Any tips for the dyno?
I'm going to dyno the beast this Friday in preparation for a TS reflash soon after. I really want to get the a/f evened out and the vtc/ignition timing changes, the other stuff is cool but really just icing. The facility uses a Dynojet 248E chassis dyno and a wideband O2 sensor.
Besides noting the offset in measurement between tailpipe and the O2 bung readings, what other things should I look for/be aware of at the dyno on Friday?
I will remember to turn off the a/c
When I get the reflash and the last dyno, I'll post up the results.

There are several comments in Chebosto's thread on the '04 ECU that state that anything built 10/03 or later can't be reflashed:

I thought I remembered seeing a thread a couple days ago that they had finally broken the code for the '04. dont know if they are reflashing yet but they made big progress with it

Ares: Nice tip. This is why I like this forum. BTW, the blinker and driving light LED bulbs are great
DavesZ#3: When I talked with TS they assured me that 10/03 z's were reflashable. They've even had success reflashing z ECUs as far as out as 12/03.
Hugo: Good one. Already checked, 35 psi all around.
I don't except any problems (fingers crossed).
