"The Mistress No More"

That would be 5 hp maybe ? Nels has had the new WINPEP 8 upgrade, which we all must get eventually as the hardware is no longer supported.I have my name down for the module. The tech guy here in OZ swears black and blue it will read the same. I will test it. What concerns me is , if it is different , I will have 20 years of data which I cannot compare...

COOL! You know Nels?!?
All I know is what he recently told me and Rob @Claviger.
I was fascinated listening to Nels & Rob talk "tune" which resembles Chinese to me.

@Neville Lush ,
I had my bike dynod at nels using winpep 8, then a week later using winpep 7 at a different shop. Numbers were within what is expected when I was validating my new muffler didnt rob any power, winpep 7 read out right about 10hp higher aka 5%.

Tuneboy set to 7000 RPM limit.

On the graphs:
Winpep 8 dyno reports redline at 6700, 5 pulls personally observed, all cut out at 6700 bouncing off fuel cut.
Winpep 7 dyno reports redline at 7000, 3 pulls personally observed, all cut out at 7000 bouncing off fule cut.

That works out to roughly 5%, which, is right around the HP delta between the two on numerous bikes according to Nels. There were NO changes to the tuneboy tune between the two dynos.

I suspect delta between the two might be based on the RPM readout and not the math algorithm behind the front end. Power commander reports redline occurs at 7100, Triumph ECU reports it right at 7000.

Both dyno operators used the coil wire as a pickup on cylinder 1.

Who knows whats going on, its quite weird tbh. Definitely something they need to sort out though, because if the RPM readout is off, I don't need to explain to you of all people what the impact potential is.

The rpm readout is not off, not from other folk I have talked to, that is also taken off the bike,so one can match it with the bikes tach to check. If you have tuneboy set at 7k I think the rpm limit is different in some gears. I have noticed this on many bikes all on the same dyno. Normally a stock unflashed rocket has higher rpm in the lower gears. When Nels tested your bike, he had yet to receive the latest version of winpep 8. The early versions were released with no other CF adjustment than SAE. NO DIN STD PS etc etc, that would account for 2.4%. I would suggest the win 7 guy used a different gear to test the bike?? The hp calculation on the dyno is from the physics equation Force equals mass x acceleration ( think I remembered that right ) The rpm pick up is only to calculate torque. There is a speed sensor on the dyno, and the rotating mass of the dyno is individually measured in the factory and a code assigned. One can do a plain HP readout with speed on the lower axis and no rpm at all.

With the GOBS of HP you have, likely a small diff - if any!
Can you do a sound clip?
I be curious as @Claviger has CES with a different can and his sounds a lot different than my CES with their can.

As you wish. Something funky going on with my indicators - seems to illuminate at certain revs - maybe relay is vibrating???? @DEcosse ???

 

[Neville Lush]

If you have a PC V on your bike, you may also lose a couple of hundred rpm. Don't ask me why, I do not know, but I have observed this on countless occasions.

Thank you, Tony!
A very cool deep rumble for sure!
Until you raped it a tad, I was thinking hollow cans.
GRATITUDE, M8!

BTW - I watched that 10.7 run again . . . AWESOME!

the gust of wind sent me across the road crossing the centre line

That is severe wind. Yesterday I could feel the gusts slow the bike down - not felt that before ever. For a while I thought it was the bike. Had some shimmying but a long way from a slapper.

See if you can find a contactless (solid state) relay. Never seen that before. That or you've invented a sound activated EMP.

If you be referring to me, Hans, my sequence of events are still accurate whether you first went off road or not.
"Theories" they are not. Limited musings based upon the physical evidence of only 4 pix of your motor, they be.
Roadway evidence would also need to be assessed as well.
Twas merely a preliminary assessment meant to be helpful . . . and was NEVER intended to upset you!
I shall now discontinue further comment.

Who do you think you are? Some kind of motorcycle accident insurance investigator hired by big buck attorneys and doing it for many years. Sheesh!

Finally someone else realizes my dilemma hahaha

Mittzy would you please post your dyno chart for the configuration you have on your signature line 223HP/186TQ ?

And also when you get the new headers dynoed ?
