what you think chipped ecu vs. apexi v tec controller "vafc"

 

Use both if possible if you are going to use an OTS chipped ECU and can't specify your own VTEC crossover.

Aside from that, it's nice to have both b/c chipped ECU's have a tendency to run really rich, and you can use the V-AFC to lean it out as needed.

 

yea good idea ima ddo dat see hwo good it runs thanks
