New exhaust - road tuning -

I do not have a dyno here, and I am a novice at tuning but not a novice at learning.

I want to learn more about how to adjust the parameters of my tune file needed after changing an exhaust system. I'm changing a more free-flowing exhaust back to a more restricted stock exhaust system, and nothing else has been modified on the vehicle.

I understand that I am reducing the airflow to which the current tune was done ( the current tune was done on a dyno with an experienced tuner both steady state and peak state were tuned on the dyno and it took half a day), and therefore with the new system, it ought to be a touch rich, right?

Wideband O2 sensors are installed, and I can record or log while I am riding the bike in a state the software calls autotune, then compare the tune before the exhaust change to the logged file with the new exhaust back in the garage when I'm off the bike. I believe it will make minor changes. But it is not a human, and it is not AI, and I understand the autotune feature doesn't actually "Tune" the vehicle that's my job hence my learning here. Oh I forget to mention it is a 2020 model Softail Harley. Just think of it as a naturally aspirated 2 cylinder engine.

Are the following parameters the only ones I need to adjust: The AFR table and the VE tables, and the timing, which my software calls it spark?

Or might I need to look at anything else?

Appreciate any help

I should add that I am going through the EFI fundamentals and Understand AFR course currently

What engine management is it?

Dynojet power vision

Win PV software and pv 2B flashing/tuning device

If the autotune in the Power Vision works the same way as in PC5, then simply let autotune populate the correction table, subsequently store the changes after riding for quite some distance in all accessible areas of the autotune correction map.

It is good practice to operate the throttle smoothly, especially in part throttle areas, in order to allow autotune sufficient time to apply corrections.

the physical device is connected to the disgnostic plug and set to autotune mode. you then have a choice to take readers from stock narrowband sensors or the power vision target tuner wideband sensors. i then choose wideband. when you start the bike tve device begins taking readings from the wideband sensors. you can see the table updating in real time though when i done it last time i didnt know what i now know about afr and timing tables so i think from memory the table showing is the ve table. it was recomended to do as many different throttle positions as possible and basically ride like I ride. im not sure if you can change or write to any file because it is in closed loop. but at the end of your ride when you stop you can flash the ecu with the new "learned" values. so the current tune is overwritten. you can then copy the new current tune and put that on the software and compare and edit.
