G'day Jared, i have race+ installed on my focus & was wondering if using it with a de-resed exhaust will adversly affect the
afr, make it run too lean causing detonation. is the
afr now a fixed number, like 8 for instance or does it still have a range to work in, like 7 - 10.
thanks Ron
the reply......
Hi Ron the
AFR has a targeted lambda of 12 to 1
afr on the ST225 using Race+. This is calculated in fuel weight terms on this vehicle from both a
MAF and MAP system so changing the exhaust shouldn’t make a noticeable difference to the fuelling, if you can get more air in and out, you will get more fuel in and out, hence more power. Good luck J
All the best
