When will you start playing the Pills on the cars? is this something you do now?

 

Bryan when are your pills gonna be available? I'm local and would like to try a few things...

 

Put me down for 1...where do I sign up?

 

I wouldn't say the stock setup was 'problematic'. I'd say it performed exactly as designed. The stock pill is sized to limit boost to exactly what it does; it's a mechanical safety device to prevent overboost and therefore probably warrenty down the road.

 

What size pill are you using? #65?

 

Same as the Evo 8/9.

 

Well, compared to the other set of cars Bryan tuned originally...there were only two of us (my GSR and one other MR) that had this issue. I believe mine was more pronounced than the other car..so in my eyes it was problematic because it was limiting boost whereas others were tuning just fine.

 

bryan what are you using for logging?

Edit: nevermind i just saw your response in another thread. I am looking forward to the new boost lines

 

My hunch is the issue was probaby with the actuator itself. Much less variation in the boost control system as opposed to the actuator itself (variability in preload set from factory, actuator spring rate, etc).

But again, the idea for the sizing of the stock pills IS to limit boost

 

Agreed, but it was limiting my powahhh . So for my needs it was "broken"

 

Hahahhaaaa

 

Will the pill upgrade generate the same results as the jun or forge actuator mods ?? Im really curious to know if they basically do the same thing, just a different way to do it ??

 

Sorta.....

The stock wastegate actuator is rated at ~11psi. So if there were no boost control system, you'd only get 11psi of boost.

Now the stock boost control system works like any other electronic boost controller in that the boost solenoid bleeds off air before it gets to the actuator in order to keep the actuator shut to build more boost. Basically, it modifies the 'signal' going to the actuator to fool it into staying shut. Now the stock system comes with these 'boost pills' that limit how much the 'signal' can be modified.

So the modified boost pills allow the signal to be modified more keeping the wastegate actuator shut longer. But there's still a physical limitation based on the spring in the actuator as to how much boost it can hold. So at some point, regardless of what you do to the boost control system, the actuator will still open up because the spring is too weak to keep the wastegate flapper shut.

 

Ok cool, thanx for the break down {thumbup**

 

so here is a kewl explanation of stock evo9 boost control system and where the pills

http://www.accessecu.com/accessport/...ks%20v1.07.pdf

here is the X stock boost control system diagram

i belive in 9 pill near the selonoid was removed so it would bleed all air back into intake and pill near the actuator would be made smaller as to make it think that system was running less boost

so razorlab, question is where are the pills on the X and what to do with them?
