VAG 1.6 TDi ECU Remapping
Volkswagen, Audi, Seat and Skoda all use the 1.6 TDi engine
CAYA engine code is 75Bhp
CAYB engine code is 90Bhp
CAYC engine code in 102/105Bhp
But there are two things in common – they all have identical engines – same turbo , pistons,crank etc etc – they all also have the same ecu the Siemens PCR2.1 – the only difference is the software – some mapping changes within the ecu data is the only difference – that makes an interesting prospoect for us.
So what happens when we take the lowest power version of this engine – the CAYA version and tune it
For this example we have a Skoda Fabia Monte Carlo version with a best tested dyno figure in stock form of 74.2Bhp and 145lb/ft of torque
after running the car in stock form we have to take the ecu out of the car and unlock it on the bench a bit like unlocking a mobile phone – the ecu then goes back into the car and is started to make sure everything is OK. Then we can proceed with tuning in a conventional OBD manner – I.E. plug our system into the diagnostic port and copy the ecu data – make the necessary changes to the data including torque limiters boost control and limiters etc initially to make it the same as the CAYC and then further tuning from there – finally write this new software to the cars ecu again via the diagnostic port – the whole process taking about 2.5 hours we can then run the car again and just look at the results
Absolutely amazing results with a max at 129.4Bhp and 205lb/ft of torque
That is a massive gain of 55.2Bhp (75% improvement) and 60 lb/ft gain in torque (41%)
I think you can say quite safely that is a decent gain in power
This tuning is available for all VAG group 1.6Tdi engines with codes CAYA, CAYB and CAYC .
The biggest gains are obviously for the CAYA engines as found in :-
