okay i bought a motor swap and a crx shell from a kid i port charlette fl. the motor swap i bought was peviously in the crx but was taken out to be used in another car but never was so the crx was already wired for the b16 since it was aleady in it. i put the motor back in, the motor runs strong but for some reason v-tec engages at 3800 rpm's im runnin a pr3 ecu that came with the swap. for what reason should v-tec be engaging so low. any ideas why this is happening.oh and the ecu has never been chipped.

 

dos eit have some sort of v-tec controller?

my b16 rex hit v-tec around 5200

I think 5200 is near the stock engagement point.

BTW, how do you know it's engaging that early? Do you have a VTEC indicator wired up or something?

 

no man i dont know why it hits so low. i have harness wired for b16a and pr3 ecu thats it i was thinkin of trying another pr3

 

what cluster/tach are you running? I could be mistmatched

 

im pretty sure its just the crx si cluster
