Use window washer fluid...

Splash is my preference. If you add 3 bottles of heet it should be 50%.

I thought about that .. but i want a abnormally high octane ratio.  Then if it stutters at all its not the issue for sure.

[polskifacet]

Hmm spraying fixes my shitty fuel pressure with 30% so 50% should be ample. you can also use ethanol.

Ethanol: It is not as good as methanol, but it can be used as a 2nd best option if you can't find methanol. It can also be mixed with water up to 50%

I doubt octane is your issue. As AJP stated... your logs didn't have enough knock to cause your problem. It's your money obviously... just trying to save you some trouble.

So here's the nutty thing ..  after hammering on it  with 97 octane the issue is there but to a much lesser degree.  This is ethanol free 97.  I need to drive it more to make sure it's not a fluke

Bought COP boots, and the windshield puller bit.  I will examine the pcm this weekend.

I'm going to make a new configure file to double check the Miss fire counter.  I'm also going to hunt down the ethonal counter.  The lamda/lambse thing looks fine but worth a look

I'm going to pull the front bank of plugs and inspect them .. if there remotely yucky i will pull them all even thought it is such a pain in the ass.

Updates letter ..

That is kinda good, but tells you octane is a bandaid.  Was OAR Learned before you put the hammer down?

That's a great link!

I have my tuner in my hand.  i did the pid validation again .. built a copy pf brads log.  added missfires. 

I am afraid to look really.  if its not misfires i have to make a 600$ guess on option-a or option-b and live with the results

[StealBlueSho]

I mean... I wonder if the LMS tuner I have will work on yours. They require the SWPN so I am not sure if their tunes are tied to that AND the strategy...

I would honestly revert back to stock, drive it for awhile, and see if the issue persists. If it goes away, and you are interested to see if the LMS tune is a better fit, then I will ask them if you can use mine to verify...

Assuming that option A for $600 was to try LMS...

No misfires.  the tranny log with misfires was a bad reading. and it was  a classic bad run.  end of third was choppy stutterer and full of random power drops.

well s***.

-gamble on a ECU as the last money i can spend
-gamble on livernois as the last money i can spend
-save 600$ and go stock and sell it in 9 months.

i'm off for the night. time to drink a few round and get away from this mess.

Thank you for the offer SBS.  I will consider it.  I am going to go back to stock and drive it for a few days.  Lets see if the issue stays 'gone' for that longer time frame.

I still think he needs to run that stock tune for a bit.... but talk about persistence Z!!!!! Guys like ZSHO are the reason this forum is the best one out there. Remind me to buy you a drink (even if it's lemon polar) when I see you at Cecil this coming season.
