So does this mean that engines with the programmable camshafts do not have the physical metal camshafts? Is it present in the current Lancer GT?VVTI, DVVT, 2nd Gen MIVEC, iVTEC... These are actually programmable...
The cams duration are are controllable via the electronic variable pulley. Which can be mapped and reprogram depending on expertise...
Example, Kiggly successfully installed an EVO 9 cam pulley into an EVO 3 and program it to vary the duration increment vs RPM for his drag application with a Haltech E11 v2(previously)
Nope.. Camshaft is still camshaft. The basic duration of the cams are still there. But the duration is no longer solely determined by the cam lobe alone. It can be advance/retard electronically via a motor mounted on the pulley.So does this mean that engines with the programmable camshafts do not have the physical metal camshafts? Is it present in the current Lancer GT?
Vanos from BMWhow does programmable camshafts work? any source/link?
Programmable variable camshaft....i think the right word is "variable" not "programmable"...it will make much more sense...
i think the correct term for that is "cam phasing"...programmable sound a little off to me...Yup I know about the ability to advance or retard the cam timing. But I wanted to know if programmable camshafts mean that it's possible for the ECU to change the cam duration on it's own. At least that's what I thought it meant by the word "programmable".
i think the word u searching for is 'Regrind'..Great diagram! BTW, another question based on your diagram. Reground cams would have lower lift than the stock ones right?
Regrind cams' lift can be regain to original by spacing up with specific spacers provide by cams grinder.Matspeed's camshafts are regrind right?
