*** Update! ***
As per my previous post about getting lower than expected HP/TQ #'s and leaner than expected A/F ratio...
I did a small roadtrip from Calgary, Alberta, Canada and decided to head over to 2WDW to get a custom tune for my bike and perhaps see what was up with my local dyno numbers and I learned a few things from Nels...who is quite honestly a genuinely awesome guy.
He made time to get me in on short notice even though he was prepping for a race day event the next day.
My local dyno results were low (see previous post) because of the simple fact I was running sport touring tires , Michelin PR4's, which are arguably the best sport touring tire you can get...but you need to make sure they are HOT when doing a dyno run.
You can see he started by doing a typical dyno on the bike, and sure enough it came in at 137HP,68TQ to the wheels...exactly what my local dyno run showed!
Then, by doing
nothing more than taking a few extra minutes to properly heat up the rear tire, he did the run again, and sure enough just under 145HP/75TQ!!
Holy bawls...Nels showed me this in the first dyno pic.
Nels explained, if ST tires are cold, they will slip at higher RPMs, giving you a lower peak number; which is a typical mistake made by a lot of dyno shops.
He then took his time to do custom mapping for my bike and the result was 148HP/77TQ.
I'm sure with a bit more time we could have hit "150" but honestly for me that wasn't really a priority.
My other concern of the bike running lean (see my original dyno thread pic) were also alleviated, as now it showed it running at optimal A/F.
Nels gave a reasonable explanation that dyno operators need to properly calibrate their o2 sensors every day. My local dyno shop just finished moving to a new building and I'm fairly sure I was the first person on their dyno in at least 3 months, so it's very possible theirs wasn't properly calibrated.
Quick lessons learned and tips:
-If running ST tires, make sure the tires are hot before doing the actual dyno pull
-Make sure the rear bike is firmly tied down tightly with straps both sides
-lower your rear tire pressure to ~30 psi to ensure full patch contact with dyno (we didn't do this)
-If doing an A/F with your dyno pull, ask when it was last calibrated
Review of tune with 1000 miles to get back home.
1) ALL of the throttle on/off jerkiness is gone...completely. I was hopeful Nels could improve it a bit, but now it's butter smooth without exaggeration. I run in STD mode mostly, but even A & B mode were considerably better.
2) The bike pulls even harder (much) and more linearly than with just the mail-in flash. I cannot describe how good and confidence inspiring it feels now. The flash alone definitely added more power but felt a bit rough around the edges. now with a custom tune for my bike it's night and day different.
3) I thought I was a pretty good and experienced biker, but now this bike now scares the crap out of me
