I recently installed my spoon Cams and adjustable cam gears along with springs and retainers.
I have access to a dyno for a good price for a day but will have to tune them myself. I'm gonna give it a go.

My question is that because i'm clueless on tuning them, do i do a base run and then is it just a case of moving the cams slightly from the cam gears?
Which way is retarding and which is advancing?
Which will give more power at top end and which at low?

 

Bump.

 

usually on most B-series engines you advance your intake cam 2 notches (+2) on the cam gear for a total of 4 degrees max and then retard (-1 or -2) the exhaust cam 1 or 2 notches for a total of 2 or 4 degrees.

The dyno is the proper place to try this and you should start at 0 for both cams and move them in the directions I mentioned in small increments. Because I'm not sure what cam specs you are running you have to be careful not to adjust the cam gears to far or you'll start bending valves when they hit the pistons. An experienced tuner should be able to help you determine what the optimal settings are for your car.

 

Thanks, now i need to speak to an experienced tuner.
There is a guy who said he'll do it for me. He's an authorised Hondata dealer but he dosent know much about B series engines.
He thinks that the rocker cover needs to come off every time you adjust the gears.
I told him the black plastic cover can be left off to get to the cams.

in order to adjuct the cams easily you have to take the valve cover off, unless you moon cut the valve cover.
set the cams at 0-0 or like the guy sayd above and go from there..set them at where you like them to be at corresponding them with the power band. Every engine is going to like cam tuning a little different.

 

I have spoon cams so the lift is not that great when compared to say skunk 2?
Therefore is valves hitting the pistons an issue?

 

I would still recomend that you don't exceed +2 intake and -2 exhaust if you're not sure about the specs. You could always try to call tech support for those cams and see what they say about clearances and adjustments to cam timing. I find it odd that the Hondata tuner you found isn't that familiar with B-series motors...what's his background/qualifications?

 

He has an EP3, K-series is where his knowledge is i think. He owns a place called system - R near where i live - http://www.system-r.co.uk

 

Ok, that makes sense, I didn't realise that you were in the UK. Are the B series motors not that common in your area? That Hondata tuner must be new to the business.
