I just had an email from Steve Mullen at Nightrider regarding LC-1 kits (Wide Band O2 sensors) with SERt and here is his comment:
With SERT, you have the tool you need to do your tuning. While the LC-1's
can add a level of sophistication to the tuning, with just a Stage 1 type
engine, the LC-1's tend to be overkill.
The LC-1's can be programmed to any closed loop AFR that you want. I choose
13.5:1 because it is a good compromise between cooling the bike, gas mileage
and power.

That's why I'm interested in something that auto-maintains a decent AFR, but still allows the HD ECM to do its stuff. I thought the TMAT was the answer to my prayers, but because it fails to use the ION sensor, timing is an issue. Wideband I can live without if I can get to a decent AFR, which is automatically maintained, but allows the stock ECM (assisted by the SERT) to do its thang. No decent tuners anywhere near here, so I have to live with the canned map, hence the desire for auto-adjustment of the AFR. So, I have high hopes for the Headquarters Pro Tuner, but they are still waiting for them to come into stock....
