I like your attitude, Jeff! FreeEMS ALL THE THINGS! :-D

Wikipedia link for the engine: https://en.wikipedia.org/wiki/Nissan_HR_engine#HR16DE

DE means port injected, so running the engine is just a matter of understanding the VVT and whether it can be run without controlling it, or not, and what sort of decoder it'd need. The factory ECU might also control the CVT, or that could be separate with some sort of bus between them to assist in optimum ratio control/throttle input.

Is it DBW? That'd be useful! :-D I have one on my desk... ;-)

More pics of it, rear end view, higher res, etc. :-p

Fred.

DOH! I can't edit my own post anymore. :cry:

Not DBW. The service manual, strangely, is wide open on the internet in its original digital form and doesn't seem to be annoying Nissan at all. I'll start investigating the controller arrangement.

Port injected and not DBW, all you have to do is find out these things:

1) Crank/Cam signals, signal types, with precise angles, and pin out
2) CHT sensor curve details
3) IAT sensor type, and if good, curve details, if not good, how to easily rewire to a faster type
4) O2 type, location, wiring
5) External MAP? If so, wiring, and calibration data
6) Ground and power scheme so as to be able to connect things up correctly
7) Injector wiring scheme/pin out
8) Coil type, ignitor type, voltage requirements, pin outs, ignitor behaviour if not dumb, etc.

And probably other similar stuff, but you could get going with just 1,2,5,6,7,8 if you really wanted to. 3 can be configured to a fixed value 4 can be done by ear/feel/balls like #1 was. :-)

However I reckon you should focus on tuning the truck first, lol. Your sheer will power in ignoring the state of tune on that truck is impressive to say the least! :-D

Thanks for the useful info. Not in any hurry with this one nor have the money readily available to build a new ECU, just happy to have a placeholder until that day comes.

The bore and stroke are the same as my Miata 1.6 engine

Well, that ended rather quickly. One Versa Note off the list as a potential FreeEMS car thanks to massive road ice throughout town. Me and the oldest came out of the wreck fairly unscathed. Looks like the vehicle had the laugh (see the dash photo).

Glad you're okay! Funny, I was poking around at the front of one of these only a few hours ago - they're pretty softly built up front! Good for you, I guess.

And you no longer have to worry about the hail damage. Always look at the brighter side :-)

Do you not use studs or chains in these sorts of conditions? No way would I go out in such weather without them in any car, 4wd or not. Maybe they're illegal there? Not sure. Still, I'd probably risk the fine over the crash.

Thanks. I don't believe anyone anticipated the roads to be so bad and it came on sudden during work hours. A misting rain happened throughout the morning, so it appears to have frozen after abrupt snowfall. Haven't seen chains in town and you're likely right...that they don't want them on roads within city limits.
