Pinging & DPV
« on: September 29, 2017, 09:36:02 AM »
Since last firmware upgrade of my DPV (august 2017), I've got lot of pinging on both cyl and especially on rear cyl in cal areas that are normally excluded from ping detection and during cruising phases of running with every parameters stable (TP, MAP, RPM...). For example 2000rpm-50kPa.

Is it possible that the DPV detects false signals ?

I've changed the spark plugs, SE type, with same result.

Some friends of mine using DPV have the same issue.

I tried to send you a map to look at and try.  The PM wouldn't work.  I will attach and see if this will work. You PM is full is why I couldn't send it to you.

Note firmware updates have no bearing on the actual tune. While updates may expose more definitions or new features within the product, it does not change the tune itself

This afternoon, I've tried the cal listed above. Still lot of knock detection on the rear cyl.

Otherwise, I've tried to modify Knock Control parameters on my cal:

- Knock Control Minimum MAP from 50 to 60kPa
- Knock Control Minimum RPM from 800 1750rpm.
- Table Spark Adjust By Air Temp to make it start at 60kPa and not 50kPa.

No change of other parameters.

And knock detection (false detection, not heard) is gone.

Change your plug wires..  Buy a new set and just install them temporarily. Go do another log and see if it goes away. If so, you can remove your tank and install them as they should be.

I tuned two bikes doing this. Wires fixed them both.
I feel the need... for twisties with speed.

 "The local dyno guy" says SE plugs and wires cause false knock sensing.... any truth to either?

I only use stock oem wires. A local guy was having issues with his bike and I told him to do the basics first and replace the plugs and wires and use stock ones. Later found out his PC3 was bad. So he brought his bike over for me to tune it and he said HD had no stock wires in stock and he bought the SE ones. I tuned his bike with no problems.

So I really don't know if the SE ones can cause issues or not but they worked OK in this case.  I'd still stick with stock though.

You must be a glass half full kind of guy. I see this as an advantage of the ion sensing, it lets you know when your wires are on the way out.

This afternoon I've changed the spark plugs. I get rid of SE ones and put original ones. I've also changed the plug wires for brand new original ones too. And spark knock is gone.

Thanks all for your help.

Personally, I think Ion Sensing is too damn flakey and even HD saw the light now. Even better if they got rid of that damn Delphi .

Not sure about all that seeing the light stuff but I do know that they were set on the two plugs per cylinder and I do not know of any to make the Ion sensing work with dual plugs.

True enough. Dual plug would double the trouble.
