I had a CRX Si with a 14b turbo kit and a obo0 PM6 ecu that was chipped. The program used was turboedit. It ran good, It only had a little hesitation around 4grand.

But to be honest with you. Your best bet is to go obd1. You have much more tuning options then. You wont have to be searching high and low for that certain pm6 ecu that you can chip. And turboedit is way out dated. The conversion is cheap and easy.
