Boost controller or EMU

[2J-240]

I currently have an apexi AVCR boost controller for my car, it works well on my SR but im about to drop in my 2J and the new EMU. I was wondering what you guys thought about pros and cons of using the AVCR instead of the EMU to control boost. I was thinking about using the AVCR to control boost and having limits set up for the EMU to limit if i overboost. I just like the ability to be able to change boost at any moment. what do you guys think?

Kyle, i was using Apexi AVC-R some 10years back, and i was never happy with that. It was inaccurate, and the final boost did changed over time.

There is no reason for using external boost controler.... only visual .... if someone want BlingBling unit with OLED dispalay .. OK fine

You can use MUX swith input, what will "kill" one analog input of your EMU but gives you 3 independent swithes. And one of them can swith your boost mapping. If you have such sofisticated unit like EMU, you want that it makes everything for you. Also its cheaper. You can also make some "stepper" switch and make more steps of boost level using scaling in boost control...... You can change boost level deppending on gear, vehicle speed, coolant temperature etc etc... this will AVC-R never do.

Some time back i sold APexi AVC-R, S-AFC, PowerFC, all the Innovative lambda gauges, and other ricer things, and used this money to buy new EMUs ...... i was impressed, because i saved some money, and everything works better now.

Karel,

Thank you for your input, that makes my decision easy; sell the boost controller and use my EMU, I will be using a rotary switch hooked up to my a mux switch so that I can have 3 different boost levels. my electronic boost controller only has 2 settings plus wastegate spring so thatll give me a whole extra setting! and itll be all old school like

Chris72 recommended this and it works great:

Try one of these connected to the gear sensor input, if you are not using gear input for any other strategy... it will give you 5 boost settings If you really need that many.

AEM offers an 11 position switch as well, but ECUMASTER only has up to 7 gears in software at the moment.

Another benefit to using the ECUMaster boost control, is it is duty cycle based, so you can run a 4-port solenoid if you need a wide range of boost levels (run a smaller WG spring and still run stratospheric boost levels) it requires you to cut the DC in half or more with a 4-port.

Thanks!

I just ordered on of those switches, they are super cheap! I do have a question though. Ill be wiring it up through a gear input on one of my analogs, what does the physical wiring of the sensor look like? will I be supplying 5 volts to the switch and 5 different resistors on the analog going back to the analog?


Thank you!

Kyle,
Now that you mention it, I think that is the wrong switch. The one we had was 3 wire, 5v sensor gnd and analog input. This one looks to be 2-wire... I'm not sure how it would be wired yet.

Let me see what I can find. According to my customer the switch originally came from Pro-EFI, and he sent me the link to the 2 wire switch thinking it was the same thing.
In the Meantime AEM sells a 12-pos switch that is just about the same price, I just didn't need 12 settings...

I had ordered it before you said it might be the wrong switch, Ill take a look and report back on it so that people may know if they can use it in the future or not.
