Hi i am selling for a friend a 3b ecu which has a 'Genuine polar performance chip in it. This will suit all early wrx's that are fitted with a 4 plug ecu.This is simply one of the cheapest ways of improving the performance of your td05 equipped WRX.This is simply a plug and go item and the advantages over the Z4 ecu are:

1.Boost level raised to 1.1 bar 16 psi (0.9 bar 12.7 psi on Z4)
2.Fuelling and timing adjusted to suit UK super unleaded fuels (97 RON)
3.Fuel cutoff level raised to 18psi (15.65 on Z4)
4.Speed limiter removed
No soldering or fitting required just plug and go £120

 

Would ya take £100 posted can pay paypal.
