^^Have you verified this through testing somehow? Slightly inaccurate MAF scaling, or a little oil from a filter on your MAF could easily account for AF Learning swings. I used to see trims of 5-10% with Ron at WOT on pump gas...

Hey everyone.

2018 WRX
Accessport and Invidia R400 (if you consider that a power mod)
6MT
91 Octane
MAPerformance Stage 1 OTS
3rd Gear

Datazap Link

I've had the tune for nearing 3 months now. It's temporary until I can get a dyno tune but it has been solid. Just posting to see what other people thing. I tried to use all the suggested things to datalog. If I need to redo it, let me know!

I did notice a -1.41 FKL value at 5,538 RPM however I believe this could be phantom knock and generally never worried about that. Thanks!

Here's an example of my MAP OTS 91 Tune on 91E0 around 5600 rpm WOT.
Time (sec) AF Correction 1 (%) AF Learning 1 (%) AF Sens 1 Ratio (AFR)
2.974 -5.47 0.78 11.61
2.99 -6.25 0.78 11.51
3.02 -6.25 0.78 11.53
3.035 -6.25 0.78 11.48
3.056 -6.25 0.78 11.52
3.067 -6.25 0.78 11.5
3.096 -6.25 0.78 11.53
3.103 -6.25 0.78 11.52
3.129 -7.03 0.78 11.6
3.144 -7.03 0.78 11.63
3.159 -5.47 0.78 11.6

Here's the same tune on 91E10. Same RPM range. WOT.

Time (sec) AF Correction 1 (%) AF Learning 1 (%) AF Sens 1 Ratio (AFR)
5.186 -3.91 1.56 10.93
5.198 -3.91 1.56 11
5.22 -3.91 1.56 11
5.242 -3.91 1.56 11.04
5.254 -3.91 1.56 11.05
5.266 -4.69 1.56 11.16
5.288 -4.69 1.56 11.16
5.301 -4.69 1.56 11.15
5.323 -3.91 1.56 11.23
5.335 -3.91 1.56 11.22
5.347 -3.91 1.56 11.19

You can see it pulling additional fuel on the E0 (was very close to E0, probably E1-2 based on very low tank and filled with E0) as the AFR for E0 is 14.7 and the AFR for E10 is 14.1. Since the tune is set up for E10, it has to compensate for the E0. Both are FTCL.

Moving to E30, this was my very first log, before we dialed it in. Ron looked at it and saw I was low on Ethanol (it is pulling fuel and so the mix is too gas heavy). This led to adding 2 more gallons E70 to the mix (on a full tank). I should not that this log did not show any FBK, FKL, Dam Drops or even a single hit of cylinder roughness, so there is some safety net in the tune.

Time (sec) AF Correction 1 (%) AF Learning 1 (%) AF Sens 1 Ratio (AFR)
8.363 -15.62 0 10.73
8.388 -15.62 0 10.8
8.413 -14.84 0 10.77
8.428 -14.84 0 10.75
8.46 -15.62 0 10.71
8.473 -15.62 0 10.69
8.495 -15.62 0 10.68
8.52 -15.62 0 10.75
8.534 -15.62 0 10.73


Based on these, I target +2-4 on AFR Learning+AFR correction. I also have the option of pulling a sample from the tank with a piece of tubing and my graduated cylinder.

I still get the occasional cruise knock (though very seldom) and A/C will pop a -1.41 consistently.

I usually log one pull after filling back up and look for any knock or roughness and then call it good. This works for me as I only drive ~500 miles a month and so I am only filling up every couple to 3 weeks.

From a recent log at WOT, with a good eth mix:
Time (sec) AF Correction 1 (%) AF Learning 1 (%) AF Sens 1 Ratio (AFR)
7.203 0 0 10.98
7.21 0 0 11.02
7.221 0.78 0.78 11.13
7.242 0.78 0.78 11.18
7.257 1.56 0.78 11.01
7.293 1.56 0.78 10.81
7.306 -0.78 0.78 10.73
7.332 -0.78 0.78 10.83
7.346 -0.78 0.78 10.97
7.368 -0.78 0.78 11
7.399 0 0.78 10.95

It should be noted that an AFR of 14.7 on the AP is not 14.7. Since we are using a lambda sensor, it is looking for stoichiometric fuel burn (and how far from that your are). As listed above, that is around 14.1 for E10, 14.7 for E0, and E30 is closer to 13.

WOT log from a few days ago, 3rd gear pull. Does the boost fluctuation look right, especially towards the end?

Intake temps dictate the boost targets. Your intake temp fluctuated a little towards the upper RPMs. Everything looks normal.

So, I have a little different problem, ever since after getting Dyno tune I have been experiencing light jerking under 25-30% throttle acceleration mostly in 2nd/3rd gear between 1.5k-3k RPM.I think it is more pronounced while going uphill I ran both MAP stage 1 prior to any mods Cobb Stage 2 OTS with just j pipe and never experienced anything like this. I just emailed the shop where I had it tuned but I figured I get second opining since they are currently closed and wont be open till Monday. Please let me know if there is anything else you need to know.

Thanks

I was driving down a parking garage and saw my feedback knock drop to a -9 and -7. I did a 5 min log right after (half city and half highway driving) to see if I could catch it again. My log shows it drop to a -1.41 so Iím wondering if itís a false knock, fuel trim or something else??

Thanks

You would know if a -7 or -9 reading was true knock. There are many instances of false crazy knock readings and the -1.41 is nothing to be concerned about. Enjoy the car

What Adam said. I've seen a -8.44 value before just cruising. Nothing to worry about, just your car testing you.

That is a dyno tuning issue. Youíre going in a load range where the car didnít hit on the dyno and something is a little off. Send the tuner a log of it happening and they ought to be able to clean it up for you.

-2nd-4th gear (bit of 5th at the end)
https://datazap.me/u/weslxa/2nd-5th?...ta=4-6-7-13-20

I'm still new to this, so I'm struggling to decrypt what some of these monitors mean and what normal ranges are, so any insight would be much appreciated. I didn't know an intake was a dumb choice at the time (now I know better and wish I had spent the money elsewhere).

Anyways - no clue what normal Commanded Fuel Map and Final should be at during some pulls like this. Also, seems like the AFR fluctuates quite a bit - from what I've read it seems like it could be attributed to the intake, but would love some confirmation that I'm not ruining my car.

I plan on eventually going full turbo-back exhaust, EGR/TGV deletes, and pro-tune, but money's a little tight, so those will come in time.

-1st-3rd gear
https://datazap.me/u/weslxa/clutch-o...0&data=4-13-20

Was just getting some weird FKL on this one. Seemed to trigger everytime I let the clutch out. Happened one other time a few weeks ago. Only 2 times I've seen that since I've had the car.

Thanks

I'm posting this because I feel like my car is the same or slower than before I flashed the tune (power wise). I am feeling the benefits of the better throttle and the lack of rev hang is making my shifts feel nicer just as advertised but the car just feels the same or possibly slower. The guys at MAP have been very responsive to my concerns and have even sent me a second tune. The first one was v3.75 -- FRN, the second one was v3.75 -- FRH. I don't feel any difference between the two. The log above is from the FRH tune. Since so many people seem to love this tune I'm starting to think something may be wrong with my car. I'm also open to the possibility that my expectations were set too high. If anyone can help shed some light on this it would be greatly appreciated.

Do a back to back 3rd gear pull from 2-6.5k rpm. One an old tune/stock and the other on the new tune. Import the log into Virtual Dyno. You'll need to download the software. Configure the parameters to suite your car. Compare the dyno numbers. Keep in mind your numbers will vary depending on ambit temp, humidity, altitude, what you had for lunch, etc, but will give you a ballpark idea. It's free, so you can't really complain.

More accurate way to measure is to go to a local dyno and compare your numbers with other WRXs that have dynoed at that shop. Generally dynos are $75-100 for 3 pulls.

Final option is to pay $300-400 for a protune. Can't guarantee it'll pull a lot harder than MAP though.

Might be that the stock tune gives a burst with very little throttle. If you get on it you should feel a difference with the MAP tune.

Have you run other tunes or is this your first.

Also the stock tune dies at like 4500.

What he said^. Stock tune punches you in the face with tq and then falls off hard. 30% throttle is 100% tq at certain rpms. Cobbs/Maps tune are faster it just doesn't feel like it at first.

I haven't run other tunes aside from the 2 MAP has provided me. I should put the stage1 COBB tune on there to see if its any different.

I definitely had the same thought about the "punch" of TQ that the factory tune had and maybe I was just missing that. But even when I'm WOT it just feels the same or less than I had before.

Even with the cold weather (30-40f) the boost pressure seems low to me. It's my understanding that this tune aims for a peek just over 21psi and then levels off to about 19psi plus or minus a few. My numbers are nowhere near that. Am I under estimating how much the cold is affecting me? Could it be a boost leak?

here is the link to my log again https://datazap.me/u/lynchtastic/map...og=0&data=6-26

I know the car will definitely have lower boost in colder temps. What numbers are you seeing?

its peeking at 17psi then it drops to mid 12s where it then slowly declines til I shift.

You're no where near target boost. Your boost is tapering a lot after you hit 17psi. What is MAP saying? I didn't know MAP did protunes. I thought they did only off-the-shelf tunes?

Flash a Cobb tune and do just a 3rd gear 2-6.5k rpm log.

Itís not a pro tune, this is their OTS stage 1 tune. I think the second one they sent was a high wastegate version of the same tune (not confirmed). They think there may be a boost leak. Iíll flash the Cobb tune and get some 3rd gear logs. I woke up to a few inches of snow this morning so I wasnít able to do anything with it today. Thanks again to everyone who has taken some time to take a look and offer their thoughts.
