Bad idle after tune installation

[Myshelby3425]

That is really strange guys. Your both N gauge Lund tuned...? Can you take vid of this bad idle? Be curious to see what this exactly looks like.

When coming to a stop around town, the idle jumps up and down within 500-600rpm

Yea th revised e85 tune. On full e85. What’s tests are they having u do? Mine may be March as well but not 100%, have to look.

Looks like the same tests when I first got the tune:
Idle for 3-5 min, full WOT, hold and 1500, 2500, 3500RPM, etc

Ok, for clarification are we talking a 100 rpm variance bouncing or 500-600 rpm jump? Like 600-1200 back to 600 rpms?

That is crazy. I did not have to anything but wot e85 logs with Torrie. 4 revisions and good. May build.

Mine would jump from 700 to 850-ish. Would be super noticeable at idle, but once you gave it gas or waited like 3-5 seconds it would go away.

Their logs are more involved but they still seem to use a basic canned E85 tune for all 2018 GT's. I never got one revision throughout all my logs I sent out. So either they insist their tune is good or they are overlooking something with the 2018 A10's

Varies it could be 100-200 and the worst I’ve gotten is 500-600. Like 500-1000-500 throw in neutral, rev a little then it settles back to 770ish.

I bet your right on canned file to start with and as long as you don’t complain they call it good. Saves them time and $.

Torrie said he had to build the E85 file/tune after finishing the 93P. I had easy 10-11 revisions total between 2 tunes. He kept finding limiters rpm/speed in both ecu and tcu code. I’m sure Ford has done rolling tuning updates since 9/17.

Yeah that is jacked up. My e85 tunes idles and drives like the 93P and stock. Only difference is when you put your foot into it the torque & hp obviously greater.

Where is your Tuner Torrie from? I’m just about ready to change tuners and ask for a credit from Lund.

Yeah Im about to do the same if I get another "there's nothing we can do" line

I'll take the guy's info too just in case. Does he have any dyno numbers from tunes he's done on 2018 GT's?

No. Different outfit, but hear they are good.
