Does the post '03 car have a different ECU than the pre '03 model?
I ask as I bought a unichip from a fellow member from this site and when I met him he removed it from his car (to show it working) and showed me where it plugs in, but having just picked my older car up and having a look it looks to be different. If they are different will it still plug in and work as it should?
TIA

ECU Plugs are the same. There is an ECU revision but this wont effect you.
Did the Unichip harness also go with you purchase?
Yes, have the harness with it, just wanting to know I wouldn't fry any thing when I hook it up, Thanks for the info.

The difference you may have seen on the newer car, peppy, is the security plate that covers the ECU and partially covers the harness plugs. Older cars (and the MR-S) don't have this. So at least you won't have to worry about removing it s:wink: :wink: s:wink:
And yes, plug configurations and wiring are the same across the range for Unichip purposes.
to remove the security plate on a post facelift car you need a T27 security torx bit, pre facelift has a flat blade screwdriver bit
Thanks for the help folks, only done about 30-40 miles and the engine light is on, so it's going back to Mr T. So the Unichip fitting has been put on hold till it's sorted s:( :( s:(

I have a '00 X plate car and there is a black metal cover over the bottom half of the ECU, which is held on with some very odd looking screws, thought they were torx at first but on closer inpection found there something else, similar to torx but different enough for torx not to fit s:( :( s:(
They are the security ones like Stu said. Pre-facelift one had them as well.
Personally, I dremmled a slot in the screw head and took it off that way. I don't need no stinking metal plate! s:lol: :lol: s:lol:

I was getting Security Torx sets through my old mans garage. Unfortunately he has retired along with his Snap On supplier so I can no longer get them s:? :? s:? I have also left my plate off s:wink: :wink: s:wink:

They are securtity Torx bits i.e. Torx with a pin in the middle so the bits need a hole to match s:wink: :wink: s:wink:
Thanks to GSB for the link s:D :D s:D Unfortunately every time I have phoned to order some I get through to an answer machine s:? :? s:?

go to this link (http://www.facom.net/Frame.asp?langue=an&Cat=427) and type in EXR.127 into the search on the left, it'll give you a nice piccy of the screwdriver bit and shape, these BTW are orderable from Halfrauds
Stu, my local Halfrauds said they couldn't order it for me. (not sure if they meant can't be arsed s:wink: :wink: s:wink: )

sure my local one does Halfrauds, i'll add it to the list of things to check s:roll: :roll: s:roll:
For reference, and to ease confusion:
"Torx" screws have a 6 pointed star.
"Security Torx" have a 6 pointed star, with a pin in the middle that prevents use of a normal torx screw.
"Torx Plus" is a re-designed version of Torx, with only 5 points in the star, and the ability to handle greater torque. These are generally only sold to OEM's.
"Torx Plus Security" are 5 pointed stars with a centre pin. The tools and screws for these are ONLY sold to licenced OEM's, and are not supposed to be sold to the public. These are the screws fitted to the ECU covers on ALL UK sourced MR2's, pre & post facelift. This is the additional mod that Toyota GB carry out to the cars at port to gain Thatcham 1 certification. Euro imports, and grey imports from Japan and other territories, do not have this cover fitted.

Sorry Grant but thats wrong, Liz's 2 for instance had a flat blade screwdriver bit on it and mine has a 6 pointed security Torx screw
I was under the impression that 6 pointed screw without the pin was just a star drive, and a torx had the pin, but the screws on the car are 5 point stars with pins.... which will be getting cut off at the weekend..
Why do we need so many different types of screw? If toyota use them to stop the likes of us removing them there wasting there money, and wasting our time and money! The only people with any gain is the folks that make the tools as we all need 10 different screw drivers where one should be enough!

I removed the torx "gamebits" from my gamecube without the special screw driver. This is how....
I heated the end of a biro until it melted then pushed it onto the screw and let it cool there.
It dries into a perfect match then you can twist away. Might be worth a try before cutting anything.

Ps heres some picks if it helps...

No its not... Trust me... Liz's car had flat headed screws in there, because I put them there. She' didn't have the correct tools for removing the cover again, so I replaced them with something a litle easier when I installed her Unichip. Your car is another story, It may be that for some reason your ECU has been out in the past, and the Dealer responsible didn't have the correct screws to put back in once he's lunched the original ones (not an uncommon occurance, according to the Toyota Tech I spoke to), so you have the ordinary 6 point security torx. But of the other 20+ Unichips I sorted in the Group Buy, none had 6 pointed bolts. That would have been far to simple...

Can confirm that mine were Torx Plus security ones along with about a dozen others that I sourced a set of bits for s:wink: :wink: s:wink:
