I just did an install on a EBC today (greddy profec a) and it does appear to be working, but I the thing set to deliever 1.1 bar and i only seem to get get .9 bar, i turned it up, same thing, just .9 bar of boost

Now, what could be causing this? weak wastegate maybe?

Anyone shead any light on this for me?

Did you run the lines to it before or after the cycling valve?

Danno

Make sure you've got the controller settings set to 'internal wastegate'...

ian

Danno,

With our wastegates we have to have it set as internal? That could be it because I do have it set as an external wastegate, I'll try that today.

And Perry,

It is still running throught the cycling valve, could that also be the cause of the problem? I was going to pull out the cycling vavle this weekend, but I just wanted to see if the ebc worked first...

Perry 951

If the controller is after the cycling valve, the valve could still controll overall boost... I think.

Danno

It depends upon which device is more restrictive (CV or new boost-solenoid). Since the CV is programmed for low boost, it lets a lot of air through to the wastegate. Then the new boost-solenoid, if programmed for more boost becomes the major restriction... Just change your controller to 'internal wastegate' and you'll be fine. Be careful getting on that throttle though, you'll be quite shocked at the quick boost build-up.

Thanks danno, i'll give it a go, if I switch to a dual port wastegate would I switch it back to external? Or leave it as internal?

ian

Ok, well I think that worked, the one problem is now I can't the thing to learn my boost levels, it worked last time, but this time I can only get the EE error... O-well...

But I was getting 1.1 bar in 3rd, 1.0 in 2nd with lots of wheels spin (its wet out)...

I guess I can leave well enough alone and wait till the dyno day in 8 days to try and dail 1.2 bar in.

Sorry I don't know much about your boost controller. It is just my opinion you should really get the boost dialed in to what you want to run before you hit the dyno unless you want to spend a lot of time$$$ on the dyno.

ian

That is sort of the plan, but I figure the guru set up is good for 15psi, so I should not go running 17.4 psi (1.2 bar) till I make my first dyno run, no point and being lean for 8 days.

But before I get on the dyno i'm going to set it to 1.2 and then I have 1 1/2 hours of dyno time to dial in the a/f mixtures...

Danno

"if I switch to a dual port wastegate would I switch it back to external? Or leave it as internal?"

Yup, dual-port wastegate would want the settings at 'external'. They really need to re-do that manual and use "single-port" or "dual-port" instead of the stupid "internal/external" settings they have now.

"That is sort of the plan, but I figure the guru set up is good for 15psi, so I should not go running 17.4 psi (1.2 bar) till I make my first dyno run, no point and being lean for 8 days.

Ian, I'm sending you a new chip that should remove some of the rich idle and can run at 17-18psi. I guess it's Keith who's got the stock car that'll be doing the chip-comparison dyno runs?

ian

Danno that is correct, the black car is stock as stock an be, and we will be doing all the runs with the different chips in that car (and hopefully if time permits driving impressions with the different chips as well).

Thanks for sending the chip out...

ian

well that didn't do it, it looks like I have leaky headers and perhaps a leaky wastegate, so i'm reaplacing both this week before the dyno day. I'll see how the 35mm tial holds up....
