Well don't take my word as the final say, but what manufacturers suggest doing from the factory is getting enough gas at the lower octane to cover you until you can get to a station with the appropriate octane, then fill up there

Lets say in an F/I app. you have the car tuned for 93/94 octane, you fill your car up with 91/92 because the gas station your at doesn't have 93/94. Do you have to redo the timing/fuel maps you set for 93/94 for the lower octane level, or will the car run just fine?, can the piggyback or ECU/standalone your using compensate provided you have all the right sensors, A/F targets set, and etc?. Thank you.

If your car is tuned to that octane level, and you add a lower octane your asking to break something. Your car will abnormally start knocking/detinating (sp).
Lets say you burn up a piston, and the shop that tuned it discovers you put in the wrong gas your SOL. :thumbsup:
Most good tuners will tune your car as a daily driver. Meaning not fully maxed, just for your own protection.

KShep, Do you have mulitple maps stored on yours, and how hard is it tune/switch maps

About the J&S. If your Piggyback/Standalone is already detecting knock and starts to pull timing, will the J&S interfere, and posibly cause problems?. And what would happen if I fill up on a higher octane 100-110 on a 93/94 tune?.

How much boost can you run safely on 92 octane gas ? And how much timing retard would you run for 92octane for each lb of boost on ?

I would concider the F-Con but I'm not a pro dealer, nor do I plan on visiting one every time I want to tweek something

Not true. If you bought a HKS F-CON V PRO or HKS F-CON SZ you can use the navigator to tune it. Not as elegant as a laptop but it does the job

I was just talking to a frined of mine, and he said Chicago has 93. So now I ask this. We have 94 here in SC, and if I fill up with 93, will that make any difference. I would hope not since its only one octane point, but you never know.
I like the switch idea for good gas and crappy gas. But with the J&S if it picks up on detonation, and doesn't pull timing till the next firing sequence will it only pull timing every other time in the sequence, or will it just pull timing till it thinks the detonation is gone?.
Sorry, I just need to pick someones brain
