The ECM doesn't have VE tables.  That is our user interface.

Wurk kept saying this, and I still don't get it. The ECM absolutely does have VE tables. You're modifying them when you program the ECM. These tables are the basis of it's calculations.

[hrdtail78]

I stand correct on that somewhat.  The VE table we see is simplified compared to how the ECM uses it.

[FLTRI]

I think At least one flash tuner mfg should open up ALL tables and constants in the ECM for recalibration by the user.
That way we would have at least one mfg offer all variables adjustments available.
Their tech support may get a bit more lively but that's their job right?

That I can agree with. There are many adjustments that are made to the VE before it ends up as an injector pulse width.

Maybe TTS will accommodate you if you ask nicely.

Already did...a couple years ago and was informed TTS has enough to do just keeping up with elementary tech support from many who refuse to read the manual.

Would prob be a true can of worms.  There is already enough there to fuck stuff up as it is and you add 20 more things to the pot.    Release a new table once every year or two as the population becomes comfortable with whats there is prob better.

The average one time home tune has plenty to work with as is. Pro's on the other hand that do this for a living would likely make use of the bells and whistles. I've always thought it would be nice to view what the AFV is doing in the tune but don't see that happening any time soon. Then again it seems I've finally been able to get a stable closed loop tune for my v rod . Imagine that.

I've finally been able to get a stable closed loop tune for my v rod.

What was the key to getting your vrod to stable closed loop operation?
Vtuned? Where didn't you get good sampling and what did you do to resolve the issues?
Since there are far fewer vrod owners it would be great and valuable info to learn how you corrected your o2 readings.
Thanks,
Bob

The starter map I got with mine is showing a 750 rpm column

You be confusing this bike with the other one. That 120 basically ended up 50/50 open, closed when I traded it in. I just couldn't dial the low end in any other way. I doubt very much even with good sampling the results would not be what the engine would like.   Not a lot of drama with this one. Autotune went as it should and there's no hint of the tune changing. Warmup and idle is good as well. Sampling must be fairly decent on the stock v rod head pipes. Don't think many will have trouble vtuning or autotuning this one with stock head pipes. Right now as it stands it runs better than stock and better than the dealer tuned demo I rode. It popped like a bitch on each decel. I've not heard a single pop through the whole process. Demo bike had the V&H competition pipe on it. Nasty loud, leg burning bitch it was too.

I got the 1k table in the v rod cal also. Equivilent of the 750 for the BT.
Kicker is I don't remember seeing a 1000 table in the green screen during auto tuning and reviewing my base cal to my present one that table has not changed even though I dragged the engine down to that level several times at the start of each run. While my v rod will chug away from a standstill below the 1200 idle rpm it raises the question, if the 750 blocks are missing on the green screen does it even tune this area? Or does it do it in the background within the ecm but not visible? Pretty sure my autotune screen started at 1200 with the v rod cal. Now I need to take another look, with glasses this time.

Ron- if you look at the closed loop integrator values, it will give an idea of how close your ve's are and how much things are going to drift over time. PV has this choice on the menu. It won't show real time afv but it  should help somewhat

[hdmanillac]

You can also look at VE and New VE with the gauge.

[HV]

After tuning mine...I run two of the gauges set on CLI for front and Rear ...you can monitor the map as your riding this way...100% most of the time... it may go to 96% or 105% but very seldom ...

Got signals set up to view other things at the moment. I will revisit the CLI and see what they area showing. Viewing other things shows a lot of weird stuff. Engine temp on a v rod being liquid cooled and having a thermostat it does not operate like a car at a fixed temp. It will range from 180s to 205 depending on air temp. There's a hell of a range between start temp of the thermostat open to full open and it's design likely causes this. My bike has low kpa. 25 at idle and 4k cruise at 100kph is only 38 @ 10% tps. Seeing all this going on in real time is cool. Oil temp closely follows engine temps also and have only seen 200 once.

On my map it's there too.  Just didn't see it collecting any hits there while auto tuning nor did any of the VE's change in the actual new map.  Pretty much why I asked what's going on in the 750 row.  I suppose just drop them down a point or two until someone says otherwise.

[runamuck]

not all the .pvt maps I am looking at for my bike have the speedo calibration option in Tune Option..what's up with that..is there a way to add that line to a map file.

Hi,
I already had an AT100 that I used on 2 previous Dynas with PCV, both with good results. All I had to purchase was the longer leads and I could use it with the Powervision, so rather than leave it on a shelf its now installed, looks like its reading the widebands, in guages, dynojet, reading Lamda 1 and 2 shows a reading. Theres doesnt seem to be a lot of instructions about using Autotune Pro so please can anyone give me a start.
Are there any settings I need to change to run with the widebands ?
Do I just use it in Autotune then go back to the narrowbands when I have a good map ? or can I leave them in all the time ?
When I get a good map, if I go back to the factory lamdas will it use the map made with the widebands ?
And any other tips would be great.
Thanks for any help.
Jeff

[joe_lyons]

Use the widebands to tune and when done replace with stock sensors.

[hdmanillac]

All the manuals are here http://www.dynojet.com/Powervision/powervision-software-firmware-downloads.aspx?ProdType=Power%20Vision

when you do that are you going back and making sure the closed loop cells are in sync with the stock sensors? 

[joe_lyons]

If using the auto tune feature it only alters afr table when enabled once your done tuning you disable the feature and your afr table goes back to the way it was.
