Can anyone specifically tell me the purpose of the V/T Unmt control? One of the guys at my work set it at +5% for both Hi > Lo and Lo > Hi. I'm running a bone stock B16a2 with a mugen programmed P28 and lost hp after it was installed. My made 148.4hp, with a nasty powerband (needed to replace spark plug wires I guess). I replaced it with NGK wires and the powerband was a smooth, but I lost max hpby about 2-3hp. I made more hp when it was left untouched with the v-afc.......once I leaned out my fuel a bit, I lost hp. I started gaining some back as soon as I leaned it out around the air/fuel 13 line. Untuned, its around the 11 line. Anyone have any idea or suggestions on what to do? Thanks in advance?

 

+5%?!!! seems a bit extreme...


what are your mods?

 

B16a2
denso iridium plugs
NGK wires
stock airbox
test pipe
2.25" piping
DC2 muffler
Mugen programmed P28

Here's my air/fuel run as is........(this was before the V-AFC/ NGK wires were installed). Whats the reason for the VTEC Unmt control? The manual doesn't seem to explain what happens when it's moved +/- for hi-lo/lo-hi? Is there any harm right now, if its at +5????
