Sorry, that wasn't my intention to advertise but to show the policy or lack of policy of DJ.

I tried to make a little nicer, I should have known your pride is a little sore for being called out for being somewhere between rude to damn near slanderous in your first post. You've already changed your story once and I can think of nothing further to add. You can win the internet argument, sleep well and good luck, you need it.

with you there oleboy,
still waiting on data to show hdforum members the difference/similarities of mapping VE with the different dynojet systems (PV-Basic, PV-Pro and PV-TT/Pro)
i know WOC done some comparisons but when I re-read it I couldnt understand the process that was undertaken
a vendor could post this stuff up quite easily I would of thought

I had a bike come in for a time, the customer did a new build, he has the PVV and the AT pro kit. After his build he ran the pro tune numerous times for a,total of 700 miles. After his break in he brought me the bike for a full final tune. I wanted to test the difference between the pro tune and the basic tune so I pulled his current project tuned MAP, then I set it to basic tune and I basic tuned it up to 4,000 RPM'so. I then pulled the new MAP into winpv and compared it to the protuned MAP I started with. The delta changes were quite large IMO. If anyone is interested in can post the screen shots in this thread when I get back to the shop Tues.

I run a PV on both of my bikes. I like it. My Dyna has a mild 113 (124hp/130tq) in it and my SG has a mild 107 in it (116hp/116tq). Both bikes were tuned on a dyno by the builder. They both run great.
I did a fair amount of street VE mapping on the Dyna with the PV before the builds and was wondering which is better if I make some changes in my builds; the AT basic/AT Pro or the TT.
I asked Dan from DJ about mapping all of the VE table(s) using the basic AT at 14.6 (closed loop and open loop). He indicated that I probably should not do that for the open loop portions of my MAP. I asked why then is it okay to map the closed loop portions of my MAP with the wide bands. I think he said that he understood the argument, but really didn't elaborate. Cole indicated in a post that the wide bands (my interpretation) cannot read fast enough to auto tune or control the AFR MAP. Reason I am still asking questions.

I'll try to help make it clearer. I wish I could post the screen shots you are referring to, but I'm out of town right now (I am in Lima, Ohio for the flat track races).
I had a bike come in for a time, the customer did a new build, he has the PVV and the AT pro kit. After his build he ran the pro tune numerous times for a,total of 700 miles. After his break in he brought me the bike for a full final tune.

I had the perfect bike come into the shop today to get tuned. The bike has a Vision, and he also has the auto tune kit on it. The customer ran 700 miles worth of auto tuning using the Auto Tune pro (wide band sensor), he had his rev limiter set at 3000 RPM's. I did the final tune on it and at the end I ran the auto tune basic (stock narrow bands) and here is a screen shot of the front and rear deltas. Make your own conclusions.

Has anyone done a comparison of how good all of the black box variants can tune VE tables, including when used by Internet tuners vs professionals with a dyno and many years of experience, and add in manual tuning from data collected during normal runs (provided the tune is close enough to be able to go for a run)?
Short answer NO!, get it to a Pro!

the PV Autotune Pro has been well regarded by users here at HDforums for many years, now with it linked to TT the whole wide band sensor is being questioned, unless i am misunderstanding the 2 kits, different sensors?

I just had another read of the DJ website...
"Dynojet has evolved the OEM closed-loop, adaptive fuel control system on your Harley to meet the needs of Performance enthusiasts"
Thats closed-loop ...as in runtime, and performance enthusiast ...as in those like Andy that run their bikes outside of the general narrowband range. It ain't being sold as a tuning aid in my book. It doesn't mention anything about tuning!
I just think if you are REALLY concerned about your tune, get it on a dyno so that you can hit more of those cells properly. A diy street tuner is just as likely to miss a pile of cells regardless of what Lambda/AFR the "autotune" process is aiming at ...no?

is holding the bike at 100km/hr, 150km/hr and 200km/hr for 3-5 seconds sufficient with the wide bands?
I have had my bike on dyno for 3 power runs, very happy with results, they are spot on, i use a map provided by a member here, interested to use the PV AT Pro but there seems to be alot of doubt about how good it is now
Thanks
