Well, I decided to save some money and installed it myself. Before I was running vtec at 4600 with a pm7 ecu chipped. Now that the vtec comes on at 5500, it feels stronger! Is it me, or did the VAFC correct the fuel curve? Oh yeah, wat's the COR function?

 

single cam? it is almost always better for vtec to switch later as opposed to earlier. typically, a rough hack tune is done when vtec switches over the smoothest.

 

not a SOHC, it's a b16 with a chipped crx si ecu. pm7, dont' ask me how, i'm in search of a chipped pr3 or pw0

 

CRX Si ecu doesnt have fuel curves for VTEC. this will correc tyour problem mre but id get the right ECU

 

i know it doesn't but the ecu still reads PM7 with a prototype B16a ecu with rev. at 8.5
