Megasquirt Zeal/Aaron Cake MS2 Question

Zeal/Aaron Cake MS2 Question
I purchased the MS2 v3 and zeal daughter card from diyautotune, I assembled the zeal before I even looked at the v3 board(as I wanted to refresh my solder skills on a $20 board first). Now Im curious as to weather or not I can still run the zeal card if I am following Aaron's ms2 write-up(as he built a second conditioner in the proto area).
Do I use DIY's suggested zeal connections or will they not work with Aaron's megasquirt mod's. I know everyone says stick with DIY or Aaron Cake, dont mix them, but I over looked this part as I bought everything from DIY to make life easier.
Any help is appreciated, thanks you.

Basically what he said. Mentally replace the 2nd VR circuit with the Zeal card and connect it's I/O to the 'Squirt board and DB37 instead. Also I think the Zeal has some generic outputs so you can probably skip adding the transistor for the e-fan, and it has an idle transistor so you don't have to perform the idle mod.
Mixing writeups is OK as long as you keep things consistent and remember what you've done.

So I asked that question too soon...
On step 55(testing sensors) I plugged the stim and my Squirt started its clock cycle on tuner studio(rpms bounce 0 to 8000 with the clock cycle) but it had no response to the pots. Google yielded a guy who had the same issue on bimmerforums(sloved be a trigger wheel config). I was checking over my work on the board and R4 and R7 were hot. I turned the IAT/CLT pots up to pull current away from them(seemed logical at that moment) and they did cool down, but I am stuck with no real time response from the pots on tuner studio.
Am I missing something?

R4 and R7 go directly from 5V to the IAT/CLT sensor, so I don't see a reason for them to be hot unless there is a problem with you stim shorting them directly to ground, or perhaps a solder bridge with some adjacent pads.

Omg, so I accidentally put the wrong resistors in for r4 and r7... I checked everything else and those were the only ones I goofed. That problem is solved.
As for tuner studio not responding, I had to change something from 255 to 2(for ms2). Goes to show when your having trouble it pays to step back from your work. I must have been getting used to being spoon fed from the mega manual and Aarons writeup... sorry guys haha.
