Got a few questions...it's been 16 months since purchase...and looks like I missed place the instruction? and disc.
1. Locate and remove the factory ECU. Carefully release the harness connector's latching mechanism and unplug the harness. Kick the stock ECU to the curb. (OK, better not, might hurt your foot).
2. Plug the MSPNP2 ECU into the factory harness in place of the factory ECU you just removed.
3.Route the included 1/8' vacuum hose through your firewall and connect to the MAP sensor barb on the MSPNP2. Connect the other end to the included 'T' fitting and tee it into the vacuum signal used by your fuel pressure regulator.
4. If using a different size injectors than factory, adjust the REQ_FUEL and other settings for this based on the information in Section Four below.
5.Set your base timing according to the MSPNP's documentation. This is of course, VERY important. You must forget everything you know about setting the base timing on the factory ECU except for where you point the timing light. You MUST use the MSPNP's instructions to properly set your timing. The ECU cannot command proper timing until you synchronize it's commanded timing with the actual timing at the crankshaft. It's easy to do, only stressed here due to importance (and the fact that people tend to try and set it like the factory ECU required, and you're not using the factory ECU anymore).
6.Verify all steps in the vehicle specific installation guide for your vehicle have been followed exactly.
7.Start your engine!

Got the new engine management in. I decided to go with the microsquirt for tuning the new 351. I purchased the complete kit to make install simple.https://www.efisource.com/wp/shop/microsquirt-for-1986-93-ford-5-0-mustang/Thanks for Watching!
