Hi.

Some of you will know I got an Emanage fitted to my magna about a month ago. Now I have a query regarding removal of this unit from my car.

I was wondering if it is possible to simply unplug the wiring harness from the emanage unit itself without causing any problems. I understand that doing so (if it would work) will effectively return the car to its factory tune - which is essentially what I want to do as quickly as possible..... I'll worry about removing the wiring from the car at a later date.

Thanks.

why u removin it??? are u gonna sell it???

Not selling the Emanage.

You should be able to unplug it, if its been installed correctly.

I suppose there's not that much to loose....... if unplug and car runs like ****...... just plug it back in.......

that'd work right?

U selling car car?

As opposed to "your car"?

That's what I meant, Brain Fade :nuts:

Yep........ returning car to stock and off loading it.

Getting a manual? or just getting another brand of car?

All will be revealed eventually :D . Right now, I need to know how I can get back the factory tune - so that the car doesn't end up running to rich/lean when I remove all the mods.

Tried unplugging the emanage unit....... car wouldn't start. I presume by disconnecting it - I broke the ignition or injection (or both) circuit - and hence ECU wasn't able to send / receive the signals it needed to.

My next option is using the support tool to 'set everything to zero', hence returning to the factory tune. I don't yet own the support tool - and hence don't even know if this is possible, and if so how easy/hard it would be to do.

Any emanage users out there actually used the support tool??

Will it even cause any problems if I start pulling things like CAI, Fuel Press. Reg, Bigger Plennum off the car while it still has the emanage tune in it?? All my mods are essentially ones that you can do without having to install a piggyback - hence the factory ECU should be able to comphensate for them regardless. Am I right?

Honestly, take it to a mechanic or a tuning shop to get all that done. Save yourself the trouble of making things worse.

yeah if the installer didnt make a splitter cable and just hard wired it into the wiring then u will have to get him to unsolder and reverse it all

just a note for everyone thats going to install a greddy

i suggest using 2 x 20pin ATX computer power cables to make a splitter so you can just plug and play

Can you provide some detail on how one would do this??

Also - here's a hypothetical question: If I decided I wanted to transfer the emanage from my magna to another 3rd gen magna...... how difficult would it be to simply copy the wiring from the current car - into the other magna? If it were theoretically possible - I would most likey attempt it with guidence from someone with more experience than me at automotive electronics (mainly car audio).

All feedback appreciated - thanks.

Have you got wiring diagrams for the GReddy or can you tell me what wires it interacts with on the factory ECU.

Phil,

I don't have any wiring diagrams specific to the emanage unit (in english at any rate :confused: ). I have some wiring diagrams and pin-out diagrams for the factory ECU though (you probably already have access to these).

I was hoping if the current wiring setup in my car was scrutinized (ie: take photos, note which wires are joined to which etc) it would just be a matter of matching it in the second car.

Now that autobarn sell emanages on the east coast - I might be able to get access to some english documentation for them.

I have the supposrt tool software uploaded to my website. It's only 5mb. Pm me if you would like the address

can't see why you couldn't do a wire for wire swap between cars.
when removing it ya need to get to where it's spliced into the loom and rejoin any existing wires that may have been cut and connected soley to the GReddy.
I think you are already thinking along these lines anyway, but that's how I'd attack it. :cool:

Yeah that was pretty much the plan........ but it will probably be a while before I'm ready to tackle that job - and after taking my CAI and Fuel Pressure Regulator off yesterday the thing is using heaps of fuel......... so I better not leave it too long.

I've heard a rumour that ECU wiring differ between manual and auto magnas. If this is the case - is it possible that the two are so different that simply copying the wiring from an auto magna to a manual magna (same model) would become almost impossible?

Confirmed Auto is a 3 X 2 plug, four plugs in total, a Manuel is a 2 X 2 plug, four plugs in total and pins in different locations and colours.

Dave thanks for the quick reply....... unfortunately - worst news I've heard all day.

I'm no expert but looking at the Greddy wiring diagram, most connections are a "T" (spliced) and will not be affected by disconnecting the Greddy.
BUT, there are two signals which are intercepted and modified, and must be re-linked if the Greddy is removed. These are the signals from the airflow sensor (MAS), and the ignition signal to the distributer/ coil for timing. Naturaly the engine will not start or run without these signals being reconnected to the ECU.
From a Magna workshop manual, find the pinout numbers from the ECU for these two signals, and the wire colours and check whether these two wires have been modified.
Its difficult to give more info without actualy being there to look at it. Best of luck. I'm in the process of having a Greddy installed and tuned at the moment, with some other mods. Will be posting when all finished.
