TA23, Your oil being black doesn't suggest running rich, it being thin and smelling like petrol would indicate that. Also if your oil level rises on the dipstick between changes. Being black just means your engine could benefit from a good clean on the inside. Turbocharged cars are bloody hard on the oil and carbon deposits in the oil are just something that comes with it. They are detergent oils and cleaning oils around if you want to give it a good flush This may sound harsh but your car is in tune or out of tune. Half a tune sounds like a half baked idea to me. As for running a Map sensor over the AFM. No you won't make more power or use less fuel ! Your car may well make more power and use less fuel when he is finished but that will be because it is tuned better not because it is map sensored. The advantage of a MAP based tune is that it will basically self calibrate to changes in your intake. It measures Manifold pressure so if you change intercoolers, get a boost leek, or improve your pipework the MAP sensor will adjust your tune to suit. It also means you can run a BOV that vents to atmosphere without upsetting the AFR. If its pinging and you can here it... Its bad ! Kinda sounds like tiny hammers in your engine.... beating the crap out of your pistons ! Ask KECOOP about it LOL Hope that helps, [Report message to a moderator]
