Dyno tuning

[SpazOnaR3]

I do wish there was a tuner around that tuned with tune ECU but there isn't.

It's a shame you're not a little closer to SV... I have a little private dyno for developing our racebikes and I don't mind using ECU-specific software to tune things. The Harley guys are crazy about that stuff... I've probably had my hands in 6 different motorcycle flashing packages and another half dozen stand alone types. I can understand why big shops don't want to do it, though... it is very, very time consuming to do a full tune with flashing software alone even when you are familiar with the software... and it takes time to navigate & learn the new ones. I spend an average of 6 hours doing custom flash tunes on V-twins with individual cylinder mapping, and that's without developing timing maps (kinda overkill for air-cooled street motors in Arizona... most customers would rather have a little safety cushion rather than 1%-3% more power).

When I had the Victory tuned it took him 3.5 hours to tune each cylinder. Lower RPM lower throttle positions he went 14:1 and as the RPM raised and the throttle position increased he richened it until 60-100% throttle he went 13.5:1. That 106 cammed Vic motor put our 118hp 116tq, not bad for an air cooled V-Twin. That tuner went out of business so now I'm going to this guy. CLICK. Jeff has tuned Bonneville record holders and he's tuned two of my friends bikes so I trust him. He's also tuned many R3's so that's good also.

Sounds like a solid fellow... I wonder if I've seen him out at Elmo or Bonneville? I'm terrible with names, but I can usual place a face. It's a shame he doesn't want to dive into the ECU flashing, but I totally understand why.

Those victory numbers are nice. I've done a number of 88" -> 96"+ Harley motors lately... that's about on par HP-wise with what they make... I think my friends 106 made 120ish, but it was suffering from a serious lack of head/intake flow over 3K rpm, IMHO. I tend to run 'em a little richer than that... I find that they feel a little smoother that way, though best power is usually in that 12.5 -> 13.5 sweet spot. Most modern motors make about the same torque per cc... it's just where in the RPM they make it that makes for cool looking dyno sheets.

My Vic with OEM heads and throttle body didn't run out of flow it was still building power up to redline.

There are all kinds of folks who have posted their dyno results -- you just have to look.

Mickey Cohen's got me to 160 with RamAir, tors, and a PCV.
Roughly 35mpg combined.

Wait, 160 rwhp? I took my '18 Roadster to him with a similar setup except K&N's instead of Ramair and only get 139 with 146 lb/ ft. He even installed the DP crossover on mine. I feel like I got screwed...

Yeah, he seemed surprised too. My curve was basically just a climb up and then it just stayed pretty much flat until the end. Unfortunately I got distracted buying a horn cover from him and did not take a picture.

How long ago did Mickey tune your bike? What year is it? Are you in SoCal?

I'd have to take a look at my statements to let you know. It's definitely less than a year though. 6 months tops? Bike is a 07 standard. Yeah, socal.
