PFS purple box vs. stock ecu - which one should I use?
Current engine mods:
M2 intake, hi-flo cat, JIC exhaust, rx7store.net downpipe, Greddy SMIC.
When I bought the car earlier this year, it came with PFS piggyback and a laptop with different map settings. I guess the PFS are also preloaded with default map setting as there is a **** indicating Low, Medium, High. I hooked up the PFS and turned the **** on the Low setting. The car runs good (it ran good with stock ECU but the boost was very choppy) and my boost gauge indicates a really smooth boost curve, nice turbo transition and peaks at 0.8bar. I understand that's a little high but still safe.
Now, I know the PFS is a really old system and I don't have a wideband O2 sensor to fully tune it so I want to know is my car better off with the stock ECU or with the system in? I plan on taking the car to trackdays.
Also, since the PFS came with a laptop and a software to play with all the settings, are there different maps out there where I can download maps to better fit my mods?
Sorry for the long post and thanks for any tips.
