Ask @AndyG how he likes it.

Strong idle. Crisp. Improved shift points. Better acceleration.

You’ll have a gleam in your eye women will notice. Be careful.

It's known to cause cancer in the state of California.

“It’s known by the state of California to cause cancer.”

I’ve yet to figure out “who” the state of California is.

Tempting, but I might wait and see what other report back on results before returning my good WranglerFix PCM for a tune. Cool that this is being offered.

Honest 3 month assessment: it doesn’t change the shift points. It does have better throttle response. If you stay on the pedal it will keep the rpm’s higher. If you let off it will drop rpm’s and lug. That’s the one part that annoys me. I tried hitting the O/D button. Better. But that’s kinda like back to square one.

The “lovely” state of California. The one state that somehow knows what no other state knows.

I am going to use that in my repertoire!

I believe this is the cancer you speak of.

so... for the $275 for the tune (at least the last time I asked), would you consider a good purchase? or do you think you just could have saved those $275 and drive your jeep pretty much the same?

I got mine in 2022. I Emailed the invoice and information over to @Wranglerfix and asked if they think what i received would benefit or not from the software change. For $275 I'll take anything to make the auto run better.

I’d do it again.

Weird things happen in CA. It’s kinda like Atlantis, except its location is known.

I’d do it again.

Definitely worth doing.

Do you have to send the PCM back to Wrangler fix for this upgrade?

Yes

 

[Lemmy]

Mark, is there any word on the ‘03-‘04 performance upgrade and possibly TCM changes as well?
