4G swapping ECU's? What's possible?

Post by **vanzep** » Mon Apr 16, 2012 2:25 pm

cheers for the help guys..

ive unplugged the spoon vtec controller but engine management light still on and car not running well

ive also taken the ecu out but cant see any problem with the way the chip has been fitted - here are a few pics

Simple question first... Is it the right way around?

Yeah does the NS denote Near Side?

Also, there's quite a few scorch marks... They haven't broken any of the contacts have they?

i presumed NS stood for NucluezStyle

chip is lined up correct per instructions - we even marked the board on notch side with a red pen - you can see this in the photo.
i can see some of the scorch marks on the back of the pcb but only in the photos which are on super micro cant see it with the naked eye

I think the only thing we can do is try another ECU and have a poke about the chipped ECU to see if one of us can see if there is anything visually wrong

Yeah, definitely try a known working ECU first.

I'm here guys!

I can only be brief as I’ve been out of the office this morning and have to go into a meeting shortly.

Unfortunately I can’t see your pics in work, but you can email them to me: rob.wyatt@gleeds.co.uk

Mostly agree with Nathan so far, use Spoon JDM P13, UKDM no good & I can’t vouch for the P28 you have sorry.

The problem could be:

1) Bad soldering has broken contacts
2) Incorrect fitting (again can’t see pic and it’s not rocket science)
3) Could be a bad chip??? I’ve had two to date in the stacks I’ve sold now. I get batches of used blanked out chips from Hong Kong – I assume I’ve just had a couple of ‘bad eggs’. Not a big deal, probably about 1-2% of the ones I’ve burned and I’ve quickly replaced them for good ones and all sorted.

And yes NS = NucleuStylz.

Notch on ECU / Socket / Chip is very obvious and as you say it’s noted on the instructions quite clearly.

Right, try and email me some pics if you can, otherwise I can’t be much help till later.

I can stick another in the post tomorrow to try, to rule out a bad chip.

Cheers,

Rob

Ok, hope it's soon as my meeting is at 3:30!

Even with the pics it’s difficult to see damage sometimes. Can’t be worse than the ECU I had a TV repair guy do once. He broke VERY obviously 4 contact lines and tried to patch it up with wire. Safe to say, that one did not work and I had the exact same problems as you – this was my lude.

If you do spot an obvious break or bad bit of soldering, try and rectify it. While it was bodgy, a link wire might be the only option. (If this is what’s wrong???)

Think I’ll get a chip ready to go tonight no matter what.
