[McLaren720s]

I don’t think developing a solution is a priority for anyone anymore. The problem is that this engine is basically at the end of its cycle and the new M’s with the new S58 engine are due at the end of year/early next year which probably leads tuning companies to question whether they should invest money into a product that will be discontinued within a year or so.

I hope I’m wrong but my advice is that if you really want a tune, find a local shop that can bench flash the ECU and problem solved. They don’t even need to take the ECU out. In theory, any high performance dyno shop should be able to do it.

It’s not as convenient as flashing a map yourself but it’s all we’re probably going to get, unless we get lucky.

Just my 0.2 cents
