Its a flash, right? You can address open and closed loop with a flash. Just change the lambda targets and you are done.
Huh? LTFT/STFT are designed to compensate for variations in the injector tolerances, not change the tune.
If the trims are changing the target values, then you need to go in and change the target values.
There is no reason for the fuel trims to change the base tune unless it was wrong to begin with.

This is easy to explain when you consider that these people have been fiddling with the primary means the PCM uses to determine fuelling. The MAF. If the MAF characteristics are modified, and the MAF calibration is subsequently not correct to reality, then the LTFT's will of course change in accordance with the "error".
In this case youre last sentence is the key. The reason the base tune is wrong is due to the MAF calibration not matching reality. Once enough iterations of fixing the calibration in the flash have been done, and the numbers are right, then there is no need to worry about LTFT's and pulling the fuse. It will soon compensate for injector tolerances over time, as what you would want it to do.
Cheers,
Hymee.

No surprise there, they are Pettit Racing after all. I think it's just easy to take a cheap shot and poke fun at Jeff about his multiple engine failures because the circumstances of those failures weren't totally about pushing them to their limits. That doesn't make it any less of a cheap shot though, and I know I for one am guilty of taking them, but of course, he is too.
I may take you up on that, Charles.

I agree Bas. However, Jeff has been treating people quite well lately and Moon's comment was rather non-sequitur given our line of discussion. Besides, I find it far fairer to just man-up and call Jeff an *******, straight up. I have done it plenty of times on this forum and I am sure he has called me a fool somewhere/sometime, as well. How is it that he and I are still friends despite our differences of opinion on some matters?
BTW, Jeff may not have intentionally discovered certain limits with his accidental dalliances but his sharing of the stories with us certainly provided illumination. Given that some around here think there are "secrets" in the world of performance engines/tuning I am thankful for those who choose to share.
Whenever you're ready I'll take the order!

Unless you've driven that part of the run from Tortilla Flat to Roosevelt Lake, its hard to get a picture of just how extreme it actually is.

WTF? I must be getting soft.
When is it not?
That would be too easy. Besides, that would mean you are accepting my argument and just disagreeing with my demeanor, which no one on this forum (except, seemingly, you) are man enough to do. Everyone wants to bash my facts AND my delivery. I guess that's more fun.
No, not particularly.
Well, blasting up a mountain at WOT and full boost in the summer chasing (and passing) a Mustang is about a legit as it gets.

You're welcome, *******.
(I have stolen that from Denis Leary in "Rescue Me" as that is one of my favorite shows) When I call you that it has no connection to the facts, JUST your demeanor. I am not trying to change minds around here just allow people insight of my own opinions and let them decide for themselves whose views they are most comfortable with.

How does someone giving help towards a shop that is having difficulty with a given issue
Get a jack *** of a response like this? If this is the kind of people who work for Pettit you guys really need to clean house. Regardless of what Jeff has done in the past a comment like this is not warranted especially since all he was doing was trying to help. Given you guys are vendor and this Moon character represents Pettit with his GED-less type posts it doesn't make you guys look respectable at all.

Hit, we didn't spend a whole lot of time on the issue because this has all been discussed several times in the past and it needs no further contemplation. To continue runs the risk of veering this thread off-topic and into personal bashing.

Because Cam doesn't venture out into this medium, he is blissfully unaware of Moon's antics.
I don't think Cam has too much to worry about since most of his bread and butter does not come from internet sales.
I used to think Moon was just, for lack of a better word, "impaired", but I've come to realize he is actually mentally ill.
I really hope the best for him, but stories like his seldom end well.

Is there an updated flash fron Janurary? Cam told me to pull my fuse often--I have an o4. He even put a pig tail on my room fuse to help with pulling it. Its no big deal. By daily I guess I meant I just have developed the habit of doing it every day. A fellow member even came up with the idea of putting a switch on the room fuse to make it even easier. Better safe than sorry?
I have modified the rb maf pipe/horn, filter(not the box) and CAI collector to fit. I use screen just slipped over the end. One hint --- dont tighten the intake hose to tight as you start to warp the screen/alignment of it all.

Its all the same. Air is air.
Flashes (like the OE programming) utilize load-based tables. They don't care where the load came from.
Boost varies with a turbo exactly as much as you use the gas pedal. Its no different than N/A.
Its the S/C that has a weird air-mass delta since its pumping volume doesn't respond to throttle input like it does in the N/A application.
That is such an outrageous requirement that I don't even know how to address it.

I don't really have a problem with that...I just finished manscaping the lawn this morning too...and started to contemplate getting into ****...I would take one hell of a pay cut...but I hear the benefits are fantastic...
Heh the funny thing is...you should see what I do to people in real life...some of my best work is not on the internet...and probably involves several felonies...
*sniff*...good times...good times...

MM- Moon isn't a representative of Pettit.
Moon- Not at the moment but im going back in March fullltime. So your right about that.
MM- Because Cam doesn't venture out into this medium, he is blissfully unaware of Moon's antics.
Moon- My antics are I cant stand you personaly because when I first got on the forum you made a wrong assumtion that I wasnt involved in the R&D of the kit, blasted me for it and for some reason or another you got racial with me and I dont play that crap or forget.
MM- I don't think Cam has too much to worry about since most of his bread and butter does not come from internet sales.
Moon- Not true, its funny how many people call Cam calling you a ****** while placing their order.
MM- I used to think Moon was just, for lack of a better word, "impaired", but I've come to realize he is actually mentally ill.
Moon- Yeh, ive been accused of that before, been called nuts a few times, off my rocker, but you now what, lifes so much more fun that way.
MM- I really hope the best for him, but stories like his seldom end well.
Moon- no you dont, your so full of chit DR Phil
And as for drugs, I havent taken anything stronger then advil since March, last year, your attemting to take a stab at my credibility once again.
