Few questions

[Indy'sexclusiveZx3]

Mods if not in the right spot please move, is there anything else that can cause the car to go into limp mode other then it getting ready to over heat, And what is p1127 and it's causes? And finally question with a datalog is there a way to find out if you PCM is shot?

Exh temps out of range , o2 not complete , you could have a stopped up CAT , just guessing

If you can datalog, you should also be able to look up the P1127 (in LiveLink, Ctrl+T).

Odds are it's a wiring issue with the O2 heater (rear O2).

Your ECU is just fine.
It's a tune issue more than it'd be a bad ECU.

= p1127

^I know what it is. Looked it up in my Ford software.
I was trying to show him how to find in with his software.

I don't have a cat, and I still need to finish my tune with Tom just be so damn busy

[Indy'sexclusiveZx3]

Ok more questions on top of the ones already, sometimes with in 2 mins of starting the car is will go into limp mode thoughts on fix? And Tom can you tune out the limp mode safety feature?????

[1turbofocus]

No that wouldnt be wise to do , but if you had a xcal we could narrow down your problem and fix it vs covering it up

Tom

[Indy'sexclusiveZx3]

Your right about not covering the problem up, but I just can't comprehend how it could go into limp mode after just idling for no more then two minuntes

The MTF is wrong.
If you're tuning with Tom, get him datalogs of what he wants and I'm quite sure he'll get it working as it should.
