can I try pmt1 to xle4 pcm

[melmount]

I have a pmt1 in my 01. I was wondering I have some weird issue and i wanted to try my wifes early 99 xle4 computer just in the driveway. I was told i can use mine in hers but not the other way around? Can i briefly run the xle4 to listen to my injectors?
please let me know,. I dont want to fry my wifes computer

Or how about a pcm from a stick shift truck? Will it idle my auto truck in the driveway?

you can put a pmt in your e99 but not the otherway around.

i just put a pmt2 in my e99

What happens if put the old style xle4 in the 01? Just want to see it idle? Would it let me?

The last person that did that on the org either had an issue of it starting or driving. I dont remember tho.
