Will a dx auto ecu work on my dx head swap on my cx bottom end? My car is a 5 speed and theres a nice auto ecu in a junk yard. Also will a vtec computer work with my setup or will it mess things up because of not ingauging? Witch intake manifold flows better? EX, DX, or aftermarket like OBX?

 

Any one could help me out?

 

i dont know if itll work , but it really sounds like a bad idea, an auto ecu on a manuel , if i was you , id look for a manuel one , about the rest i dont know

 

dx head cx bottom end .. ?? both d16y7 .. auto ecu will work .. d16y8(ex) intake manifold best flowing .. aftermarket im not sure .. also i believe running the vtec ecu w/o vtec .. will throw cels ..

 

I have a cx that I recently put a b7 head on. I have the stock cx intake manifold and I can see the difference in port sizes. But I need a dx or maybe a vtec computer to see full power.

 

Have any of you ever experimented with any of this, Would the motor still run ok with a vtec ecu?

 

The auto ecu will work on your setup. You'll have a CEL because the ecu won't be able to read the auto tranny sensors.

 

I would say go ahead and pick up that Auto ECU from the junkyard. You can have it converted to a Manual ECU and you won't throw any codes. This would be the best alternative for running your setup (D15B8 (P05) bottom end with a D15B7 (P06) Head). I do these kind of conversions, but i'm a little far away from ya. You might be able to find a Honda ECU tuner in your area that is comfortable with modifying it and can do the conversion.

 

So if i have a CEL will it still run allright? And what if I got a vtec ecu?

 

Any one know?

 

It should still run fine with a CEL. I don't think the computer will put you in limp mode for an auto tranny issue.

 

Yah unless one of you already tried it and it ***** up I think I might try the auto ecu before the junk yard clears the civic out. I just cant stand the 5,500 revlimiter of my p05 ecu. I found that the dx head b7 makes 102 hp at 5900 rpms so I am not even seeing 100hp before cut out.
