I am conerting a Toyota 20R engine from the stock asian carb to gmTBI injection
I have most of the parts needed including a 7747 ECM and a 7165 ECM
I have a programer from MCUMALL and can read and program 27SF512 chips
The 7747 ECM has a Moates G2 adapter and 27SF512 chip
The 7165 ECM has had the EPROM removed and replaced with a 27SF512

I am trying to run an ECM off a 12V power supply and get the WINALDL program and interface working
I checked the aldl line on both ECM With a scope and I get 5V DC but no data stream

What has to be hooked up to the ECM to get a data stream from the ALDL wire that wil be recognised by WINALDl ?
When I program the 7747 with the G2 adapter I just put 8000 in the device offset?

Thanks for all the help
Todd
