Thanks for all the guidance, guys.

I paid $7.50 for the 100 octane.

 

ELMEL,
I think the gas station at Suno is usually 6.xx for 100 oct.

 

hahah good job ELMEL

 

Suno? Where's that?

 

The station off Andrade (spelling??) off I-680. Pump #10/11, I believe.

 

I felt the impact when stock- much more significant with the UMW tune.

Although I have a 100 octane tune, the regular UMW tune shows DRAMATIC improvement with even 50-50 100:91 (cali crap).

As mentioned above, the DME will pull timing with 91 octane, even more in the heat- 96 octane just results in less pull.

All (decent) programs have the ability to adjust to some degree for varying octane- I believe even the stock. I suspect, however, that once you get past 95 or so, the stock maps cannot wring any more benefit from the octane.

(ELMEL- Woodside Road, 76 station, at the pump- $6.59 I think?)

 

I have an addiction to MS109 like it was crack rock.

 

Eugene, what town are you talking about? I even went to the Conoco Phillips web site and can't find anything that looks like Suno or Andrade.

 

Forget it. I found it.

Sunol Super Stop
3004 Andrade Rd, Sunol, CA

Here's the Google map.

Thanks!

 

Glad you found it! Left out the "L".

 

Well it doesn't help that I'm dumb. I had no idea where Andrade was. Just down the road from me too. Not very observant, I guess.

 

I have UMW's turbo's and tune (well currently working on the exact tune, not done yet). Anyway, I was logging some pulls to send to UMW with 91 octane crap gas in Denver. I was told that the DME is pulling timing because of the fuel. So I decided to add about 4 gallons of 100 to the remaining 12 gallons of 91. The difference was huge. It basically only brought the octane level to 93, but that was enough for me to physically notice the difference. Probably going to more may not have made the difference but the DME is not pulling timing to save the engine so it definitely works. and this was not even the race file.

 

bingo! it is software related and "certain" programs do adjust the timing etc to the octane presented.

I dont need to change from program to program at the track just put 112 in and let er rip! HUGE difference.

correct software is the answer, a stock car or an ECU not tuned to higher octane you will get nothing out of your coctail.

 

Hey Mr Elmel I guss you are the other s hardtop guy in th bay area. By the way any of you all from north cal going track day on 10/31. Eugene what about you.

 

Hey Donny, haven't heard from you for awhile. How's your TTS running? I still haven't yet been to a track; haven't gotten the permission from the "boss" yet.
