That's not a bad price. The ECU in the Z may be able to automatically compensate for changes in the air/fuel mix, I guess I would be more worried about not changing the intake. You're letting more air out of the engine with the exhaust, but you aren't letting any more in with the stock intake. I'm not concerned about gaining hp, but I wouldn't want to lose any. It does sound great though.

Yeah, I think you are right Fly. Of course, I will be doing intake, headers and HFC one of these days...well maybe... ;-)

Jon@Altered · 06-29-2009, 09:26 AM

Fly's correct to an extent; changing intake/exhaust components can cause the factory ECU's to make minor changes to it's Air/Fuel Maps, but not nearly enough to properly keep the car's Ignition, Timing and Fuel functions smooth and in balance. In some cases, the stock vehicle runs too lean/too rich throughout the RPM range. Keep in mind this happens when you do heavy modifications to the vehicles intake/exhaust components. When I say that, I mean changing the air intakes, headers, running test pipes, and full exhaust. Usually doing all of these bolt-ons can cause your car to experience some of the issues mentioned above.

However, if you just get an aftermarket exhaust for your Z, usually you'll be fine with just exhaust, or an intake kit. Anything in addition to these performance modifications and we recommend getting the car flashed. We're still working on a Reflash for the 370Z, and we'll keep you guys updated.

Hope this helps!

I'm curious, is there any kind of ECU piggyback system, like the Power Commander for bikes, that is made for cars?

For the 370Z(and all HR+ Generation Nissan sports cars), the "piggyback" ECU Control Units we've had the best experience with have been the HKS F-Con and Greddy E-Manage Ultimate. At the moment, there are no "plug and n play" Units that work for these cars either; the ECU systems have to be hard-wired in, in order to tune the car properly.
