Good work

Odd they did that to the 03.

I have come across them on other cars, but not the S.

Did you butcher them?

04 on also has tamper proof ECU bolts

Yep, with a great big grinder . No choice it was near impossible to get em off, and a cover over the wires to stop you pulling the connectors out!!

All of my S2000s (99, 03, 07) have had the anti-tamper (round cornered triangle shape) bolts on the ECU. I thought all UK S2000s had them. There're easy to remove if you know how, no grinder required. You should have done a search on here, it's been covered quite a few times over the years.

Go on then tell me
IIRC my 99 was easy with molegrips but the later ones have protection all round them

RISLAR

Tell me also, my 99 had 10mm bolts!!

There's the uncouth way - 'gently' hammer on a socket. Otherwise you can get sockets with push in pins that can fit over any shape bolt - which is what I have. Or the easiest way of all is to borrow the proper tool, if you have a friendly dealer

My 01 certainly had them.

I just asked my dealer to remove them when the car was in for a service.

I tried the socket, was the first thing i tried to be honest, but no movement at all!! got them off in the end, just didnt expect it!!

My previous S, also a MY00, didn't have them.
