HI!... Good A/F's are critical to making good power and torque. Last year I went to the dyno with a basic tune from MIKE T. I believe he got it as close as possible since he was just basically guessing since I gave hime no data logging at ALL! We ran the truck and I made 298RWH.P and 330RWTQ. Everything looked good except the A/F's were way off. At WOT I was at 14.7 A/F's!!!!!!! Called MIKE T up and he adjust the A/F's, that's it, nothing else. Went back on the dyno and laid down 354RWH.P and 392RWTQ with a 12.89 A/F at WOT. This is on a built naturally asperated 5.4L 2, VALVE with 8.42:1 compression and turbo grind cams.

 

Yeah I have high hope for the adjustments for my A/F ratio.

My results are still good as they are, but the A/F ratio needs work. I know Mike can take care of it, as it could be any number of reasons this is happening. My truck could have been lean or rich in stock trim and the tuning just compounded the issue. That's why Mike has us dyno.

By the way, thanks for the help Neal over the phone while I was on the dyno!

Thanks again,

Duke

 

HI!... Just so you know, wrong NEAL. I am not affiliated with TROYER PERFORMANCE at all. Just a good friend of MIKE T's for over 7 years now. I believe the "NEIL" that works for MIKEY is the one you want to thank.

 

Oh, lol! I thought you were both the same Neal....my mistake. I always wondered why you went from living in Canada to living near TP.

Duke

 

LMAO


Either that, or having a commute that makes Marc's look like a local trip! In a Ranger!

A/F's - mine were between 14.68 (idle), 11.84 (3900 rpm, 89% load), and 12.4 ( 5784 rpm, 66% load) as measured using an Innovate LM-1 & exhaust clamp with a freshly calibrated wideband sensor, interfaced to the Xcal2.

I too think they messed up your A/F measurements - too much power for those readings to be accurate, IMHO.

Cheers

I see the chart's but...you got some high numbers based on your mod's and it running so pig rich

 

I haven't seen anyone else show numbers with the 3.25" AF1 instead of the 3" AF1. My numbers are actually inline with the individual who has the 3.5" AF1.

I'm doubting the measurements are off. It's really hard to say the measurements are off by just looking at the graph. I'd say it's more of a call when you're there. I'd be more inclined to agree with you guys, but this shop has some really knowledgeable people who did a good job.

EDIT: Email just send to sales@troyerperformance.com @ 10:13am. This email included my ".drf" files from the dyno pulls and my ".csv" files from data logging. I spoke with Crystal and she was extremely helpful, professional, and kind.

[I'm just storing my information here for now as it is easier for me to track. I have a lot going on with work and just don't want to forget about the truck tunes.]

 

Neal

Did you get your truck dyno'ed from Mike? or someone around town?

Duke

Did you make up a datalogg using the Xcal2 for Mike or are you using the data from the dyno? or both?

 

Both, you have to data log and do a dyno. The big part of the dyno is seeing the A/F ratios. However, I'm pretty sure Mike makes use of the other dyno information.

The big thing is data logging with the Xcal2 and your laptop. You'll have to data log during each of the three ENTIRE dyno runs and a "no-load" data log that you can do afterwards in the parking lot.

I'll be honest, it scares you at first if you don't have experience with it. However, practice a couple days in advance with the data logging and make sure your files are setup. By the time you get to the dyno you'll know exactly what you need to do.

Mike's directions are really good. It's just a lot of information at once (but it's necessary to get the job done).

Just for fun I ran the following numbers after finding several posts that show the 04+ 4x4s put down rough 205-210 HP at the rear wheels STOCK. Which is a 30% loss.

Spec being referred to / Stock / AF1, XCal2, Maggie Exhaust / Gained
flywheel HP / 300 / 368 / 68
rear wheel HP / 210 / 257 / 47


flywheel TRQ / 365 / 470 / 105
rear wheel TRQ / 256 / 329 / 73

Actually, ALL vehicles that are computer controlled are going to read about 15:1 at the start, and then richen up, and that is extremely basic....

First, the truck is running in closed loop - which means it will read upwards of 15:1 JUST AS IT SHOULD until it goes open loop - which happens when the operator floors the throttle - so no, at NO TIME is Duke's truck running lean.

Also, the power numbers look pretty high for it to actually be running that rich, but we most certainly will take a look at his data once we have the others in front of him done, and if it calls for adjustment, then of course we will indeed make that adjustment for him!

I also have a comment for "RogerF" - just some quick general info for you until we get a chance to talk, basically, OK? First, you cannot do dynos in different years and expect to be able to compare them, it just doesn't work like that regardless of any correction factors. Also, you only sent us a dyno graph, no other data whatsoever - that does not allow us to make any adjustments, my friend. I'm guessing you did not spend any time reading our extremely thorough and painstakingly written datalogging instructions we sent you, and you will need to datalog that vehicle properly before we will be able to do any adjustments. You need to provide ALL of the data that we describe in our datalogging instructions or we cannot make any adjustments. So the first thing you need to do is to go back and READ our datalogging instructions that came to you in the same email file attachment that contained the custom program worksheets. No bonafide tuner makes adjustments based on a dyno plot alone, as that prevents you from being able to properly scale the MAF transfer function to make any needed corrections in the A/F's - well, unless you want to just make some wild guess, and we do not do that. So my first suggestion is to go back and read your datalogging instructions and provide us with complete data, not just a dyno plot - that is required before we can do any adjustments.

Last - as every single person who has ever attended one of our dyno days knows all too well, NOBODY has ever gotten only a 13 or 17 Hp gain from our tuning and the AF1 - heck, our 87 octane tuning alone on a 5.4 3V gains far more than that! Nor do these trucks ever put down any 237 HP in stock trim on an *accurate* dyno using SAE correction factors, either - that's a real tell-tale here. We have dyno'd more F-150's than anyone else in the world (well, except possibly Ford themselves), and not once has any 2004 or newer 5.4 3V ever come even close to 237 RWHP - the very highest ever was 219, just to give you an idea of what to expect on a properly calibrated Dynojet 224Lxc like we use.

We are going to be leaving shortly for Thanksgiving, as I have to go see my daughter, so we will have a short week here, but I hope to speak with you about this in more detail when we get back next week, Roger - thanks!

 

Hello Mike,

Yeah I read through previous information and like you said, the truck is never actually running lean. I look forward to discussing my information with you and taking the steps to correct my tunes.

All,

I just got a call from Neil at TP (different guy then the Neal on here as I learned the other day ). He was very nice, professional, and knowledgeable. I was suprised to even have a call today as I sent the information in this morning.

We discussed my data log information and dyno results. We're checking on a few things and once Mike has the opportunity to look at my information we *probably* have to do *some* rounds of changes to my tuning.

I'm not crazy about paying multiple times for a dyno but that's the price you pay to have the confidence that things are done right. It's just the way it goes.

Overall it's been a great learning experience so far and I've learned a lot of things I didn't know. I look forward to sharing the rest of the process with everyone here.

Thank you,

Duke

 

man i hate when i read things backwards. i think i need glasses.

 

Hello All,

Well when something doesn't seem right, it usually isn't.

Neil had an idea that I might not have recieved the 3.25" AF1 pipe and rather had the 3.00" AF1 pipe. Well after he asked me to, I double checked and low and behold I have a 3.00" AF1 pipe.

I'm sending Neil the pictures now in an email and then will discuss this with Neil tomorrow.

Quite unfortunate, though history has shown that TP has excellent customer service and fixes *things* that goe wrong.

HI!... I got my trucked dynoed by JOEL at WP RACING here in WINDSOR. They are now located at ROTAN (DO IT YOURSELF GARAGE) on KEWS DR. by Lauzon Parkway here in town. Joel did all the data logging for my truck.
