Standback Tuning

[Laloosh]

Want your tune to look like this



start posting logs and well get it done together.

[phailerider]

i WANT you involved in the tuning process of my car. That log is insane. How consistent is the car with holding those a/fs?

[Laloosh]

steady enough to do 5 logs
I did a pull to 4000, made changes
did a pull to 4500, made changes
to 5000, made changes
5500 made change
redline, made changes

I was going to do one more to add a lil of fuel after 6200 but i was low on gas

So from 3000 to 4000 to 5000 to 6000 nothing changed once it was set

Another thing i figured out, once you nail your tune, you can lean out or richen the entire thing, basically dropping the af line i made up or done with the maf transfer function. Now why would this be good? When it hot as balls out and the car runs a lil richer, lean it out using the maf xfer, when its cold out, and it runs leaner, richen it up using the maf xfer.

How about this, you say you do 3 logs, and tweak the tune in between each right? How about posting each log. Then post the map you started with. Then after each log, you show which changes you made. This'll teach us what you are doing/looking at and changing. Then you have the final log with the final map. Some of us can "reverse engineer" the info to learn what you are doing. Just a thought. I'm still waiting on my PG manifold to come in. That thing is taking forever at the coaters!!

Thanks for taking the time to do this for us.

that looks so good its crazy. i think you used a ruler to draw that afr line though.... lol what where ambient temps when you were logging?

[Laloosh]

in the 60s

[Lex]

Does the SB set target AFRs directly or do you adjust the MAF/RPM map to achieve the desired AFRs?

[Laloosh]

you adjust the maf

I know the ECU makes adjustments based on those conditions - just want to know how well these adjustments work with your scaled Maf.

[Laloosh]

i seem to have no problems. I just started messing with the maf xfers so the car has seen noting but 50-60 degree weather nights. What happens when it gets into the 30s? Ill let you know lol

[oskinosmee]

Aye Chris im sure ur getting pissed at me lol but this is my first time playing with the dashhawk like this, so it was a learning process but i did max it like you said this is about 3k to redline

Perfect, Ill make you up a tune by noon

[Laloosh]

Make your standback look like this and do another datalog to see what we have to adjust.





your car didnt really need much adjusted, it seems to be running pretty spot on, just added a lil timing since im not sure if your meth is working and pulled some fuel up top, added some down low. Nothing drastic, grim on the other hand, lol he needs work

[Grim]

=p lol,do you think its my top mount also thats making me get some shitty konck?

[oskinosmee]

I showed loosh where my meth was tapped its spraying but how can i further tell?
BTW Thanks

[Laloosh]

I dunno if its spraying or not, does your level regulary drop when you get on it?
You said its activated at 19psi, this turbo wont hold 19 psi, maybe try activating it at 15 to be sure

A lot of it is due to heatsoak.

Loosh, do all the adjustment tables in the Standback use TPS for measuring load?

[Laloosh]

thats the way i have it tuned....you can change it maf if you want.

[oskinosmee]

No it comes on at 14 psi

[Laloosh]

ok than thats good. Data log again, if your knock stays kewl then ill start fucking with timing more...that takes feedback from you cause anythign over 3 degrees is a pita to dial in

[oskinosmee]

Hey loosh on the MAF map at 6031 (the table before the -4) is that a -3 or 3?

[Laloosh]

-

Im using that peak shit, i have a gallon of 50/50 mix in the fridge made at IAG in baltimore, but when i was using that i didnt see the temps drop either. WTF

[Laloosh]

i think it depends on which DH version you are using. im using 2.5 beta 7 i think

[oskinosmee]

Alright loosh heres log 2, i got a max of 0.4 knock and boost temps drop when i let off the gas to about 68. I got some hesitation doing the log too.
Boost 12, 1st and 2nd and around 14 the rest.

BTW Thanks for your help

1. did you put my fuel pump in yet?
2. Are you sure you changed everything as shown cause your car is alot richer now, even though we took out fuel. You had to ask me if certain values were negative or not, can you see the tune clearly?

3. change boost temps to fuel pressure on your dh.

i have a feeling you added fuel instead of subtracting it, thus asking too much of whatever pump your running.
Dropping pressure explains the low boost, rich a/f ratio, and stuttering.

[Darksun280]

doesn't he have meth sounds like he's bogging

[Darksun280]

my temp are about 94 now on stock top mount what are your temps at

I put your pump on i will check again.
The 3 tables you showed me didnt say Fuel pressure. I will check again tho.
In first and 2nd gear meth doesnt come on boost is to low.
I can really see your charts well either loosh

[Laloosh]

like i said, it looks liek your dipping into the 9s which makes no sense. Dipping into the 9s in the midrange will cause stuttering cause no fuel pump will catch up.
If your sure you changed the numbers correctly, run your 2nd map (zeroed) and see what the car is doing. Flip the switch to the map i gave you and see if it remains to run like shit.

Better yet, give me the standback version you are running and ill send you a tune.file, all you gotta is upload it. Problem is that if we are running different versions, it might not work. I think i will just call cpe and have them email me all their different versions so i can send files instead of posting pages that are hard to read.

If you want to see the tune i posted for you just right click and save each image and open it up on your computer to make it bigger

[Laloosh]

btw, i posted 4 tables, not 3. The first config page is vital if your going to hit the desired boost levels

[oskinosmee]

Thanks im running v2 im about to do another run now brb

[Laloosh]

there are muliple versions of 1 and 2. Like i said, see what happens with it after you made sure all the numbers are correct. If it still runs like shit, send me your actual standback software to laloosh@optonline.net. I will make a file using your software. All you gotta do is open it and load it

[oskinosmee]

Hmmm how do i do that?
Edit log 3 i had to get off because of an animal i didnt want to hit but i got back on til redline

[Laloosh]

take your standback cd and copy it onto your desktop. Then send me those files

[oskinosmee]

I sent it

[Laloosh]

i should be home in about 45

[Laloosh]

just got your tune. everythign seems correct. As to why your car is doign the exact opposite of what we want it to do. I'm not sure. Try uploading it again just to make sure it was originally uploaded. IF it still acts up, i would seriously check your connections to make sure nothing is backwards. But thats a longshot.

If it still runs liek shit, zero everything out to the way you had it before. I will be there either next weekend or the one after to tune randys car and ill personally take a look at yours just to see wtf is going on.

[oskinosmee]

I did run again and it doesnt hesitate,it runs like the log i just did, it still doesnt boost right when i installed the the standback i did the voltage test and everything came up right.
