Hi guys, I have a LS/Vtec on my car. Some guys told me that I don't have to run a Vtec ECU by connecting the Vtec selenoid to the Apexi VAFC with the LS ECU. Is this true?

 

Yes,

you will need a rpm activated switch to connect to the VTEC Solnoid and the VAFC to adjust the fuel for the higher comsumption rate once VTEC is activated.

Personally, I'd use a VTEC ECU since there are ignition adjustments as well.

 

Yeah, get a VTEC ecu....RPM activated switches suck.

 

I got a chipped P28 ECU, probably need to use it then. The reason why I wanted to run the LS ecu is because it is tuned by XS engineering with a 9100 Redline

 

If you already got a chipped P28 ECU why dont u just have someone chip it so that you can redline at 9k with the correct fuel map... just make sure your engine is built for it though...

 

Do you HAVE to have the rpm activated switch with the vtec controller?

 

???

 

you can run a chipped p28 ecu, and or get an rpm activation switch...you dont need a vtec ecu to run vtec....just an oil line and soleniod...

Peace

higher redline=less horsepower on stock motors. and a ls ecu that was tuned was tuned FOR A LS AND for that motor swaping it over to a vtec motor even with everything else would be stupid

 

A friend of mine put an LSVTEC into his 98 LS teg, and for a while just had VTEC hooked to a toggle switch, not the best arrangement, but it worked.

 

I wanna know what you're doing revving an LS/VTEC to 9100 RPM did you de-stroke it or something?
