help with megasquirt ignition

[kongo]

planning on building a megasquirt II ecu. woundering if this the diagram everone else us or is their something different.
MS2-Extra Neon-420a Manual
Im planning on building it soon try to get some info before hand. looked on 2gnt, an found info on the first chip and v3 board.

The diagram is mostly correct, though it's more common to use a 1k5 resistor for R12 rather than a 470R resistor.

You're going to want to do something like this for spark control:

MS2-Extra Ignition Hardware Manual

MS-I is on its way out, as is MegaTune. MS-II and TunerStudioMS are the new de facto standards. The v3.0 board is still the only way to go.

What else do you want to know?

As always ## a big help. Is it a good idea to do this mod as i build? r should i follow build direction and the go back and do mods.

 

[VelocitàPaola]

If it's your first time building a Megasquirt ECU it might be easier to follow the directions in the MegaManual and then make any necessary modifications. As you can see, they're not difficult, so it won't add much more time.

will i need to mod the stim for this setup? an is the mk-bip373 any better?

 

[VelocitàPaola]

The standard stim can't create the 420A crank signal, only a JimStim can.

The Bosch BIP373 is the standard ignitor. VB921's are prone to overheating and catastrophically failing; they're also hard to find.

I wish I would have know that in advance. just finish putting together a 2.21 stim. is their a ### to test a stim to see if i build it correct? last does my soldering look ok to u?

Well, you can still use it to test the ECU. You can test whether or not the ECU powers up, and the CLT, MAT, O2, and TPS sensor inputs.

is their a ### to test a stim to see if i build it correct?

You want a stim for your stim?

It's not a complicated board, so you probably assembled it correctly. Just go over the instructions and double check the things like diodes/LED's, IC's, and transistors; all the things that need to go in a certain way.

last does my soldering look ok to u?

It's hard to tell in the first picture. The third picture looks okay, but I'd probably use more solder on the DB37 pins.
