Topless in Temecula

Today's victory goes to the bolt. After using a brand new allen wrench - 6mm - and penatrating oil; after trying to cut a screwdriver slot in the bolt head (we did) - more penatrating oil - THE BOLT WILL NOT BREAK LOOSE So I have resigned until tomorrow when we'll try an "easy out" to see if we can get the bolt out. If not - off with the head and then the "easy out" - new bolt in either case. The good news is I was able to disconnect motronics from cable after removing the bolts holding it in place, did open the box and swap the chip. Can't get cable back connected dispite two cuts and over an hour of trying. So far this easy DIY has taken 5 hours and we aren't done yet. So much for the easy DIY (it would be if the saet bolts came out or Porsche used a bolt made with something otherthan cheese). Thanks for earlier suggestions. I surrender

I went through the same exercise this week. One bolt did not move. I grinded the head down with a Dremel and used 2 cutoff wheels. It took me 20 minutes because access was still limited. If you do not have a Dremel, this is the time to buy ...

P.S. Replace all screws. I got them at Home Depot for about 50 ct each.

Hi Peter,

Sometimes just a few taps with a hammer and chisel in a CCW direction will get the bolt loose, quicker than an easy-out.

i too did my install this weekend. had the same hassle with the security bolts. ended up just drilling them with a standard drill bit. 3 came out by driving a flat tip screw driver into the hole I drilled and backing the whole bolt out. the one that wouldn't budge I drilled the bolt head off and the remaining thread just spun out of the hole with the drill bit. a pain but not too tough.

I'm having other issues - after idling for a minute with the new chip in it the motor quit. won't restart. Steve was very responsive via email and we are diagnosing it. I will put the stock chip back in and I'm also wondering if the DME relay failed. hopefully I'll get to run the new chip soon!!!

Well
I consider myself lucky. A few weeks ago, I swapped both seats for the same kind, just newer, and my bolts were no issues. So when it came time to swap the chip, it was done in no time!
Hang in there, it was worth the wait for me.

What size are the bolts? I will get some machine grade bolts from work. I fought with this in my old car when I changed the seats. I am going to take these soft bolts out of my new car and replace them with hardened steel or stainless bolts when I swap seats this time.

I confused. Do you guys have ABD with the extra box or ???

I was able to move the seat back, unbolt the motronic box with a 1/4" drive ratchet and swap everything out in about 10 minutes. But, I don't have anything under the seat except the motronic box.

BTW, did some testing yesterday. New post to follow.

Someone has been in your box. Hex bolts were NOT factory.

HEAT!!!!!!!!!!!!!!!!

Did you try heat????????

VNTGSPD

I don't think so. The box and tabs were pristine with no marks whatsoever. The plug also looked like it had never been undone, but who knows?

My motronic box is held in with two hex bolts toward the rear and two studs with hex nuts toward the front. All is accessible without removing the seat. But, I do not have LSD/ABD or anything like that.

According to most, ALL 993's left the factory with security bolts NOT hex bolts.

But I do not know that first hand-just information from Steve Weiner at Rennsports and my tech here in KY.

similar to others, I too didn't have the security bolts and the ECU was unmolested (unless the whole dang thing was replaced at some point in the past). The box was just secured to the frame by four 10mm nuts. chip came out, chip went in, did the whole start procedure and off I went...no issues.

My highly technical A/B comparison was my 12 year old daughter who likes to ride with me. In her final analysis, she concluded the car goes faster. Good enough for me....

PAG didn't start using the shear bolts until they started shipping cars out with driveblock so chances are that early model examples (and then some) won't have them?
