Right now I'm running a 94' LS Integra ECU with a D16Z6 engine in a 91' CRX Si with Greddy Turbo at 5-7 PSI. I have the ECU piggybacked with a SAFC but from what I am reading it is a lot better to chip an ECU and tune the ECU. What will be needed to chip an ECU? Or Will I need to buy a new ECU and chip it? Also while Im asking things, will elevation effect my Air/Fuel or will the ECU just adapt to it? If any body could help me or point me in the right direction it would help a lot.
