2nd pot on the TFI??

[billz410]

I'm a little disappointed with all the talk on here about pot. It could be a bad influence to those who are of weak flesh.

I don't know BD. Three other guys I work with have 1600 Nomads. They all run 92 or 93 octane and 2 of the guys, a 2006 (completely stock) and a 2007 (Cobra 2000 processor with Cobra pipes) say theirs don't ping. The other guy with a 2005 says he can get it to ping sometimes but rarely with the Caddman, PCIII and V&H Baggers. Another buddy with a 2001 1500 FI Nomad said his pings rarely too. His 1500 is stock except for V&H Baggers.
When you added your TFI did you reset your TPS back to the original setting? I didn't but if I had I don't think it would have made a difference, if anything it would have probably pinged worse then now. The change I made was so small it is probably insignificant. My bike really runs strong, smoothe and cooler though.

It is possible he has compensated for a vac leak. With out WD-40 testing is left to a plumbers torch not yet lit.. Point and shoot propane at the intake with the engine running to add fuel.

I mean right into the intake too, and then listening for effect.

Then what ever happens, should happen else where at any possible places where a vac leak can be.

If there is a vac leak and it gets compensated for you will drop MPG's like a rock..

I run my 06 1600 on 87 and can not force a ping no matter how bad I lug the gearing down.

It did ping if I was sloppy stock though, and so did my injected 01 1500.

With both bikes and the TFI I got better MPG's.. apx 10 MPG's better on both bikes. Plus I got more power.

My clock settings currently are sort of conservitive, as i ride in a conservitive mannor. Sort of rolling easy chair, with a certain vengance if a tourist sets me off, but I settle right back down.

You g*d**nned fool, yer on thw rong site Bill!

That's over ta' the Gaungiaman site..

(we need more emo-shuns)

Yall are scary me with the car tire, don't think I'm ready for that. Beside running alittle sideways from time to time keeps the ole blood pumping good!!!!!!!!!

Flash.....check out this car tire on The Dragon!! ::)
Just think what it could do on those Yazoo clay based roads in Mississippi!!

I'm more interested in no ping with good performance then gas mileage, my Nomad had a worse then average ping even running 93 and using 3 cans of Seafoam in 10,000 miles. I don't lug the engine, I keep the RPM's usually in the 2,400 range in the higher gears and shift at higher RPM's in the lower gears.

when do you get the pinging? your engine speed of 2400 is quite low if youre going to accelerate from there without changing down, regardless of which gear.
The 1500 nomad produces peak torque at 2800. I would guess the 1600 is the same ??? keep it around 3250 and you should not get any problems.
Anything below that could give you a pinging if you grab a handful whatever gear youre in.

Sunny you made a typo... The 1600 makes about 5,900 RPM before it bounces off the rev limiter.

75% of that is about 4,475 RPM. Maybe you wanted to say 4,800 RPM??

Somewhere between my figurin and your figurin is max torque.

The ping problem is no more than the ecu runs the fuel mix too lean.

Sorry to take time to reply, I'm having trouble working my way around this board ::).

Youre confusing Horse Power with Torque.

The peak horsepower on my 1500 is at 5100 rpm Thats when youre going as fast as youre gonna go.

The Torque peaks at 2,800 rpm. that when you are accelerating as fast as the engine can go.

Any engine speed below 2800 is going to put strain on the engine under acceleration, and therefore increase the pinging.

Remember these are japanese over square engines, designed to be revved, not american long stroke designed to spark at every other street lamp

On my 1600 2450rpm's is 60mph and 2800 rpm's is 70. It sure doesn't seem like I need to downshift at that rpm on the highway..?

If I drove around with the rev's above 3K all the time my mileage will go down the drain!? :(

Take note of the word "accelerate". if youre at 70 on the highway and the speed drifts up to 80 or more, then downshifting is not needed or wanted.

If youre doing that same 70 and you NEED to get past a car or truck in a limited space, then yes, shift to 4th and gun it.

The pistons are huge in these engines, loading them up with low rev acceleration will increase wear on the engine internals.
