? about my tune from henson

[2000XPLORERSPORT]

should i keep the axle ratio on stock, or 3.73 which thats the gear i have. i know the fan temps don't matter since i have no electric fan. tire revs/mile is on stock value. the spark is 0-2000, 2000-4000, 4000-8000. if i raide the spark, will i get more power? and the wot air/fuel. if i make it richer, will that give me more power? i raised the spark and made it richer before quite a few times just to test. didn't really notice a difference. any suggestions? thanks.

are you running a 93 octane tune?
if not, the gains are hardly noticeable.

and I wouldn't mess with spark or AF with out putting it on a dyno, since changing spark affects your AF just as much as changing your AF does.

These are all questions you really should ask Jim as he's the one in the know with your tune file.

He may have left some "headroom" to add timing, he may have not.
you dont want to risk hurting your motor until you find out more info.

hope this helps

yes im running 93 octane from shell. actually, james sent me 3 tunes when i bought the programmer. i then did some data logging and had another sct dealer named adam from new york fine tune me 3 different tunes. not saying the tunes from james were no good. i could for sure notice a difference from his tunes. i just thought making some passes and data logging it would really help tunning. i made probably 10 passes and e-mailed all the data to adam. he then tuned everything and e-mailed me tunes. all this for free i might add! i talked with him on the phone for weeks. he really spent a lot of time making my tunes. i just was curious if i can change anything to get a little more.

 

[2000XPLORERSPORT]

i know after adam did my tunes, then i made a few data logging passes and e-mailed them to him, my 0-60 time really improved. on the explorer spec page it shows a 4.0l ohv 2000 explorer running a 0-60 time in 10.5 seconds. and the 5.0l in 8.8 sec. adam said i was about in the 8.5 sec. range. faster than the 5.0l but i don't think quite as fast as the sohc which says 8.1 sec.

Likely Jim gave you a safe conservative tune, which is good.
Adam probably gave you a tune that is closer to the "jagged edge".
I would NOT add any timing to adams tune, without talking to him again.

I'm not a big fan of "jagged edge" tunes, I'd much rather have a safe and conservative tune.

Without Dynoing the truck, you dont know if your in a "safe spot or not".
I'm fairly certian that Jim doesnt send out jagged edge tunes.

When comparing tunes, there should be alot more to consider than just 0-60 times.

What is the current WOT AF of your truck?
If you cant answer that, they you shouldn't CHANGE ANYTHING other than transmission shift points.

Do you have WB02 on the truck?
IF the answer is no, then you should not change anything other than transmission shift points..

I know it's very tempting to go in and "mess with stuff", but be forwarned, that "messing with stuff, many times makes a MESS OUT OF STUFF".

yea i agree. i would love to get it dynoed! but don't know of any places close enough. im not sure what the wot a/f is. i just do the passes and sent adam the info. yea, i got my trans shift points up at 25%.the highest it will let me go. and i love that! it really throws you back in the seat. what exactly is wb02? see i did a few things since his last tune a couple years ago.like i changed my plugs from bosh plat.irridium fusion plugs to motorcraft plat plugs. i would like to make a couple new passes and datalog it. but i haven't talked to him in a couple years. i could contact james and see if he would take a look at my data logging and go from there.

Your gear ratio questions that I overlooked...

Dont worry about the rear axle setting for now
Revs per Mile is what you want to adjust..
You need to go to your tire manufactuers website, find your tire, then find the REVS PER MILE value...usually it's listed on the tire manufactuers website, if it isn't then you need to call the manufacturer.

you need the RevsPerMile for your tires...two different tire manufactuers will have different revs per mile for the same sized tires.
Just because they both are 2blahlbha/blahblah/blah blah doest mean they have the same "revs per mile"

WB02= Wide Band 02 Sensor it's a tuning device.

If you get WB02 and the SCT software, then you dont have to send datalogs to a third party.. you could tune it yourself.

 

[XLRVIII]

im not sure what the wot a/f is. i just do the passes and sent adam the info

Without WB02, then adam is "guessing" at AF ratio
That is bad.

The tune James sent you likely has alot of headroom for vehicle variances.

I wouldn't attempt to extract all the available power via a remote tuning scenario, guesswork..can lead to very bad things happening.

ok, well i could just leave the tire/revs on stock right? i might go to michelin's website and check that out though. ok, i heard of a wb02. nope, i wish i had one.

im not sure if i still have the tunes from james. i got 3 from adam in the programmer. i think i burned the 3 tunes from james on a disc. i mean im not complaing about the tunes or my explorer. it performs quite well for a mostly stock 4000 pound+ truck thats only rated at 160 hp stock. i just want to try and get the most out of it. i think i will just leave every thing where its at. at least until i do some data logging and have either james or an sct dealer look at it. i really appreciate all the info and help you gave me!

 

[XLRVIII]

is your speedometer correct?
If so.. leave axle AND revs per mile alone.

you should start learning what your seeing in your datalogs, it'll go along way in helping you understand the process.

www.calibratedsuccess.com
Greg Banish has a great book, its a small book, not too many pages..but it's a GOOD READ and goes along way in "opening the eyes" to the tuning process.

To date it was the best 24.95 I spent on my ride.

yes my speedo is correct. yea, i'll leave them 2 things alone. well i did see all the data in my passes i ran. i didn't understand every thing. ok, i'll check out that book. so you got a tune from james to i take it?

 

[XLRVIII]

so you got a tune from james to i take it?

I tune my own stuff, with the same software he uses.

I am not familiar with Jims tunes at all, I'm just very familiar with the software and the tuning process.

oh ok i see. thats cool. so if i was to make a few passes and data log it, you could take a look and maybe help me fine tune any thing if needed?

 

[XLRVIII]

you could take a look and maybe help me fine tune any thing if needed?

you would need to buy the software from SCT.
I cant tune your vehicle..or fine tune your tune file.

what software? i got the disc that came with my programmer. live link and live load. i found my tunes that james sent me. i got them burned on cd.

 

[2000XPLORERSPORT]

the tunes are ll3 files. theres stutler performance, stutler street and stutler tow. stutler is my last name. them are from james. i also have the 3 tunes thats currently on my programmer from adam on cd which are also ll3 files. there labeled low timing 94.

 

[techieman33]

to adjust the tune yourself you would have to buy sct's pro racer package ($350) but unless you know what your doing you will be much better off having James make the adjustments there are things that you can adjust that could easily do some serious damage to your motor and transmission.

yea, thats a little out of my price range. especially just to make some minor adjustments. i already spent $400 for the programmer. but i would be willing to have some one look at my current tunes. i have 6 all together. but out of the 3 in my tuner, i just use the latest tune adam made me.

 

[2000XPLORERSPORT]

of course i need a little reminder on how to go about setting up everything for data logging. its been almost 3 years since i did them. i know theres parameters you select that you want to record when making a pass. i think you can select 16 parameters. then you put them in the programmer vis usb port. then plug the programmer into the truck and select what im doing and make a pass.
