Thanks Trakkies! I got everything working correctly this afternoon I had a short I hadn't noticed.

Im going to go over it all again, I can trace the 9.1 volts a ways through the stim board but keep losing it at a resistor...

Seems like im striking out all over with this project so far. Hopefully I didnt hurt my new ecu.

I bought a second ECU already assembled since im looking to install these on two cars anyways, I cant get anything out of either Im really leaning toward the megastim I assembled, shouldnt it light up when plugging in into the ecu that is plugged into my computer?? Im leaning toward getting a 12v ...

Im not seeing anything across d13, maybe I have something wrong with my stim? Not much to go wrong on it though...

I sent you a pm regarding a second ecu i purchased that was pre-assembled. Hopefully I can get one of the two working and fix the second...

I purchased a diy autotune unit but im having trouble making it run off mstunerstudio or megatune...

I have tested my serial x usb cable using hyper terminal and it loops back

I hooked my ecu to the computer and have the stimulator ...

Unless im missing something I do not see a D10 nor do I see it on the megamanual list. Maybe someone could look over this picture real quick maybe someone who has done this before can see something evident I messed up....

No luck no voltage showing up at all at U5

Thanks for the information I will try that this evening.

I am new to megastim and just assembled my first megastim and ecu ms1 v2.2 board and having issues getting past checking the first checkpoint for powerup. I have my megastim plugged in and checked all of the components to step 19 but I cannot find 5v anywhere on my 40 pin chip socket. Is there a way ...
