kr and pinging
I have a 93 ssei with 2.2 pulley gutted air box, colder plugs, flowmaster exhaust,180 stat, boost mod, tps mod, high speed fan switch. The car usually runs around 170 -180 degrees. I get massive amouts of kr to the point that the car actually pings. upwards of 20 degrees. I have changed the knock sensor and the computer with no difference. The car is giving no codes. Any ideas????
What is the average amount of spark advance that a car should have at wot? I have seen numbers as high as 50 degrees but not necessarily at wot I have about 24 degrees at idle, is that correct? The other thing is that when the car is pinging the scan tool shows no kr. When i let off the throttle the pinging goes away and then the scan tool shows kr. My next idea is that the chip is screwed, reading on alldata the chip plays a major role in the control of kr, is this true? Any advice would be appreciated !!!! |
i think that 2.2 is causing maybe alittle too much boost
|
It might be causing some but most guys that are out there are running 2.2 with no trouble
|
Do you have an aftermarket chip? If so trying replaceing with your stock one. Also if possible try a larger pulley. Pull your plugs, tell us how they look. Also scan your L-Trims.
|
Still running the stock chip. I will try putting the stock pulley back on.
|
you run 91+ octane?
|
92 is the highest available here and that is what I run
|
What do you have for plugs? Tell me it's not Bosch. I suggest NGK TR55 gapped at .050 or .055". I used to have a similar problem, though I never had a scantool on it, so I can't attest to that part. But the 1 range colder plugs certainly helped out.
|
plugs are exactly what you said, but gapped at 60
|
Pull the plugs....check them out....and regapp at .55" as suggested above.
