I have a 91 accord lx I blew the motor and bought a 92 ex motor I put the motor in all ready just need to install the clutch . I still have my lx ecu will the run or start right ? Or do I need the ex ecu or are they the same thank you

 

It will run better with an EX ECU.

 

If i use the lx ecu for alil bite what would it do to my car. hard starts, rought idle etc. or it will run good but not as good a ex euc would do (performance wise )??????????????????

 

It should run good. Did you get the intake manifold for the EX engine as well?

 

It should run fine, except for being governed.

 

yes i got the f22a6 which has the daul stage runner intake manifold . (92 ex)

 

Is it manual or auto, and what about the ECU?

 

Well I am going to be using my lx ecu isnt the ex ecu better . performance wise and even normaly driving.

 

I believe you will need the EX ECU to open the secondary intake runners.

 

okay so i f dont have the ex ecu it wont open the secound runners and m car wont be as fast.. how the the f22a6 daul stage intake manifold work >>>???

 

dude you are on the same BOAT as me. I asked this EXACT SAME QUESRION like 6 months ago.
*do search under my signature name!
*you don't need the EX ecu bro. You will not feel the diffenence at all.(trust me i did an experiment with swaping 93 lx and ex ecu)
-The only difference that you can feel is above 5k rpm.
-even then it's not worth it.
-I've been driving my 93 JDM ex motor for about 30k now with my older ex ecu and have not had a single ECU related issue.

but if you want to fork over the money then go for it. wouldn't hurt performance.
I have an auto & i i never beat on my car so..... i didn't feel the need to get one.

hope that helpd
