Hi, both my mr2's at toyota dealer today to swap exhaust, manifold, and unichip. They've just rang to say when the plugged in the unichip onto my new car it wouldn't start, when they took it off again it wouldn't start either. They say the ecu is frozen and don't know how to get it going. want to chrge me £550 for a new one. Anyone know anything, or is d'ck off suspension yet and i could ask him if i can get an ecu from his breakers? Whether its the dealers fault at the moment is irrevelant i just need to get it going again.
Many thanks,
Dave

Never heard of this happening before, disconnect the battery and leave it 15 mins, connect it all back up and try again.
If it really is totally fubar then I have a spare ECU, keys etc
Uk, thats great. am off to the dealership now to speak to them, will be back online in about an hour. let me know how much you want for it. its a manual no aircon i've got 03 reg.

Extremely rare for an ECU to blow, or "Freeze".
Unichips have been known to pop their clogs, have they completely removed the plug & play part?
They have checked all fuses I takes it (IGN2 is a favourite in these situations).
You would do best to get hold of an MR-S ECU to avoid the immobiliser situation (keys not coded to it).
Or an Apexi PFC would likely cost the same as MR T are quoting for the standard ECU.
What a pain!
Dealer broke it?
Dealer provides courtesy car?
Or dealer broke it, dealer fix it!
Okay my moneys on they have the ecu memory switch off (US chip?) so it wont start then they botched the uninstall and it still wont start.
uk, am online at the dealerships. pm me with a price for your spare ecu and keys, will have to go down that route. need the car back. Ta

They've checked all the fuses.
They've removed they harness, plugged in their readers and there is no connection to the ecu. Whatever has happened it doesn't work. So am hoping Russ can help me out with his spare.
At least I've got the new sable back (they swapped the working ecu from the blue into it) and reprogrammed my keys.
And I have a unichip + harness sat in a box, but daren't risk plugging it back in again s:( :( s:(
Thanks chaps for all your ideas.
Dave.
Will be posted ASAP!! s:) :) s:)

Or at least make a contribution or heavily discount your bill and make sure they don`t charge for fitting the ECU.

Any update on this?

...or, Dealer will blame Unichip. Surprised they would even touch the Unichip actually, my old dealer used to refer to my H&S exhaust as 'Non-Genuine' on all paperwork when servicing, MOT etc. and made no comment on the state of it during inspections where they were checking everything else.
Dealer agreed to do all the work, the mechanic used to own mr2's and new what the unichip was and also about the precats.
Just waiting for a reply from Russ.
Unfortunately, i need to go to work now.
The dealership have the ECU I bought of Russ,put it in the car and they have tested it with their readers and it is communicating so it works. However they need the key that goes with that ecu (or the innards from that key to swap into mine) to get the car to start.
Hopefully Russ has the key or I'm back to having a dead car s:( :( s:(
Dave
cant they use one of there computers to program the key. i mean otherwise how do they do it at the factory when the put a new ecu in.
I still dont beleive they need the keys, can anyone confirm?
If they need the keys surely they will need
Body ECU
Keys
Door locks
Ignition barrell
Glove box?
Cant they just reprogramme the keys in the same way they did on Monday?

I believe you need at least one
master key (actually just the immobiliser chip) paired to the ECU in order to pair a new key.. I stand to be corrected, though. (They wouldn't need all the other stuff you listed, just the key or if not the key, it's immobiliser transponder chip)
When I had my 2zz + ECU fitted to my car by Rogue they said I needed to have the ECU which is paired to the coil around the ignition barrel and the the key which is paired to the coil. Don't know if this is correct though.
EDIT: After the conversion was done, they reprogrammed all my current keys to the new setup.
I think they need one of the keys so they can add the new ones to the ECU immobiliser.
They can then send the key back once it's done ... it doesn't even need to fit the lock, they just need the transponder to pair with the ECU.
Cheers guys, transponder going out in the post.
Dave, apologies for the mix up
Thanks for everyones help so far...fingers crossed for the weekend

Sent it first class on Friday, we guessed there would be nobody there to receive it on Saturday so should have arrived today s:shock: :shock: s:shock:
Having done this on the past swapping the transponder is All you need to do, to make the new ecu work
Cheers Mark, we guessed that was the case but he wanted the whole key so sent out the whole key on a return basis, just gutted it didnt turn up today
s:bounce: :bounce: s:bounce: Garage have rang to say she's fixed and I can pick her up tomorrow! Thank you so much everyone that has helped... Russ please pm me with an address to send the key back to!
Does seam a bit heartless now after all this I will be putting her up for sale s:( :( s:(
I just hope Mel has a happy ending to her problems too... s:shock: :shock: s:shock:
Dave.

Great news!

She's back on the drive! Am posting your key off now Russ - thanks again s:D :D s:D

Just bumping this old thread back up, as my daughter has found my unichip in the loft, and is thinking of putting it into her mr-s. I don't know if it works,or if an mr-s ecu is even the same as it doesn't have immobiliser or post cat sensors, are the connectors even the same in an mr-s. But it will be something we'll have a look at, even if i need to get a spare ecu with a key from a friendly breaker. Keep the old tech going!
Can't imagine it won't work.
All it connects to are maf,TPS, rpm,injectors and ignition.
Unless the unichip is much more involved
