I do not generally recommend copying tables (specifically VE tables) one calibration to the next as there can be substantial differences in the "architecture" in the background of the map.

If you are using a calibration that does not have the latest tables or new features you can use the following procedure to expose these tables 1) make sure you have the latest firmware and software with the update client 2) flash your calibration to the ECM 3) on the PV unit go to the tune manager and Load Current 4) connect to WinPv and retrieve this calibration from the tune manager and all of the latest tables and features will be exposed

So I got a wild hair in my *** last night and decided to throw most of my timing back in. So I pulled up the original map that Jamie sent me and compared it to the map that I was running... I added all of the timing back for everything below 3k RPMs @60kpa - which was only about 10-11 cells. Then I compared each cell 1 by 1 in the 3k 60kpa and beyond block. I took the difference between the original and my current map divided the difference in half and added that to my current table.

I will no doubt have some pinging going on... but let me just say that the performance difference is substantial!!!!! She ran like a beast this morning! I'll be monitoring and adjusting the spark advance to eliminate ping... But I sure have missed my performance. Some cells were up to 10deg off... most were 5-7deg.

Ohhhhhh. AND I figured out why several of us have pinging occurring but it isn't showing in the logs. This is because Knock retard doesn't occur (duh!)... It doesn't occur b/c our tunes are telling it not to. The adaptive spark knock is set to NOT kick in UNTIL 2deg @60kpa 2k rpm, then 4deg @70kpa, 5deg @80kpa, 6deg @90kpa, and 8deg @100kpa. So if I'm understanding how this works correctly (correct me here if I'm wrong, Jamie)... The system will not retard the advance UNLESS there is more than 2deg of knock at 60kpa and certain rpms... Meaning we could be getting up to 1.75deg knock and it won't register in the logs or on the PV b/c knock retard hasn't actually been tripped. I wonder if we can tinker with this to get good data to manipulate our tables with?????

Oh. And can we get an explanation of what these new features actually are, what they really do, etc... The documentation doesn't exist.

Example: I see where I am supposed to select "Accel Enrich" but I do not see that item on the Powervision channel list.
Engine temp is also missing from my menu uinless it is listed as something else.

Is the wording in the instructions different from what appears on the menu screen of the Signals menu?

Is there a help file that explains all the different possible signals?

These are the settings under my DataLog/Signals menu.
B+ -----------------Decl Enl
Set Lambda ---------Set AFR
RPM ----------------ET
Front AFF ----------Front CII
Spark Knock F ------Idle Set
INJ PW F -----------INJ PW R
IAT ----------------MAP
Rear AFF -----------Rear CLI
Spark Knock R ------Eng Run
Advance F ---------Advance R
TP ----------------Twist Pos
VE Front ----------VE New front
VE New Rear ------VE Rear
VSS --------------Warm-up Lambda
Warm-up AFR -----None
None -------------None
-----

In addition to what Jamie said, some of the items are worded a little different when you select them and what they display. For example on your list, ET = Engine Temp.

You don't have to load your stock map back to see the new features. You have to load your current map back from the ECM into the PowerVision. The PV doesn't know what the values are for the new features but your ECM does. When you load current back to the PV, it fills in the fields that are new and were missing from the previous PV file by copying what is in your ECM. Once that is done you have the ability to change those fields.

A question for the tuning gurus around here. I'm having a little trouble in one section of the map that I think with my setup should be good. I'm getting lazy throttle response from 2500 RPM to 3000RPM. The torque is good in this range, I go up hills with very little throttle input at 65+ MPH but when I roll on the throttle the bike just kind of takes it sweet time until I get to 3000RPM then it's starts waking up.
This is a 103 and I am running SE255 cams, there has been head work done.
Once I hit 3k the bike starts to wake up, it really wakes up once I hit 3.5k and is strong to redline. Kind of not what I would expect with the 255 cams. Is it the head work or the tune causing this behavior? I get that the heads are making all the power up top but I wouldn't think it would cause lazy throttle response down low. I find I'm riding the bike between 3k and 3.5k a lot as where I used to ride it between 2.5k and 3k when it was a 96 with 255 cams.

I have Jamie reviewing my map but FM is swamped right now so I thought I would throw it out here to see what other folks think.

What gear, speed, and MAP are you at when it is being sluggish?? Or is it sluggish at 3k across the board?? It could be timing... It could also be the VE tables or.

If you are spiking your MAP (i.e. going from 30kpa to 80+kpa) and the timing is low in the 70-90kpa range you will seem sluggish. Same goes for VE. Of course, it could just be the way the power curve is due to the cams and heads.

I chased an FJR, Phil M from the VR last weekend and I stayed on his rear all day. He even asked why didn't you just pass me. he said "I have never seen anybody ride a Harley like that". The thing is I was chasing him riding the motor between 4-5k. With the 255 cams I would expect to be able to do it lower in the RPM range.

I haven't dug into the timing like you have, but it looks like I may need to. I just tuned until I got to no more changes.
