Tuning Question (Alky and 02 reading)

[rssooner]

I need some input please:

I am running alky with a TurboTweak chip and I have been to the track now twice since I have installed both. My turbo link shows the 02's are between 770 and 820 during WOT at 24lbs of boost. I have had no knock what-so-ever and it shows that I am running rich. I have been told that 02's can be "misleading" when running alky. I was also told that 800mv is a safe conservative place to be. Any advise on this would be much appreciated.

Thanks in advance.

as to it saying your running rich ,you should be rich under boost at around 12:1 , what your seeing when you look at the screen and it shows the 'rich' flag thats the ECM commanding the fueling to be rich , thats the flag your looking at not a condition returned from sensors but a call for an action
when you cruise the flag flips rich/ lean as the ecm adjusts back and forth

770-820 (should show 820 and goto 770 during the run) is fine for O2s .

Well what did it run versus the buildup and boost level?

If you think it's rich you can up the boost 1 psi. at a time until you see some KR.

Seems normal so far for the data given.

An EGT meter would give you another reference point also.

Look for MPH increase from 1/8-1/4 and tune for most MPH increase. low 12 second car about 22. Low 11 second car bout 25. If you lean it out a little and the mph goes down.. your going in the wrong direction. Then try and richen it up.. see if the MPH increases.

Do a few passes without making changes to get an average. make a change and do a few more passes.. see if the results payout in MPH increases. Dont worry bout ET.. yet.

Sounds like it could maybe go a tad leaner.. but the ET slips clearly will show if your making power.

I ran a 7.56 @ 91.5 mph w/ 1.66 60ft.

I have a TE 60 w/3200 stall, 50lb injectors, etc.

Thanks for all of the help.
