Boss, I haven't heard this before. Can you confirm?
Also, why would we assume that the encryption on the S55 engine is going to be any less sophisticated than that for the S63tu engine? My prediction is still no real CAN piggybacks or ECU remaps for many years to come for both the M5/6 and M3/4. |
There is a thread over at the M5 boards about a PP delimit where we also discussed the ACS delimit.
The ACS is the only delimiter on the F1x M5/6 that has been independently verified. Last year the German magazine Auto Bild Sportscars did a high speed run at Nardo in Italy where lots of tuners had been invited. ACS brought their M6 GC and did a verified 320km/h on stock tires and 328km/h on taller tires.
They had expected to go 340km/h on stock tires since they had cracked the speed limiter but lost power at 320km/h... They later discovered a second speed limiter in the transmission, set at 320km/h.
This may (17th-18th) the same magazine is arranging a new top speed event at the Contidrom in Germany. ACS will be there and do a new run with their M6 GC! Suspect they have cracked the transmission limiter as well...
