Hello everyone,

Have a car lying around, a 9n 1.4 BBY engine Polo, thought it would be interesting to just mess around with it a bit.

Found some maps in this file, but I am not able to say for sure if its correct.

Kindly requesting if anyone has any maps for this ecu and conversion factors, please may you share here. Goal is to add a bit more fuel and timing, raise limiter to 6200rpm and maybe pops and bangs for the laughs.

So far I have found this:

Ignition Timing table 1 18x4 or 20x4 - 5BCD0 16bit
Ignition Timing table 2 16x12 - 5BB18 16bit
Ignition Timing table 3 20x12 - 5C272 16bit

Fuel Map (possibly) 20x12 or 24x12 - 57076 16bit

Thanks for any help.

Hello. Any success with definitions on BBY?
