You are referring to an aftermarket calibration list for the SE tuner, while Level 176 can be used among these models there are plenty of other strategy levels utilized across the applications listed, some are considerably different in various ways. Try flashing a 176 Vrod map into a big twin and let us know how well that works.

For anybody keeping score, the PC-V with autotune works fairly decent at keeping the set AFR.

I don't need to flash a Vrod into a BT to know how it will work. I understand the difference between code and calibration. There are letter designators that need to be paid attention to. I suggest reading the TTS manual. It explains this.

........... they can also be applied back to your base map by selecting Map Tools>Auto Tune Tables>Apply Fuel Trims.

What I said isn't absolutely incorrect. You describe exactly what I did. Except that you are saying it runs on these trims and it doesn't need to applied back to the base for the trims to take affect.


I might be wrong on that. I will have to look into a bit more before I say one way or the other.

Are you stating that this is a closed loop system?

If the PC5 is set up with a wideband and the AFR target tables have a reasonable Target AFR in the field, they are all full time closed loop. A zero in the AFR target table forces the system into open loop.

Cool stuff. I have my FZ1 running this way all the time.

The PC-V (5) with the AT kit will take over and seek your target AFR, I'm not sure I would term it as "closed loop" but yes, it will adjust to the target AFR, it's just not controlled by the ECM, it's controlled through the AT module. And it's still only targeting the AFR's from the feedback it's getting from the WB's. It actually does a fair job at doing it.

Really, it is not closed loop as much is it is building a long term fuel trim table on the fly. It builds fairly fast but there are lots of cells to populate. A 20 by 30 Target AFR table generates 600 cells.

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.
