You need to learn to read a dyno chart... The solid line is the power, dashed is the AFR which you see is in the low 11's.

Stock wiring has #10 going to injector 3&4, #20 goes to injector 1&2

I've actually never had a car dyno'd so you are correct i wouldn't know.


thanks for that conformation on those wires.

Check out my dyno chart above, the air fuel is pretty constant, no sudden drops etc.

Interesting that it still happens with turbo, I never knew that. IIRC, it's been found that the knock sensor is maxing out (like screaming into a microphone), so I wonder what is causing it? Too bad we don't have a brand new crate motor to see how it acts....

Might not be related, but I have heard stories of bad harmonics caused by the crank around that RPM on a few engines. Possibly it or some other rotating component is ever so slightly misbalanced from factory?

Well, pending the supply of the front bearings (I got the seals and rear bearings, they're easy to get), I'll be fully rebuilding my SC14 soon, so we can see what the dyno says after then. Will probably be the same, but it'll be interesting to see what happens with a fresh supercharger.

a mate of mine runs my old AE92 GZE ecu/whole setup on his NA bigport (going to turbo but hasn't yet) he has been running NA for a few yeard now.. and just left the knock sensor unplugged... it was on a bigport anyway we tapped a boss in the block around the same location to put the knock sensor on but it would run like shit with it connected..

so we just left it unplugged.. set base timing to a conservitave 12 deg BTDC.. he has been reliably circut racing it ever since..

also i never had an issue with my AE92 map GZE in my AE86... here is my dyno chart.. and a video.. definitly no power drop after 5500... why isnt it a universal problem? seems like it happens to most.. but not all GZE's..

if you are running the stock interwarmer i would suggest you don't even try running without a knock sensor..

and this is my bro in laws 86 that has been running the gze ecu/injectors/coilpacks etc etc for a few years with no problems without the knock sensor connected..

[mattysshop]

only real reason i suggest not running it is due to your running stock boost.. with no intention or raising it.. the GZE being quite tough... if you pull a tiny bit of base timing out of it, i can't see any real issue.. providing that you have sufficiant intercooling eg.. anything but the stock cooler..
