Code - H30F1 on Cobb AP v3
Hi all. I have looked everywhere on the forum about this code and found little information.
I checked the cobb codes and found H30F1. That's the only code I have. From the search I did got the following: Glow ignition: cylinder X EXPLANATION: Super Knock in cylinder X. FIX: Excessive knock retard. Lower boost levels, or run higher octane. I pretty much understand what it means, but the thing is the following. Apparently the knock is not persistent as the code has not appeared again after I cleared it and did some runs. I'm running stage1 aggresive from the Cobb, always using Shell 93 from the same station and even the same pump. Otherwise the car is stock. I have the feeling I might got a bad batch of gas or should I downgrade to stage1 sport?. Plugs & coils are about 8k old. Been using this map for 2 months already. I'll keep an eye to see if the code comes back. If someone run into this as well, I appreciate the feedback. |

on a precautionary basis I went to Stage1 Sport map on the Cobb. Will make some logged runs on this map and some on the Aggressive one and try to analyze them. Finally as I have a full set of new NGK sparks I will take them out to have a look at them.
