I pulled a lot of info from Anjuna's complete FA20 tuning thread but had to tweak a bit since he had some different mods. Arghx7 had a ton of FA20 technical info and basic guidelines for intake/exhaust advance/retard. Here's a link to screenshots with my current tables. Main thing I'm noticing is it's taking less pedal pressure to maintain speed on inclines during cruise. MPG is improved but I'm not sure on the %.
Could you add the AVCS Exhaust (TGV Closed) table to your screenshots? I think it's missing and I'd like to check it out.

I may try out AVCS timing similar to yours, but it seems a little extreme since you still have TGVs (I'm assuming). From one of Anjuna's threads, I gathered that changing AVCS at low loads was mostly done to make TGV-deleted cars run better. Still something I'm going to mess with a bit more.

I'm going to try out Anjuna's throttle tuning too. Maybe I'll modify it like you have it.

I made a ton of changes over the weekend and I'm pretty happy with the part throttle cruise results in the .39-.91g/rev range. In addition to tweaking AVCS and the TGV switching threshold (potential open a bit later than stock at 65g open/s/61.5g/s close instead of around 60/56.5 for potential open/close and I increased the throttle RPM close/open threshold a bit). I went back to a static throttle target and really like it over the interpolated version I tested last week. I made a tweak to Anjuna's RT -> accelerator position at the 20/30% range to stunt it a bit and I like the change. I mapped the the RT -> acc position to the RT ratio throttle opening (for the most part) and the throttle is snappy but I can see the requested torque increasing fairly gradually over a pretty good portion of the pedal travel so it's not everything at 30, 40 or 50%. The RT/Throttle mapping along with removing a good chunk of 1st gear tip in ignition retard has transformed my driving experience.

Main thing I changed with AVCS was advancing intake more while the TGV is closed and the changes are dramatic after incrementally adding some dynamic ignition over several revisions. The phasing is something like -6,-3,-1,3,6,9,12 intake TGV closed from low load to .91g/rev load range. Exhaust side is 6,6,8,8,10,11,12 in cruise range same load. I was going in circles until I realized the cruise range is mostly TGV closed unless I mash the pedal and/or exceed the airflow switch point. Once I started paying attention to the voltage switch from high to low (TGV right is 3.16 for closed and .78 for open I think). Looking at log stats the MPG is definitely better while TGV is closed which is why I'm trying it out with keeping the TGV closed slightly longer over the stock setting. So far I'm liking it and the car is snappy. With the EGR delete and changes to AVCS it seems like the engine wanted more timing so I started adding ignition timing very gradually and the car started coming alive in areas where it was normally sluggish (2400-2800RPM). I may try incremental changes to exhaust retard but the car feels really good with the advance/advance approach in the cruise range versus the stock retard/retard AVCS settings for intake/exhaust with EGR. I posted some new screenshots but let me know if you want some other tables.

Most recent cruise log with a couple 3rd pulls. I'm still trying to dial in the WG duty cycle in a few areas.

Just looking for some feedback and if there any concerns with this e-tune. Overall it feels great, and the log looks good to my untrained eyes other than a little under target boost.

- 2018 WRX Limited
- COBB resonated catted DP and catback
- 6MT
- Costco 92 octane
- Mikey's e-tune
- 3rd gear

Link doesn't work. Set it to public. I am curious to see the pull since Ron is taking a break from E tuning and see how Mikey compares.

As of a few days ago, Ron started e-tuning again (at least for now).

That is great news! I certainly understand why he needed a break but I am happy to see him back. He is a huge part of the community.

I think the boost looks fine. There are times that I am right on target and sometimes about 1-2 PSI below. Temp changes and other factors come into play. Ill take that over those nasty boost spikes. I rarely spike now and if I see a spike it is only about 1 psi or so, even in extreme heat and this is with stock boost control. Also, probably not the best idea to rev up to 7K.

Definitely! I hope he paces himself though. You could tell he was getting swamped with etunes and basically had zero life outside of work. When I got my dyno tune from him he looked like he hadn't slept in 48 hours.

I've seen tuners setup e-tuning slots, they sell 10 slots at a time and when those tunes are done they open up another 10.

It looks like he got to 7,290 rpm on that log. Why didnít he hit the rev limiter and get the fuel cut? I ask because when I did my etune and was doing a log I took it just past 7k to around 7,100 on accident and it scared the ***** of of me when it happened. Maybe itís completely fine, but I thought the rev limiter was lower than than.

His limiter is set to whatever his tuner decides. But 7300 would seem excessive.

Props to Mikey. He e-tuned my WRX and really brought out a beast, but safely. I would say not to worry about Botti if Ron decides to hang it up. Iíve put my tune here for scrutiny before and got great feedback

Default FA20 COBB Logs - Post Yours Here!

I will add though, you should try and keep the ethanol content as low as you will allow. The stuff really is toxic to these fuel systems. Local Cobb guy not only blames the HPFP, as we all know, but also the cellulose filter in the tank. Says ethanol causes it to gel up, break loose and clog downstream. I put a lot if miles on my car (57k over the last year and just rolled over 100k) so I get to see results sooner. Iíve had to replace my hpfp and in tank. May have to go further as well.

Youíre on a Ron Watson tune, correct? Do you know what yours is set at?

Are you finished with the tune revisions with Botti? I am on R4 (first rev with Ethanol) and I am pretty far below target boost as well. I think hes just keeping it conservative (which I am 100% OK with), but I was far off enough at one point that I thought I had a boost leak.

Just be patient. You're only on revision 4. He'll start dialing up boost and timing soon.

Absolutely! He's the pro, I am most definitely not. Anyways, I posted the wrong log above, the correct one is below.

Can't wait till he really opens this thing up - it's like a whole new car on the E!

Ok, definitely think I have a tiny boost leak now. Thoughts?

I'd say you probably have a boost leak. It can only be a boost leak or wastegate duty that is too low, but your wastegate duty cycle is already pretty high (quite a bit higher than than even Cobb high wastegate maps).

Did a 2-3-4 WOT pull yesterday and registered a -2.81 FBKC. AC was off, DAM remained at 1, no audible noise heard, peak boost (~19 PSI) doesn't seem to indicate a leak and a quick glance at the richest AFR reading (10.30) doesn't seem to indicate I'm running lean either. Unfortunately I wasn't logging at the time, but will try to take one tonight.

2017 WRX
26K miles
TGV deletes
EGR deletes
Grimmspeed EBCS
Grimmspeed TMIC + Charge Pipe
Dyno tuned by Ron on 91

It's a bit surprising to me as I never see more than -1.41 and that's always with the AC on. I'm willing to bet it was either me mashing on the throttle too quickly and not being mindful of how high my manifold temp was (82 degrees out last night and pretty humid), or just transmission noise, as I did hear and feel the tranny move between my hard shifts. Planning to get a Group N mount soon...

One of the problems with these Subaru ECUs that they only compensate ignition timing for intake temperature, not manifold temperature. This means that if the intercooler is heat-soaked, and your manifold temps are high, the ECU won't pull any timing as long as your pre-turbo intake temps are fine.

A 2-3-4 pull is going to heat soak the intercooler while keeping pre-turbo intake temps cool due to high airflow. Knock will be more likely than a single 3rd gear pull that was probably used to tune your engine. I'd certainly do some more pulls to check for fueling accuracy though.

Your car knocked. It happens. Were in the middle of Summer right now and you live in SoCal. This doesn't require more diagnostics for one knock incident.

I'd be more worried if you never are able to get your car to knock at WOT after driving hard in SoCal heat.

My thoughts exactly. Still waiting to hear back from Mikey, but trying to schedule a smoke test in the mean time. Must be a tiny ass leak to only stop boosting at ~19psi.
