Cas Setup For New Engine

[Single]

Mods if you want to move this go for it.

So ive finally finished my build and my engine will start and cough and splutter and it has a pretty good base map setup because a Genius from haltech did it for me.

my problem is i moved the cas after he told me to change a couple of pieces and now im unsure about its position.

i have a laptop with all the tunning software on it but just wanted to know what reading or where is the best place to have my CAS (in other words should it be at full lock left or right) or in the middle?

if some one has what reading it should be coming out with that would be preferable

engine is a rb26/30

stock cams

stock cam gears

is there anything else you need to know?

Base timing is 20 degrees for a RB26, you will need a timing light to adjust properly.

exactly. need to set it's position with a timing light. no way to tell you where exactly it goes. you should always mark it before removal to at least get you close to where it was when replaced. every car is different.

allright i understand, ill go to my workshop and get one on it.

there isnt any other reading it should be producing like the TPS @ .45v closed?

i couldnt really mark it anyway as i pieced this thing together

thanks for the help

Best place to start is with the CAS in the middle. As you try to start the engine, you could make minor manual adjustments to the CAS's position so that you get a smooth idle. Once the engine is up to temp, get the timing light onto it.

agreed, with stock cams and cam gears start in the middle until it is running then use a timing light.

cam gears on a standard cam you will probably have to turn it almost all the way right/clockwise on normal/common settings

if you have the tuning software then plug it in and see what timing the ecu is spitting out at warm idle and adjust the cas until it matches the crank
