Default How easy is it to convert a obd 0 PR4 ecu to obd 0 Pr3 / Vtec ecu???

is it possible to just put a Pr3 pyr chip in a Pr4 to convert it to VTEC or is it more difficult than that?

i was told that you could not take a non vtec ecu and chip it to a vtec ecu. so my advice is get a pr3 ecu. just lettn u know what i was told.

If you send your ECU to Zdyne, they can convert a PR4 ECU to handle VTEC. It will cost a bit though.
