How to Remove Tamper Proof ECU Bolts
There are (4) hardened tamper proof bolts that secure the cover over the 993 ECU under the drivers seat. I've done a search but cannot find any discussion of the easiest way to remove these bolts in preparation for removing the ECU. Will someone share how to remove those bolts easily?

Hi Ernie,
I removed mine a few weeks ago, using a sharp chisel and a hammer. You need to hit them from the side, at a sharp angle, in order to push them free. Then simply unwind using your fingers.
I hope this description makes sense to you. Unfortunately, I don't have any photos.
Try to do a search on Steve Wong tuning chips. I got the instructions from a thread about installing chips.
Good luck!

RyanPrisco is the same spammer who used the name "ClaraJohnson" on the 993 board a few days ago. https://rennlist.com/forums/993-foru...ml#post9739221
A quick check of his posts shows that he answers with near monosyllabic words such as "bump", "agree", "thumbsup", "support", etc., just like Clara did. A latent hyperlink (I will not post it here and have deleted it in the quoted text) is embedded in the responses if you do a search on his posts, but the links are not visible or active when you look at the actual posts in a thread. (If you quote his post, the link will appear in the quoted text.)
Mods, please remove this post? Also, can you block the IP address to try to get rid of this lowlife? Thank you.

my update on removing the security bolts...dremeled a groove in the heads, used a chisel to loosen (striking lefty-loosey) then used a screw driver to remove them. Wasn't really too comfortable with using forceful chiseling around the electronics (which I assume are somewhat sensitive to vibration). Worked like a charm. Will replace with proper bolts.

I just did this a month or so back and tried all the various methods listed here. The easiest, IMHO, was to use a rotary dremel tool with round blade (?) to cut a notch in the center and unscrew it with a screw driver. I was able to unscrew without needing force -- chisel or otherwise, just unscrew it. See the pic below for the right blade....
