Has anyone completed thier datalogging to the new docs without A/F ratios and just used the XCal 2 and a laptop? With Xmas coming and the cost of a Dyno here is San Diego, the cheapest $260 / hour, I was thinking I would try this to save some money. My truck is running great on the tunes as they are now, but it would be nice to verify this with Troyer, before my 60 days are up, and have Mike tweak them if needed. I know this will not get the tunes right on but from what I've read Mike can get them pretty darn close. So has anyone tried this or have any thoughts?

 

Here is some food for thought..............5400 RPM in 3rd = 135 MPH. It appears since the A/F data from my Dyno will not be used as Mike feels that it is way off. The Xcal data seems to sugest that my truck runs rich not lean as the wideband data says. So judging from that the Xcal does collect reliable data. I would just be concerned where you can run at the those speeds without endangering yourself or others

 

If your not doing your datalogging on a dyno you can use 2nd gear which keeps the speeds down.

 

The new documents ask that 2 pulls in 3rd be done and 1 pull in 2nd. i would talk to Mike first if this were to be altered. just my $.02

 

If you’re not using a dyno you do the load data-logging in 2nd gear ~ page 4 - new docs

 

Wow!! I had no idea our trucks were capable of such speeds. Wonder what they would do if you dropped them off into 4th.

P.S. Thanks 05silverFX4 for your extra help. If you can draw circles and arrows pointing me to the right area of the SCT website you definitly have more computer skills than I have. I am still trying to get it all figured out.
Thanks again,
Bruce

 

This is what I read also. I think I'm going to give this a shot over the Thanksgiving weekend and e-mail the info to Mike. I mean it wont cost anything and it cant hurt and it might just make my tunes all that much better. I will let you know after I complete the process.

 

Hey good eyes, I did not see that. Though it does make more sense, 135 would be pretty dangerous on public streets. Thanks for correcting me.

 

Second gear at WOT is still going to be approximately 85mph or so time you hit the rev-limiter

 

Hi everyone,

Any dyno that charges more than $150 an hour for a true eddy-current load-bearing dyno, or more than $100 a hour for a standard inertia dyno is either getting away with highway robbery, or you are trying to get them to do far more than a few simple pulls with A/F's - or for some other reason, they just don't want you to bring your vehicle in.

Something doesn't sound right, it should be very easy to locate a dyno within 50-100 miles of n the San Diego area that doesn't charge anything like $260 per hour - that is the heart of silicon valley, and I have spent quite a bit of time there. All it takes is doing proper homework, like calling Dynojet directly to get a list of several of their closest facilities - they are NOT all listed on Dynojet's web site, not by a long shot - in most cases, you have a choice of several good dynos within less than a 100 mile radius, who will charge FAR less than any $260 per hour for a few simple pulls with A/F's.

And yes, doing 2nd gear pulls is acceptable on these trucks when datalogging on public roads - we don't want you running 120-140 mph in 3rd gear at redline!! In fact, in many 2004 & up F-150's we do 2nd gear pulls on the dyno ourselves, because they generally do not have good enough balance on the driveshaft for much more than 115 mph or so, and the tires aren't the best for 140 mph blasts - which is a common speed to hit on a dyno at redline in 3rd gear in a late-model F-150, especially 2004 & up!

I hope that brief info helps, & good luck!

 

Thanks Mike, I guess I'll try to call Dynojet, but the four places I tried, I got from there web site. 3 of them were $300 min and the last, The Dynoshop, in Santee CA was the cheapest at $260 / hour or $98 for two pulls and $49 for each additional pull. They figured it would take a min of 7 - 8 pulls to get all the data. I guess its true what they keep telling me, "It cost to live in San Diego" but it has been in the 80's for the last week

 

Why will it take 7 to 8 pulls to get the data? 3 pulls, 1 in second, 2 in third is all you need

 

If read mikes directions corectly the min would be 5 pulls 3 in the most aggresive tune and 1 in each of the other tunes but preferably 3 in each tune for a total of 9. So The Dynoshop told me they would need 2 pulls to get it dialed in and then minimum 5 pulls Mike needs for a total of 7. I guess since this is new to me they could be ripping me off, I dont know

 

Take the 90 minute drive up to Colton. It's 80 degrees as well, and it only costs $125 per hour!Drive North For Good Prices and Awesome Weather!

 

On page 3 of the NEW datalogging sheets ** number 2.) says 3 dyno pulls
