      Having a lot of issues getting my car to fire w/ my mspnp2 after installing my turbo new MS. Any help on the following would be a big help

      I got the MSPNP2 extra w/ the quad spark wired up. I loaded the base map file and burned it onto the MS. I'm having a few issues with getting the car to turn over and I'm hoping you can help me out!

      1) While updating the MS with the new base map, I had the car keyed on for 10 minutes. The IGN 6 coil pack was getting very very warm during that time. Is this cause it was keyed on and not being cycled or is it possibly from mis wiring? Other than enabling the number of coils to "waster spark" on ignition options and wheel decoder menu, is there any other major mods I need to make here?

      2) The fuel injectors I have are 60lb per hour injectors. When trying to start the car and it sounds like its about to kick, the first two injectors closest to the fire wall kept coming out slightly and spraying fuel on the block. Is this because I have the injectors turned up to much? Please double check the attached screenshot showing the info I changed on the base map to work with these injectors. injector specs below.

      3) I have a 80mm throttle bottle with my throttle body, where do I adjust for that on the tuner studio?

      4) I'm not using a boost control solenoid. Just an external wastegate and a boost gauge for monitoring. Can I set the boost limits in the MSPNP2?

      5) anything needed to program for meth injection? didn't think so cause the IAT sensor after it will detect issues if temps get too low.

        This should be its own thread, not in here. Hopefully a mod will move

        1. I don't know enough about quad spark but you could have a wiring issue, or the coil is being grounded. You should check that spark output's going high/going low is set correctly for your setup and dwell settings.

        2. you set them up properly, but likely installed wrong. check to be sure you didn't pinch the o-rings when installing them into the manifold.

        3. You don't need to adjust anything

        4. Yes. Look for boost control -> overboost protection and set it to your desired setting. You likely have a limit of 250kpa (~21psi) if you have a standard MAP sensor.

        5. No, unless you want the meth kit to be triggered from a megasquirt output.
