Some local Jeeper stopped me at the store the other day and said something that has been bugging me. He told me that his 93 Wrangler 4.0 is being ran by a 5.2 ECM that was out of a wrecked Grand Cherokee. Is this possible?

 

not sure if the the 4.0 is a v8 but if it is i would assume so...

im not to familiar with the different motors other than the 2.2l, 2.5l, 3.9l, and the amazing 5.2/5.9l

 

Yeah, I am having a hard time believing this. Cause he didn't have a sticker on the ECM to get the numbers off of it to find out if it was for a 5.2. But they do have the same ECM connector.

 

The 4.0 is an inline 6. A V8 ECM should not run it properly.

 

That is 100% total BS. IIRC, the 4.0 is an inline 6 right? There is no way a v8 computer could run an I6. Different timing tables, different fuel maps... absolutely impossible.

If you see that guy again, tell him to turn in all his tools cause he needs to never work on a vehicle again!

 

sorry to be off topic but there is a person over here trying to sell off a v8 dakota sport with a ax-15 manual in it saying it came that way from the factory....btw its a 93

 

I didnt think the V8's came with a manual trans as an option in 93. The AX 15 was the manual trans that came in the 4cyl and v6's. The v8s only came with automatics from the factory in 93. If I can remember right that is what the faq said in this section.

 

^ Yup. There was no v8 5 speed option until '94. And the AX-15 never came behind the v8... its too weak. In fact, the v6 5 speed Ram even had the nv3500 cause the weight of the truck was too much for the AX-15.

 

i knew about the 93 v8 being only auto. i found that out in research i did for the swap on mine. the person swapped teh v8 into the truck i know for sure. because in the search done on the vehicle the trans numbers match what the manufacturer had tagged.

 

you dont always have to be gentle... but in the case of that truck i would be untill an nv3500 is put in
