LED TVSV mod not working alkdfjaldfj, green red flash at boost. Options

[urbandork]

ok so after installing the LED knock light mod i have found that at any boost level my red and green led flicker on and off rather then just the green staying on. I assume this means i have knock in one cylinder and each time that cylinder fires my knock sensor picks it up and thus my green and red light blink on and off.

what could this be from? my oil does need to be changed. I guess i should look at the plugs right? compression test maybe????

i dont exactly know what i should start off with?

any advice?

i have a 255 wabrol pump, stock injectors and stock plugs and im running 91 octane.

please shed some light?

so i know its not knock now but something else. It seems to be wired correctly but still when im at boost the green led does not stay on. instead the red and green led flash.

and when my key is turned to acc. the green light is full brightness and the red is half.

for all you who have done the mod when the key is in the acc position what light is on?

i dont get why both are on the ecu and its tcp line must be crazy.


does it matter that i got my ground for the red led and power for the green led from the plug for the cig lighter????? perhaps maybe the current is to strong i dont knowalfhdlhfaldfhj

The red LED is dimmer because the VSV's coil is acting as a resitor.

The LED staying red when you disconnect the level sensor means that the VSV is staying closed which is absolutely correct.

The LEDs flashing back and forth can only mean that the 3rd gen ECU uses pulse width modulation (PWM) to control boost instead of a bleed type VSV like what the 2nd gen has. PWM is the same method used by fancy aftermarket EBCs.
