predator caused code

I just got my predator But after installing the 91 tune, I started it up and its................ missing like crazy! threw a bunch of codes,so i cleared them, tried & again. better, but still misses. shows a P1411-@ndary air injection incorrect downstream flow. WTF??

It was running totally fine B4. When i cleared the codes it said tcm failed to clear. Any ideas?

Re: predator caused code

are you running 91 octane fuel? I've read throughout this forum that if you use the 91 tune you have to burn 91 fuel.

Sometimes it takes a lil while for it to adjust. Try n load it again, and just let her sit for a lil while. If it's ok go for a lil ride.

Re: predator caused code

Make sure you have everything turned off in your Jeep and make sure the doors are closed for the whole install.

Did you have any luck?

I had a similar issue the first time I loaded the tune in my 2005 - I was only running on 4 cyl, the tune did something to the MDS. The DS forums recommended I disconnect my battery to complete the tune process (which I also had to do to get my cruise control working again).

I've since downloaded the newest DCX file and calibration file to the predator and haven't had that issue with the new calid. Also, remember to return to stock every time you do an update.

Seems like the 2005's react strangely with the DS, but mine is all sorted out now.

Re: predator caused code

Yep, it's ok now
It wouldn't let me do ANYTHING till we updated it online.
I haven't tried the cruise yet, but ill check after work.
Thanks for the help
