when you get the jun head package and the ecu. you set the cam gears at 0,0 correct? its tuned then? someone please explain. yes, i searched. and jun website isnt working and its too late to call. thanks.

 

well..i don't really understand wat you asking...but if the cam gears set at 0, i think it's not tuned yet.

 

i thought that i read that with the ecu and cams and head package. there was no tuning involved other then setting the cam gears and 0,0 . thats my question. please no flames.

 

JUN recommends you leave your cam gears at 0,0 and your fuel pressure at 40-42 psi *with the vacum line on*

 

When I spoke to JUN, they also recommended against installing a V-AFC with their ECU. They also said to leave the cams at 0,0. In this case, the only "tuning" to speak of would be adjusting fuel pressure and ignition timing.

 

Well, the documentation that came with my JUN cams say not to advance the intake cam more than 1 degree and not to retard the exhaust cam more than 1 1/2 degree. I do not think that there is much gain since the range of adjustability is so small.

It also says that the cams cannot be used with oversized valves.

 

well.. JUN ppls are weird... i ordered a ECU like a week ago, and they said there are different kinds of them, for regular TB, or for ITB...i just don't understand..cuz the ignition timing should be the same, and fuel should be able to tune with V-AFC...just feel werid.. anyways...so they recommand to set cam gears at 0 when using their head package and ECU? or they ment need to retune the cam gears?

hope someone can really explain all these for me...im confuse...
