God is not interested in preventing or monitoring knock. You need to do that yourself at high boost so it wise to datalog when working the evo to get power, even better - SES light patch. I agree with you, 11.1 was probably rich enough by pulling power to safe levels

 

just went out and did 2 WOT runs in second, and its def the plugs breaking up. so new plugs tomorrow and i will see if that does the trick.

 

Knock sensor is looking out for all of us! And EBC's and ECU boost control for some of us

 

I am at 4600 ft in Oregon and its cold today but sunny....i drove my car for the first time in 3 weeks. The car is tuned at 24 psi. Will it be bad for the car if i set the same boost? It was tuned at sea level and brought up here. Only a summer car so i usually dont drive it too much. Dont boost too much either but today i had to for a tiny bit . Let me know.

 

ok, your car was tuned for 24psi. if your are still seeing 24psi at WOT at lower outside temps, then u are fine. if u see anything over 24psi, which is likely to happen, lower the boost until u see 24 psi again.

 

Ok.....thanks i will see what the car does at WOT. I can turn the boost down to 18 or so just to be safe. Thanks again.

 

there is no need to do that. if u are tuned for 24, then just adjust until u find 24.

 

If you were tuned for 24psi at sea level, you can bump it up to 26psi at 4600ft.

 

I know i dont have to go to 18 but just want to be extra safe....... Its like putting on a condom and pulling out before you blow your load. Extra safe .

I know i can bump it up to 26 or so but i dont want to go all out all the time and pump gas tune at 24 psi is good enough for me......its just a DD.

 

What i'm saying is if you want to still have 24 that you had at sea level, you need to see 26psi at your elevation.
Otherwise if you keep it at 24psi, it'll be more like 22psi at sea level..

 

yeah i know....thanks man. I usually turn up the boost to 25 or so in the summer time or if i want to race some one but for the DDing....i just keep it.

Thanks again for all you help guys. I love this community .

 

i was told by a good tuner that if i see more boost then usual in cold weather i dont have to turn the boost down couse an ecu wiil add more fuel and pull timing and my turbo spikes to 26psi in those conditions,just watch your knock sensor,if you see service engine flashing (if you have that option) go ease on a throttle

 

at WOT when your car is tuned, it will give the amount of fuel that is provided in the tune. so just upping the boost without more octane isnt a good idea.

unless i am wrong?

 

I don't even have a boost controller on my car right now but I'm hitting 20-22 psi with just TBE and then at about 5500 rpm the boost drops to about 8-12 psi and sometimes even 2psi. what is this and how do I fix it? My turbo still sounds like its spooling but I'm not going anywhere.

 

theres no wrong or right answer here, every tune and every car is different. simply if its cold weather, boost will increase. the safer/conservative your tune/car is at, the less chance a boost spike will cause issues. simple idea, yes?
