MS build thread
Well I decided to dump this here, if its the wrong place let me know.
Goal is to use it standalone completely. I am trying to find the ecu connector but they seem hard to procure now, anyone have a link to places that sell them?
Bought MS1 pcb 1.01 and stim board unassembled kits
bunch of stuff
stim ready
power part setup

so got the connections circuit hookedup going onwards to the next part.
I was thinking about how maf\turbo would work I was thinking that even though you can't see pressure you can still see air flow which of course should take into account the pressure since normlly you won't hit a certain airflow on the maf without FI there will be a peirod where no matter what rpms eventually the airflow will start to rocket up reporting by the maf just need to find that spot and pretty much say starting adding this much fuel, just my idea of how it would work, can't wait to check it out, don't know if MS tuning software will even let me do that. But we will see.

now to get a variable tps, wire up the fuel pump correctly, and figure out how to pull a trigger signal, lol.

Ok so I got abit of a problem. In Megatune I can see the megasquirt, mess with the controls on the stim and watch them move up and down. But trying to connect my Megasquirt to Megatunix or tunerstudio doesn't happen, neither can find it.
Now Megatune won't work with the megasquirt if I chose any other firmware type than B&G v1 orginal.
So far I think it maybe a board problem as the serial cable is correct straight though and I tried megasquirt connected to 3 different boxes with megatunix on them.
AS we can see here
<djandruczyk> 10 0.00000754 megatune.exe IOCTL_SERIAL_SET_RTS Serial0 SUCCESS
<djandruczyk> 11 0.00000754 megatune.exe IOCTL_SERIAL_SET_DTR Serial0 SUCCESS
<djandruczyk> thats NOT CORRECT
<djandruczyk> MS does NOT use flow control
<djandruczyk> MT should not be seting flow control lines
<hentaixp> just reporting my findings thats all
<djandruczyk> MTX does the correct thing:
<djandruczyk> 17020 0.00000838 megatunix.exe IOCTL_SERIAL_CLR_RTS Serial0 SUCCESS
<djandruczyk> 17021 0.00000922 megatunix.exe IOCTL_SERIAL_CLR_DTR Serial0 SUCCESS
<hentaixp> well its making something work
<djandruczyk> you could try editing winserialio.c and setting it to enable the DSR/DTR flow control lines and see if it works, if it doesn it shows a wiring problem on the board
<hentaixp> wait .c
<djandruczyk> odds are theres a bad solder joint or cable that has pins internally tied togethjer
Now I'll get some high rez pictures of the board later, but if anyone else may have an idea let me know, thanks

I need to find a place to pull 5v from though, not sure if the 470ohm is currently connected correctly to a 5v pin hole

Anyone thats done the IAT mod take a look at this and verify its wired correctly?
