KZGUNS tuning

KZGUNS · Mar 19, 2019

hmmm I guess i could email them @a91what they are both about 30-40 min so lots of good data.

KZGUNS · Mar 19, 2019

I emailed them to you. Maybe you can get them to load here.

a91what · Mar 19, 2019

Nope files too large, you would have to put them in a zip folder.

KZGUNS · Mar 19, 2019

ok lets see if this works. All 4 DL in this zip file.

I will look when I get to a PC.
Now as for the hanging idle on warmup, if the pwm duty goes really high (10 points or more above target) then that is likely the culprit this can be adjusted in the initial values table. Let me double check for you and see what think.

Also need the tune you took the datalogs with.

Hey go over to the NOTES tab to see the list of changes i made

It’s definitely going 10 points or more over. The tune are used during data logs is in my post above

Excellent! Just like that i learned something in ref. to the initial values.
If its dipping too much when throttle is lifted should i slowly add to the dashpot adder to compensate?
I was thinking the changes i was going to make in the ve table were a tad aggressive but i was really close to what you did.

If dipping to much add the PWM% to the initial values table adjust 2-3% at a time notice that the table is relative to the MAT temp vs target idle speed.

Quick update for those following along...
Latest tune fixed the hanging idle during WU. I did bump up the WUE a tad to smooth it out but its running great. Hopefully get some DL in this weekend. Can't thank Steve enough!

Go Steve...He definitely is a GURU in the MS

Wats your plans now for the car, since the tune is going so well

Mostly just drive it this summer. I’ll probably do heads as well. Looking at options now. Then during winter I’m gonna go turbo or supercharger. Leaning supercharger. I’ll also pull the engine and clean and paint the engine bay.

stanglx2002 · Mar 22, 2019

Sounds like awesome plans you have there...I will be keeping an eye on the progress for sure

Quick update...
Been driving a DL when the weather permits. Been tweaking the VE and getting really close (I think ha!) will get some time in this weekend and post up tune and DL. All this tuning has caused a little surge during WUE so I'll get a couple chances this weekend to play with that, its not horrible but I'm sure WUE is getting a little lean in spots causing the surge. Car is feeling really strong and could probably leave it but you know we love to tinker lol

Car need to he richer than target during WUE.. this will keep it happy and quell the surges

Ya that’s what I figured. Gonna bump those numbers up while it’s in WUE till it smooths out. At least now I’m not scratching my head wondering what to do. We’ll have to have another session to look it all over and get you squared away $$. Couldn’t have gotten even close without your help!

a91what · Apr 5, 2019

in a datalog bring up these fields..
AFR
TARGET AFR
FUEL: WUE
AFR ERROR

look at the AFR and target afr in warmup, you want to be .3-.8 richer than target while in WUE. you can see the WUE % and can then adjust the WUE curve to add fuel with a datalog instead of chasing a moving target while the car is running.

KZGUNS · Apr 5, 2019

That makes a lot more sense!!

KZGUNS · Apr 7, 2019

@a91what got WUE pretty good now, one small spot i'll look at again but overall better. here's 2 DL and tune. I feel like i'm going back and forth at this point, making small adjustments and then going back. Obviously there's not a perfect ve table so I'm assuming i'm getting to the end here?

a91what · Apr 7, 2019

Once you get to the point that your within 2-3% your pretty much done man.
