AFR value & ECU Prodrive MY99
Hi, I want to check for the Air Fuel meter values of your Subarus impreza GC8. Currently I have the ECU AE800 and replace it with a Prodrive kit MY99 which is an AE801 (according to Ecuexplorer) which is more aggressive in Fuel and boost. The doubt arises that the AFR value is 10 at most 10.2 but generally in any journey it is maintained there. I do not know if that is good or it is too "Rich" I would like to tell me what values are those that handle these ECUs that are original without any modification.
I have exhaust in 3 inches full decat. TD04 turbo, Higher volume Aftermarket IC Bar&plate. and raise the pressure of Boost by shrinking the Pill Restrictor to 120 to 115. Raising the pressure slightly not much more to avoid problems.
Original air BOX & Kyn panel filter. Silicone Y-Pipe Hoses, and silicone Inlet.
