Probably an E99 or E93, no we don't support them.

No plans at this stage, only if the ECM anti-tuning security is bypassed like the L5P is now then we would consider it......But we aren't working on trying to do that ourselves.

I didn’t know they put the lockdown on all their ecm’s. Thought it was just a diesel thing.

Unfortunately it applies to every new ECM & TCM from 2018 and up unless the vehicle has stuck with an earlier ECM for some reason.
The L5P Diesel just happened to be the first one in 2017.

I hear all sorts of rumours too about 2021 or 2022 models will be locked down even further than what they've deployed now.
