Closed Loop Integrator

[HV]

Just some info...I was just doing a PDI on a few 09s... doing Birth Certificates ..noticed that they now have... along with the Adaptive Fuel Value ( Front and Rear ) they also have Closed Loop Integrator Front and Rear ...

HV, thanks for sharing.
Wondering if could you elaborate a bit?
IIRC (could be way off here) but per one of your posts on the old site something about min/max AFV's looked for during PDI??
Something similar on the Closed Loop Integrators now?
Thanks.

It looks a lot like the AFV ... same #s .. IE   front 108       Rear   98 .... some are both 100 Ill look more at one next time I have one hooked up... I know you can reset the AFV ... and the 02s adjust the AFV to re calk the VEs... looks like the Closed Loop Integrator Values are also changed as the 02 readings change ...interesting

Yes, interesting.

Due to the code now being written to the ECMs, I feel it's just a matter of time we'll all be talking Lambda in lieu of AFR for the Harleys. Flex fuel capability on the way too??

HV, the data from the 09 FXSTB, was it read from Digital Tech or DM of the SEST?

Digital Tech ...
I checked a Bagger read out for an 09 ...the #s were like  Front 108.2     Rear 98.8

No the 08 has no option for that item
