Thanks Fordem and Zuki1018,
The DIY pnp is using the miccrosquirt on the ms2 Extra setup so it is a little different than yours. I have tried all but one other way they show to hook it up. I got it to run crappy and I just shut it off. I'm using the white 0-5 volt for input on option+ and have had the brown wire is unhooked right now. Do I hook that up to tach out on my ms? There are VR-/ VR+ , VR2, Opt+/Opt-. There is a tach out, would I hook up the brown to tach out! I checked it and it has 10 volts.
I'm pulling my hair out! Do you have a ground on the computer board other than through the plug? I'm just using grounds the factory harness uses.

Zuki 1018,
What tuning program and settings are you using for your ignition? I see the rising and falling edge, going low(normal) going high, inverted etc..
I will go over your parameters. Mine does say on the dash of tuner studio it isn't synced!

Im not familiar with the differences of my MS and yours.  Does it already have a wheel decoder and/or a second wheel setting for you based on the G16 engine?

VR and Opt are different types of inputs.  Opt is an optical sensor which you can eliminate as the G16 has only a hall and or VR.  Pin 6 on the dizzy plug should be the tach signal as discussed.

Yes grounds are SUPER important.  I have multiple separate ground locations including some to battery, block, and chassis. Factory grounds should be okay since that seems what the PNP suggests.

Do you have any communications working?  ...water or air temps showing up?... does your TPS show accurate when you move the throttle?  Our ignition setup will be different.  I am using 1 wheel with wheel decoder settings.

You are waaaay better off posting on the Megasquirt forums if haven't already.  Attaching the FSM wire pin-outs for the dizzy over there will yield a lot more specific answers.

I have all communications but ignition. In the TS for diypnp they said to do the setup I'm trying now. 5 v signal from hall and opt ground with a jumper. The brown from noise filter isn't hooked up. The white is B3 and going to Opt + which is for optical or hall sensor in distributor. Here is diagram I'm using. Thanks. Not familiar with Suzuki I've at ms but they give ignition option of swift and vitara already down loaded.

When you say ignition, its hard to follow you exactly because you have the INPUT from the engine to MS.  Then you have the OUTPUT from MS back to the dizzy.  Im not sure which one your not getting wired correct. 

You need to confirm your SPARK INPUT is right before you try cranking the engine... which will confirm your OUTPUT is correct.

SPARK INPUT is tested by the crank/trigger log tool in megatune while cranking (fuel injector fuse pulled so it doesn't try to start).
Once MS knows where your engine is in timing, then you can test a spark plug with a timing light.  You need to test with timing light to confirm MS reads actual crank timing ...before you try to start the engine with fuel pump fuse back in.

Do you have an external coil on that engine?

Ok, I'm using tuner studio so would I us the trigger wizard? It is external coil. Can you tell me what the pink wire does that is going A5 to fuel pump relay? Thank you very much!

It is external coil.

OOH... i have the internal coil.  I dunno how much i can help!

You have helped already! I'm unsure of the fuel pump relay pink wire, is that for 5v?

Can you tell me what the pink wire does that is going A5 to fuel pump relay? Thank you very much!

Looks like what activates the circuit/gate to me just looking at the diagram.

My initial guess is PIN 37 on MS to the fuel pump relay.

Thank you for you help! It was a jumper wire! It runs now just need to tune it! So I can load your file to mine? I might do that I have it on auto tune. Did you delete your idle air controller?

Awesome! ...congrats.

I would load the file, but not burn/load it to MS.  Open it and go to the fuel and spark tables and export them.  Then go back and open your file and import them.  This way it will not change everything... only the 2 tables.

FYI i have the stock injectors, stock fuel pressure and the T25 turbo also.  You should have a very decent tune using my 2 tables.  I may suggest backing off the timing table to start with before you go max throttle/boost... just in case something is different somewhere.

Second to that method, you could load my entire file, then go back and change your code based/output stuff to reflect your setup.  Remember I am using the wheel decoder option... yours is probably distributor.

Yeah i removed the idle air.  Then next problem you may have is heat soaked IAT sensor with megasquirt.  Again... you can always load my entire file which i have "tweaked" this issue to some degree.  I eventually ended up relocating my IAT to the front bumper.  MS1 is not as fancy dealing with this problem.

Ok, I will probably do that then, load your table or load all and modify the ignition. It isn't running to good but haven't had much time to do it, your tables will help that. I have no experience with this so it will be a long learning curve. The mega log viewer is really neat and I'm looking forward to using it! Thanks again, I will take your advice and I appreciate your help!
