Well I bought a Dinan Engine chip for my 93 318i, it worked great, it changes the rev limit, takes away the gov. and inriches the fule intake. When I bought my SC the two of them did not get along too well so I had to take it out after only having it in for a few months. I realize that this applys to a very small select few of you but if anyone with a 93 318 wants to buy a Dinan engine chip let me know, i'll give you a fair price on it. I do not belive the chip will work with a 94, only 93's but if you are intrested let me know
