When it prompts me on my power vision to reset trip level and scale or cap what exactly does they mean?

and what should I do?

 

I would cap it, then export it to a tune slot. After that load that tune into the ECM then auto tune it again and do the same process. If you scale it Dynojet software will automatically change the cubic inch of the motor in the program because of the high VE tables ( over 127.5) that auto tune is trying to change. I myself would keep cap and do what I first said..

Couple of questions though first, Is this the Bike in your Sig? If so with all that work, you didn't Dyno tune it??

You should always state year model and build specs to start a thread like this so most can offer up the proper Advice...

 

it was dyno tuned but they couldn’t get the rough first gear taken out advised me to get wide band sensors

I had it tuned good got lots of hits in auto tune then scaled the map and exported it and remapped and now it’s running crappy again in first gear sputters and choppy

 

I had the same issue with my build on my 2013 in my Sig. Your system is doing all it can do.. The ECM see's it rich and is now leaning it out.. You need to understand that when you do an auto tune with the Auto Tune Basic that it sets the entire AFR map to 14.6 because your narrow band sensors can only read AFR's from 14.3-14.9:1.. Then the ECM tries to calculate your necessary VE's and air flow based on MAP/kpa readings and adjusts everything back up to a leaner setting that only the Narrow band sensors can read. You will need to reload the original dyno tune..

I asked you to state your build and again you did not fully describe it.. What cam do you have because that will make the most difference in the way your motor runs.. How familiar are your with Harley's and do you understand high performance builds and how they are supposed to run??

So what cam?

 

2009 street bob with 107” mega sphere kit

dave Mackie 575l cam
big sucker 2 intake
d&d fat cat

like I said I did a good auto tune and had it running mint lots of hits almost the entire screen was red from hits but then scaled that map and it’s running crappy again in first gear.

No I’m not expert in engines

 

Are you saying When you initially take off in the lower RPMs in first gear and then after that everything's fine like from takeoff to say 2,200 RPM it's rough?

 

yes

 

Sounds like your going to have to increase your AFR's in the range it's running rough..

 

My 107/Tman 590 build was tuned on a dyno by hrdtail78 @ C&S Speed Shop and the displacement is 117. Way too many cells would've capped at 127.5 making the VE cells inaccurate. Actually even the base map Jamie at FM made specifically for my build when I bought the PV was set as 117cu.in and I STILL have some cells at or near 127.5.
​​​​​But then my heads flow real well...

Agreed, this is done to make the ECM think that the motor is bigger because of all the air that it is moving.. my 103 it's set to a 107, but that will not cause the OP's issue from idle to 2200 rpm.. You should also make sure your Map Tooth IVC is 30 and IVO is 8.. These will be the proper setting for your DM cam.. Also like if said earlier. Bring your low end AFR's to at least 13.7-13.6.. Are you running open loop or closed loop?
