Greetings to all you can call me Dazza I have been a member for a while of your forum, I have searched your forum and have been enthralled with the knowledge base, I own a 1996 E36 323I auto also a 1985 E30 323I manual fully option with factory lowered suspension. I have joined your forum for some assistance and also to be of assistance if I can. I am a mechanic and have done all my own repairs on my 2 BMW's as well as others. I have just completed the M50 manifold swap and am very happy with the extra horses up top, but have noticed quite a drop in torque in the lower RPM range. I have done a lot of research on this and found not a lot of help in regards to the E36 323I for software options to remap the ECU without spending a couple of grand I have a friend in Adelaide who is willing to dyno my BMW if I can find the software to do-it and this is where I need some assistance if I can ask. I know this may appear to be rude at such a time being a new guy to your forum I hope you will forgive me I look forward to any help.
