I have 1500 miles with E30 and CVT is doing well. Granted I’m not autocrossing the car. I’m just driving it docilely as a family wagon :)

I did have to teach some kids in a 2500 Chevy Duramax what a Subaru can do.

Update: The other day I was putting around town (maybe 30% throttle) and my OBW bogged as if it cut timing. I logged a session and noticed I was running lean on Map 2 (93+) at 13-14 AFR under WOT. This has changed - not sure if due to colder ambient temps.

I contacted Terry over at Burger with my logs and he told me to set Fuel Open Loop to 30. My AFR is now low 11’s under WOT which is much better.
Shortly after an on-ramp I was rolling off the throttle and it did it again - bogged down - so I contacted Terry with another log. This time he instructed me to set all Fuel Biases to 80%. This was last night, I have not had a chance to test this yet but thought I’d share my info with the group.

Terry’s support has been great with him always responding within 1-2 hours. Anyone else have to get into custom parameters yet?

I’ve been running the JB4 E30 map3 for 2000 miles. I was in between running errands yesterday and in the middle I started up the car and a CEL popped. It turns out to be P003A. I cleared the code with the JB4 however I was able to get only 1 psi boost from the turbo. The car runs fine just with zero boost. There are no weird noises or smoking from the exhaust so it isn’t a mechanical issue from the turbo.

someone from Reddit has had the same issue on a WRX with the JB4 https://www.reddit.com/r/2022wrx/comments/y7ztz2
My plan is to disconnect the JB4 and see if the car returns to normal. I stand by my morals that when you mod the car, you take the risks if something goes wrong that could be caused by the modification. I’m having my local independent Subaru shop look at it next week. I will not go through the dealer and not uninstall the JB4 and deceive them thinking it’s stock.

I haven’t had any electrical or mechanical problems with OEM Subaru turbos. Not on my stage 2 STI (5,000 miles) back in the day or my 400whp WRX on E85 (50,000 miles). Those were Cobb tuned. I think the problem I’m experiencing right now is likely electrical possible from the EWG connection.

Took the car to Subaru today and they said there is no ECM update/reflash at the moment for them to do. I already ordered a new OEM turbo. Replacing the turbo seemed to have fixed this person’s P003A. Check engine, x-mode on, safety features off

the old OEM turbo with only 4000 miles I’ll keep. I’ll eventually send it off to SoCal Porting from them to upgrade to a billet wheel and fix whatever is broken. Eventually Cobb will release protuning ability for this car and I’ll swap the upgraded turbo on :)
