Standard closed-loop map on 1996 RT/10

[ViperPict]

Fairly basic question - how is the closed-loop map managed on a 1996 RT/10. I know that later cars have four narrow-band lambdas but how about the 'Gen 1.5'? Thanks in advance.

IIRC the rear two are only for the emissions to check the cats are working

UK vipers didn't even have rear 02's

I know the M25 is a closed loop? Well it is according to my Map?

Hamish, sorry I missed your calls. Lambda trims at all rpm ranges (except WOT), and also the MAP sensor imput is quite authoritive, and air temp. I've always used the EASE software (via OBDII port) to watch the fuel, timing, lambda values, its quite user friendly and you can pick what you want to focus on and log, just not as good as MoTec.

Thanks Nad. Yeah, I plan to monitor adaptation across the map using an OBDII scan tool and use the tuning software I have to minimise that in the narrow-band region of the map. That's the plan anyway!
