Hi People

I've read how to do this before on this forum but i now can't find it i was just wondering which way do i turn the camgear to get it advanced, is it clockwise or anti clockwise and the same for retarded???

Cheers

anthony

If you turn the inner section clockwise (ie rotate the cam clockwise without moving the timing belt) you will have advanced the cam timing. Inlet is same as exhaust. The camgears should have it marked on them....

I honestly don’t see the point in spending a shyte load of time degreeing in the cams perfectly. When all I am going to do is keep changing the cam timing on the dyno until I get the desired power result.

Sure if I am doing a single cam in block engine (like the Commondoor Cup engine last weekend) I will spend a great deal of time with the degree wheel and dial gauge getting the cam timing exactly to where it has proven to produce the most power previously. But that’s because I can’t change it all that easily on the dyno. Plus I know where it developed the best power before, and, since it’s a control engine spec, I know it will develop the most power again at the same cam timing.

But on DOHC engine where it takes minutes to change the cam timing on the dyno, I only see it a waste of my valuable time.

:ermm: cheers :O

I hear what your saying Gary.

But I like to know where Im starting from when advancing or retarding on the dyno. As you know factory marks could be a couple degrees either way. There's no real advantage like you say - but its piece of mind. I look at it as just one of those things that shouldnt be overlooked, like working out your comp ratio and piston to valve clearencesetc. But thats just me :-)

i got so mad results with

rb20det

retard exhaust by: 3

advance inlet by: 1

everyone too tight to share results

Thank's for the reply. it would be good to know what settings people are using and how much power they got out of the cam gears also did this setting bring boost on earlier or did it improve top end ???

problem is - if your cams havent been degree'd in properly than me saying 2 degrees advanced or retarded made all the difference might not get the same result for someone else as there cams are in different positions on the factory marks.

So best thing to do in your situation is like Sydney Kid said - just play around on the dyno until the desired result is obtained.

      RB25DE NEO with Haltech ECU

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
