boost break up problems

does anyone know where the knock sensor is located on the stock bp 05 motor with stock bp us harness

[Masterbanter]

There isnt a knock sensor on the BP just on the BPT.

so how do i bypass the knock sensor that the bp26 ecu needs 2 read from since the stock bp 05 engine doesnt come with that i think that that is the problem with my car bogging out and breaking up when i get 2 6psi

that isnt the problem. 90% of people use no knock sensor and have no problems. without it all the ECU does is retard your base timing by 1 degree.

sounds like you have a fuel delivery problem. what airmeter and injectors are you running? what throttle body/TPS?

+1.. i have a knock sensor and it dont make any diff between my before and after. its just a safety device. but im guessing you either running to rich or too lean.

iam using at the moment 460cc rx7 non turbo injectors and a stock bp vaf but i do have the stock 330cc bpt injectors that i could put in would that change things and going 2 a good o2 sensor

No knock sensor for me, works great.

What's your plug gap? On a stock coil you don't want more than about .027-.028.
