According to my Electrical Engineering knowledges, the ecu now aday has the capability to programable and when you remove the power then it will restore the factory setting to start the car. That why everytime you upgrade something, you have to pull the fuse of ecu out to let it restore the factory setting and start sensing the air/fuel ratio to optimum the new upgrade. I do not we will ever mess them up. Of course those guy and those racing shop, they just want to make money continue for the rest of your car lifetime.

: Collective:

: I'm venting a bit here so bear with me.

: RDSport's UK Site has a PR for an E36/M3 Software Upgrades. You get Software on CD and Serial Cable (to go to a PC) so you can program your ECU yourself to tune it the way you want it to be tuned or to select various performance defaults.

: I called the LA branch of RDSport this AM. YES they have this software but NO they won't sell it to the consumer but will rather sell it as a service. And the fee will be about $400.

: Maybe I'm a little self-centered but wouldn't most people prefer to tune their cars they way they want to?

: Am I the only one who feels coerced by Dinan, Turner and now RD into buying an upgrade? And then as I upgrade components, returning to the vendor for updates?

: I can think of one vendor in the japanese import arena who sells programmable ECU's and the equipment who at least will sell the updates for a more down to earth $50. And you can even download these from his website.

: On this board, is there anyone aside from JimC who has programmed their own ECU?

: No disrespect to Jim or Dinan or anybody else, but for $400 I'd rather have a CD, cable and download the info to my car instead of disassembling, driving out to, or returning like a heroin junkie for updates.

: Flames anyone? Or rather, solutions?

: How about you guys who really race those M3's? Don't tell me one ECU flash will take care of all Road Course conditions....

: Sigh.
