Well, its been a little while and I haven't updated this, and a couple of things have happened!
My nice HKS winged sump turned into a big paperweight! POS didn't fit. Turns out I have the same sump as you VQ25 bunch. So I sold it off to a 350z bloke, who has s/c'd his Z. Got moneies back, plus a bit extra, so happy there. Have now modified a stock VQ25 oil pan to suit with an oil return.
I ordered and received some spark plugs from Concept Z, one step colder than stock - so much cheaper than getting them in Aust.
And the big thing, is that I have been talking to Mark from Abbey Motorsport in the UK. They are the UK salespeople for the UPREV Orisis tuning system. We have decided to give it a shot getting UPREV to tune my car. Pinout on the ECU is the same as a 350z, and the Part # for my ecu is 23710-7W065. They have 23710-7W060 on file to work, so I am hopeful that mine won't be a problem. The software I have downloaded already, looks easy, and provides all the parameters of the stock ecu, including diagnostics, speed limiter, rev limiter, idle RPM, cam timing etc etc. What I have to do is dump my ECU program and send to them to confirm, and so they can keep a copy on file for return to stock. My cable is in the mail, so I'm eagerly awaiting that! Once confirmed as working, then I'll find a tuner willing to work with the UPREV.
Plan is to start the work on the first weekend of the new year. Meanwhile a Sydney 350z just completed tuning at a HKS workshop- 244rwkw on 5.6psi Thats with no cam control, cause the VPro can't do it.
Merry Christmas to you all, stay safe, and Stagea ON!
