what ecu should i run for my swap...its a 96 LS engine in my 92 cx hatch....would the P74 ecu work well with my engine?? cause thats what the "Honda Performance" book says.. any ideas

 

honda performance book? lol

p74 is the correct ecu to use.

 

alrighty then.. P74 it is...

 

What's the difference between P74 and P75?

program wise nothing, but internally they differ motherboard wise.

cxhatch02,
You can also run an OBD1 PR4 ecu and even a (reprogrammed to LS spec)SOHC DX/P06 ecu to power your engine.

Here katman...how would you do that? I wanna know how that is done.

Is it a chip or what?

 

yes, its all in the eprom chip.
An LS reprogrammed chip & then installed on a P06/DX ecu basically converts the P06 to an LS ecu. That simple.

 

what would you get the reprogram chip at? Just any place that chip ecu?

a very special place

You can either buy one from somone such as me, or try FRYES for blank eprom chips.

are you trying to probe/ping me reprogramming info? lol

 

would the PR4 work with my set up???? boosted LS??

okay then...cool

 

would the pr4 work also?? cause im gonna be using hondata S200 next year....or should i go with the p74??

 

An OBD1 PR4 should work, also a p06 (non-vtec civic) ecu will work, so will a P28 (but you won't need the vtec circuitry, so only if you find one really cheap.

Or a P74/p75



Hondata will be reprograming the ECU's, so basically it is only a vessel for the software.

Here is another helpful resource.
