Just picked up a Hypertech power programmer lll, what is the best all around set-up for this truck? What is the rev. limiter and shift points set too at stock? Searched my owner’s manual and found nothing giving me this information.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

Any info would be appreciated.<o></o>

Thanks to all.<o></o>

The rev limiter should be set about 400 rpm above the highest shift point. It will limit your revs and save your engine in case the tranny blows. Most people I have seen here set their WOT shift points around 4800to 5100 rpm. The 3-4 shift should be lowest since that is the weakest link in the stock tranny. I think the WOT stock points for 1-2, & 2-3 are around 4750 and 3-4 at 4400. Play with it and see what is best for your set up. Be safe tho.

 

thanks for the input, and as always any more is welcomed.

 

ive got a question about this also. but i have the sct xcal 2 and a buddy of mine has the livewire on an 06 fx2. why can he rev his 5.4 out to over 6k and i can still only hit the stock limiter of about 5300. i could rev my 4.6 out to 6200 with no problem, i understand i shouldnt be doing that but still. it ticks me off.

dont mean to steal your post, just had a question on the same subject

 

Maybe your buddy has his rev limiter set differently? Could just be a difference in the calibrations from one year to the next. Are the engines and rest of the PTs the same. i.e. both have AC?

 

lol if you want to rev the **** outta something buy a honda hahah had my civic for almost 3 years after the first year put a Japanese motor in it and that thing has seen 8200 shifts ever since (8800rpm rev limiter) and still pulling strong (after 180,000 kms), it will kill my truck any day of the week

 

yeah everything is the same. just his is an fx2 and mine is lariat 4x4.

and i know i shouldnt be reving the **** out of it like that but just dont understand why he can and i cant.

 

I have a superchips tuner I got when I did the lift and I set the limiter up one notch and my trans wouldn't shift right under hard acceleration. I dont know if this is just a superchips thing or just my truck but just thought I'd let you know incase you have issues

 

Why in heck would anyone want to move the rev limiter out past the factory setting! You will not get anything extra, in fact you will get a lot less since HP falls off past the peak which is before the factory set rev limiter.

Maybe it's a noise thing!

 

yeah i know theres no power gain. i proved that on my 04 when i put it on the dyno last year.

and ur right, it all about the noise. when you can get a 6k rev with pipes it just sounds badass.

 

I had my '05 Fx4 dyno tune and now have 251RWHP. The shift points @WOT is 5500 RPM
no limitor. There is no reason to shift any higher or wind it out. The factory tune is junk; and is very conserative; performance and gas mileage were horrible. Much better now.

 

You should set a rpm limit. The reason is if your tranny blows under hard acceleration it saves the engine from grenading itself from reving too high.
