No 93 octane around what to do

[9daysbefore]

Nobody around my city carries 93 octane anymore. They do carry 91 octane though. If I were to have a chip burned for this octane would that be OK to run or is the lower octane too much of an issue? I hope not - over wise I will not be driving the car. Please let me know your experiences with this.

Thank you,

you run what you can buy...probably have to reduce the boost a couple of pounds if it shows any timing retard.

Lotsa people now run alky injection so they can run a lot more boost on whatever gas is available.

I've updated to a 3.5 Bar Map, and playing with more boost.
0-60 times in the mid 4's.

As far as transistional knock, which was mentioned in that other thread, that's what your Burst Knock Retard it for. When you hammer the gas the BKR drops the timing slightly, and then adds it back in. Just another tuning item to consider, tuning.

While just a low boost run, it is for 20 secs., and there was no knock, and the car was pulling smoothly without any sign of misfire.

206/206 roller cam, F/M, Razor's alky kit, my own reworked TR ecm, and code, lots of hours tuning using a WB, EGT, scanmaster, and datalogging.

Yes, my results are not typical, but the level of attention to detail given the code, and time tuning aren't typical.

While I've picked 87, and run it successfully, it also indicates, that with a lesser amount of work, that the same results can be made using 89, or 91.

Being able to add some boost, by adding alky has been proven. While you'd need to lower the boost to run 87, by adding alky you're able to maintain, if not still slightly increase the amount of boost (and possibly timing) you can run.

The enclosed datalog is *low timing*, in that, I was still working on the new tune with the 3.5 Bar MAP sensor. I'm kind of old fashioned in that, when I make a code change I back the tune way up, and then rebuild it from more or less the lowest tune possible.

And FWIW, please note, I provide datalogs to back up *my thoughts*, while others rely on speculation and *thinking*, rather then actual testing.

Just back off (assume adj. wastegate) boost about 1-2#--until knock/ KR gone, or add alky, or add some other legitimate octane booster (xylene, toluene,,,)
