Ok so heres the deal i know i need a knock sensor for this car its a 96 integra with an ITR ecu the swap is an LSVTEC but the knock sensor isnt hooked up yet. Now what will it cause will it make it bog out sense it thinks it has a misfire in cylinder 1? The reason i ask is because i cant get the car to run right i have a feeling its a timing issue i checked it i know it has to be + or - 16 right?

 

Well if it is infact your knock sensor, you can bring your ecu somewhere to be programmed not to look for a knock sensor.

 

I know i can do that but i want the knock sensor for now im just trying to figure out why my motor is bogging out so hard when there is a load on it

Not with OBDII ECUs, which all ITRs were.

OP, if the ECU senses no knock sensor, it is going to retard the ignition timing and you will have no low RPM power.

 

Ok now thats what im thinking but how does it retard the timing? its a distributor so how is it going to retard the timing? i know if it was coil on plug or something it will retard it enough. Ok now just to make sure when checking for timing off what line do you go off of on the crank?

 

anyone??

The ECU reads the CKP signal from the distributor to determine when to fir the fuel injectors and ignition. If the ECU is not receiving the knock sensor input, it retards the ignition timing to protect the engine from detonation. Adjusting the ignition timing to compensate for the ECU retardation is going to yield advanced timing at high RPM. Get your knock sensor installed.

 

ok so pretty much its bogging out because of the knocksensor

 

Now im trying to figure out if the knock sensor is my only problem. The Dizzy is advanced all the way and the red mark is at 0deg wich would indicate that its 16 deg retarded now is the knock sensor cabable of retarding that much?

 

?bump?

 

anyone?

 

Check the timing belt installation. Cylinder 1 at TDC (white mark on crank pully) and pull the valve cover to inspect the cam gears. ARe there any CELs?

 

Yeah ive done all that the engine is dead on , i had a knock sensor code and now i wired a Range Rover knock sensor and the code is gone but now i have a p108 map sensor high circuit. with a scan tool live parametes it reads at idle 52 for the map and thats what it reads with it disconnected i've been trying to get a good diagram for pinouts for a type r and a regular ls because i know it has to be a wiring issue im using the stock ls harness with a itr ecu.

 

bump??
