Well i got a great suprize checking my email today around noon. Dropped everything i had to do and loaded up my tunes. Since I had 87octane in the tank i loaded 87 performance. Wowzers it's pretty damn nice! This thing is not overated. Havent gunned it form a stop but since it chirps from 1-2 i'm pretty sure it'll do a nice burnout. The shifts feel like i have a shift kit!

I do have a question. At about 30mph roll when i gun it, i feel some major torque and even sometimes make the tires chirp. But from around 40mph it's a whole other story, it dosent wanna drop a gear, so acceleration is much slower, is this normal? maybe 93 performance is diff?

I've read somewhere about a guy having problems at abou 40mph, i wonder if im in the same boat.

Sorry 1 more question. When racing do yall completely manually click OD off and race? Or do yall maybe click it about 40mph?

Obviously a noob, any help would be great, flaming would not be helpful.


TROYER TUNES ROCK

 

Nice.... can't wait to get mine in.

So does Troyer send a blank tuner right away and then the tunes later?

 

I don't click overdrive off to play...do click overdrive off you you are in overdrive and want do nail it... if you don't it will do a 4-2 downshift and if very hard on the trans...

most trans will not (including mind) downshift from around 40 or so... thats why I don't like to play in that range, get them earlyer all a lower speed or let them go and play at the next light when you can lanch in a lower gear...

see if they really want to play, they will be there waiting for you with that big " I know i'm going to smokem grin" and you can watch it fall off there face as you go by....

If you thank 87 is killer, wait intil 93 is loaded.... you will forget all about 87 and never load it again...

 

Thx for your reply. You answered my questions very well. You got me even more excited about 93 performance! I'm goin crazy about my 4.6 waking up, i cant imagine what it's like in your truck!

And yes, troyer sends a blank xcal2 and emails the tunes.

 

Hi.

I've always, by default, turned off the OD upon start - just a habit I got into. Mostly city driving, so OD's pretty much useless to me in that situation.

Additionally, I've found the same sort of issues around 35-40 mph. Part-throttle (say 30%), 5% grade (1 mile long), while climbing it, goes to third and TC locks and stays locked, with a lot of pedal required to unlock and accelerate if I need to.

What's really intriguing is, I can press the OD button (to re-engage it) and the tranny promptly unlocks/downshifts - no change in throttle position by me. Pop the button off again, and after a couple seconds it upshifts/relocks. Rinse, repeat, and so on.

So, at least in my strategy, (TEJF4P5) there appears to be some interaction between the OD input and shift schedules - and I stress *appears*, since this is not a scientific or controlled test. It is, however absolutely repeatable, and given the length and consistency of this grade, I can do this several times on one ascent.

So... I'm thinking there are some datalogging parameters I could capture to help me understand this behaviour better - I'm thinking Load, Throttle Position, Rpm, Spark Advance, Vehicle Speed, and maybe MAF counts. I'm gonna try to do this soon, just for curiosity's sake.

And no, I have not yet submitted my formal datalogging for the tunes in general (clock is ticking I know - no TIME), and I don't suspect there's really anything wrong regardless.

I ain't smart, but I'm always curious, and yes, like the cat, it will probably result in my demise

Cheers

He sends a blank tuner right away when you fax your sheets in? I don't know about that, I faxed mine over 3 weeks ago and I don't have a blank tuner??? Are you sure about this?

Well i went to go test 93 proformance, and wow i think there is a v8 in it now. Kinda wish i payed more careful attention between 87 performance and 93 performance. I know 93 is better, but im still determining how much better.

Kinda wierd though, when i first installed my tunes, evertime it shifted between 1-2 it chirped the tires. About a 30mph roll if i floor it it downshifts and chirps. Dosent do it anymore, did my truck "learn" my driving?

I kinda liked the 1-2 tire chirp. Tells me theres some tq going on .

If you dont have a Xcal 2, call mike already, you wont regret it!

 

Ordered mine on Monday, can't wait.

 

Mike will send out a blank tuner if you don't know your PCM code or in some cases where you have had it reflashed at the dealer and he wants to make sure he has the correct code. So, no..not everyone will get a blank tuner right away.

Thanks, that's what I had originally thought but after seeing a few posts I was starting to question it. Thanks again.

 

yes, thats adaptive staregey at work... the power is still there and a little more as it learns... it learning your driving habit and the engine fine tuning from sensor input... may take it a little while, say for the first 150 to 200 miles...

it will learn the way you drive... drive it hard, it runs hard... drive it soft, it runs soft.... but a few WOT will tell it that it needs to wake up.... this is why when most people run a street driven car or truck at the strip, when they get there, they disconect the Bat and make 1 or 2 passes before running...this clears the adaptive staregey and teaches the PCM to run and shift at WOT....

 

Great reply. Answered my questions pretty good. So should i disconnect my battery before i go hunting for a race?

I raced a 5.3l chevy with a drop in k&n on 20''s. He had me by a truck length at about 70....Kinda dissapointed with my mods vs his. I think i'll def be able to take him when i get my 4:10 gears in.

Get your troyer tunes already if you dont have em!

 

HI Beepers,

One quick comment - when you nail it from 30 mph, it will still downshift all the way back into 1st gear - but when you nail it at 40 mph, it will drop back into **2nd** gear, it's too high to go all the way back down into 1st gear at 40 mph, that would rev the engine too high.

So the thing to remember is to get used to the shift schedules, and know at what pint you can still get back down into 1st - now at higher speeds, the same thing will happen -meaning, at high enough speeds, it won't downshift into 2nd anymore, it will go down into 3rd (from 4th)instead - this is exactly how it should be, as the powertrain has to be protected from overspeeding, or over revving the engine.

That means that at some points, when you downshift it will rocket away - but at other points, you'll be caught at the bottom of the power curve like you are when downshifting at 40 mph - you end up in the lower part of the power band in 2nd gear, so it doesn't pull as hard - so you have to get used to where it makes it's power, and at what speeds you will get which gear on the downshift, and get used to it - this happens in all of these vehicles, of course. Now in most cases, we will let it downshift at a little bit higher speed in each gear, but we still have to protect the powertrain, so this is always going to be a factor.

Just FYI so you know.............

Enjoy your tuning,

 

Just another reason for Ford to get on the ball and offer us a 5 or 6 speed auto tranny.

 

No he does not do this. He only sends a blank tuner if he thinks that the PCM code is different than what is on the door. He then has you read it and send it back to him and then he does the update to the tuner and sends it back to you.
