I got problem when i reconnect my VAFC to my ECU, PWO again. All of the wirings is correct. When engine is idle, i check my Vto is OFF on VAFC screen, but when i rev it till vtec engagement, vtec is engage.
Anybody here did faces this kind of problem?
thanks.

 

What the problem is, VTO means vtec out. Its only on when at the rpm you select to engage vtec and after. Even in at a stop. VTI is vtec in, when the computer wants to do it. Yours sounds like its working just fine.

 

Ok...i understand now. VTo means VAFC switch vtec and VTi when ECU switch vtec.
My cars running good.

Another question. What does it mean by Narrow Throttle and Wide Throttle?
Should i sets my Narrow Throttle same with Wide Throttle? ( in fuel enrichments percentage ).

Thanks for your concern NC - B17A. But i do have this APEXi Manual already. Itt not answering my question. I'm just wondering what does it mean by Wide Throttle and Narrow Throttle. And should i sets both with the same percentage of fuel enrichment.

 

Well, if you read the manual he is referring you to, then you'd understand how the Narrow and Wide throttle functions work.

 

Narrow is normal driving
Wide is hard throttle.
You should set them as your car needs. A dyno with a wideband O2 is the only way to tell the best settings for sure.
