New day new problem…yesterday we fished to re-gear my JKUR. After we reassembled all the parts we try to switch on the engine in order to test it.

First issue: the battery was down. We charge it few our an then we try again to switch on the engine.
We re-flash also the DCU with the new gear ratio
Ignition ok
We try just to go forward few meters and backward the same. No issue no dash light.
We try the 4wd L and S and no issue again.
On road test:
Automatic gearbox (WA580) limited to 3rd gear.
After few miles the engine light limp on on the dash. It start also to limp on also esp light.

Suggestions?

Did you use a programmer such as an AEV ProCal or Superchips Flashcal to program with the correct gear ratio? If not, them this is your problem.

Maybe try resetting the pcm back to stock, unhooking the battery for a while to reset everything. Then reconnect the battery and try reflashing agin. What programmer are you using?

The programmer is called Xgate2 forme a Italian producer named Xquattro

Googled Xgate2 but nothing in English. Just get a Procal. It's cheep and it works. Your problem is classic limp mode and easy to address.

Yea your jeep just went into limp mode. Just make sure your gear ratio is correctly entered and make sure your tire size is entered correctly as well.

If it's not talking to the PCM then it probably isn't programmed for your 15 JK. Look at superchips or aev. Both are cheap and work with the newer jk's

Thanks! Il try to make as you told me.

From my point of view is already important to exclude the assembly error

There is usually a first step where the programmer recognizes the PCM. Then you program for the gear ratio change. If you skipped this first step, the gear change won't be accepted.

According to you the battery down could cause similar issue?

Don't know what that error code is. I suggest you PM WJCO.

Found it. That's an incorrect gear ratio code. It's all related to the limp mode. Clear all codes and set the gear ratio. Try to get a Procal.

Sorry. I wasn't around today. Yes that's a gear ratio error code for 2nd gear. It's very unlikely you have a tranny problem just because of a re-gear, so i would make sure with your programmer, everything is recalibrated correctly.

Thanks guys! ProCal seem the solution...unfortunately also for that I have to order it and wait...[emoji31]

According to you is it possible that the programmer is not able to set the correct gear ratio until the error will be cancelled from the gearbox ecu?
