This might sound stupid but what is detonation? I;m putting a ztube, Jwt pop charger in my car this week. Is three something i should know?

**thatguy** · 04-13-2009, 02:44 PM

engine detonation

ok i read up on it, but with the pop charger and z-tube, what are the chances that would happen, a million ppl have this mod, what are the chances?

You only have to be concerned if you have the cobb accessport as well.

**thatguy** · 04-13-2009, 03:03 PM

you're not getting THAT much more air to get out of the ECU's range of adjustment. I have never heard of anyone having problem from just basic intake mods...

usually those that have detonation problems are either boosted or running nitrous since those devices are trying to get the ECU to dump more fuel than it was designed for...

I would bet Cobb is just playing it safe and covering their azz. They are basically saying a map is good with mods X, Y, and Z. If you use that map with mods W and Z, you broke the rules it's your fault if something goes wrong.

you got one of these in the cab of your car???

DNG35 · 04-13-2009, 03:07 PM

Im'm not changing much, rightn my engine is BONE STOCK, i'm just putting in a ztube and pop charger..should i be affected by this problem?

**thatguy** · 04-13-2009, 03:08 PM

nope .

DNG35 · 04-13-2009, 03:08 PM

NO. thats for sure. i've never even seen one of those.

DNG35 · 04-13-2009, 03:11 PM

ok good, i was thinking to myself , shit i already ordered this pop charger the last thing i want is more problems.

Just use premium fuel and you shouldn't have to worry about detonation. The car has a knock sensor on it to retard timing if it detects detonation, but that will also sacrifice power.

The JWT pop charger and Z tuber aren't going to hurt anything. I have them on both of my Gs along with a 5/16 plenum spacer.

I just called Cobb and they said that the Ztube should not change your A/F ratio that much. Don't have to worry about detination. They said to watch the live data screen with A/F ratio and make sure that it stays between mid 12 and high 13. I also asked them about a plenum spacer and they said you would have to get a pro tune because it would lean it out, but they said that a plenum spacer wouldn't do much for the car anyway. Good news for me cuz I just bought a ztube on ebay!
