I was wondering if ne1 had a good website, or even u would know, about how vtec controllers work, whats there purpose, and when should some1 get one.. tell me if i need one....here is my setup:

1994 acura teg, GSR- 1.8L Vtec
RSR Catback exhuast
DC headers
AEM Cam gears
MSD Wires
Akamota Cold Air intake
B&M Short Shifter
...thats my engine mods so far...the reason i ask, is because i was reading a mag, and they put a cold air intake, headers, exhust, and vtec controller,and thats all the mods dont to this integra in the mag. They didnt explain in detail y they did that, or what is was used for, and it was on a 95 GSR...so plz if ne1 has ne info, thanks a lot

 

well u have vtec controllers that allow just to be able to change the vtec point...but u also have things liek the VAFC or hondata that allow you to change that plus fuel and other things when you get it tuned...if i was you i would not do it not unless u got more mods or cams and needed to get ur car tuned...

 

once you get cams,intake manifold and a throttlebody i would say get one
