Misc Info
The car makes best power with the PM7 ECU which is the JDM OEM ZC ECU. The fuel mapping is much more aggressive than the PM6(USDM Si) and has a higher fuel cut(7800rpm rather than 7000RPM).
It's sweet spot is 5000rpm all the way up to 7500rpm... it has VERY good power up there(wayyy better than 4age high comp). once it gets to that rpm range, that thing pulls like a mad demon. but there are things to watch out for!! the aluminum block is WEAK! well duh...it's aluminum and doesnt like heat too much.
