Hi guys, I just bought this ECU from Jerry at DIYautotune! Great guy!
Anyways, I needed to mod the board first off so it'd work with my hall sensor.
To do this I:
Cut out caps C12 and C30... , and jumpered D1..
Then I needed to setup the onboard coil driver, I followed the instructions posted on the MS&S-E website to do this...
"Top" of r26 >> 330ohm >> IGBTIN
R57 not fitted
Jump R43
jumped IGBTOUT to IGN
Anyways, I know this is standard stuff, but I took some pictures of the mods I did so you guys can take a gander before I power this up... I'm on a really tight schedual to get this car running so I don't have much window for "oh oh that smells like burnt electrical!"
Thanks in advance guys for a quick once over!
Pete
"Proof read" my board mods please!

you need to do the rest of the mods to get your hall sensor to work. jumper opto-in to +5v, and tachselect to XG1.

Ok i'm gonna confess i'm a little confused what to do with the hall part of things... It seems like there are a few different ways to do this that all work..
On the DIYautotune page, he tells you just to cut out the caps, and jumper the D1... He also mentions a 1k pullup resistor if your signal is weak.
However, he does not mention anything about cutting the XG1-XG2 jumper, or any other stuff like that...
I don't want to end up with half of both ways of doing it because that probably won't work.
can anybody shed some light on this?
