I went on a rolling road today at Triton in Bournemouth.
They specialise in Subaru and Evos.
On my graph the AFR was about 10.6 when the boost starts then levels off at about 11.4.
The rolling road operator said it should be a bit leaner at about 12-12.5 without the big dip in the AFR.
It made the same power as i had when it was mapped at Thorney a year and a half ago. 204.1 BHP at the wheels
242.7BHP at the flywheel
What are other peoples Air fuel ratio?
Maybe my AMM is on its way out. I've never changed it in the 2 and a half years i've had the car.
Any coments please?
