I just bought a 96 GS-R and it has a AC Vtec controller with a little professor type digital display. Now I use to have a 90 CRX with a JDM B16 in the early 0000s but never had a controller. I was able to play with it and tried 4200 and 5200 and no difference other then gas. What else does this model do? Does it have a redline setting, I want to make sure it is on stock redline. When I was playing with it the CEL came on but cleared after 1 start cycle. This teg has a AEM sniffer, a header "3in" custom back and apex looking can, not sure the brand just know it is not a DC, Greddy etc. I want to put on a adj. fuel pressure regulator to cheat the injectors like on the CRX, will this thing get in my way?
