    I get nothing on cel. When I set up com4 aldl cable checked good. Checked wire from ALDL connector to ecm, they are correct. When I burn chip Flash n Burn says it is good. Maybe ECM bad?

    Can you try a stock chip just to check that you can read data?

    I will try that in the morning. The only thing that I can tell that happens when I turn the key on is the fuel pump relay comes in for a few seconds.

    Changed com4 to com3. Now I can connect and read data with stock AMUR chip. I have tried two 27sf512 chips using AMUR and ASDU bin files and cannot connect/read either one. Would not think two bad chips. Checked offsets when I burned chips, they were correct. Any ideas? Bad solder job?

    Ya, either the chip is programmed wrong or there is a problem between the chip and the ECM board.

    Generally when loading a binary file to program a chip with there is a setting for filling blank areas and it can be 00x or FFx. I don't know which one you should set it to, but I can say that the wrong one doesn't work.

    Got it figured out with the help of Dave at Moates. Had a small soldering error that made six pins common on the G2 adapter not five. Thank you to Dave at Moates, what great customer support!!

    I am using an .adx file (7747 ecm) that Eaglemark has added several patches to. One of the patches are a few dashboards he has put together. As I look at the values for the AutoProm 1 WB AFR in the ADX editor it appears that it uses 0-5v. Would it be able to use the 0-5v (white and blue wire) from my AEM Uego WBO2? Should this be posted in TunerPro Tuning Talk?
