Im working on my 92 B4C. Both of my block drains on my 412 are stripped. Even the snap on easy outs wouldnt budge them. Now that the motor is in and they are so inaccessable to torching or tools. Where else could a person put the ESC sensor? Somewhere less sensative but still functional would be helpful. If I just leave the wire dangling the thing throws a code 43 at startup, and that makes it run like hell of course. I used to do this all the time on my 85 TPI but this 92 won't do it. Am I going to have to burn a chip and delete code 43? Im thinking of checking out the clearance to put it in the block oil pressure hole under the distributor. I'm worried that the it might be too noisy in some of these places.

 

Do a search for "knock sensor bypass"...IIRC there's three different resistor values, one specific for your ECM.

Wire the resistor to the KS line, to ground.

You'll never detect any knock, but you'll never throw a code either.

 

hmm that sucks... i dont suppose it has to be near the cylinders to work? maybe a coolant output somwhere else would work?

I would think somwhere in the intake manifold may work... its right above the cylinders and frequencies travel really well through water, so the sensor should work right? maybe a bit less sensitive...

or maybe you could drill a new hole? or maybe in the head coolant passages? or if it doesnt have to be in coolant to work maybe in the fuel pump block off plate? thats sort of close.

I dunno just throwing ideas..

 

could you drill them out?

 

there is no access to drill

but king talon I like your FP block off plate idea, I will drill and tap it tomorrow.

 

I just hope it doesnt have to be inside the coolant to pick up the frequencies. do you have an engine managment software with sensitivity control? you could set it really sensitive and see if it picks up knock.

 

Just an idea, but they make special drills just for something with limited space. Maybe you could rent one to get it out.
