Anyone know what the normal PCM parameters are for 2004 Wrangler 4.0 42RLE?

Here are some vids, sorry about the bouncy. Please let me know if you cant view them. Def want to use a pc, clarity is crap on mobile device.

Fuel trims are in the negative most of the time, assuming that means it running rich. Going to install all new NTK O2 sensors and a new mid-pipe with all new cats, hopefully that will sort out the fuel issue.

Wish me luck!

Anyone had a chance to look at the videos? Just curious as to some insight on what the numbers mean to someone with experience.
Thx

Ok, swapped the mid-pipe and O2 sensors, it's definitely breathing a lot better. Stft and ltft are still in the negs. I want to try stock injectors, vs the 26# I have. Any recommendations for good stock flow injectors, other than OEM?

Thx

I bought my bigger injectors from fiveohmotorsports.com or something like that. They sell stock sized ones as well. No input on quality other than they work.

Ok, thx for the input. Drove to work this morning, and all stft and ltft numbers are in the -'s sometimes up to 20%. Crazy..

Hey All,

Just a quick update, I've ordered a tune from FRP Performance; waiting or parts to arrive.
I want to keep the wide band installed, anyone know where I can get an A pillar dual gauge pod? Google isn't giving me any love...

Keep you updated on how it goes.

I took a look at the spark plugs, they look like they're burning pretty clean. I still think it's running rich, however, not as much as I thought and there's definitely timing curve issues at play. Not going to switch out injectors until I get a reading from FRP Performance, don't think I need them.

There is an A-pillar pod out there for '03+, but I don't recall where I saw it. Quadratec maybe? There is a cluster they make for all years that sits on top of the dash.

I checked all the mainstream companies, and even some of the side stream ones, no luck with Pillar pods

Will look at the universal dash ones.

Thx for the input.

The dash one isn't universal. It replaces the factory useless coin tray that sits top/middle of the dash.

I saw those, not very fond of the looks. Will keep searching.
Seems much of the TJ stuff is getting harder and harder to come by

Hey All,
Just a quick update. I received my second tune, what a difference it makes!

I'm now drivable

Need to put a bit more miles on it then do some data logging and send back to Ryan.

Will post an update.
