Hey y'all,
I keep getting a P0131 code on my 2011 GT500 and I was wondering if anyone had experience with this?
I have replaced the b1s1 O2 sensor, but I still get the code! My next step is locating the correct pinout procedure to determine where the problem lies. I believe I need pinout...
OK will do. Any idea where the knock is coming from? Exhaust looks good, no rubbing anywhere. Also the same amount of knock behavior is present whether I put 100 or 91 in with the current 91 tune lol
So with their tune there should be zero knock, even with 91 octane in the tank and the current 91 octane tune loaded.
I can understand why they are taking a safer route.
Thanks for the info fullboogie!
Merkyworks,
I believe my issue is false knock. I agree the timing is low though, remember I am running a 91 octane tune with 100 octane fuel, to attempt to confirm my false knock theory.
I very much appreciate your input and stats, thanks again!
Hello Everybody,
So I took some of yall's advice and here are the most recent steps taken and the data log results:
1) Switched to a PMAS 120mm CAI
2) Got a revised tune from Joe @ VMP for 91 octane
3) Ran the car to 10 miles till empty, put 5.5 gallons of 100 in zee tank
4) Re-loaded the 91...
Thanks very much for the information everybody! Every little bit helps me put the puzzle together.
I had some time to do a little more data logging today, this time I added 4.2 gallons of 100 octane to my 11.8 gallons of say 90.5 octane (which I feel is an accurate representation of a month's...
Hey y'all,
I went ahead and did another log. This time I was able to go to redline! Please take a look and tell me what you think! Your analysis will be greatly appreciated as I am trying to learn about tuning these cars. Once again this 3rd gear pull was performed on 55 degree day @ 3,100ft...
I'm afraid the reality is not as entertaining as the current perceived understanding.
I typed up a post named, "A/F Ratio and lambda with different e10/e15 fuels", but the title somehow got changed to '!'. Therefore, I deleted contents of the posting and simply typed, '!' in the postings content...
Howdy y'all,
I am trying to do some learning on how A/F ratios and lambda are affected when using fuel with different ethanol contents, i.e., e10 and e15. I have pasted some AFRs according to fuel with differing ethanol contents:
Gasoline(Petrol) = 14.7:
E10(10% Ethanol, 90% Gasoline) =...
