I would say use absolute values that your car, abmbient tmeps andthe quality of gas dictates...

Even absolute values will yield different performance because timing is always changing...generally 17 psi for good quality 93. Mid range ramp down to 15... higer octane maybe 18 ramp down to 16... meth 20 ramp down to 18

No imperial evidence or science. To back this up though ... my opinion hibestky ..
Thats some crazy variations you are seeing on boost, hopefully Terry can provide his thoughts.

Yeah, Im leaning toward sticking with absolute values as well. Any reason for the ramp down? Im at 18 across the board, and looks like boost naturally comes down towards redline. Have you experimented with both?

Also, do you know if map 4 adjusts for increased airflow of **, etc, or is it strictly stock tuning with no adjustments at all by jb4?

I was running e20. Now just straight 93
The temps have changed a lot in the past few days here in NY
It's a lot cooler. I have to reconfigure my map 6 settings.
I will post some logs in a few days.
The boost is over shooting the target in the lower RPm range.

I was having the same issue, try increasing FUA assuming you have ewg wires.

Im interested to see what changes are needed when going from e85 mix to pure 93 oct. Im assuming its just dialing back the boost?

started all over again from scartch with map6
i relogged map 0 to see how the dme is responding to the d0wnpipe,
it seems to be overshooting the boost in the lower rpm range so i redid map 6 with that in mind
map 6 settings:
boost 2000rpm to 4500rpm 15psi
5000-7000rpm 16psi
pid gain 10
fol 80
fua 30
6-cyl timing 70

Your timing is at 0 on almost all cylinders for the entire run. I would be very cautious running the boost you are with no advanced timing... a knock is right around the corner without timing. The dangers of absolute targets..


To tune properly:

Take a base run Map 0... Running 4 or 5 times hard then log
Take a baseline run Map 6 ALL DEFAULTS with the boost ranges you defined. 4 or 5 times hard - then log. At any point the car stutters... stop pushing it hard and try to take a log pushing it hard.

Pushing it when its stuttering will throw a code eventually. Ideally you want no codes - stealership will then know something is being messed around with the next time they read the computer.

Once you have good baselines then start to make changes...

If your impatient:
FUA 30 - is pretty high... I would start with 10 and increase until your throttle closures are reduced. You're leaving power on the table..

FoL at 80 your lucky your not getting a codes - I would reduce it back to default 60 and see where your at.. the idea is to keep Trims below 50... your in the 20s.. if your still below 50 set it to 0 - FF wires probably not needed. OR put 2 gallons of E85 in there.. You have room in your trims and afr (though your AFR is a little higher then I would expect for trims being so low).

6 CylTiming - put this back to stock (0) and see if there is a benefit to timing by decreasing IAT. I doubt it will make much of a difference unless you're in arizona or something that is 95+ degrees out. No sense messing with something that yields no benefit - and clearly its not.

I would definitely put everything back to the default settings before moving forward. Your Map 6 log actually looks fine, but your Map 0 log was absolutely horrible. That means that you are starting with a lot of bad settings, but somehow got things to work with Map 6.

You should be able to switch between Map 0, 4, and 6 at any time without too much difference in throttle, timing, and AFR. Post up a few Map 0 logs (i.e. do multiple pulls to let the DME adapt properly like Risktaker said) and we'll go from there.

Thanks for all the good info.
I'm gonna reset ECU
Run map 0 for a while datalog and I'll see where I'm at.
Yea the 0 timing had me thinking. Something isn't right.
I'll post some map 0 logs when ready

I would also like to try map 6 with me.
I come from germany and can thus ultimate 102 octane refueling where map 1-3 runs well.
if I want to go now map6, I give only with user adjustable settings under map6 Boost the psi which he should have to the ecu psi or what he should have a total.
what would you recommend for the beginning?
do I have to change any other settings?
I have no EWG cable.
Performance I would like to drive with ultimate 102 without meth, no more power must be as in map 3, but at least equal.

thanks

Is there anyway to get meth safety settings from map 7 to work on map 6? If not it appears as though all meth/x98 users are basically confined to map 7 unless they want to risk it

i reset ECU, ran map 0 for a few days, pulled a log, then switched to map 1 did a bunch of 3rd gear pulls then logged again, take a look at datalogs, the throttle is partially closed the whole pull both on map 0 and map1,

Do you have the FF wires? Are you running E85?

If yes for the FF wires and NO on E85 then put FOL to 0 and retake the log on map 1..

Map 0 i never has consistent throttle - I believe that is normal.. Though yours a little more then usual - One thing to keep in mind after resetting your ECU it does take some time for it to learn - it could be that also..

Yes I have ff wires. That was straight 93.
I left the fol at 60, but since that log I put in 1.5 gallons of e85 upon fillip.
Gonna relog and repost.

Setting FOL to 60 with 93 octane the car runs like crap... When your on straight 93 set it to 0... when your running E85 and depending on your trims then set it to 60. It doesnt benefit having it set unless your running E85 - this is my own experience.

I run 0 since my local station that had E85 is now closed...

Been logging a lot lately.
Why when using absolute value does wastegate adaptation go down to almost 0

I have EWG wires and when I run absolute targets on Map 6 around 17 PSI, my FF learns down to 1. When I run Map 4 it doesn't seem to move. And when I run Map 7, it seems to change to 20 - 50.

I don't run any additive maps.

Additive maps it doesn’t move
Map 1-3 and additive boost on map6
But
Absolute target map 6 it goes right down to single digits after a few runs

Anyone having issues controlling boost using absolute values with d@wnpipe and the cold weather. Car is boosting past absolute value set point.

Yeah, that's a known issue. Use higher FUA values. You can also step up the boost more gradually. Attaching my recent log for reference. Slower ramp up, with a peak of 18.5 psi.

I’ll give it a try. Post some logs.
What FUA you running
Also did your FF Learn down to 2?
