Default AMS 500 EBC

Hey,

After searching around I found AMS500, I understand that it is highly recommended and it gives a very very stable boost curve.

It uses two solenoids in order to do that (the only EBC that I know that does that)

Anyway, I emailed them and got an answer that I need a dual port actuator (I use internal wastgate)

I got a few questions:
1. Is it an over kill for my setup ? 15-17psi top
2. What dual port actuator would you recommend?
3. My current actuator got two "ports" technically.

after a quick check I can tell that the bottom compartment is not air sealed... (must it be ?)

You have a Megasquirt. Why in the world are you looking at a $1300 boost controller when you have access to a $60 or so boost controller kit that is likely just about as good?

it's a 400$ EBC, I would like to have 3 modes EBC, MS gives only 1 as far as I understand.

i was using the AEM tru boost, worked great, has multiple modes and scramble boost. Best was that everything was right in front of you on the gauge. So if you started over boosting due to weather conditions, you could adjust it without a laptop.

I've used AMS products drag racing in the past (ams1000) and they are nice. That said I would look to leash electronics now if I wanted a standalone controller.

No weather boost change problem with this unit

AMS is a nice unit, but almost pointless for IWG, especially at "moderate" boost levels. AMS dual port configuation works best for EWG with two ports. Able to hold the gate closed longer, aiding in spool, then open to exact boost set point with zero oscillation. You won't be bale to do that with a single port IWG, so it will take some finagling to get it to old the gate closed long enough to impact spool, while not creating a boost spike.

so let me get this straight: you spent 400 on a boost controller, when you could have upgraded your MS1 to a MS3x for the same amount?

yikes

Well, I hope its worth it. I cannot comprehend doing something like this, but at least you got a really nice product and not something stupid.

Plus, an MS1 CAN be tuned to give good closed-loop EBC in any weather. There's a sticky on how to do this.

This doesn't make sense unless you just like adding expensive parts.

Probably not to late to return new, uninstalled parts. We're talking a new set of Rivals or RS-3s here.

OP said he wants 3 boost tables/levels.

For some retarded reason. Cant the MS3x do at least 2 switchable boost tables?

I'd have just got a 5way noid to match that 2 port wastegate actuator rather than running 2 3 way noids. I bought a 2 port actuator specifically for that reason so I could have better part throttle boost control by using a lower pressure spring and still get high boost by pressurising the 2nd port.

I've got 2 levels with my 1st gen MSPNP. CLEBC and wastegate-only. This provides a lower-boost failsafe when I run out of water injection fluid on track (right around minute 27 ).

Honestly, not sure what I would do with 3 levels. I guess E85 vs. gasoline vs. ???

MS3 will allow 2 switchable boost tables, so you could have EBC 1, EBC 2, and EBC off (spring pressure) for a total of 3 boost levels.
It also does boost by gear, speed, rpm, and time after launch.

These expensive aftermarket controllers with dual solenoids are generally used on drag applications. They use regulated compressed air or regulated CO2 instead of manifold pressure to control a 2-port external gate. This allows the controller to dial in less boost than the gate spring during launch by applying air or CO2 pressure to the bottom port. After launch, air or CO2 is directed to the top port to increase boost.

2 pressure regulators are used. The top port is set for higher pressure than the bottom port.

This allows for really fast reacting boost control, very important for bracket racing. Not ideal for HPDE or road race due to limited supply of CO2.
