is there a controller out there that lets us tune our variable valve timing and lift control? like vtec and vvt controllers for hondas and toyotas?

 

you're gonna need this:

 

Uhhhh, you do know that ECOTEC is not a system like VTEC right? ECOTEC is just the brand of the engine. Like.."Northstar V8" etc. And to my knowledge there are none....

 

uhhh....

<looks at his 2.4 VVT>

 

I didn't say anything about the VVT. I was letting him know that ECOTEC isn't the same as VTEC, and there aren't any controls for them. So

 

i understand ecotec is the name of our engines, however last time i checked we dont really have "brand" name for our variable valve timing technology, was trien to keep the question as simple as possible to get a simple answer, ty

 

hptuners might be able to lower the rpm it engages @.. but i do not know for sure.. i dont even have a 2.4

 

well, i'm pretty sure the 2.0 doesn't have vvt

 

oh ****.. this guy has an ss s/c? i just assumed he had the 2.4

 

+1. I'm very interested in his response!

 

Why wouldn't the 2.0 have variable valve timing technology? Now days what engines don't have it?

 

cause it dosent. lol

i think cause the vvt brings in more air and raises the compression. when you have forced induction, you dont want higher compression.

 

they cheaped out,the next cobaltss will have vvt,like the Sky and solstice.

 

It's because they used the LSJ race casting for the 2.0 which doesn't accomodate for the VVT components. The head was originally designed for the dragstrip which has no use for the extra weight, added complexity and low-end drivability and fuel economy.

 

Having opened up, worked on, and ported the LSJ head. I can assure you, 100%, the LSJ (2.0L Ecotec) DOES NOT have VVT.

 

ok i got ya, i knew the gxp solstice have vvt in there 2.0, i figured we had similar 2.0's but i guess not

 

Those motors are also direct injected, while ours are not.

 

I actually have a used ecotec controller it came stock on my lsj. I upgraded mine so if you want I'll take 50 ricer dollars. I accept pay pal.

 

The Variable Valve Timing in the ECOTECs are not a profile change like VTec or MIVEC, the ECOTECs use cam phasing technology.

A "Vtec Controller" would change how soon the change in the cam profile would occur. Cam Phasing is constantly changing. It's completely different.

Of course like pointed out, LSJs don't have VVT, the LNF does.

The following ECOTECs have it: LNF, LE5 & LAT

 

i thought this thread was a joke, the op must feel dumb
