without ks!

[Godspeed]

can you run your car without a ks? i posted this in the 7mge section by accident so i am now posting it here sorry for reposting. when i started parting out my wifes car i found that the ks wire had been cut. but the car ran fine until it broke a rod. it had plenty of power.
so my ? is can you simply unhook the ks and drive it? i know its not the smartest thing to do but will it work?

 

[wingman]

if my understanding of them is correct, the car may throw a code but whether it does or not it won't detect the pinging of detonation and thus won't retard timing...making for a very sad motor.

no I have a back knock sensor and my car would not run it would try to crank but would cut off after the key was released

are you sure the ks cause your car not to run?

 

[Godspeed]

hahaha i get the joke thing lol but the car started knocking after i raced it one night and found that it was leaking oil.

having the KS(s) disconnected would have the exact same affect as if your wiring was toasted; both would cause a code 52, the timing would retard, and the fuel mixture would become more rich.

it's a common misunderstanding that the code 52 tells you that your engine is knocking. that is UNTRUE. the only thing the code 52 does is tell you that the ECU is not receiving an output from the knock sensor(s). if you have them removed, you'll have the exact same affect as if the wiring was cut, corroded, or shorting out.

if your car isn't starting, it has nothing to do with the knock sensor(s). you could pull them out, and cut the wires off, and the car should still start and run. (albeit, rich and timing retarded).

unfortunatly, the ECU will not show a CEL if you have knock.

ok thank you thats what i needed to know. my car starts and runs but has a code 52 and has no power. it also revs to 2k then cuts out and goes back to 1k then it will do it again.
also i tried adjusting the tps for the idle and i have it all the way to one side and it still idles at 12-1500 any ideas what this could be? or is it from the ks?

i never understood why when someone or something is telling you (in general) what the problem is, people still want to ask, well could it be something else? what is it really.

hey buddy, your car is lying to you, its just throwing the code 52 for fun.

the car is "cutting out" due to the code 52. your high idle i am not sure what the cause of that is, possibly due to your tinkering with other components.

you need to rewire your knock sensors.

further, you then need to READJUST your TPS the way the TSRM tells you to, then reset your timing.

 

[Godspeed]

well as far as the questioning other things. this is my first experience with the ks problem. i also appreciate the help guys and for the ones being sarcastic this is why people dont post up ?'s because some people act like the others here are fu@#$%# stupid when we dont all know the answers.
i thought that was what the forum was here for to find answers not smartasss remarks thx

well if you read my post including smartass remarks youll see a clear answer to your questions.

 

[boost fiend]

i run with the ks code. no problems. pulls like mad!

eh maybe you run with the code STORED, but not with the ecu actually lighting up the CEL while youre driving.

 

[theKnifeArtist]

so does the knock sensor ever have a big effect on performance? i've had the code for a while..i cleared it and got it again..and my car really doesnt seem to be running as hard as it should be? could it be the knock sensor? could it be the tps sensor too? cuz i don't think i adjusted that right. i have a 51 "tps idle switch contacts open" code..but i don't know what this means. i had the code before i ever touched the tps.

for the guy talking about the cut back from 2 grand back to under 1, did you take your tps sensor off and put it back on? because i put mine on the wrong way once(blades of tps and throttle not facing the right direction)..and i got that.
sorry if i may be jacking this thread

 

[Dirgle]

Yes, the KS has a big affect on performance. The ECU uses it to figure how much fuel and timing advance is safe. If it can't receive a signal from the KS, it will revert to default failsafe values, and you car will run like crap.

 

[Godspeed]

well anyway i appreciate the help from everyone even the ones with smartass comments. as far as removing the tps. no i haven't i just loosened it and moved it a little. today i removed the plug on the ks and it looks like it has been rewired before using some crappy wire and it had 2 places where it had be taped back together. so im guessing a simple re-wire will fix it i hope.

 

[lagged]

you need to readjust your TPS then if youve moved it. be aware that the KS wires are shielded. if you end up splicing the shielding with the signal wire youll have a short and still have the ks code.

 

[lagged]

oh and if i remember correctly, what youre looking at as someone elses shitty wiring job, its probably not. that tape is probably origional for the shielding i think. maybe im wrong. who knows.

Some people have grounded the KS wire to the firewall to disable it because it has the potential to take away power from a tuned 7M with the stock ECU.


I've read this somewhere before on these forums or SF regarding a high HP 7M.

 

[shaeff]

i'd rather have it as a fail safe. i don't exactly understand how grounding the wire to the firewall would work at all. the ECU needs voltage output from the KS to function properly. i'd think that if the wire was grounded, it would act as a short, and cause a code 52.

besides, in my opinion, a if a car is "highly tuned" then the KS shouldn't be picking up knock, and timing should stay as is, instead of being retarded.
