Beefcake nailed it!!!!

 

So somehow your "flasher" defied the God's of physics and breathing limitations of the Cobra motor, and managed to produce increasing power gains up to 6900? Impossible! The internals and breathing capabilities of that engine with the stock blower, even with exhaust modifications, will not make peak power much over 6000, even with the best of the tune. I'd really like to see your graph just to see what is going on there.

6900 plenty high? I'd say so! You shouldn't spin that engine past 6500, regardless of how strong it is. It wasn't designed to run past 6500. Shifting it at 6500, however, is safe as well as the best shift point for the Cobra, and one should have their rev limiter moved up to say 6800 to keep from bumping it during power shifting.

As for the afr, well, although that's safer than stock in the lower rpms, it's a bit on the high side to my likings, but you should be fine there, being that you have the stock boost level.

You'll QUICKLY see that this will not happen. You're going to run lean. You are risking a 12k motor, and it's NOT worth it. You're on the reflash bandwagon now, and it's going to take a few bad dynos, or a few blown motors, from individuals on the same lead, for many of you, to understand how the pcm works.

These are the standard #'s that any Cobra would make with just a Magnaflow X-Pipe, and Catback, even without a chip or reflash. I wouldn't brag too much here.

That thread is WHACK! Read my info. I just posted there:

https://www.f150online.com/forums/sh...10#post1003410

Also, there isn't any difference between the Predator and the method of flashing you had done, save for the file programmed by the tuner. As for the difference between chips and flashing, again, they are the same difference.

 

You guys have been looking for results on this and the results are being shared with you. All Onefastlride did was produce results with a rock steady A/F. And an A/F that will stay that way given what he has planned for the car. Many claimed it couldn't work, yet in the face of this you still claim it won't. The numbers he provided are real world numbers. No cool down of the motor took place.

Believe, or don't believe it. It's your choice. If you think the way a chip works is the same as the reflashing being discussed here then you clearly either A) don't know any better, or B) are being fed bad info.

I am sure there are others reading this thread that are bright enough to think for themselves rather than listen to those that give no rationalization as to why this can't work. Hopefully you find this info helpful. I know I have found this entire process to be very exciting. Of course, I am sure the tuners are less enthused.

Right Beefcake?

A) You obviously know NOTHING about the reflash process and its capabilities. Go compare the AFRs of a chipped truck and a reflashed truck and you'll see the difference. Why is it that chipped trucks sometimes require "warm weather programs" and "winter programs" to prevent running lean in the winter when a strock truck does not?

B) No one was really bragging. There was earlier speculation on the results of a reflash and a member simply posted dyno numbers for those who were interested.

C) I'm seeing increased amounts of Team (insert vendor here) members coming into these threads to bash reflashing. Seems to me like you guys are all a little nervous that maybe your "tuner" doesn't know everything and their "tuning" technology has become archaic.

 

Ding ding ding ding. You are correct sir.

Although I would've gone to someone outside of the "mainstream" Lightning vendors had I stayed with a regular chip, I know some other former chip customers are intrigued about this reflash stuff. And it's simply a matter of economics. There's only X-amount of Lightnings and 03 Cobras in the Ford performance community, and with the growing popularity of a new venue of tuning, other businesses will see decreasing sales.

Oh, and word on the street is that the reflashing guy is someone who has refused other supporting vendors on here.

 

Yes, that is an interesting question - isn't it?

Jim

 

Looks like youre another one of those cheerleaders. If you dont think you can spin a stock cobra motor to 7000 rpm, youre completely stupid. Older cobras spun to 7,000 and ford dropped the max rpm's down to keep from over spinning the blower. Please do your research before spewing bad information, it makes you look like a fool.



Please tell me what makes you an expert on cobras? I find it rather funny all of a sudden 03 cobras comes out with a blower and these experts cropped up after midnight. Give me $1000 and a set of cobra heads and you will see 7,600 rpm shifts.



High side to your liking? Ford runs both the slobras and Lightnings at a VERY conservative A/F. 12.1 is hardly high from a tailpipe sniffer. It can be anywhere from .4 - .9 points off on A/F... Theres also more then just A/F's to be concerned about. You could have a car making a 11.3 a/f all through the powerband... if you go to aggressive on the timing, " KABOOM ".. now what? Whoops, paid to much attention to the a/f graph during the pull and werent paying attention to the power were you? I get a good laugh at postings like yours.





Would you like to put your money where your mouth is? Go grab your pom pom's.



Ask him where he dyno'd at first.. Dyno #'s mean jack, bring out the ET's.


After reading your comments here, you have nothing to add. There is nothing coming off youre keyboard that supports your silly claims or EXPERTISE. Run a long now and go read some books.. Basic fundamentals of forced induction would be a good start for you.

Oh reallllllllly. Ok genius.. You just placed the nail in your coffin and demonstrated youre complete lack of knowledge of this said discussion. Buh Bye now.

sorry, you set youself up for it.

Skip, what exactly did beefcake nail? Why don't you explain. Beefcake, you too can explain to us. I'm sure you have some undertstanding of how a PCM works and a reflash? Tell us how. What, you going to call Sal? He burns chips.

 

So you're saying with the flashed program he has, he can add in a 6# pulley to his Cobra, stay with that same exact program he has now, and his afr will stay at a rock steady 12:1?

I could take that flashed program and convert it to a file for a chip, and it would do, yes (and again), THE SAME THING! And vice versa, I could take a file from a chip and convert it to a flash file!

I can't believe you are falling for this. I could flash you a program with the factory timing and fuel and you wouldn't have any problems in the winter (or summer) either. What tuner is going to write a file with the factory settings? The timing maps can be dialed in too high (or low), and the fuel maps can be dialed in too lean (or rich) on a "flashed" program as well. You aren't making any sense.

I never said that you couldn't spin the motor that high. I asked him a question: "managed to produce increasing power gains up to 6900?". Read the word "increasing". There isn't anyway he made peak rwhp at 6900 with his given mods!!! And, Ford just didn't lower the rpms because of just the blower. There were other "internal" factors taken into account when they did this. This motor is not exactly the same as the pre-'03 Cobras you're spouting off about.

Regardless, there isn't any reason to spin an '03 Cobra past 6500, period! Peak power with the factory HEATon is approx. 6000 rpms, and even with exhaust work, intake work, and being pullied, the components of this particular engine still do not make peak power much past 6000. The proper shift point, however, is usually around 6500, so you will get your best area under the curve for the next gear. Throw a KB on this particular vehicle, and the situation can and will change.

Yes, to my liking, just as I stated, and I told him he should be just fine there where he is now.

Naturally!

Cobras come relatively safe from the factory at around 11 degrees in the lower rpms, and increase steadily to around 22 at WOT. The main power gains on the Cobra come from fixing the afr in the lower rpms (too lean), and in the upper rpms (too rich), plus increasing the lower rpm timing curves to maximum overall torque and horsepower. There is normally very little upper rpm horsepower to gain from a new tune on a Cobra, unless the calibration is so out of whack for the given mods.

 

So basically your admitting you really dont understand what a reflash is. Great, Thanks for the clarification.

 

This alone shows you know nothing about what we're talking about.
Scurry back to your "tuner" and see if he can provide you with some better comebacks. You getting owned is getting old.

 

Ok, this is getting a little ridiculous. You have no comprehension of how this works. And you clearly don't undertand the limitations of a chip.

I'm not sure anyone can convince you otherwise - for whatever reason. I think you know the truth and have a separate agenda.

The dyno results have already been posted. Either that is good enough for you or it isn't. But in your case, I don't particularly care either way.

Best wishes.

Jim

 

Regardless of chips or flashing, I still want to know if anyone actually believes this is possible with the stock engine on the Cobra (regardless of exhaust):

 

Oh please explain it to me mighty new Diablo dealer. I would love to understand and learn from you, the God Almighty! Please?

 

Diablo dealer? WTF?

First and foremost, im not a dealer. Infact, if i was going to be any kind of tuning, it would be with my OWN software and hardware. I am Not and NEVER will be a vendor. Dealing with people like you all day would drive me nuts.

If you would like to learn from me, i could probably educated you a lot more then your mentor.
