Well I'm about to pull the trigger and get me the DIY MSII and I just wanted to make sure I'm not missing anything. Planning on running an MBC so I don't need any EBC bs and I want to do the AFM/MAF delete. From what I read I need these parts for a 'boomslang' configuration( excluding wires and **** ):

-MSII kit ( obviously )
-IAT kit for AFM/MAF removal ( which kit? GM open element sensor or closed element CLT/IAT sensor. )
-PCBv3 and v2.2 -- Pullup Resistors 'ModKit' ( not sure what necessary mods I need this for, if even essential at all. From what I read I think it is for the tach signal input and spark output mod. )

Also, pretty sure I don't need a MAP sensor because the kit already comes with one.

Does this all sound right?

 

The kit does come with a MAP sensor.

You'll definitely want the open element version of the IAT sensor, particularly on a turbo car. It responds a lot faster.

 

I ordered:
1 x PCBv3 and v2.2 -- Pullup Resistors 'ModKit' (mk-pullup) = $1.60
1 x PCBv3 and v2.2 -- Relay Control 'ModKit' (VTEC, TVIS, Fans (mk-RelayCtrl) = $5.00
1 x PCBv3 -- PWM IAC Valve Control (TIP120) 'Mod-Kit' (mk-PWMIAC) = $7.00
1 x MSPNP IAT Sensor Kit - Steel Bung (MSPNP_IAT-S) = $29.00
1 x MegaSquirt Wiring Bundle - 23" Long (SM-WireBund) = $12.00
1 x MegaSquirt-II Engine Management System w/PCB3 - UnAssembled Kit (MS230-K) = $247.00
1 x MPX4250 2.5 Bar MAP Sensor (MPX4250AP) = $28.00
1 x JimStim v1.4 MegaSquirt Stimulator w/ Wheel Simulator -Unassembl (jimstim-k) = $59.00

Should have ordered 2 relay control modkits though. One for the fan and a 2nd one to activate Vics.
If you order a JimStim, it's also a good idea to get a 10 pack of jumpers. The 3 that are in the kit are not enough. I just cut some speaker and led wires out of an old pc. Same connectors, only in pairs.
I'm not using boost control so nothing in my list about that.
The extra map sensor is because I wanted barometric correction.

 

Alright thanks. Thankfully it looks like I'm not missing anything. Should be a hoot to put together.
