I wanted to install an EBC(Electronic Boost Controller) that I can control from the ECU for a long time now, I noticed that there is "Boost control" circuit on the DIYPNP.
Upper left corner, between the MAP sensor and the DB9 (COM) connector.
The Boost control circuit is needed only when using outputs that can not drive the solenoid directly, PA0,PT6 and PT7.
I had ALED output available that can be used directly to control the solenoid.
OK ? great.. but ! I noticed that I can not select ALED as the EBC output...
Turns out I need to upgrade the firmware. to 3.4.x I was at 3.3.2.
***Using ALED for EBC does not work yet - bug reported, hopefully on 3.4.3 Beta2 and above it will work right.***
Quick workaround was switching between PA0 and ALED outputs, using PA0 for EBC and ALED for fans.
PA0 must go to "Boost Control" circuit.
PA0 -->Boost IN
Boost Out---> EBC pin
So, first thing to do is to upgrade the firmware, then EBC wiring on the DIYPNP and then TS(Tunerstudio) EBC setup and tune.
DIYPNP firmware upgrade:
***IMPORTENT***
First thing to understand about the firmware upgrade (any firmware upgrade on any device) is that you are about to erase and rewrite the most basic component that makes this thing alive.
If something goes wrong the device is unusable (sometimes there are ways to revive it but most of the time you're F***ed).
Be sure all the connections you made are good, power to the ECU, RS232 cable.
Make sure you use the right firmware, and make sure you choose the right options when you upgrade.
When you upgrade do it slowly, read everything in the upgrade process, and if you are not sure **DO NOT DO IT**
Ok then, lets start.
First thing, download the right FW(firmware):
http://www.msextra.com/downloads/
Make sure your ECU is connected to the PC/Laptop.
Just before you continue, make sure you have a copy of your last good tune (MSQ).
Now run: "ms2loader_win32.exe"
I upgrade the ECU on the table (out of the car) with an external 12V connected to it.
If you try to upgrade when the ECU is in the car, try to follow the instructions/warnings on-screen.
Now, press ENTER.
Press ENTER.
Press ENTER.
Press ENTER.
Press ENTER.
Choose "y" and press Enter
FW upgrade is commencing...
Next thing, fire TS and connect to the upgraded ECU, could be some errors and warnings, you can view them, anyway you should load your last tune and make sure all settings are right and in place.
You can now find ALED under "Boost Control Pin":
***Using ALED for EBC does not work yet - bug reported, hopefully on 3.4.3 Beta2 and above it will work right.***
Now for the internal wiring...
BTW:
The new upcoming Tunerstudio 3 will have integrated FW update util, this is a screenshot from the beta:
