electronic boost controller

[03baggedturbo]

I have been reading the posts for a while now.. I have been saving my pennies and am ready to make a couple big purchases.. instead of going with a manual boost controler wich has spikes I am going with eather an apex or a gredydy (profec e-01) it is a little more but I want to go show and go and would like to have a safe system.. anyways has anyone else tried eather one of those systems yet? also I am going to get a turbo timmer and a blow off valve.. probly the greddy one but we will see.. the greddy also has a 3 hour logged card so you can download it on you computer I think well see..

oh ya one more thing.. so our cars can go 14psi reliable.. 15-16 psi the head gasket and the fuel managment systems fail.. so I could set it at 14 in all gears? I am never quite sure how that works on our cars.. I guess from reading it starts at 4psi in 1st gear then goes up to 14psi in 3rd and 4th.. oh ya.. I have my battery relocation

So, you are ready for the next step???[}]

Here are some things to think about when you are going electronic.

1. there would be a substancial installation phase. Con

2. you should have full control of the boost presure at a given RPM, Gear selection, Vehicle speed. Pro

3. There should be little or no spikes. Pro

4. Data loggin. Pro

5. Would be harder to return to stock for waranty issues. Con

6. Will have cool computer screens on or around your dash. Pro

7. you can monitor Boost, RPM, Throttle position, Vehicle speed all in one screen. Pro

8. Overboost alarms. Pro

9. Includes its own self contained boost control solenoid that can be installed real close to the turbo and wastegate for quick response. no need to use the factory plastic tubes. Pro

10. My favorite, Scramble boost! You can have bosst increase when needed without getting out of your car. Con

The controler that you decide is your personal decision.

Exhaust Depot installed in his SRT the Profec e01

I have the APEXi AVC-R controller.

They both do the same thing including datalogin. I was told by exhaust depot that the Profec is very simple to install with just four cables. Greddy also has the e-manage that conects to the factory computer and to the e01 for complete control of the engine for an aditional $350.00.

what turned me down on the e01 was the LCD screen. Compared to the APEXi it is a huge screen and from what I saw, the screen can only be installed standing up. this means that the only usable place for this is up on the dash, you have to find a place to install the Controler CPU, have a cable runing to it and to the best of my knoledge it can only be adjusted by a small included remote control that can be lost in the tall seats of our car.[V]

The APEXi consists of two major components, the Solenoid and the screen/cpu with an aditional boost sensor that gets conected to any vacuum line on the manifold. it can be installed anywhere on the car and it has a nice hinged mount that makes the controller fold down or up to hide it when you dont want to show it. It has great grafics and is very easy to read. My gripe on this controller is that it is very labor intensive to install and remove because you have to tap into three sensor cables at the computer conector: TPS, Engine speed, Vehicle speed, and install the included boost sensor. also you have three aditional cables that are, the power cable and two grounds. of course you have to also install the solenoid and route the controler wire to it.

after you have installed any of this controllers then is the parameters adjustment phase of the car. I recomend you make an excel spreadsheet with all the parameters and keep track of your adjustments and how the car reacted to them, so in case you mess it you can return it back to the previous setting.

Dont get me wrong, I love both controllers but ended up with the APEXi just because it can be hidden and make a sleeper car out of it.

dam dude I read a lot of the stuff you write.. pretty smart guy... thanks for taking the time and giving me a pro and con thing.. it helps when you are going threw it.. I think I am going to go with the apex..

another question.. kinda.. I relocated the battery in the back.. I am going to re pipe my intercooler and intake.. has anyone else done this.. right now the intercooler piping seems to have realy tight bends in it..

also do you guys do cat back exhaust or just replace the muffler.. cost wise the stock seems pretty big piping..

also what about different turbine upgrades.. it seems like the tubo is perfict now.. no or very little turbo lag..


I am not a millionair but I am selling my other car so I am planning on spending about 2 grand on upgrades while I do have the money.. also all the instilation will be free so it's just parts.. thanks for your imput.. ADAM

I feel funny when people call me exhaust depot.

Anyways, the e01 is cake to install. 1 power, 1 ground and thats it for the powering up portion.

Two vacuum lines to the soleoid. Another vacuum line goes to the pressure transucer.

The e01 has another plug that is not needed but is good to have. It hooks up to a tach signal(need msd tach generator) and throttle position sensor.

As of lastnight, i have the emanage which is a piggy back computer that can contoll bigger injectors and run additional injectors installed. With a USB, you can connect it to the e01 and have it tuned via the e01.

Or you can purchase the additional softwarea dn tune it with that (more features).

The e01 can read A/F readings, temp sensor readings etc with another additional harness.

WIth the additional harness, you have 2 analog inputs, and 2 digital inmputs. YOu then have 2 analog and 2 digital outputs!

So say you hook up the analog one to your 02 sensor, you can convert the voltage to an actual a/f reading. The only problem here is that you need to know what the convertion factor is for the voltage to A/F reading.

YOu can also hook it up to your temperature sensor. At X amount of resistance, it will trigger an alarm if you want it to.

So as you an see this is a great unit and can be overwhelming to some one with little mechanicl experience if you plan on utilizing all of its features.


happy boostin!

Don't get me wrong.

I love the e01! What I didn't like was the screen on the dash and the remote control, that with a two year old in the house, it can be lost. It is more powerfull than the APEXi and you can upgrade it with the e-manage and control fuel and many other parameters but expect to pay up to $1,000.00 for the complete package.

I just installed the A'PEXi this morning and have almost all the sensors operating (TPS, RPM, PSI, Vehicle speed). Is so cool to see all the parameters in that little screen. I have just started the adjustment phase but as of right now, no Spikes! and you will need a calculator to convert from PSI to kg or whatever that metric number is.

What Hector is saying is true. The e01 is simpler to install than the AVC-R but with all the inputs going to the controller, it knows whats happening and controls better the boost. Expect to lose half a day installing and adjusting it and you need to tap into the computer wires for all sensors. it includes all wires,hoses, connectors and fittings. Also, you have two banks so you can set up normal driving and track setting. If you need heelp installing it, E-mail me.

YOu can actually controll the emanage unit with out the profect-e01. The emanage retails for 380 and the software and cable is about $120. The optional fuel injector harness is around $40.

With this you can control your whole fuel setup as well as run additional injectors and leave the stock ones alone. You can also elminate fuel cut which is hen the stock injectors turn off when the car sees to much boost. You can also datalog etc.

I currently have this setup on my car now. My next step is to install my larger injectors, but I will not do so untill i get some voltage readings off the oxygen sensor to see what the stock setup reads. Will make it easier for me to adjust the emanage later on.

With the emnage, when you upgrade your injectors, alsl you need to do is enter the stock injector size, then enter the larger injector size. This will automaticly set it so it runs stock with larger injectors. YOu can then add more fuel uptop where you need it.

THis is not for the average person to install. YOu need to be familiar with your fuel setup and also wiring etc.




IAN, what are you using for a tach signal? The crank position, cam position and injectors are off and do not give a good signal. The camshaft is off by about 150-200 RPM. I had to use a tach adapter to get a solid RPM signal.

[Ian-PT-GT]

The Crank position sensor won't work with the controller. I used the Ignition coil #1 cable and set up the controller as a two CYL engine. The controller operates by reading the pulses to the ignition and our cars have two coils. It is the Black cable and gray line on the orange connector (I will check the manual and confirm the colors and connector) It works perfect! I am still working with the vehicle speed sensor. My PT is equiped with the A/S trany. The manual one has a speed sensor. Hector, see if it works with your controller.

[Exhaust Depot]

I had that problem also. I was getting a half rate when I tapped off the coil. I did not want to enter a false cyl number to get a good signal because it will throw off the emanage portion.

Right now im in the works of making my own tach adaptor and will post up the how toos on my site. Should be about $5 in radio shack parts.
