Open Flash Tune for NA Catless Setup

[neroman98]

Hi guys, just needed some quick advice!
I'm about to install a catless front pipe on my FRS which would leave me with the following set up:

JDL UEL Catless Headers
ARK Design Catless Front Pipe (2.5in)
Stock Overpipe
ARK Design Dual RacingSpec Catback Exhaust (2.5)

I have an Open Flash Tablet and am running their off the shelf tune for UEL Catless headers right now.

Is there an ideal off the shelf tune for a catless set up or does anyone have tips for how to make my own tune for an ideal catless tune?
I have no real tuning experience but have no problems with messing with the tune to experiment and learn (without blowing up my engine, that is).

Thank You!

OTS stage 2. There really isn't that much to gain with a catless fp from my understanding.

Oft tunes are for xatless header, mods to exhaust after header dont effect the tune required mich at all.

Just check your fueling and adjist maf scaling as necessary to bring commanded afr and afr close

Then check for and knock that causes iam to drop below 1

Too main things that vary a little ars those to fuel formulation and minor differences in maf sensors

Especially if it's a high flow cat in the front pipe. I got on it with my brother in another car behind me and he said it stunk when I did. Must not be very restrictive
