I have a GT 2 months now. Barackpore dealer out from Tokyo.
Its a Nov 2k5. GT with Safari lights IMPUL Hi power Control ECU and IMPUL coilovers on 18 Inch rims 50 series Toyo rubber. Even got a full 18" spare. 2.5" S/S catback system, 3.5" Chrome tip.
Standard tranny.....no 2WD option. Auto and 4WD lock.
OK....the good the bad the ugly and the makeover.
Good:
Pretty, fast, Nissan. Turbo lag is non existent, well nearly.
Bad:
Got a major fuel appetite ....16L per 100K or 15mpg...easy drivin.
Intercooler heatsoaks in traffic, or any time u slow down. Its 1.5" over the head. Gonna fix that soon.
A/C kinda struggles a bit....but thats a general Exy issue.
Ugly....
Ain't nuthin ugly, unless u think chrome bullbars with gold rims is ugly.
Makeover:
Ok boyz n girls...this can get heavy...so suck it in!
First there's the carputer.....I built and installed an Intel ATOM 1.5Ghz, 2GB RAM, 120 GB HDD, 8" 4:3 aspect ratio, 1024 by 768 Touchscreen with Centrafuse Automotive software along with regular Windows 7 goodies overlayed on a Win XP sp3 OS. This runs a Zoom swivel Camera for rear view, along with Vehicle Diagnostics, Music videos, NAV capable, Audio interface, radio interface etc. etc.
Here's a piclink of the desktop in the dash.

The Nissan Consult II diagnostics(...I am soon to be a distributor. for the Caribbean) allowed me to analyse the vehicle sensor logs....and it turns out that the IMPUL HI POWER ECU is a chipped stock ECU which goes WOT open loop as soon it can at 1700 RPM or so. I guess they think that is a good thing.....along with No fuel/rpm cut and mebbe variable VVL setpoints.
Well...unless u drive offpeak at hi speeds 1700 RPM WOT open LOOP means excessive fuel burnt as a daily driver.
So what to do? New ECU?
Heck no......ah be trini. Here's what I did....
I built an ECU interceptor ...yes I did..took 1 week afterwork to design and build using 6 opamps. And she works great.
I now have closed loop control at RPM's I want and I can govern the fuel use based on reconditioning the MAF voltage on the fly via a dashboard control. Naturally the interceptor is smart...it won't allow lean boost... just lean cruise up to my set point of 3700 RPM. At over 3700 the ECU can do its thing cuz we be launchin'.
I am presently working on a smart digital boost/O2 gauge. This Autometer lookalike will not only read boost and O2 rich/lean it will alarm in Lean boost and it will give a 12V trigger to trip a relay upon a lean/boost condition for those who need to trigger an additional injector or a fuel cut or a remap of the MAF or MAP voltage to compensate rich.
If you folks like the concept I should be able to deliver this dashboard device at around 500 to 600 TTD. If u saw the pic of my touchscreen install.....you realise that I make stuff that works and looks good. That dash was cut open and retouched to accommodate the 4:3 aspect large screen. The screen was separated from its housing and mounted to fit flush like a stock dash add in. A lot of hot knife and dremel work.
After this smartboost gauge and intercooler mod....I am lookin' at an in car refrigerator, hopefully by December that should be in place.
Just fyi... I am a controls/design/manufacturing engineer with mechatronics experience.
