flash back your stock rom with oft ( just to be sure you will have no issues at dealer), drive till cel code or problem re appears (reflash resets ecu and cel codes) then take to dealer, possible fuel pump issue , unless your running out of fuel .

car will go into limp home mode with that cel reduced power and 4500 rpm limit.

I know this is off topic with the OFT discussion. So I drove my car to the dealership and they "fixed" my P0193 code. They said my oil level was low that's why my cam positioning wasn't reading my car properly. Anyways, 2 weeks after that "fix" my car is getting my P0193 problem. Its on stock tune and my rpm keeps jumping up and down between 1k-2k rpm constantly. I'm here waiting outside for a tow truck. Been 1.5 hours now and Dealerships are closed on Sundays. Gotta call in late tomorrow just to bring it to the dealership. Any advice?

Something not right here

1.P0193 is fuel rail pressure problem nothing to do with oil or cam position actuators or sensors

Either you or dealer have got code wrong.

2. If you oil level was that low to be causing the cam position problem then you have other serious issues like why was oil that low that oil pressure was dropping. You either burning or leaking oil. If oil pressure and level was that low for any apreciable period its likely caused other damage.

Hopefully the dealer is full of BS and the actual problem is a fuel pressure issue.

Does this also apply to gaskets that are composed of only multiple layers of thin metal?

most gaskets , crush washers are single use, you might get away with it but seldom worth the risk for such cheap components.

I know for sure the first time my oil level wasn't low enough for my car to stop working.
I told them how I asked around and googled what could cause the P0193 and they didn't even look at the fuel pump. They were so set that it was my oil level. Lol.

Quick question, do the included Stage 2 tunes have the reduced idle rpm fix?

all OFT tune's idle is 750rpm stock idle is 650rpm from memory

I mean the ignition idle, when you first turn on the car and it idles high to warm the cats.

You'll have to do that yourself.
It's pretty simple though.

They did reduce cold start idle to 1400 rpm from 1700 rpm,

but you can also adjust the post start ignition timing from -15 to -4 but on usa rom you will also need to disable P050B cold start ignition performance.

see Tune Tweaks link below.

Good info, thanks for the quick reply

Noob here. I just flashed stage 2 uel 91 on my frs. Running Ofh, nameless fo/op and zeta catback with injen intake. I was wondering what kind of range I should be seeing for short term and long term trims if it is running properly? Sorry if this has been answered, but I'm kinda lost and would greatly appreciate knowing how to read the diagnostics

Fuel trims should generally be less than 10%.
