The featureset of each model MSPNP may vary a bit. Here's where you'll find the various models and their features...
1990-1993 USDM Mazda Miata w/ manual tranny
MM9093 has also been tested independently by customers in other countries, and is currently in use in the UK, Australia, Germany, Hong Kong, Sweden, and Greece! So long are your 90-93 car is running the 1.6l motor, and ODB1 computer, it appears to be the same worldwide.
Based on the MegaSquirt-I PCBv3.57 running the MS1-Extra firmware. Initial release will be running MS1-Extra firmware version 029v.
All software based features of the MS1-Extra firmware are therefore enabled. This includes:
12x12 fuel and ignition tables, with linear interpolation between the cells giving you PLENTY of resolution
Programmable Rev Limiter
Overboost Protection (configurable of course, default is configured for 152kpa)
Mappable Air/Fuel Ratio Targeting when using a wideband o2 system (optional)
Coolant temp timing advance
Inlet temp timing retard
MAPdot accel/decel enrichment
Overrun fuel cut
Tons of other standard EMS features that aren't worth mentioning here line by line... but it wouldn't be an EMS without them.
2.5bar MAP Sensor (internal) good for up to 21 psi of boost
Wideband O2 Input (we recommend the Innovate Motorsports LC-1)
Extra Features added to the hardware:
Electronic Boost Control
Capable of using the stock clutch switch, alternately you can wire in a push-button if you prefer
Flat Shift (keep your foot floored between shifts, just clutch, shift, and un-clutch. Keeps the revs up high but controlled, and if your turbo'd, helps keep it spoolin'!)
Knock Sensor Input (for use with Knocksense MS external knock box)
Cooling Fan Control
Closed Loop Idle Speed control
AC Control (yes your ECU controlled A/C will continue to function properly)
100% Plug-n-Play option leaving the stock AFM in place, or optionally you can remove the factory AFM/Airbox and pickup a few more ponies-- we've made this unit as flexible as possible. All that's needed to remove the factory AFM is a GM Style IAT Sensor, a short piece of pipe with an 3/8" NPT bung for the sensor, and a cone filter. We have a kit available here to simplify this.
Built for the Plug-n-Player, but with the DIYer at heart-- there are several features built in to the circuit board to allow for modification and expandability, though of course hacking your box will effect your warranty.
Included with the MSPNP EMS will be the tuning cable, software and manual CD, mounting hardware, and vacuum line with 'T' fitting. Everything you'll need to install your MSPNP leaving your AFM in place. If you'd like to remove your AFM we have a couple of kits to help simplify that process as well. These kits as well as the MSPNP EMS are now available for purchase online.
