tephra v7 and 1byte rpm logging with evoscan

I'm using evoscan 2.9 and see an option for 1byte load but no option for 1byte rpm logging. We're spinning the engine to 9000rpm on the stock ecu/maf combo and need to see something beyond the 7969 cap.

does anyone know why that's missing from evoscan and how to add it back in? I thought I had it before in an older version but I may have been using v5 and 2byte RPM which apparently is no longer supported in v7.

I've only seen 2byte rpm. I don't think I've ever seen a 1byte rpm multiplier in the ecuflash xml.. tephra may know.

You can still log 2-byte RPM with V7; just need to add it to the MUT table. That's the only way I can log up to 9k.
