RoundV21 (2021-08-05 15:55:08)

Round V21 looks like AFreshTiny Round v2, and has the same hardware peripherals (4 strong lowside NFET outputs, multiple analog inputs, RPM/wheelspeed input and activation inputs, communication port, etc... ) , with more than double memory (flash and SRAM) for new firmware features in the future.

The round V21 can be recognized by:

LSU4.9 nernst and pump and heater hardware, EGT, voltage out, boost, PWM0, PWM4 output etc... are tested from VemsTune. There is currently no other firmware released for this HW, for downgrade or upgrade (so only LSU4.9 is supported).

VemsTune "update ini from web" is needed
