traffic jams!
Using the tables from the VCI tune-up, I decreased the AFR by 0.3 (increasing fuel) in the rev range I had problems with, and I retarded the timing front & rear by 2 degrees in the 2500 - 3000 rpm range. I made sure the Heat Management was turned ON, and reduced my rev limit to 6000 rpm, and also made sure automatic compression release was activated.
Results: Operating oil temperature has dropped more than 20 degrees, from as high as 269 degrees before to a high so far of 244 degrees. I check the oil temp when I get off the bike using my digital oil dipstick. My fuel consumption seems to be the same, still averaging 43 to 45 mpg on a tank. Only two tanks since the change. The bike also starts from a standing start better, seat of pants dyno says its pulling stronger. Got stuck in another traffic jam and the engine started running rough, I figured that must be the rear cylinder cutting out for heat management, so that is working too!
That's all I've got for now, anyone who would like to share, please do.
