I am going to be running this set up on a 96 GT

MSPNP 2
IGN-6 Coil Pack
Quad Spark
98 626 harmonic balancer
OBD-I to OBD-II wiring harness adapter to accept mspnp made by Pile_of_rd1.

Am I missing anything to get this going? I know the first four items are for 93-95 probes.

I am needing to leave the world of unreliability and have a car that will have fewer probelums

You will need MSD 8849 (or similar) to modify your ignition wires to accept the coil pack. Also make sure your settings are correct in MS. And also don't forget to use a timing light to find 10 degrees, as per MS instructions.

Good points. I have a timing light.

Will the disty block off plate have to be fabbed or do they make a block off plate?

[ChillinZX]

klg4-12-603, and make your own mounting braket. I just took a piece of scrap aluminum bent it 90 degrees and drilled holes in them.

Diyauto also suggested using the GM map sensor. Part number GM3bar-map. Now they wanted me to use MicroSqrt3. If I use the DIYPNP2 do I need the map sensor?

[ChillinZX]

No. Per MSPNP instructions, the computer itself has a built-in MAP sensor. You tee it off at the fuel pressure regulator and run the vacuum tubing to the computer.

Do you know anyone running MSPNP with the OBD-I to OBD-II adapter with this quad spark style setup?

B-Ball,

I've been running the DIYPNP for a few good years now. If you want to use the GM IAT, you can. I would highly recommend it, especially if you're going to run some boost. It's pretty sturdy. However, the oem KL VAF has the pins for getting a reliable IAT reading (pins 3 & 5 if looking at the VAF connector).

The 36-1 harmonic balancer from KLG4 is perfect for converting to wasted spark. Use your stock Probe GT crank position sensor. It is a VR type and works fine. Just make sure you set the settings properly in TunerStudio decoder wheel/trigger wheel settings.

Don't stress it: as long as you convert OBDII to OBDI via the harness, you'll be fine.

here are my settings for the ignition settings while using the stock PGT crank position sensor and the KLG4 crank pulley with 36-1 teeth. Be advised, yours might be a bit different, especially if you're using the QuadSpark. ( Also, just follow the step by step directions here: http://www.megasquirtpnp.com/docs/ms....php?isModel=1 )

Thanks for the info. My fear is the whole 96 obd II jargon. I am down here in Fort Walton Beach, so not that far from you.

Do you need to use the QuadSpark? Or is there a way to setup the BIP373 kit from DIYAUTO with the MSPNP wasted spark setup?

[yellow2point0]

If you're using the MSPNP, yes, quadspark is the way to go. I'm a DIYPNP guy who assembled the Microsquirt-based system to my specs to fit my requirements. MSPNP is an already assembled system. Quadspark is much easier and convenient for your case, mjohnson

How would I set timing if I am using quardspark and ign6 coil packs?

upon more reading I found what is wasted spark. Is that how the timing is set so I won't have a disty or cam sensor to turn to set timing? I am used to working on old v8 motors with carbs. This world of fuel injection is a whole new animal.

[Matt Cramer]

You would still put the timing light on the wire to the #1 sensor. You just change the tooth #1 angle in TunerStudio to move the timing.

[ChillinZX]

Instead of turning the distributor, you would type in what you want it at, and change the offset to read it correctly.

I have installed the unit with quad spark ignitor, ign6 coil packs, 36-1 toothed pulley, and OBDII to OBD I harness adaptor to make my stock wiring pnp with the ms2pnp unit. This car is a 96GT. Current list of obstacles are as followes; only four cylinders are firing, the AEM wideband is only reading full lean with the three --- on the display then bounces around and reboots.

I have chatted with Darren (king6fab), he suggests checking the voltage for each set of coils and cutting the distributor wire at the ECU.

My thought is maybe the OBD II to OBDI harness may be causing some issues, has anyone else ran this same setup before?

The harness was build by Scott D.
