With premium gas prices getting out of hand & a thirsty 30-gallon capacity truck... I decided to load up the 87 octane tune for the first time. Filled up with regular and installed the tune. Truck started fine so I went in the house for a bit. Couple hours later I had to run to the bank. Started up and on my way... and noticed as I was putzing down the side streets the 'ol Tan Terror never shifted to 2nd. It was holding first gear. Gave 'er some gas... engine spooled up... and still no shift. No matter what, it absolutely refused to shift. Mash the gas, engine whines right up and the engine goes into fail-safe mode. Shut it off, start it up... out of fail safe & still no shifting. A little panic now... got it back home, re-installed the 87-tune and all is well. Shifts nice, took it out on the freeway and short loop around town and all is well. Very odd!

Anybody else have electronic gremilns?!

 

I had the same problem when I loaded my 87 tune except I only had 1st and 2nd gear and my speedo stopped working. I loaded the stock setting and then the 87 tune again and it corrected the problem.

Currently I am having stalling and shifting into OD under WOT issues with my programmer. Loaded the stock program over a week ago and no problems since. I have been working with Troyer Performance and am confident they will take care of me. Have you had those problems?

 

Sounds like a glitch while loading. I got the Xcalibrator and haven’t had any problems. I’ve switched tunes back and forth a few times without incident.

 

Nope, just the one shifting issue. Scary, but a quick re-load did it. It's only been a day, but I'll post if anything else should happen.

 

Could be anything - a possible glitch that caused file corruption while loading the program (which we have never had happen once in any of the many trucks we've tuned here), or you have a throttle body problem, etc.

We've had a number of reports of such types of symptoms that have nothing to do with the use of the 1714, but instead turn out to be failed throttle bodies. These newer trucks with the drive-by-dire system are seeing more throttle body failures causing problems like stalling, shifting problems, and other symptoms as well. The customer takes it into the dealer, and usually the first thing they do is reflash the PCM with some "update" - but it doesn't work. The customer drives away, only to come back anywhere from a few days to a few weeks or even months later, with the same basic symptoms - then someone finds out that it's worth a try to replace the throttle body, and the problems disappear. We've seen this happen a number of times, especially here in the last month or so.

Now keep in mind that it's not possible to accurately diagnose a vehicle sight unseen - unless you get lucky. I'm simply talking about a couple of scenarios that could potentially explain what's going on there, and we are getting more reports of throttle bodies failing on the newer trucks, for what that info may or may not be worth to you!

 

Interesting. Three times over the past 6 months, I have seen a similar issue with the Hi-Perf tune loaded. Never saw it before the superchip. In my case, it corrects itself as soon as the transmission warms up (seemingly). Each time, I started the truck (temps outside were 10 degrees or colder) and put it in gear.... Nothing. Won't shift. Put it back in park, wait a few seconds. Put it back in gear and it shifts fine. As I said, this has happened three times; but, only when the truck has been sitting outside in quite cold weather.

Throttle Body or Transmission issue ? Makes me wonder. Of course, I have no idea if it will repeat itself with the factory tune loaded so haven't taken it to the dealer yet.

 

Hi.

Are you reflashing the PCM in cold weather? You mentioned 10 degrees and I'll assume that's farenheit.

I think it was explicitly stated that you should not flash a cold PCM; there is some element of risk in doing so. Same goes for the tuner as well; it should be at room temperature.

At the minimum, if I'm considereing a reflash ( to tinker with my 9100 XTR's via ExtremeTune, for example), the truck sits in a heated garage, while the battery is getting a charge. Once I'm sure the electronics are nice and toasty and the electrical system has a full charge, I go for it. Have done this several times (and it's at least as cold up here), with no problems, or symptoms as you described.

Cheers

 

Interesting, I don't recall reading that... anywho, the tuner is kept inside and was toasty, the truck sits outside and it was in the mid-20s. I can't imagine that caused the issue. The electronics should be good down to the single digits. Then I can see some issues... maybe.

 

Hi.

This was posted by Mike last year ( used Search to find it):

" "

It's not the electronics, which will work *far* below zero (typically -40 deg C to +125 deg C; automobile component specs, for active components like integrated circuits, etc, are almost as stringent as Mil spec parts due to the vast potential temp swings experienced in the real world), it's the requirements placed upon the system by the flashing process itself.

There must be adequate voltage available to provide the energy necessary to ensure an error-free flash; this is over and above the requirements for the PCM running normally.

Also, in extremely cold weather, the handheld tuner, which may or may not be constructed with below-zero operating temps in mind, may not perform as expected; the display may not even update or work at all. LCD's are prone to temperature effects.

It's just a prudent precautionary measure to prepare for this task as indicated above, to maximize the chances of success.

cheers

 

its been around 75 degrees and i have the same problem seemigly everytime i use my superchips to switch from one program to another. it is solved when i re install the program. kind of a pain in the a.. but whatever, this has hapened numerous times. i have been checking my tsb and nothing

 

Both of my garages are heated to 60 degrees. No. I am not reflashing in cold temps. I am going to look into a throttle body replacement, upgrade, and will talk with Mike Troyer. I am going to sell the 1714 and go with the XCalibrator tune anyway within the next 30 days.

 

The tranny gremlins returned. Finally got sick of the horrid 87 tune and needed to go back to the 91+ tune. Installed it, started to head to gas station (1 mile)... no shift to second. Pulled over, re-tuned... nope! Still refused to shift. Third time just for giggles I strayed from my normal procedure of skipping the custom settings and took the time to view each setting and accept the default. Installed and all was well. WTF?! Can passing on the settings to get to the default install quicker be creating a corrupt file? I don't get it...

 

Hi dzervit, etc.,

Thanks for your post!

What we need to do are a couple of things: first, please call Superchips right away at the number in your documentation - or please feel free to call us if you prefer (for units purchased directly from us, of course), as we will be happy to take that info, along with some other things we will ask you, and get to work with the manufacturer on this.

Just a quick FYI - the 1714 in the 2004's works differently than the 1715's - anyone who is experiencing this who has cranked their shift points up manually need to set them at the "Superchips" settings, making sure to raise the rev limiter, too. We are finding that some people think "more is better," and are cranking the shift points too high - that manual adjustment capability is not a toy, it's really there only to serve as a band-aid for certain mechanical modification issues - 99.9% of these vehicles are best off using the "Superchips" shift settings. If you are having a problem and have the shift points set at the "Superchips" settings in the 1714, and have raised the rev limiter too, but are STILL have this problem - *then* that is something we need to take a look at it, and will be happy to.

Between the 2 reports we have just had in the past 7-10 days or so where we were actually able to verify that the rev limiter wasn't being automatically raised high enough, and your report and another one here in this same thread, we want to get into this with detailed info so the manufacturer can investigate, recreate & if necessary make changes to rectify what's going on.

So the first thing to do is to call us so we can go over a few things with you - our staff will collect info about your truck such as it's computer code (which you can find on a small sticker on the PCM itself, which is at the top of the firewall left of center - easy to find as it has 3 wiring harness connectors attached to the front of it and it's a rectangular-shaped aluminum box so you can't miss it - the code will be 3 letters and 1 number - like BME9, AGB1, etc., and there are hundreds of different codes), and some other info, so that we can get the info collated for Superchips so they can dig into this and see if there is in fact a real problem, and if so, get it taken care of ASAP.

When you first posted this, we were scratching our heads as we had never seen anything like that, and had never had any other such reports called in to us by any of our customers, etc. Given that, and the fact that we have seen ALMOST every strategy out there in various 2004 vehicles we've worked on, it seemed more likely that it was perhaps just a bit of data corruption in the transfer of the file perhaps, etc.

The most important thing is for those who purchased their units directly from us, to please call us right away so that we can get info collected so that this can be looked at in detail by the manufacturer - don't get me wrong, feel free to report your results & impressions here as you see fit, of course -just remember that posting things here cannot get a real problem resolved - the only way a real problem gets resolved is by calling the manufacturer, or if you prefer, on units purchased directly from us, by all means please feel free to call us so we can work with you on this to get it resolved, OK?

Just to let you know - this is something that has NEVER happened in our Troyer Performance *custom* tuning, as each program is literally a scratch custom tune, done one by one (which is also why it takes a little time to get them ) - but when we're talking about a device like the 1714 MAX-series Micro Tuner, which contains literally over a thousand different programs (3 for each different box code), while each program is made for each individual computer code, it is possible (though rare in the extreme) to once in a while have a scenario like this where they find a very rare strategy that just doesn't respond "like it should" - or it may simply be that on one certain production run, there was a file that got corrupted as part of that process in manufacturing, etc. Rare in the extreme of course, but once in a while, things happen with all manufacturers that need to be resolved.

So let's communicate on this dzervit, and get the info we need so this can be looked at in specific detail to get this resolved for you (and anyone else). Superchips is MORE than happy to do that, the last thing they want is for you to have a problem - so don't worry, we'll make sure that any actual problem with the 1714 gets taken care of for you. The first step is to call either Superchips directly, or for any units purchased directly from us here at Troyer Performance, please feel free to just call us at our number listed below with your truck's computer code - (and that goes for anyone else seeing the same symptom who purchased their unit directly from us here at Troyer Performance).

Thanks again for your post, & talk to you soon!

 

Thanks Mike, I'll get that PCM code and give you a jingle this week (as I did purchase from you, who else?!)

 

You're more than welcome & talk to you soon!
