Compare the logs of the two that should show something

This is actually smart I didn’t think to do this. I also don’t fully know what I’m looking at because there’s a lot going on in the datalogs. I’m new to this.

I’m trying but as you can imagine they are not giving in easily.

Just do a credit card dispute. Product not as advertised or whatever. Let the CC company do the work if you can show you’ve tried to fix the issue with Lund. You don’t even have to work with Lund anymore if you’ve tried to solve the problem.

Dispute it and move on. It’s no longer your problem.

I just opened a dispute today. The hard part is showing them 60 emails back and forth between me and the tuner. Appreciate the info!

Just focus on the messages that are important. The ones showing you tried to work with them to fix it.

Also, I’m still open to looking at data logs of the issue if you have any to send.

Try to de-select some of the PIDs on the data logs so its not so messy and overwhelming. Find what you can that's fuel, spark, and air related and compare them one by one. Obviously the graphs won't be identical. But maybe a large anomaly will stick out.

Couple random thoughts. Was there any large difference in E85 ethonal % when you had the PBD tune vs when you loaded the Lund tune? (I once transitioned tunes... just as gas stations transitioned from summer E85 to winter E85, the E% plummeted 30% over night...my cars idle was crap)

I know you want the 91 tune since 93 is rare in your area. In the meantime, you could just flash back to the PBD tune and buy a bottle of Boostane and add a few Oz's every fill up till you figure it out?

im sure it's been suggested to hit up @Wengerd. They do fantastic work and even better customer service than anyone. And for those of us (me)who need things explained to us like 5 yearolds when it comes to tunes....customer service is a premium I'm willing to pay for

I hate tracking down Idle issues. Its either super simple. Or something super simple hidden behind something complex. Fking headache

Agreed. If my idle issue turns out to just be the O2 sensors, I will feel a mixture of somewhere between celebratory and being really pissed off as I have been throwing money at this every now and then for 3 years

Lund offered a $250 refund out of $725 because they still don’t believe the issue is their tune. E85 tested 87% ethanol and it was the exact same tank sitting there Pbd would idle just fine and lunds tune would idle between 435-905 rpm’s at operating temp for about 3 minutes before the vehicle eventuality would just kill itself from surging. Pbd tune I can sit an idle for an hour and it holds strong at 900-1000(higher if I have AC on). I can get by with the e85 tune I have for now because e85 is at every gas station here just worried about if I were to take the car out of state how available e85 may be. I did get ahold of wengerd so I will see what they can find.

After reading this, I’m a bit concerned about your idle speeds. 900-1000rpm is high if the car is warmed up. I have seen instances where the idle speeds were raised to mask an issue with the car or to tune around something that’s much more difficult to fix than just raising the idle speed a bit.

Lund could be right that there is an issue with the car…

I’m not fully sure the exact idle range that just sounds about right. What kind of issues could be covered up? Other than the common ones I’ve found is there something deeper im overlooking?
