chip vs. ecu flash

[19ESZ398]

My friend just got a 98 m3 its in perfect condition with active autowerks exhuast, dinan intake, flashed ecu, ssr competition rims, and coilovers and adjustable dampers. I envy him, but anyways i was wondering if it would be better to get a dinan chip (im guessing it not as easy as plugging the chip in) or send my ecu off to have the ecu flashed for my 98 2.8 z3. Also wondering if there were any cheap springs for my car, all i want is a 1.5 to 2 inch drop cause im up as high as my friends dads 740li.

dont chip it

you cant chip any car >96. They are OBDII and need flashed.

What you want is the Conforti Shark Injector, that device lets you swap between the stock program or the Shark program as you wish. Don't expect any big improvements with it, but it does give you a couple hundred rpms more before you hit the rev limiter, & it removes top speed limiter(how often will that be used?).

Most springs are not expensive, but why bother with just springs , go ahead & get some good shocks at the same time.

You can chip a 1996 or greater ECu, it just needs to have a socket soldered into it, or the chip hard soldered to the ECU. I like this route because when I make changes to my set up my tuner just sends me a new chip, no down time. If you want to revert to stock, this is not for you.
