DYNOJET: TT AT vs PV Basic AT
I have tuned a bunch of 5's with AT-100, but it is with the shops AT-100. So none of them have left here with the AT kit still attached.
I didn't know it made adjustments to the 5 map on the fly. (Before trims were applied) I thought it was only after you accepted and applied the trims. If this is so. I was wrong in my description up top and I am here to correct/ admit my mistake.

All I saw at the link was a bunch of links to scatter plot data. I am not that well versed on reading that sort or thing or a tuning expert such as yourself.
Could you just spell it out for me? Again, I'm just curious
if the systems are not that different in VE mapping, why is it advantageous to use the AT Pro/TT and wide bands? If I map VE with the narrow bands at 14.6 and then change my AFR table to 14.1 or 13.2, are my VE numbers going to change? I don't get it. The AT Basic maps them all at 14.6, the AT Pro maps them all at 13.0. How does the VE change when you adjust the AFR table?
I may be wrong, but I thought the whole idea of VE mapping was as follows:
You set the AFR table to a target figure, you adjust the VE figures (RPM and KPA) until you get your AFR target reading in the pipes. Once that is done, you can adjust the AFR to whatever you like. Why would it matter whether I use the AT basic/AT Pro or the TT?
I just don't see the difference (narrow band versus wide bands). I mean regardless of what system you use to measure or build the VE tables, the VE of the cylinders is going to be the same with both - right?
Thanks.

OK her is a Dyno tuned Bike at the top half of the screen and at the bottom is my Target Tune bike. Look at the Desired AFR compared to the AFR on the bottom of each plot. Notice how well the the Target Tune bike holds AFR as it rolls down the road. Both graphs are real close to 400 sec worth of data.

Hard data would be the data log as it was collected out of the bike. Not data put into a screen shot that has different scaling.
When ever anybody asks about their calibration. It is also best to post the calibration so people that want to answer can get the most info out before answering questions.
When somebody ask about how their bike runs. People want to see a log file. Not a screen shot. Take a look at this thread for example. Notice a log is asked for and not just a screen shot?

Wasn't this thread about comparing 2 Dynojet products?
Why is Andy comparing a Dynojet product to a dyno tuned (with what and by whom?) bike?
We're looking for TT AT vs PV Basic AT not anything else right?

Here is a well tuned Sporty tuned with Autotune Basic and narrow bands and then installed a Dynojet Pro setup to log and see how we did. The bike was running open loop fueling at the time of this low as we had o2 eliminators on the 02 sensor plugs.
