Need someone to do me a favor

Ok important question if you disconnect your ecu what still works. Looking to find out if windows, locks, blower/vent controls, stuff like that still works if someone can pull the connector off their ecu and try some of that stuff out that would be great, my car currently doesnt have a harness in it so im kinda outta luck testing it myself.

If I had to guess most of this stuff will not work however dont quote me on this.. May I ask why it matters?

Ecu delete, and yeah I know some or most of it wont but I'm looking more of an actually tested answer. I figure its not terribly hard pull 6 screws drop the glovebox and disconnet ecu connector

edit oh and the lights need to know if those will work

if nobody ever gives a true answer. I will do it tomorrow after work.
it wont be a hard job since I removed the glove box a while ago

I really don't remember what worked or not when I did the wiring setup last winter.

Only if there's a separate body control ECU, which I believe there is...

However, whether or not it works without the EFI ECU is anyone's guess.

Check the shop manual?

Already did no mention of what will or wont work. If fan speed and vent controls, lights, doors and trunk, wipers, radio, steering lock, all work then hooray i dont need to replace them. Each one of those is a significant problem to replace, doable but im trying to keep the cost down.

Oh and there is a bcm, ipdm, security module, junction box, and a couple other non ecu boxes that handle a lot of these functions but i dont know how reliant they are on can data, the vss is actually routed through the bcm so abs should still work though i doubt it will.

Eventually i plan to rewire the entire car to shed a 100lbs of wiring

Damn, I can't believe there is that much weight in wiring.

This is exactly what I wanna do. I'll be looking out for your thread!

steves · 11-26-2013, 01:24 AM

yer, these car have all sorts of modules. A bit of a over kill for a NA sports car which needs to be light. The AUS version even has pop up hood system which adds another 2kg up front.

Remember to recycle the copper.

Copper is heavy and when the car came out nissan had a blurb that advertised that they went from 5 miles of it down to 3 or something along those lines.

It might be easy to test without any wiring changes -- aren't there a couple of dedicated EFI ECU fuses?

If so, you should be able to yank those and operate everything else (other than starting the car, that is). Should even have lights, etc.

1slow370 · 11-26-2013, 12:35 PM

yeah i just don't know if the ecu fuses feed any of the other modules further down the wire. I don't even have a harness or motor in the car so I couldn't even try that.

I shall take you up on that, You would probably need to disconnect both your ecus, and if you could just make a little list of what does or doesn't work that would be great.
