Default 24 byte 98 PCM question

I'm soon to get my wideband in the mail and I'm ready to hook it up but just realized that my ECU's limited by the 24 byte thing. What the hell is non-essential for wideband tuning (hptuners pro)?

Are there any bits of data that I can stop logging that won't be critical in tuning? I know I'll be using the MAF in freq to find the error % in regards to Lambda, like Greg Banish's Summit Racing DVD outlines.

Will anything be needing MPH? What else can I kill?

Your wideband doesn't use up a channel with the HPT Pro setup, as it comes in the EIO interface. Aside from making some custom PIDs (like the commanded vs. actual error % for lambda as Greg shows on the DVD) you shouldn't need to pare off anything; I know I still log MPH in my car, and still have 1-2 channels available while scanning.
