pics?

is it turbocharged? not sure if there is room in yours but the 2nd best mod i mod to mine was the v3 air box mod with a boost activated exhaust cutout. (documented on cumminsforum). cleans up the exhaust and noticeably changes the way the motor runs once open. bottom end torque retained.

22-25 is a huge gap, which is it? or is that 22-22.5? (which makes sense). every tank on the ram & now dak is looked at and recorded on the receipt.

 

Because V8Cowboy is staying up to see results lol... Here are before pics, datalogger not working on the phone for some reason. Note the 225 miles @ just under 1/2 tank on the gauge... this is consistent with 16ish mpg's.

 

Sure, it's turbocharged - that's what the "T" stands for in 4BT.
Actually I have tracked 50 or 60 tanks using the Fuelly app and I did mean 22-25 mpg. Hot? Cold? Towing? City? Mountains? Lots of variables lead to variations in fuel economy. So yeah, range has been from 22-25mpg.

 

update... on startup, zero change old vs new in data at idle. filled it up, 15.3 mpg after fuel wrap tank. initial drive a lot of downshifting indicating low end tq loss. took it on a 60ish mi drive and yeah definitely more power.

observations towards the end of drive: less downshifting +1-1.5* of timing, o2 sensor is barely more active. i expect the adaptive learn tank to suck, definitely on it more so far. it is noticeably better in power.

how long does the adaptation take?

 

Another update... added more miles on it tonight after a semi cool down to 130*f CTs... 110 mi total, nearly zero downshifting on the same hiway, shorter distance with more "city" driving. Fuel gauge is just past the 1/8 mark off full. That is a noticeable difference. Past tanks would get me ~110-115 miles at the 3/4 mark on the gauge. This will definitely be an improvement and probably a best tank yet for me on this truck. Would like to get the odo up to 200 miles or so and then refill as I'd like to go and get the rest of the sensors installed before work next week. Not 100% set on it but it is my preference. Time permitting of course, I heard the crank sensor is a fun one.

 

Mine (map) arrived yesterday. Will be putting it in later. We'll see if it makes a difference.

TPS is about 7 years old.
O2 sensors are a year old.
IAC valve is 2 years old.
Plugs have around 14K on them
Crank sensor is original

All sensors are Mopar... this MAP is Delphi.

Edit:
So I can tell right away this won't be fun. First, it looks like someone may have messed with or changed the sensor at one point., One of the bolts is missing and God knows what that thing is they substituted with it.

 

[QUOTE=Dodgevity; One of the bolts is missing and God knows what that thing is they substituted with it.[/QUOTE]

I've read this is how they original are mounted, just one bolt and a stud, it will stay seated because of the O-ring and just have to stay in place with the pressure of the "one" bolt, should be okay.

 

Yes i am , thanks for all the info shared Steve

Looking to set up my Torque app the same, so i can evaluate the comparison/differences.
When i start mine i will not have all the data present, when i start driving they come all active right away, don't know why, might have to wait a little longer for data has been processed.

 

Looks we like the same Torque interface and digital

I'll have to add Boost and Timing on mine.

So things looking good on the Map sensor ? Now i need to order one and see for my self

 

206.1 mi, 17.037 mpg...

crank sensor is failing when engine temp is above 203* or so... new sensors go in this weekend. going to clean the throttle body while i am at it
