i am going to put a z6 head on the A6 in my crx and i was wondering what my tunign options are whiel im still running a chipped OBD-0 ecu. from the search i came across a few ran a PG7 map wich is the 89 integra ECU. i know a lot of peopel are goign to say to go to OBD-1 but im doing that later on when i come back from vacation. i just want to run it with a chipped OBD-0 temprarily. what woudl be a good redline and stock scrossover point for the stock Z6 cam. i was also wonderign if anyoen tried those low buck vtec controllers they are selling on ebay? looks like a nice little gadget to run till i do the full OBD1 swap.
