Looking to tune my 6.8 v10 motorhome for lean cruise. 2015 Copperhead 2048
Bought a Hptuners interface and soon realized this is disabled/not allowed within their suite. Upon further investigation stumbled across this site which seemed most likely to have a solution.
I was hoping something like a closed loop AFR table existed- a bit naïve as I am guessing closed loop is locked to lambda 1.0 across the RPM/load range, but I really only would need lean cruise at a specific RPM if possible (1850-2300 60MPH range) where the unit spends most of its time.

Is this possible with TunerPro?
I am assuming another OBD2 interface would be required, is there a decently cheap interface to support an ECU flash? After spending $400 on HPtuners I am hoping to save a little.

Thanks

No problem

what is your ecu tag

Nope no cheap modules I know of you'll need the mongoose $450 pcmflash $125 and youll have to be a premium member$450.

Not exactly sure on the tag terminology...
I'll give you what I can see through VCM Scanner

ECM: 78E, CAN, PCM
OS: TFZP1A2.H32

Let me know if that is what your looking for....otherwise i can go find the physical ECU if need be.
I am assuming the OS is the strategy code

yep that's it
