vtec controller for FD1

so we can tap a light eh to indicate our 'vtec' behaviour?
hehehee

I have no idea TBH..

If so you'd be vtec'in when ur crusin not gunning it lOL

i get that vtec "boost" when i gun it everytime

There would be a "boost" although very slight... i'm not sure how your measuring this or so but on my dyno sheet the curve is quite linear with a very slight "boost" at 5500-5800rpm.

So there is a slight boost but it aint VTEC =[

hmmm... interesting

was reading the tech specs of the R18A engine at http://asia.vtec.net/Engines/RiVTEC/index.html

so all in the all, VTEC is engaged btw 1000-3500rpm runnin on low cams and VTEC is off when operatin on high cams, above around 3500rpm... and thus its called i-VTEC (VTEC only engaged on certain driving conditions) and not the usually VTEC which opens after a certain rpm point.

also goes on to say VTEC is never engaged when driving aggressively

thought it'll post up this pic below

I wish everyone would read that link.. so sick of the same questions :P

quick summary above if ppl dont wanna read the entire article

hey guys im new to this forum um in terms of vtec controller friend of mine said that if its activated b4 high rev the engine really lags, there's a reason why honda made it to come in at high rpms... its that true cuz im geting a vtec controller as well soon.

^^use punctuation (i understand what you're saying though)

I think you're thinking of the old performance VTEC though.

OUrs is VTEC for economy - use lamer cams to decrease performance when ur not using ANY engine load (cruising etc)

ProCRX88:

On a car with the traditional vtec, a vtec controller will not be any use in terms of power gains on a stock engine. Normally after an engine has been modded (Intake/Headers/Exhaust) you may be able to squeeze a little extra power by advancing the vtec crossover point.. but yes, on a stock engine it's pointless.

On the FD1 (as this thread is FD1 - r18a engine specific) the implementation of vtec is very different (read the link above)... there's NO certain crossover rpm like old school vtec.. and it's totally different anyway.

oh okey thanks guys, um here's what iv done to mine so far its a B16a2:

-Spoon Cams (Int-256 dur. / 11.5mm lift Exh-245 dur. / 11.1mm lift)
-Spoon Cam Gears
-Toda Valve Springs
-Crower Valves
- Toda Retainers
-stock ecu )
-LSD
-5zigen header (4-2-1)
-KOYO twin core alloy radiator
-stock bottom end
-2.5 cat back to Xforce Varex Muffler

Hw much power gain if i used a Vtec and air-fuel controller?
