The s300 now has boost control

Damn it. I just bought a Turbosmart dual stage controller a few weeks ago too.

No ****.... awesome

EDIT: Still great but its $50 for Hondata to do it and then another $50 or so to order a GM Solenoid..... not too bad though.

Awesome!!!!

The GM solenoid is normally open, so running it on the top of the gate will require 100% duty cycle to run off the wastegate spring. The GM solenoid's min useful duty cycle is around 10% and max around 85%, so with the solenoid going to the top of the gate, the car will run a little more than spring pressure because the sol. bleeds pressure through even at max duty, it won't completely close the line. Just a note for anyone following the instructions. I haven't done this with the hondata so i could be wrong. There may be an invert option to select for normally open and normally closed solenoids.

From what i gather, this is an open loop system that just sends a given duty cycle, correct? If so, boost is going to change with altitude and weather changes, so keep that in mind.

I'd definitely recommend running a solenoid other than the GM. I've used the Apex solenoid with very good results on my race cars. It's a much better option because it'll function correctly from 0-100% duty and you can run it normally closed. With a normally open solenoid on the top of a gate, if anything fails and it doesn't actuate, the car will over boost. With a normally closed solenoid it will just run off the spring.

How much does the Apex run? I was looking at a Perrin one also but I am not 100% sure if it is compatible or not.

The Apex sol. is expensive, about $150 or so. The Apex operates around 25hz. I'm sure you can find out what the perrin is supposed to be run at, probably something similar. AEM just came out with one too. I'm sure it's just someone elses relabeled, so it'll probably work good too.

I have a personal vendetta against AEM Electronics, everything I buy from them breaks

Tony...

Was this used in AEM or MoTec?

tony1

I've used them with both, why?

RedR

I´m going to wait until someone tests this new feature and gives us some feedback.

Silverbeast

I wasnt for sure if Neptune had started to add the feature as well. If so, then the inverted input would possibily apply in the OBD1 ECU anatomy. I figured the standalones would definatley incorporate the ability and control it pretty well.

In the SManager software it does show to give the option to run a solenoid that is normally closed, which would allow for the Apex or similar. I need to test out one this week.

Hondatron

if this thing is going to to boost per gear that is great, my question i show good is the s300 in determining the gear ? i would love to use this feature just not with a gm solenoid. I do like the Perren unit but i wonder if it works just like the GM in staying open all the time?

tony1

The perrin and aem are 3 way sol. that can be run normally open or nomally closed.

Silverbeast

The AEM or Apex look like either will be solid units for the money. I dont think AEM would have switched from using the GM solenoid to having their own made without a reason.

Hondatron

anyone try this out yet?

Silverbeast

ECU hardware kits came in today. I would expect a full report by this weekend. Dyno is scheduled for Friday. Gear based boost would be scheduled for track on Friday unless the rain forecast holds true for Houston.

Spunkster

Has been running on my car now for 2 weeks with no problems. .5 bar spring and im boosting a very solid 10psi. Max I want to run on stock internals.

Just make sure you put in a boost cut...so you don't over boost while you are stting everythign up and in case a vac line comes off.

Tchleung

Sry to bring an old thread back up from the dead, but tony1, when you said you used the Apexi solenoid in the normally closed postion, was this the same solenodi that comes with the AVC-R? If so, there are two tirse comngi off it, one I'm assumnig is jsut a ground, while the other gonig to PIN A11 I think i was correct? which wire is for which?

EDIT: I just read over my S300 help menus and found installation instructions and foudn taht it says it doesn't matter which way you wire it. one goes to A11, adn other goes to switched 12V. Not ground. good to know!

With the s300 you can configure the Gm Solenoid to run either closed or open.

I know it's old, but what ever happened with your testing??
