Thoughts? It would be cheaper and easier to invest in a good aftermarket (high end) scan tool or a used DRB-III.
The OT-1 and most lower end scan tools that provide generic-only OBD-II data ride on the slower J1850 bus and as you've seen are limited on bandwidth, but you can pull all those parameters in addition to all the manufacturer-specific parameters over the SCI bus with higher end scan tools which can log much faster.
As to swapping to CAN there's a lot of stuff besides just the powertrain controller that rides on the current PCI bus in the Neon. The SKIS (Sentry Key), instrument cluster, and even the radio just to name a few. In addition to swapping all those components and since this is in the SCT section, you'd also have to verify they'll support the newer PT turbo NGC-4 computer you're looking to use. Theoretically possible? Maybe, but it's going to be an expensive and complex nightmare. If you're mostly interested in data logging and have an XCal2 we can hope SCT gets around to getting that support finalized. It will ride the faster SCI bus and you shouldn't have any bandwidth or logging speed issues you have like on the OT-1. While that SCT Live Link logging would be great it would be even better if they offered a LogWorks plug-in like
some of the other aftermarket tuning options.
