If my map (open loop portion) was auto tuned with the AT basic and then I set the AFR table back to 12.8/13.0. Will this not work?

I answered your question the best I know how over on the other thread.

Let's keep this civil, there's some good info in here and i'd hate to see this get locked. It's not worth anybody getting "banned" over.

I FedEx'd a wide band kit to oleboy. We spoke and he seams very eager to do this test, after speaking with him I am confident he will give us a good test and I am as eager as anybody for the results. I have run similar tests myself but in an effort to not "appear" biased I, for the most part, keep the results to myself. I'm very curious to see if oleboy comes to the same conclusions as I do.

Andy

What level of calibration is your sportster running on?

You want to know some facts Andy? They didn't change anything for the sportster. It is the same as the other big twins as far as the closed loop for that level of calibration.

When did the PC5 become capable of running closed loop?

I removed the obvious.

Stating again... good debate is fine but when it gets under your skin back away and post later.

I see that DJ marketing and verbiage got another. This isn't a closed loop system or even an auto tune. You collect data and down load the trims out of the PCM in one area of the map and then you must apply them to another area of the map and download that map in order for them to take affect. It doesn't automatically do this for you or does it control anything with a closed loop feed back.

Editing to say that this is wrong. The PC5 does make adjustments to the PC5 calibration with out accepting and applying them to the PC5 calibration. I was not aware that it did do this. I apologize for giving out wrong information, and hope this hasn't lead anybody astray.

PC-V Auto Tune is a closed loop system, Power Commander is a piggyback controller and does use not closed loop logic native to the Delphi ECM it uses the PC-V module/processor and closed loop with its own wideband O2 controller. The PC-V map has an AFR table which controls the commanded AF; Auto Tune maintains this mixure with live correction. You have about 250 break points/cells (per cylinder) for your targets and this configuration can be found in the PC software tree view menu on the left under Primary Module>Auto Tune>Target AFR. As you ride the Auto Tune populates trims and it makes corrections in real time, these trim can be be monitored in your device under Primary Module>Auto Tune>Trims, they can also be applied back to your base map by selecting Map Tools>Auto Tune Tables>Apply Fuel Trims. Auto Tune (closed loop) is configurable by min run time, engine temp, and you can set the min/max enrichement/enleanment %, PC-V also has an input for a switch that allows you to turn Auto Tune on/off or it can be configured to switch between multiple maps both of which can be done on the fly. Hope this info helps
