Audi A4 B5 chassis (2001 A4 AWM 1.8t specifically) factory dash ---- '''CAN IDs and messages''' The needed output is '''ID 0x280 at 100ms intervals''' * with Byte 6 being TPS (0x00 to 0xFA range) * and Bytes 3 & 4 are RPM (little endian: RPML is byte 3, RPMH is byte 4). * other bytes are 0 ? ** Correct (They aren't zero in the OEM ECU, but I don't have all the data, and other bytes being zero allows the tachometer to work fine) ---- According to our knowledge the VAG VW Golf 1.8T (year 2003) (CAN dash messages) is compatible with VAG Audi 1.8T CAN_VARIANT_VAG_2001_A4_AWM_18T that we tested against. * Jason confirms. We just installed a 2000 Golf IV 1.8t over the winter with the Aim -> Audi canbus adapter and the tach works great. Hadn't worked for 15 years since he had a competitor standalone in it prior.
