Programming Issue After RaceME Install?

[Backwoodshog]

I've been reading through the forums, and nothing seems to help me out on other forums; I'm noticing it's a programming issue.

I have a 2018 2500 tradesman 6.7L Cummins and just deleted the EGR, intake valve, DPF exhaust, and S&B intake and installed the RaceME from Explosive Diesel.

I've also emailed RaceME with no response in 4 days now.

Ever since I installed the tune, the P2122 low circuit won't go away no matter what I do.

The truck is pretty much undrivable.

I have the advanced tuning levels down so I don't ruin my transmission or rear end.

Just feathering the throttle, the truck will run from 800 rpms to sometimes 3000 rpms and throw you back in the seat.

If you stay into the throttle, it's okay if you're on a drag strip and don't need to turn.

I've fully charged batteries, updated the programmer, unplugged other known sensors, and had no luck.

If I program back to stock, it goes away, but every emissions code comes back on.

I could go on, but I hope someone else has gone through this.

I've deleted my Fords and 2016 Cummins but never had this issue.

Thanks.

Welcome!

It sounds like you have bad tuning.

I agree just hoping for a little help on here or a response from RaceME.

I would agree with @watersupply189

Box tunes are a one-size-fits-all kind of scenario.

I would recommend inquiring about becoming a Plus member.

It's free and one hell of a difference.

I did pay for tuning VIN specific and all those goodies with lifetime upgrades.

Ok, awesome.

Did you have a charger hooked up to one of the batteries when loading, regardless of whether the dash gauge shows average voltage?

Once going back to stock settings, the symptoms go away partially, and it tells me you had a corrupt flash, and it only obtained pieces of info.

I had the charger on the truck for a while before turning it on and turning it on during tuning.

I've had some pretty bad *** charged batteries as I've been tuning and returning to stock the past five days, trying new fixes I've been reading on random forums

P2122 is a generic powertrain code1 that applies to OBD-II equipped vehicles.

It means that the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage1.

P2122 and P2127 both have to do with your APPS "Accelerator Pedal Position Sensor"2.

To fix the problem, you can try turning the key on, but don't start it.

Slowly and steadily push the accelerator down to the floor, then slowly and steadily back up.

Turn the key off, then start the truck3.

Alternatively, it could be a faulty FCA.

I agree it sounds like it could be tuning-related.

Did you run through the attached troubleshooting steps for the P2122 trouble code anyway to confirm?

That's a very familiar PDF I have.

It has gone through that a few times now.

The readings are the same, with the tune installed and tuned back to stock.

I've even done the app pedal reset.

I have a new pedal assembly showing up

Thursday this week to just rule that out, in case.

It randomly went out during the installation.

I've also unplugged sensors that have been known to cause this issue.

I'm stumped on this one.

I appreciate all the input.
