Slip/ bang

[Ipkyss]

Anyone have a truck that still does the slip/bang after the last Spartan update? My truck use to do it all the time if I was not being careful. Since the update I can't get the truck to do it if I try. Just adds to the piece of mind...

There is an issue with the new 250 tune. I have seen many posts, including myself find that the CEL comes on shortly after downloading the new 250 tune to the truck. Spartan is aware of the issue. I have just been running the 210 tune, I can't stand to look at the CEL if I don't have to, and the EGR cycles fine for me on the 210

I don't think it's a tuning issue. Too many people have been able to fix the issue by adding transmission fluid for it to be a tuning issue. I think that transmission tuning (higher line pressure) may add-to/provoke the issue, but I don't believe that it is a direct cause of the issue.

The 250 tune, for some reason, went from not cycling it at all to still not cycling it and now throwing the EGR flow insufficient code.

Matt has been made aware of the issue and we will hopefully release a fix for it soon.

If you want the power of the 250 tune, but don't want to see the CEL, run the 250 EGR delete tune for a few days and then tune down to the 175 for a few hours once a week to cycle to EGR.

I firmly disagree. With any of the old tunes, 250 being the worst. No matter what I did it always happened. I tried adding fluid. The new tunes, I can't make it do it even trying. If its not the tuning, Its directly related to it. Some things just don't make any sense with these motors. Try to explain why my truck pukes with the 275, but not the 250,300,310. And I spent the better part of the day towing with the 300 today.

Others have had the issue happen with the new update.

If it is tune related, then why do some bone stock trucks do it? Hell, my girlfriend has a Honda Civic that does a rev/slam type thing with the transmission. Obviously comparing a Honda Civic to a Ford Super Duty is not the best of comparisons, but both have automatic transmissions and both experience the same issue at low speeds. Until someone can prove to me that the rev/slam issue is directly caused by tuning, I will stand my ground firmly with my opinion.

Plenty of people posted, back when the first rev/slip post came out, that their stock trucks were doing it to. Adding an extra 250 ponies just amplifies it.

First of all I made this post as a good job Spartan kind of thing. As far as the conversation goes. I guess where at a stand still. If I can do nothing but change a tune. And go from it doing the slip bang almost every time I let off. To not being able to make it do it if I try. Its a tune issue. Feel free to prove me wrong, but this is exactly what is happening on my personal truck. It's not my brothers friends second cousins buddy I'm talking about.

It's kinda like when you told me there was no way possible that the ebp issues I had where anything to do with the tuning... I was finally able to pin point it on a outside air temp. After some conversation with Matt the TUNING issue was fixed.

I was asking on this thread to see if there was a trend of the new tunes not having the issue anymore.
