FYI for those with 05's
 

Thought I'd pass on a little info for those of you with 05 F150's. Mine has always run pretty well on the stock tune and had none of the throttle lag, slow shifting problems we've read about on here. I have had Mike's x-cal II for about a year now and overall I like it. Much more power at wide open throttle and my only dislike was part throttle driveability. I work at a dealer and was talking to my shop foreman the other day about a checking for any updates to my stock program...computer code TEM5. Sure enough there was one in the system so I took a chance and had him do it knowing that my x-cal would have to be re-done. Well the end result is :eek: . The truck runs like a stripped arse ape on the stock tune now! My butt dyno says its as strong as the tuner on the 93 tow tune! The truck literally has NEVER run this well in any form. Those of you who don't have a tuner and have the TEM5 code computer you need this reflash, trust me. The part # it gives you when downloading is 5U7A12A650EBA. Just thought I'd pass the info along.:smoke:

Is that only for the 05 models? Any one know if it would work on a 06 4.6?

I'm sure this particular reflash is for that tem5 code only.

how about TEM7 (stickered) but in actuality I was a BKP1 4.15.05 build date
sooo, you've got to get re-xcal-ed now?

is there really any benefit to being dealer reflashed if you are going to wipe the stock tune out for troyer's tune?

Sounds like what happens right after you disconnect the battery. :lol: Too bad now you have to get your Xcal2 re-tuned. :p

BalogUK, disconnect your battery for about 15 minutes and see how it works.

-good call thump- not a bad idea at all since i've been running 91/93 max all summer, and now im back on 87 max for the winter--let the pcm adjust correctly for the 87 tune, and break the habits of the 93...




EDIT :30 minutes later...

Thumper, that was quite possibly the worst suggestion you could have posted :devil: My truck and I thank you...
the corner of remington and 19th are now marked with the distinctive tread of my xterrains, and the smell of burnt rubber. damn- just when i was getting over the "drive like a bat out of hell" virus...
:rocker: Justin

All that happens is that you got updated to BKP1 - you didn't get any more power at all, all that happened to improve anything was the act that in the process of updating the PCM, you wiped out KAM, and thus cleared out the adaptive strategy adjustments.

There isn't a anything better in BKP1's engine tuning than is in TEM5, other than at extremely light throttle (below about 13% TP), BKP1 commands slightly more torque - nothing else, period, end of story - I have both codes opened right now, and of course, already knew both of them extremely well having tuned literally thousands of them. Nd thanks to the changes we made in our tuning, you didn't gain anything - it just feels peppier now simply because KAM was cleared, meaning the existing adaptive strategy adjustments were cleared out - and that won't last long. You could have done the same thing by simply disconnecting your battery, only you would have had MORE power, and much better performance because you would still have had our tuning. :)

Additionally, you have also lost your performance tuning, and whatever you do, DO NOT ATTEMPT to reinstall it, as the Equizzer ID is different - so what will happen is you will get a no-start - and then when you attempt to return your vehicle back to stock, you will be returning it back to the OLD stock tune, TEM5, and it STILL will not start - it will have to be towed back into the dealership and reflashed once again. Now you can unlock your tuner, so that it downloads the NEW stock program, but then it will not allow you to UPLOAD your old tuning in most cases - and even if it does, you will still get a no-start, and have to return to stock.

This update didn't get you anything other than losing your performance tuning, is the actual bottom line, as we rewrite those ETC areas anyway to give better throttle response - so the reality is, the net bottom line is all that was accomplished was clearing adaptive strategy and losing your performance tuning.

But as long as you are happy, then we are happy for you. :)

And by the way - no, this code he is talking about CANNOT be done on ANY other vehicle other than the TEM series, which would only be a very narrow timeframe of 2005 5.54 3V builds - and should NEVER be done by anyone who has our performance tuning, as it will NOT gain you anything, regardless of anything being claimed - that is the simple reality of it. If that were true, then our performance tuning would actually be REDUCING POWER - and we all know that isn't even remotely the case.

Well I'm one of the Tem guys who reflashed a long time ago actually to the BK code from Ford. Sure when the dealership first flashed the truck, the performance for a day was NUTS. I couldn't get the grin off my face, as it ran SO FAST IT WAS INCREDIBLE.

HOWEVER

Three days later it was just a little better then what it was before the reflash from Ford. It had lost the complete haul arse spirit that it had directly after the flash, but at least it was better then it was before.

My 91 tune gives me close to the feeling right after the reflash, but at least holds that feeling after adaptive strategy.

Good idea pointing out to stock guys though, that a reflash from Ford can help them if they cannot afford custom tuning.

So, out of curiousity here, is it just with the TEM* coded F150's that will run like no other when you disconnect the battery? Or do all F150's do that untill they re-learn adaptive strategy?

Am I safe to say you could do a little better in a race or something by disconnecting your battery beforehand, or am I way way off base (most likely lol)

bartak- it wouldn't be held to just the TEM's its the nature of the pcm and as Mike said the KAM- you've cleared the adaptive strartegy of the pcm, its a clean slate, and responds like day one again- hence my EDIT: 30 mins later post- i just disconnected my battery to clear my pcm- reconnected about 20 mins later with troyer's tune installed
:thumbsup: J

Hehe, sweet :D

Same thing when people reflash with a new performance tune. They jump on here raving about it the first day before the adaptive strategy adjustments take place. It feels like it's doing a whole lot more than it is. :thumbsup:

Well I appreciate all the replies, especially from Mike T. The reflash has been in for several days now and about 1000 miles. I've read all about the adaptive strategy on here and I can tell you the truck feels just as good now as it did when first reflashed. I pulled this 4500 pound trailer to the Texas race this weekend and it felt like it weighed half that much. It walked up the hills at 70 mph on the cruise and never lost any speed at all! Mike is exactly right about the light throttle torque being better, thats the first thing I noticed. Didn't mean to start a flame war over this, I am just very excited about how well it runs on the stock tune now. I'm sure I will get my x-cal redone down the road and see how it feels then. My main reason for posting was for those with no tuner, you will love the way your truck runs on the update. I would think after a 1000 miles the adaptive strategy would have softened it up if it was going to but it has not. https://www.f150online.com/galleries...155-173110.jpg

Hey, I appreciated the post and what you are saying. You know your truck is performing better and just trying to share. That's great info. You got your race in, turned out pretty good didn't it?

Thanks Jim. Yes the race turned out pretty good even though the Ford's didn't do too well.:( What was crazy was how nasty the weather looked all day yet they had no rain delays! :D
