I have read all of the posts about the different ecu's that can be used on this forum for 92-95 civics but in the engine swaps 101 on this site it suggests that for the D16Z6 that, "There are several options with the ECU. Either the D16Z ECU or P28 is used, or the stock ECU is retained and a VTEC controller added." Will the PO6 work or is the timing off enough to make it not run. Or is it that only the ECU's with vtec will work with this particular engine. Please list all of the ECU's that will work properly. This is a stupid question but I have searched everywhere.
