Very interested in this Scott - any more details?
Thanks Bill,
I've got this sorted now - this feature is so neat, why didn't I enable this earlier! :doh:

What do I need to do to licence the 1BAR MAF RTT operating system (2002 LS1)?
I believe it works like this...
After the fuelling trims have been reset, the PCM needs to re-acquire a reasonably sized set of trim data so that statistically, the trims represent a large enough...
Boys,
I've discovered the reason why my changes to the NBO2 switching points were having no effect...
I was still in the "learning period" following a reset on my fuel trims. :doh: Although...
Take your WB out of the equation by logging a ground free fixed voltage with your HPT interface (see my post in the "w/b problems" thread).
If the EIO Input 1 is logging the wrong voltage try...
Disconnect your WB from the interface and connect your HPT input to a 1.5V dry cell battery (don't use a rechargable for this since they can deliver seriously large currents if you get them shorted)...
I didn't get too detailed at this time - I just wanted a quick test to see if I could introduce a step change in the fuelling so I simply "added" -200mV to B1 & B2 for all air flows.
Thanks 5LE, have just read your thread. I'm a bit puzzled why my mods to my switch points don't seem to be affecting my fuelling since I'm running a Gen3 in the HSV, not Gen4 as you are? :shrug:
...
Thanks Guys - apologies for missing the earlier posts 5LE. I’ve been playing with the NB switch points some more and I can clearly see an offset being introduced when I log the O2 mV, but this...
I’ve recently got my LC-1 installed in addition to my stock NBs (which are still feeding the PCM) but I’m seeing a 0.6 difference between measured WB and Closed Loop Commanded AFR and need some...
