Just about ready to fit the MegaSquirt. Taking my time as I want a nice
neat reliable installation. Made up a complete new wiring loom for the SD1
injection - in all the right colours.

But decided a wideband O2 sensor was the way forward - allows the MS to
stay closed loop over a far wider rev range and load. So had to get a Tech
Edge unit as the MS doesn't support one directly.

The sensor has to be fitted much further back than a normal one - about 1
metre from the nearest exhaust valve. So underneath the car. Found
somewhere with plenty space just behind the gearbox and marked the pipe.
Then removed it - which meant virtually taking off the entire system.
Still, it needed some work at the joints, and a heatshield re-welding so
no bad thing.

Cut the hole and got the boss TIG welded into the SS pipe. My shoulder is
playing up so didn't get round to reassembling until this weekend. Had to
get help to tighten the furthest nuts. Car up on axle stands in the road.
Cut the hole in the transmission tunnel for the cable and go to fit the
sensor. To find the one bolt into a captive sticking through the tunnel
for miles fouls the cable. Half an inch in any direction would have been
fine.

I've ordered up another boss and a blanking plug and I'm going to get the
firm who did the welding to do it all. ;-) The guy guessed 50 quid should
cover it. So much easier with a ramp.

Next problem is where to fit the knock sensor...

On the later 4.0 and 3.9 engines, they are fitted with a through bolt to the
block, one on each side.

Depends on what type of fitting yours have as to where it could go.

Where on the block? I was looking for a suitable flat part to give a good
acoustic contact. I'm happy enough to drill into the water jacket and fit
a stud. But obviously would prefer to know where the wall is thick enough
to allow a decent length thread. I did wonder if the engine mounting would
be a good place or too far away? IIRC, the best place is well away from
any mechanical noise but close to a cylinder. I've seem them mounted on a
bracket fixed to the cylinder head - but not sure how effective that would
be.

Single hole fixing - so a stud and nut would be ideal. A stud rather than
bolt if going into the water jacket so it can be sealed.

Dave, just above and to the rear (3/4") from the centre core plug, either
side of the block, is where landrover fitted theirs, so location-wise for a
signal that'd be about right. As for block wall thickness on an early block,
I'm afraid that'll be a case of try it and see, but a stud is definitely the
way to go, landy version is an M8 thread. You might have to get the block
tig welded up to provide sufficient metal for screwing into, or maybe a
product such as JB Weld would do the trick?
