Did the R2 cams improve spool over your last setup?

 

No but I gained 45whp in the mid range and 30whp up top with 2psi less boost.

 

Hey all
Been reading through the thread and wanted some opinions on my setup. I've got GSC R2 cams with a FP Black on a standard bottom end. I'm using a tuner supplied mivec map which is the same map as his tuned stock cams map (similar to the RS map). I'm getting knock from 6200 through to my 7500 redline and a bit even after I lift, this is not fuel or timing related. Do you think this could be to do with the mivec tune and if so what map do you think I should try, was thinking John Bradley's S2 map?

 

Definitely MIVEC. I got like 1-2 counts of knock with the stock JDM map, I increased from 5000-7000 up a little, knock went away and picked up 10HP.

 

I've finally gotten into adjusting my MIVEC map. Here's what I've got so far.

 

Since you are using my style of map already, at 8250 set the advance to -1.2* from 145* load and up, drop the advance at 5000 from 14.4 to 9.0, then interpolate that whole block.

 

Thank for the info!

 

John Bradley is this map for stock cams only or can it be used with almost any cam?

 

Hey Aaron, originally this was your map that you put in 4 years ago. I've been playing with it a bit. I was thinking of e-mailing you, but I know you're super busy. Hows this look? I won't get to test it for a while since the snows started.

 

Almost any cam as the centerlines typically are very close on most of them. Some of them need less advance sooner (i.e. Cossie), some can hold more longer and make more torque, etc.

Looks pretty close to what I would use, yeah.

 

with this map how is partial throttle knock?

 

I dont have issues with partial throttle knock. How much boost and is the car surging or BOV cycling while you see knock?

 

In most cases its during buildup of boost in the 65-90 load cells so 0 -15psi

I havent noticed surging while this knock happens although i had to readjust the DV because it would open early in 5th under light boost (passing on highway)

 

Resurrecting this, hope you don't mind

I went through the thread and produced an updated map for my car. This is a combination of some of the maps here as well as my original top end map.

This is what I'm running now and I can believe how much better daily driver the car is with this low end change only.



This is what I'm thinking of adding once I have changed my original catbat to a less restrictive 3" catback with 3" DP and stock cat.



Thoughts so far?

 

For a less restrictive exhaust, more overlap is better out in the high load cells. But don't go crazy with the overlap. What's shown in the first table is probably fairly appropriate. It will depend also on what turbo is being used.
