I have a b16 in my 91 GS and the guy who I bought it from somehow set the vtec to engage at 4200, this is to low. Ive been told that vtec robs torque on the low end. Is there a way to adjust it higher, say 5500. Can I do this manually or do I need a controller.

 

damn....you sayin that makes me wonder if mines is too low, and mines comes in at 5 grand, but i was told just to get a v tec controller...unless you know someone who can tune your computer.

 

is the ecu chipped?

 

Vtec Controller

 

the ecu is not chipped. Also ive looked at a few vtec controllers, The Vcon by buddy club (cheap route) and the vafc from APEXi. does anyone know if the vcon is any good and could a non profeccional wire it up themselves.

 

well if your looking into "only" adjusting your vtec...then just go with the buddy club vconn. also the vconn is user's friendly..by the twist of the **** you can easily adjust your vtec engagnement as oppose to the apexi which requires more technical adjustments which is a bit more complicated.

 

is your ecu stock or what??? u probably using a wrong ECU.. other than that.. get a VAFC, a bone stock ECU, or a chipped ECU /thread

 

my ECU is OEM

 

i dont see how your vtec x-over can be that low if you're using a stock ecu. it has to be chipped or you're using the wrong one.

 

i see what your saying here. Im not to good with ecu ****. Im not shure what ecu im using really. As far as im aware of there are not vtec engines that engage at 4200. So maby it is chipped. How can I tell?

 

What kind of ECU are you running? (P28, P30, P72?)
