Auto tuning an existing non canned map
Tried this over in the ignition/tuning section so thought Id try here. Likely overthinking but
I have the dyno tune file from a gracious member with the identical build to mine exc for the exhaust (Im s&s powertune his is jackpot 2-1 road&track) its already in my my pv can I just run some auto tune sessions to hopefully correct/adjust for the exhaust? If it even needs it . I ask because his dyno tune would have been done on the treadmill with wide band sensors and my pv auto tune would be based on narrow.
Ive had mine dyno tuned but not sure shes where she should be and the member is very happy with his and Id like to give it try.
Not going back to my tuner cuz she is running fine. Its more just curiosity because his results were 10% better with a similar upgrade exc exhaust which I guess may account for the 10%
Any advice or thoughts welcome.
Thanx

Exhaust plays a huge part in the results of a build and the tune. It's right up there with cams. You would be further ahead auto tuning(did I just say that ?) YOUR dyno tune than his if you think there's room for improvement. Unless your tuner doesn't have a clue how tune.
The difference in your builds is more than you think.
Besides the obvious(exhaust) do your heads flow the same? Is your compression the same?
Then there's timing which will be be different.

They are both 2010 touring bikes with stock 96 motors. I assumed the heads and compression would be similar and they both have the same upgrades.

Gunner makes some valid points, why not start by comparing the basic tables of each map in WinPV, where are they different ? by how much are they different? Compare VE, AFR and timing tables to start with, Then move on to other things, PE, DE, warm up fuel all the secondary things, read up on what they do and how they play their part in the total equation. Some tuners dial in the VE, change up the main fuel a bit, check for spark knock and call it a day. A good tune comes from somebody that takes the time to check all the details. There is no way I would just load somebody else's tune without looking at it first. And always remember that what a bike did on the dyno that day isn't necessarily what it will due on a dyno today

When PV runs an auto to you chose the tune you want to use. But when PV loads to run the Auto tune it loads a generic map.
It records then when you export it makes changes to the map you exported it to. It may take a few runs but it should work.
Another option is search DYNOjet downloads for one close to your setup.
Make sure you have a copy of the Map saved on computer just in case you mess it up. Yea it happens.
If the MAP you want to use is not from a power vision. No idea how to make it work.

Gonna leave well enough alone. In checking the FM database they get almost the exact same results with two similar setups using the 222s which are on par with the 48s. (85hp 101tq) They also had an 09 with JP headers and bub7s that did 94-105 so there’s the difference exhaust makes . But I’m happy where I’m at.
thanks for everyone’s input.
