About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 2004 Audi 80 2.8 V6 Coupe (128 kW, 174 hp), for its Hitachi ECU with part number 8A0906266A and ECU number MMS-200C. Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on this engine refines the ignition timing and the fuelling across the rev range; on an engine without a turbo the gain is modest, the throttle answers sooner.
The file is listed for the 128 kW, 174 hp version of the Audi 80 2.8 V6 Coupe. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
For this calibration of the Audi 80 2.8 V6 Coupe we sell the original and Stage 1. Stage 1 comes in two versions, tuned from different reads of this software. Every file downloads straight after payment.
Read the Hitachi ECU with your usual tool and keep the read: compare its hardware and software numbers with the ones on this page before you write the file.
Catalyst off, DTC off and speed limiter (Vmax) off can be added to this file on request, for off-road and competition use: send us your read through our file service and our engineers add them (any file £50, from £30 in packs).
Part number 8A0906266A is the car maker's number for this ECU. ECU number MMS-200C is how this Hitachi ECU identifies itself.
