hey guys....just a few questions
i recently put a bigger throttle body on my 95 ef falcon( went from standard to 69mm) my problem is it wont except the increase in air flow and now it is idling rough and suckin the juice quite quick

my questions are this
1. can you remap a ef series 1 ecu?
2. i was told u can put a el ecu in a ef....i found out the hard way that u cant... is there any difference between a series 1 and a series 2 ef ecu???? if not can you remap it
3. am i better off putting a performance chip in it????

thanks heaps
