Set the baud rate to 4800 within the WinALDL program.What do I need to do to use the winALDL program with ALDU1? This switch position makes doing so simple and convenient when a PC is not available. Most GM ECMs dump trouble codes when pins A and B are shorted. The bottom most position shorts the connection (0 ohms). Cars that require 10k to connect can be switched to this position after connection. Most cars can be datalogged in this position. The middle position opens the connection between A and B (infinite resistance). Some ECMs require this 10k resistance in order to connect to the ALDL datastream (some 1227165 are an example).
The topmost position places 10k ohms between the pins. The switch on the back of the ALDU1 changes the resistance between pins A and B on the ALDL interface cable. – Under TunerPro ALDL/Datalogging section, make sure you have the correct *.ads file selected. – Under TunerPro Tools/Preferences, make sure you have it set up as a ‘Max232/etc’ on the corresponding COM port. – Under Windows Control Panel, make sure you have the USB/Serial device set up to COM3 or COM4. When working with the 730, have it in the middle position. When using it to connect to the 165, make sure the vertical switch (as you look at it to the right) is in the ‘up’ position. I am using ALDU1 and CABL1 and I cannot get my PC or Laptop to connect to my ecm. Key thing though is that to reprogram a chip, you’ll need to use a Flash chip like the C1, and you’ll want to use a G2 adapter to make fitment easy. Then you can read the ‘stock’ chip using the Burn1. Worst case, you can cut the plastic support piece along the back of the chip, and it will come apart much easier. Squeeze it gently from the sides, and then use like a jeweler’s screwdriver to lift the legs away from the sides of the holder a little bit. The chip you’re looking at comes out of that little plastic holder. They’re pretty easy to install, or I can do it for you. Most folks use an S2 socket snapped into it along with the C1 chip. Just get you a free trial version of TTS DataMaster and then get you a copy of TunerCat with the proper definition.ĭo I need an adapter to get the chip to fit in my TBI ECM?įor chip swaps on your TBI computer, you’ll probably want to use the G2 adapter. You can use the ALDU1 and CABL2 together for both datalogging and reprogramming.
