6 ESSENTIAL Tools to SELF TUNE your Subaru 

Also tune your afr gauge that’s permanently mounted to be the same as your tuners readings. Meaning fool around with the 02 sensor location untill they are identical numbers. Otherwise your tunes won’t be in sinc if they are a e tune later on from a log.

The switch is genius. I did this and mounted it next to my obd11 port.

Great advice Duncan from a man that’s been there done it and got a wardrobe full of tee shirts! Great work keep it up 👌👍🙏

Excellent video - I have a WRX STi gc8 with link g4 and learnt tuning off if. Also have an 06 STi, ss V8 l98... Tuning is handy it brings together everything mechanically

Stellar job, Duncan!! Love your videos!! 👍🏾

Wicked job Duncan cheers

Duncan, please make some videos about Haltech's Pro Plugin ECUs...

How accurate is wideband reading from the muffler? Or how much delay is from measuring from there, compared measuring from 5-10" from the turbo? Also is catalytic converter affecting AFR? I mean measured before and after.

What about if im trying to tune a Subaru Crosstreck 2023?

Hi Duncan, can i rely on the factory wideband o2 sensor on my 07 forester xt for tuning/data logging?

The custom knock controller. We used to run a hot wire beer the motor and it picks up any vibration

Youre videos have motivated me to try this out on my fa20dit, any advice on what to read up on, I’ll be using subaruedit

Duncan, if you needed to tune a 22 WRX what tools would you use since it seems the opensource will not work on this generation.

Been throught most of your vids🤟🏾🤓thanks for sharing your knowledge! Travelmate acer spec? Ram, 4 8gb? Chip i3 i5? Screen 13" 15"? Thanks a lot!

Good video. Does your laptop provide a warning when there is danger to the manifold and (relevantly to that - obviously) bits of the floor are about to fall out?

I have a blue open port 2.0 cable that I paid 22 bucks for that works better than tactrix and is way tougher.

Great content, Duncan. I have a Hatch STi. I've been planning on contacting you for a map in the new year. I'm not bothered about making more power. I just want to know it is running safely. Just curious with regards to lambda readings. Mine has a Cobra quad pipe exhaust. Would that affect the lambda readings in any way? Just thinking exhaust gasses would be looking for the path of least resistance and go out of another pipe? (if you catch my drift) Also, on the hatch, is the stock lambda not good enough to at least get a ballpark reading? I run a AEM Electronics X Series OBDII because in a single gauge it can supply loads of useful OBD ECU information. I have it set to AFR and I have seen it go to 10:1 under boost and 20:1 off throttle (when slowing down) Thanks.

Any thing more than windows 10 and you won’t get anything to work. Windows 10 is the best platform for flashing Subaru because all the drivers and everything just works

Don’t ever tune your car without wide band and if your serious tuning the knock plugs are necessity. It will save your ringlands.
