Which security torx to remove ECU shield?

[m1tch]

Hi all,

Just in the process of test fitting the Dastek Unichip for the initial 1/4 mile run - plan to do a few runs 100% stock then plug in the Unichip and do another few runs to see the difference.

I have noticed that I can get to the 2 top plugs (white and black) but I need access to the 2 black plugs, one of which I can see is behind a security shield with some security bolts - I am guessing these are T30 security torx bolts (with the pin in the centre)? Can someone confirm this as typically I think thats the only size I don't have after dropping it in the engine bay of my daily drive!

Need to know if its that size to order another to get the 2 bolts out to then get to the plug etc.

Thanks in advance!

They're 5-point security torx bolts. The key being 5. Try a 6 and you'll likely find yourself going at it with a drill or dremel

Awesome, thanks for the info, will check to see what sort my torx bits are, have seen you can put a small flat bladed screwdriver across 2 of the points and turn it - guessing they are standard thread rather than reverse?

Yes indeed. It depends on how tight the bolts are. Mine actually came out quite easily with a 6-point hahaa.
But someone else tried that approach on Stewart@Boro's car and we were left with rounded screws and no option but to drill and dremel.
So, for the sake of the effort of getting the right bit...

Yeah I put a screwdriver in there and thought...hmmm this might not end well lol I only have 6 point security torx so I have ordered a set of 5 points - will probably just replace with standard screws anyway or find an easier way to mount the ECU - the Dastek fitting instructions just show the connectors being unplugged with no mention of the security shield!

I could be wrong but I think I read that it's part of the reason why the mr2 is so hard to steal. The chances of a thief carrying around a spare ecu, with keys AND a 5-point security torx screwdriver is very slim.

At least its not a Toyota specific tool!

There are a couple of other bits that use the five point torx.  The idle air control valve is one.  A set of keys is not expensive, so worth having in you toolkit.

I figured that the set might come in handy for something else, always useful to have more tools.

Vw use 5 points on their mafs
