Apart from getting totally frustrated by these stupid bloody computers...
I said I'd publish results and I will as soon as I can successfully scan and post onto Photobucket!Meanwhile...
I had the Bus dynoed last year. No corrections etc and it registered 158HP. Have to take that with a grain of salt though and really should be ignored for this comparison.
I was booked in to get the Ti Force exhaust change done on the same dyno, and then tuned by the PCIII. However, when I rang to confirm the booking I found he'd taken holidays!!! Bummer.
So via the Powercommander site got onto a different dyno in Perth at Holmes Motorcycles. Cost a bit more but the guys really seemed on top of the game and they did the job. It's a Harley shop, so I had visions of going back and finding the rear wheel poking out of the skip, but no problems. In fact they do a heap of Jap bikes for racing. And they had a Nitro harley being unpacked......
So the first run there can't be compared to the original, and in fact they said they typically get 10Hp less than the guy I had used.
Results show that.
Without the PCIII it returned a peak of 150.58HP and 89.68ft-lb
After using a tank full and extracting $344 they got and almost duplicate curve peaking at 160.32Hp and 96.24 ft-lb.
I'm pretty happy with that.
Then onto the precious air fuel ratio.
Hard to convey that without a graph, but at idle was 12 is now 13.8. But the big difference occurs throughout the rev range. Unmapped, and therefore not too much of a surprise, the exhaust alone (Pair removed) tended to around 14:1 through the major part of the rev range. Mmmmh.
After mapping, they have a nearly flat line at 13:1 from (I'm gusseing) around 4000 to limiter. Under that it ranges between 12.5 and 14.
Once I get it scanned, I'l post it.
The bike feels good, but then again, it felt bloody good anyway!
The test comes in August (1st Track day of the season) and September (Quit Motoplex).
But, without getting into analysis paralysis, the zorst pipes return about 10HP right across the range fro around 3000 upwards. Not bad. <i></i>
