hey people.
i have a fault on my focus rs mk1,with bluefin "chip"
the car runs perfectly...but ive had the mil warning light pop up..and the car goes into limp mode
and ive read the fault codes..and it was related to the oxygen senor not sensing difference before and after the "cat" which isnt there..
so i got the mil exterminator..from pumaspeed
got it mounted today..and luckily,the mil warning light stays off.
buuut...when hitting high boost....peaking...when letting of the throttle..and trying to floor it,,it seems like its gone into limp mode again...but no mil warning light
connected the bluefin..read the fault codes..and it says "p 0234" which is "engine overboost condition"
so now my question....anyone experienced this..and why does it do this..when its on bluefin setting...i though it was supposed to be able to run the high boost without throwing a fault code
suggestions please
