I've been looking around the web and through the AEM manuals and can't find an answer to my question. I'm currently looking at boost control options for my AEM series 2. Prior to purchasing the AEM, my car was using a TurboSmart E-Boost 40 boost controller. Out of no where the gauge went dead. Sent it back to TurboSmart and was told the gauge unit was dead and too old to repair. So, I bought another E-Boost 40 since the old one lasted 7 years. Anyway, I now have the boost control solenoid from the original controller and the complete E-Boost kit.

If I'm understanding the AEM setup correctly, the AEM must be able to control boost in order to correctly setup and control anti-lag. If this is true, would it be possible for the AEM to control the old E-Boost solenoid? If not, what solenoid is best to use with the AEM for boost control function? Or, do I simple install the E-Boost?

Thanks!
Matt

A lot of companies rebrand the mac valves.

This is the valve they use:

Standard 2 wire, 3 port.

If your solenoid is 3 ports, 2 wires, you should be able to use it.

Looks like it uses a MAC valve, like what AEM sells. That solenoid will work perfectly with the AEM.

Thanks for the info guys. I just spoke with a tech at AEM. He stated that it 'should' work. At this point I need to get the frequency of the TurboSmart solenoid and then I should be able to set it up.

What are you guys thoughts on having the AEM control boost overall? As well, does the AEM HAVE to control boost for anti-lag to work correctly?

Matt, I ran the GM Boost control solenoid for awhile but when they fail it goes max boost. The Mac valve you can find online at a good price and they fail at Minimal boost. I know my anti-lag was rock solid and the minute my boost control went wacky I lost all control over the Anti-Lag and I could not control the boost. I was launching last year at 45 lbs of boost. The Mac valve is the same as the AEM and they are 1/8 npt ports!

You can run this solenoid at 31Hz. Set this at 32000 μs in AEMTuner.

John - I remember some of the boost control issues you were having. That's one of the reasons why I'm a little worried about having the AEM control boost. Since I have a very nice stand-alone boost control, I need to make sure the AEM is as capable or better than using the E-Boost.

Kurt - That's the same frequency as the one AEM sells correct? I tried to call TurboSmart yesterday but never could get through to a tech. I may e-mail you again for some help on this .

Thanks!

 

[Kurt]

Yeah, that's the frequency they suggest. It's actually not too critical, but should be somewhere around that rate.

I like how you can set boost level by gear, tps, and engine speed. I use all these together to help with traction. I set the tps table to add 10psi at 100% throttle, and add to that whatever the tires can usually take for each gear. If I feel wheel spin, I can lift a little and drop boost.

 

[TurboMatt]

Wow, that's great info. How about selectable boost levels? I know you can set two off of a switch. Is it possible to have a multi-level switch for several levels of boost?

 

[Kurt]

I seem to remember something about a 0-5v input that could be configured for adjusting boost level, but I've never set anything like that up. You can have boost by gear/tps ect. setup and also have a switch for a higher boost level if you want. It would be set at that one level regardless of gear. You'd have to switch it off to go back to boost by gear.

 

[TurboMatt]

That would be pretty slick. What I would basically want is a base boost (18psi) for most of the street driving with the option of raising it to 28-30psi. The car will be run on e85 so there should be no issue with those boost levels. For the race track I would plan to run a more agressive tune with higher boost. The purpose would basically be so I don't need my laptop all the time to just switch from sane to fun boost levels while on the street. So ultimately there may be no need for a multi-position switch as my race tunes could be loaded at the race track.

From TurboSmart:

Straight from lead engineer in Australlia. “When the solenoid is connected to the E-Boost controller, it operates at 25 hz”

Hope this helps!
