PSD Engine Failure Survey
Hey all...
We've been asked many times for our opinion about miscellaneous engine failures, especially those relating to "windowed" blocks. After reading hundreds of posts on this subject, speaking to dozens of owners and manufacturers, reviewing carnage photos, and comparing countless files from damaged engines, we have a few theories. In fact, we've just finished writing a calibration simulator for the PSD that helps quickly identify just how significant a role tuning may or may not have had in relation to the failure. http://www.phptune.com/images/misc/f...ock_wot_sm.jpg In order to rule out isolated issues and identify any trends, we are conducting an independent survey of all 7.3L Power Stroke engine failures to see if there are any specific commonalities among the failures. The failures in questions will be specifically related to MODIFIED vehicles (i.e. Chips, Injectors, Turbos, HPOPs, etc.) and we would appreciate anyone who has suffered an engine failure of any type to please take a moment to fill out the survey. All NON-PERSONAL data collected will be made available for download to any individuals or companies that are interested. The survey is located at --> Survey of Power Stroke Engine Failures <-- I do want to take a moment and remind people to please be considerate and use this as an opportunity to get past the old issues and move forward in a positive fashion, NOT as a means of complaining about what damaged the engine. We've all read the posts and heard the arguments, but it really doesn't accomplish anything except getting a lot of tempers flared up. We may not all have to get along, but we are all striving for the same thing... making the Power Stroke a reliable source of performance. http://powerstrokenation.com/forums/.../icon_ford.gif We appreciate everyone taking the time to fill out the survey and hope that it will provide valuable information for all 7.3L Power Stroke Diesel owners and vendors, past, present and future. |
Bill is going to start working on a write-up regarding what caused so many engine failures over the past several years; however, you are still encouraged to fill in the survey if you have experienced this yourself! Please remember that we will not be providing your personal information to anyone else unless you give us permission. In fact, at this point, we don't foresee a reason to share it with anyone else -- period.
We are still trying to decide when and where Bill's analysis will appear. We certainly don't want to be accused of bashing anyone http://dygytalworld.ehost-services13...es/skeptic.gif when we're just supplying objective facts. As soon as we make a decision, we'll let everyone know where they can find it. http://dygytalworld.ehost-services13...s/thankyou.gif again to everyone who has taken the time to provide us with some much needed data! |
Hey that Fuel Injection simulator looks really cool. I am thinking it would intergrate well with Minotaur. esp if you are able to identify Red Flag results. It would be cool if we could run our tunes thru it and create a map of what is actually occuring.
I could sure use that in setting my high altitude SOI settings:drool2: any plans to share it with us. :2thumbs: |

Lars,
The problem with data logging with a PSD is that there is really no "true" data given in regards to injector pulse width and injection timing. Those calculations are made up in the PCM....and that's what comes out of the OBD port. This program that Corey and DJ are talking about actually figures what is actually happening based on what is commanded in the tuning itself. |
How is the progress with the survey? Any ideas when the information will be made public?
Thanks |

Cody,
Actually, the PWM PID from the PCM is reasonably accurate. Also, you CAN log SOI from the OBDII port. :whistle1::cheesy smile: Care to see??? :drool2: |
Thanks for posting the datalog, Bill.

Not a bad looking timing curve, for stock... eh? ;)

Our son, Wil, and I were diagnosed with the flu the day after we returned from SEMA. The flu turned into pneumonia, and I was in bed and out of the office for two weeks. The results are a bit delayed due to the fact that Bill had to run the office by himself for two weeks (and take care of the boys and me, too!). We're a bit swamped right now with orders, but Bill will be getting to the survey as soon as he has a minute. BTW, we'll be posting the results on here and on PSN -- we already checked with Mike to see if he'd prefer for us to keep it off PSN, but since it's objective data, he doesn't have a problem with it. :thumbs up yellow: We will probably on post Bill's analysis of the data on here since it's not worth dealing with the inevitable onslaught of posts that are going to come about as a result. :whistle1: At least on here, we can control rude posts. :) |
