[2005 wrangler X ?]

So I had emailed Mark and he replied the same day telling me to call him
I called him on Monday we talked, Hes a NICE guy then he switched me over to his secretary ALSO a very nice Lady
and she took my info and card
,
Thursday delivered to my home in Maine thats with normal (cheapest) shipping
,
20 deg outside, got the proPain turbo heater going in the garage and warmed it up to 50deg so my fingers could function and then shut it down
I DID exactly as Marks instructions told me to do
took me 20 minutes old one OUT Marks IN
Opened the Garage door
this is a COLD start
went through the Gauge test --all good
went through the key/code test --all good
started jeep up
1-My idle was Much smoother than before
2-I was amazed as I watched the Tach as it reduced the RPM on the Motor--Id never seen THAT before on my jeep
3-seems like it comes up to running temp FASTER than before
4-at running temp ive no more (slight loping idle) I had before
5-drove to the store and back 18miles NO more hard shift 1st to 2cd
feels like a whole new engine got put into my Jeep
Ill be sending it back for the add on shift point tune when i get the funds after xmass

THANK YOU MARK

@Wranglerfix is the man!

 

[D's Jeep Wrld]

He is the man ! Great Pcm,Its been on my LJ for a bit over 20k miles now and zero issues and many writes on it from tuning and again zero issues
And yes you can tune that same PCM using HpTuners For liability issues and mainly EPA issues I bet! he has to say that you cant tune em but you can

Got a WranglerFix PCM in my 2005 manual and it's running great. Another vote for highly recommended.

Yep, it’s not on him if you create problems by tinkering…can confirm his PCM took the CARB legal Banks tune.

I put the wrangler fix in more than a year ago and have had no issues at all with my 2006 TJ. I had the hard auto transmission shift problem. Mark sent me my new unit quickly, all I had to do was give him my Vin number. Wrangler Fix is an outstanding product and value.

So, I have a moderately built TJ, largely because here in Australia we have some over the top regulation when it comes to vehicle modification.
Anyway, a second TJ came up for sale in my favourite colour, and this thing is virtually standard. A 2005 auto with only 76000 km on it (47000 miles). One of the few mods I wanted to do to it was put a Wranglerfix ECU in it with the updated performance/shift points.
This TJ was already as smooth and nice to drive as a TJ can be. The Wranglerfix PCM though made a really nice stock Jeep so much nicer. It’s just in the right gear when it should be now. I don’t know how else to explain it, but wanted to say, if you own an 05-06 auto and you are waiting to have a PCM fail before you get one of these. Stop waiting and order one now. It is a huge improvement to the drive ability.
Thank you Mark, very happy customer this side of the pond
