I'm after advice from anyone else who has tried this. I have an early Nothelle converted 3B, basicly consisting of an RS2 turbo with a modified RS2 exhaust manifold and modified ECU. Since I bought the car I have been running with a standard MAF and K&N cone filter. I have always had problems with the MAF, ie;- it needs cleaning with contact cleaner for every tank of fuel otherwise it will start to run like bag of shXt and get progressively worse intil the point where it's not drivable. However for the first 200 miles after cleaning it's a missile
Anyway I have bought an RS2 MAF and airbox along with some other bits with the intention of using them when I do my major rebuild later this year.
This evening after getting pised off with cleaning the MAF all the time I thought I'd just stick the RS2 airbox and MAF on and see how it would run. I wasn't expecting the result!! the car is transformed and now running better than ever particularly in respect of smoothness . It doesn't feel quite as responsive and snappy at the bottom end but the mid and upper mid range is outstanding. The last 1500 rpm doesn't feel quite right. Quite hard to put my finger on what it is but I guess it just needs setting up properly.
Basicly I'm curiously of the different specs of MAF, as I wasn't expecting to be able to just whack a ABY/AAN or an ADU MAF on a 3B without having to change a few other bits and pieces and tweaking the ECU. I'm sure it will still benifit from a proper remap but that's not going to happen until after I have done everything else I'm planning.
Will be interesting to see how the already poor fuel consumption is affected, but don't really care about that
