Bad Gas?
G'day Folks,
I've been using Shell V-Power (98 RON) since I've had my car. Lately, I've been learning to read the logs from my JB4 and discovered there were pretty severe timing corrections (first log) likely due to poor quality fuel. As an experiment, I added 1/3 of a tank of E85 from United Petroleum to raise the octane. The results show a better timing profile with the E85 blend (second log). I'll fill up at BP next time and see if BP-Ultimate works any better than Shell. Logs were collected under MAP-1. Another option is to try an Octane booster. Has anyone done any research or testing with these? Ken

I've no experience with octane booster and have read mixed reviews about them. Interested to see the results with BP. Though there are too many variables to control for, it'd be interesting to see a comparison between the different servos

It's more likely jb4 is doing this to the car? I've read there's a lot of inconsistencies with it... might be wrong tho

Our cars are very similar but you do have a lot more hardware haha Wagner Competition IC | Wagner Catless DP | Evolution Raceworks IC Pipes | Dynan CAI!!! I'm surprised you haven't gone for a proper exhaust and a proper tune... any reasoning?

I don't know enough about a "proper tune" vs the JB4 to comment. What are the benefits of a tune?

As for the tune, a "flash" tune is a proper tune, while jb4 is a piggyback which "trick" the engine into thinking something that's not. Flash tune is a lot more consistent and gains are more (mate switched from jb4 240kw atw to flash 267kw ate)
