Hi,
I had the opportunity to reverse engineer the official Diagbox telemetry protocol that is used on my 208 GTi BPS.
Using any OBD2 scantool based on the ELM327 ic, now I can read any of the data in realtime, as does the official Diagbox (e.g. measured MAF and requested MAF, measured MAP and requested MAP, oil pressure, turbo wastegate opening ratio, etc…)
If anyone is interested, I can share some info about that…
