I have a deringer so im not knocking the product....but...its not tuning that directly communicates with the PCM...its decoy tuning that involves intercepting the MAP sensor and fuel pressure sensor via the two T harnesses you install. the power gains is done buy cutting signals in the map sensor and fuel presure sensor so that the PCM thinks theres not enough going on with MAP and fuel pressure so the PCM plus up's AFR type commands. There is no direct plus up power signals between the deringer and the PCM. if there was direct derringer to PCM command exchange you wouldnt need the MAP and fuel pressure sensor T harnesses.

I am currently dealing with a P0069 issue... have been intermittently now since 2023. I have to see when I installed my Derringer... I am going to post on this further in a different thread. Will probably resurrect my P0069 thread... love the fact the iDash has the pressure PIDs on it to monitor. More to come.
call banks and lat them know
some of the earlier derringers cause p0069
if the p0069 is on startup….they will replace the deringer
upon startup means you can clear the code and run all day if you don’t shut the motor down. And you won’t get the p0069 code as long as you don’t shut it down. Right before shut down you check and no p0069 code. Then you shut it down. Come back k to the truck and do the key on or equiv and there’s p0069 code . Which should be impossible since the p0069 code is an airflow code and there’s no air flow prestart.
there was an initial rash of p0069 codes when the Deringer first came out for the 6.7. Firmware doesn’t fix the problem. Banks will replace the Deringer especially if you report you got the code from the in set.

Sabres game is back on now but started digging into this sone more for pertinent info.
I have a Derringer tuner/Pedal Monster/ second iDash install thread. I installed these in September of 2023. Have to find my notes to get exact date and mileage but started having issues in November of 23.
I listed my friemy's Derringer tuner with iDash in August of 2020 so I'm thinking this is an earlier version of the Derringer. I bought it and closed the ad as sold... yeah I procrastinate some...
I also changed my original MAP sensor with a Motorcraft sensor and still had issues...
I'm going to update my P0069 thread but that also includes two EGR codes because my EGR cooler core was just starting to clog and threw codes, thankfully just prior to my 7 year warranty from expiring... win.

Bought the Derringer and iDash kit from a buddy of mine... he either did not get it with the kit or forgot to put it back in... but everything else was there so I believe he did not get one...
Anyways, called Banks today, talked to the Tech line and they are sending one out free of charge.
I gave him the SN number off the Derringer decal -- there are three -- and it's out of warranty. Believe my buddy originally bought it late 2019/ early 2020, so that sucks but I can run it with the bypass plug installed and the Derringer out... to see if it's my truck or the tuner.
I think it's the tuner... I'd probably buy a new one but want to get this figured out first...

at the end of the day if it is the tuner.....I might be able to make a simple circut that would behave like the bypass plug except it would take the derringer out of loop during prestart and put it back in after start.
im recalling someone did something simular but donthave details.

But now that I think about it, the first time it did it, MAY have been at start up... maybe... have to get my notes organized and get the info all down...
and it's been very intermittent but does happen. I plan on running that bypass plug and putting on some miles to see what happens -- hopefully it's not a truck issue but if it is, it'll prove it's not the tuner. This will be the test...
Banks said it's not a software issue but a Derringer issue *hardware, so without being prevvy to the design and what it would be specifically, can't really say a resistor or capacitor applied to the harness would help without having insider info. If that could be done, I'd imagine Banks would have done it to the faulty units, sent them back to the customers instead of shipping out a free new replacement unit.
But all that said, NOT saying that an external solution like that could be not found or designed....
Appreciate the input Fritz.
