Need settings for AEM Tru Boost on Greddy Turbo Kit
Hey Guys,
I have a stock greddy turbo kit. I will be installing a AEM Tru Boost Controller tomorrow. I was just wondering if somebody here has settings for the following:
Alarm Setting (ALA)
Wastegate Crack Pressure (gAE)
Bar Graph Scale (FUL)
Boost Setting A (AXX)
Boost Setting B (BXX)
Is this something the tuner has to do? I've never dealt with a boost controller so I'm completely clueless on this.

Here's the instructions:

Based on those settings:
ALA: Set this to your max boost pressure, if you boost creep for some reason, you want to be notified if your boost is higher than a specific amount. If you're using the stock waste gate adjustment, I believe its 7 - 8 psi. I would set your alarm to 8 or 9psi.
Wastegate Crack Pressure - This is the pressure in which your waste gate is set to open at I would set this to 7psi
Bar Graph Scale - This sets the scale for which the sweeping bar gauge lights up. I'm not entirely sure on this one, but my guess is that if you set it to 30 it will divide 30 by 24 (number of LEDs in the bar) so you get an idea of how far into full boost you are at. In your case I would set this to 7 meaning the very end of the gauge will be at 7 psi.
Boost Setting A - This is the duty cycle of the boost controller. This controls how hard the controller works, and determines the boost level. I found this on a dodge forum on how to tune it:
Boost Setting B - Same as A but different setting - you could set the duty cycle higher for a higher boost level if you wanted to have "2 boost settings" One high or one low.

..Turn the key to the on position and hold the left button for 2 sec. It will display an "A"....this turns on the A map...push the left btton one more time.....push both buttons at the same time should turn on this map.
Now you can set all the other parameters too.
Hold both buttons for 5 seconds and then hold both buttons again for 5 seconds.
You can set your peak display scale and a bunch of other things while in there.....it is best to read the directions and use your common sense to where to set it all at....ex. If you only run 17 psi don't set the outside scale to 30 psi...set it to 17 or 20..............and set the display in psi not anything else.
Once all your settings are right you can start tuning it.
Turn the key back off to save all settings then turn the key back on.
Press both buttons for 5 seconds and it should display A10 this mean boost setting a 10% duty cycle start the tuning process from here.
From this point all you have to do is press the left and right buttons to up or lower the duty cycle but remember always hit both buttons 2 times in a row to save the setting you just set. It will say run when it is saved.
Start the car and go out and start your tuning....sometimes it will take 20-30% duty cycle to get any psi increase in boost.
Run the car and keep pressing both buttons for 5 seconds to get you to the "A" map and then up or down the boost till you hit your targeted boost level and remember hit both buttons 2 times to save...it will say run and then you can hit the gas again and see where the boost got to that time.
At this point it will only spike the targeted boost level and then fall off quickly....you must now tune the wastegate crack setting.
Hit both buttons an hold for 5 then do it again to get into the main menu...hit both buttons till you find the spr/gae setting it should be at 1.0.....hit the left or right buttons to raise or lower it by 1 psi at a time untill you get it to spike and hold your targeted boost setting....sometimes when going in 1 psi intervals it will boost creap above the targeted level....back it down in .1 psi till it spikes and hold the level you want....and remember always after adjusting the crack setting hit both buttons untill the screen says run and that setting will save...
Run the car till you get it right....once everything checks out fine let the car idle for a minute and then turn the car off to save the settings( per aem's instructions but i dont see why it is necessary).
I will get pics up if needed but i think everything is pretty easy....have fun and happy tuning
