ive recently bought a e46 m-sport coupe 320d on a 05 plate (53000miles)
has anyone installed a tunning chip in a simlar car or the same.
ive been thinking about an easy power upgrade for the car and if this works it will be perfect as its easily removable.
Am i correct in thinking i can install this myself and it plugs directly to the ECU< correct me if im wrong.
do these things work?
i remember a while back people listing transistors on ebay for £5 for petrol engines to fool the the air intake sensor, a friend bought one but just got a engine warning light.
Could anyone reccomend a tuning box or somewhere that sells them near leeds?
one more question, ive heared that the 320d suffers from turbo failure requiring a new engine, does this affect the 2005 facelift models as i dont want to put more stress on the turbo with a tuning box.
Thanks for any help offered
