THe reason your chip is giving you fits, is because you probably have EWS. Meaning you must clip that lead under the hood. I'm sure you can find a diagram somewhere with a quick search, if not, PM me.

As for brakes and rotors, it's pretty simple, there is a DIY in the FAQ section. I wouldn't change them if your car is equiped with the floating rotors that are usually found on that model. They are excellent, and unless your car is gonna see inordinate amount of track time, are sufficient.

DOn't install the lower temp thermostat. Have a good friend with a 95' M3 as well, and had bad luck with it. He knows more about these cars (has owned SEVERAL M cars for years, and builds drag cars) and would undoubtedly take his opinion over anyone I know.

Hi thanks for the reply... but i still dont quite get what u mean by EWS problem... When i installed the dinan chip it just cranks but will not start, but once i push the car and with engaged gear then release gear the car starts (jump start) it will work fine.

as for the brakes what is floating rotors? and why is it better than the UUC big brake kit with 4 pistons 355mm front and 320mm rear.?

and as for the lower thermostat why?

oh by the way i also got a metal impelar water pump.

thanks again.

EWS is a security feature that must be disabled with most custom proms. If you pop the hood, there are two circular harness taps next to the fuse box. There is a solid green wire that must be clipped. I'm positive it's green, and I think it's #6. That will solve your problem.

Floating rotors were offered on the earlier E36 M3's, and are one of BMW's best designs. They provide for excellent heat disapation, and can be pushed to great limits. Your big brake kit is better, but it's just not worth the expenditure. If it's not your $$$, well then bonus for you. BTW, four piston calipers aren't really better than two piston calipers, at least the engineers at ///M that designed the new ///M5 don't think so.

I'll ask Steven again why he said skip that thermostat. I forgot why. I was gonna do the same, but didn't after he said not to. When he says do or don't do something, I listen, the why isn't as important.

The metal impeller pump is a good buy. BMW actually went back and forth with the plastic and metal impeller, the jury is still out. Both fail, but my money is on the metal impeller as well.
