MFD setup and calibration info - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Hi all,

I know some have seen this before, but some have asked me recently for help setup up MFD II's after upgrades and this also applies to UK MFD's and other factory MFD's so I've updated the help file and thought I'd post it here for everyone so it's easy to look up.

I've been through the process as written here on my car with MFD II and it worked perfectly as described so should be the same for others.

Great post

Thanks Fraser

When I start my car in the morning, having not started it for more than 12 hours it sometimes shows the previous peaks on the MFD any ideas?

S2 GTR......... no idea on that one mate, never heard of the MFD remembering the peak values from a previous drive !!!

What section of the MFD is keeping the peak values ? The multi sensor display ?

Hope everyone finds all this info useful. Some of it is taken / updated from my experience, other stuff is from other people and I've just tried to put it all together in one place...........

Not too worried about it

All screens show the previous peak values?

Thanks anyway,

Dave

Sounds odd to me.........sounds like might be something wrong with your ignition that's leaving the MFD powered up............. only way it can possibly keep your previous values as the MFD has a volatile memory so no power supplied to it means it'll forget everything.......

Do you hear a loud click (assume from relay) about 1-2 seconds after you turn off your key ? Usually you hear that as all the electronics turns off.

Hi canman can you tell me what cable is best to use to extend the mfd loom as am doing the gtt mfd conversion just now. If have noticed i need to etxend the loom to reach the ecu and was wondering what cable to use if you could tell me? Also how do connect the mfd loom to the ecu cables etc do you cut the insulation back of the cables and fit bullet crimps on them and connect to mfd loom or is there a better way?

Cheers

Iain

Thanks for your your reply Fraser,

I do normally hear the relay click, it is only an intermittent issue-happens about twice a month? So it does not really worry me.

Your not alone Dave.

Mine does this aswell now and again.

Never really thought too much about it!

Hi Iain,

To be honest I'm not really best placed to advise you on how best to extend the loom as I don't work in the electronics trade, however if you already have the connector needed to hook into the back of the MFD then using normal cable found in any car accessory place will be fine and you're right you'll need to plumb into the existing wires unless you look at purchasing a short extension for the ECU end, I think HKS make them for their piggyback ECU's but you could purchase one and use it for your own purposes, but as long as you join to the existing wires in a sensible manner I don't see you having too many issues.

It might even be worth employing an auto sparky as it won't be a hard job for any of them to run a few wires and terminate them for you........ less risk hopefully........

Have a look here also if you're doing GTR to GTT conversion, Alex has done it successfully.

R33 GTR info......... if you fancy the task

Sorry, had to add this on the end as I can't edit my original post, maybe a mod might be kind enough to add this for me ?

canman · 4th April 2008, 03:07 AM

Sorry to all those who were put on the wrong track by my original post, I think I've updated these instructions so they're a bit clearer, and hopefully correct.

If there's anything which isn't correct, please let me know and I'll update my files.

I also have this in PDF if anyone wants it, just PM me.
