VVTLi Controller?

Turbos have timers, vtech has controllers but is there such thing as a VVTLi controllers? I mean Vtec and VVTLi is the same thing isnt it? Would it a vtec controller be compatible with the vvtli? It would be great if we could drop our revs down to 3 or 4 to start feeling the lift!

i posted the same question a few months ago. people say that the reason there are vtec controllers is because people have cracked the honda computer codes. perhaps honda gave out the codes or something but no one has "cracked" the toyota computer yet. until we do this, we cant alter the settings on wheh lift kicks in. it would be soo cool if we could drop it to like 4000 tho right? i bet it would knock half a second or more from our 1/4 time.

I refuse to believe there isn't some reason that lift is set to kick in so high in our cars. If Toyota could safely make the car lift from 2k without ANY modification to the engine, why wouldn't they do it? It wouldn't cost them anything and they would have a car that runs 1/4s in the 14s probably.

Gotta be a reliability/feasibility problem there.

Wasn't there a device coming out soon that would allow you to adjust VVTL-i? I thought someone mentioned the name a while back.

I don't think the stock GTS runs in the low 14s, does it?

Dunno, I only see modded-out ones. In any case, my point is that I don't think there is an easy way to put in a chip and change the powerband. Lotus spent a ton of money tweaking the engine to make it 190hp with more low-end torque, it took more than just changing the computer settings.

You are right, there is a reason that Toyota put the lift so high. The reason that lift is set at 6k is because it doesn't make more power than the first cam at lower RPM's. If you lowered the 2nd cam engaugement point to 5,500 rpm or lower, instead of getting a more linear power band, or getting more power earlier, you will instead get a big power loss when lift kicks in. The car would bog down.

No one have been able to crack the factory ECU to modify the lift engaugement. The only device that allows you to adjust VVTL-i is the Apexi Power FC. Like I mentioned above, lowering the RPM that lift kicks in results in a power loss instead of a gain. A member of NC.org (M-Spec) lowered the lift to 5,500 RPM with the Power FC when he was tuning his car and had dyno proven power loss because of it. Instead of lowering the lift engaugement to try and stay in the power band, he ended up raising the fuel cut off point so he could rev higher.

But from reving higher, you run the risk of blowing your engine, right? If so, it's not worth the consequences if you ask me.
