'99 Miata MSPNP Gen2 tune non-boost w/ minor upgrades

Post by Nwar »

1999 Miata tuning file using a MSPNP Gen2 non-pro ECU. Using firmware MS2 3.4.2 and TunerStudio version 3.0.22
List of mods to engine:
*Skunk2 64mm throttle body
*BEGi custom intake manifold w/ 8inch short trumpet runners, ported to TB(used to free up engine bay space, gain accessibility, save weight)
*Phenolic insulation intake gasket 0.25inch
*8.5mm spark wires(oem ignition coils)
*FM 36-2 Trigger wheel used
*ExIntake camshaft mod @ 197.5 degrees
*Rx8 injectors (yellow body) 450cc @ 3bars
*Radium Eng. fuel rail w/ pulse damper
*Radium Eng. Fuel Pressure Reg set @ 3bars(43.5psi)
*RacingBeat 4-1 header, CAT replaced with RacingBeat pipe, 2.5inch exhaust system throughout
*Recent refreshed cylinder head, new valves, springs, solid lifters(SUB), valve seals, and intake/exhaust gasket matched porting @ 25Apr2017

Idles okay. Stable when rad fan kicks on. No A/C, power steering. Decent acceleration after 4000rpm all the way to redline of 7200rpm. Slight hesitation of a quick throttle blip. No issues when shifting. Good cruise mileage, gulps gas when aggressive. 5 minute warm up time due to coolant reroute. Driven in mediate warm climate only.
