Guys, people do a lot of engine tuning on cars like WRX's because they're TURBOCHARGED. You get a TON of power from relatively small tweaks. Doing the same for a NA engine like those in our BMW's gives you comparatively little power. I know Vic Sias got about 30hp from an S50 motor by going to Tec3 and that replaces the entire DME instead of just diddling the fuel maps and timing. You can get that out of a turbo motor just by looking cross-eyed at it. - Mark ------------------------------ Date: Thu, 18 Mar 2004 14:39:25 -0800 (PST) From: Brian Daley <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: Paucity of BMW computer tuning Message-ID: <[EMAIL PROTECTED]> You've kind of proved his point: Motec M600 ~$3400+ Electromotive Tec-3 ~$2500+ The WRX tuner is ~$550. Granted the WRX tuner's capabilities are relatively limited, but most people don't need a full-blown standalone engine management system. For BMWs there's pretty much nothing available between the standalones and a Shark injector either price or capability-wise. Kind of surprising as Bosch ECUs are used in a number of other marques besides BMW. A DIY tuning product for Bosch ECUs could cover a wide range of vehicles.

There is not much performance to be gained with a different exhaust system. Saving money is always good. I've gone with the least expensive option more than once. I vote for the M3 exhaust.

Geez, I would have thought you would have chopped off the roof, dropped the car to the ground, installed some dubs you got as "freebies", converted it into some other contraption and then finish it all off with some type of crazy paint job. Strange, I thought Jesse did everything like he does on Monster Garage. Anyway, welcome to the group. UUC makes some good stuff but I have no first hand knowledge of the TSE-2. I think your best bet is finding someone in your area in order to take a first hand look and listen to it since sound is one of the more important features of aftermarket units.

Message-ID: <[EMAIL PROTECTED]> Positive camber needs more toe in as the tires tend to roll in a cone and toe out. This is usually good for tracking, some positive camber and plenty of toe in. Maybe the inflation is low.

Message-ID: <[EMAIL PROTECTED]> sooo...can we derive from this that extra negative camber tends to inhibit good tracking? Can you compensate via a toe adjustment? If you add a one to two degrees of neg camber to a street setup, what (if any) would the compensating toe typically be? cheers!
