Hey Bryan, I have a ScanGauge II mounted on the dashboard of my 09 Ralliart and I've been running your 2009 USDM/CADM - 93 oct - GST Boost Pill Upgrade tune since the first day you posted it, and one thing I've noticed is that the A/F ratio is locked on at 14.6 all the time no matter if I'm running the car hard or just doing some normal driving. With the factory stock tune, my A/F ratio used to fluctuate a little(mostly downward) depending on how hard I was driving the car. I've heard that 14.6 is the goal when tuning a car, so I was just wondering if you intentionally tried to shoot for that A/F ratio consistency, or if it's just the unintended positive result of the quality basemap that you created?
And open loop its going to read how much air and boost there is. Then try to keep it rich under boost.

You would need a proper wideband AFR sensor and gauge to see true air/fuel mixture.
Hope this answers your question.

The more I read about this, the more I want to do it to my RA (running 93 octane, looks like I got here at the perfect time).
Sorry, I'm a noob at advanced car stuff, so bear with me.
Is it easy to download the stock basemap from the car, so that I can put it back on later?
Also, my dealership looks pretty legit, so they might be able to check ECU flash history. Wouldn't they only check it in instances where they have to upgrade it, or something of the sort? Not just for regular servicing, right?
Lastly, I'm gonna put in a drop-in air filter (HKS), that won't affect things too much right?
It's a leased car, so I hope there won't be too many problems when I flash. Luckily (or unluckily, depending on how you look at it), all I need is the Tactrix cable.

WOW thanks GST... (Just found this thread and must subscribe) don't have the time to read through all these pages at the moment but not here for the boring my gas is better than your gas comparisons. Can't get a hold of tactrix cable right now but looking to see results on stock RA 93 octane in cold weather (new england)

First, i think this community should have more people like you around that enjoys helping people out. I think the community owe you more then what you owe them. I bet everyone who uses your flash knows that.
Second, related to the quote you said. I think most people who owns a Ralliart would have a cat-back exhaust. And we all will appreciated if you would make a catback basemap. Thanks.
Third i am new to all this ecu flash and everything how do i flash my ecu for an Ur air intake. Thanks. If it is too hard i might just go back to the oem intake please let me know thanks.
