Speed Density Help
you should be using the 3d ve map made by Roadspike for full resolution and control over your SD tune, so you can adjust the VE in the troubled areas and smoothen it out.
before on 2d tables the only other ways to adjusting was either MAF comp or forced open loop and adjusting problem area.
Roadspike has filled my head full of knowledge.

Perhaps I should try a different rom?
Thats what I want. I was on his 3D thread and it said he's still working on the table for the rom if have. I have 500 rpm - around 2000 rpm between 65 and 80. Its making it idle at proper afr's but im sure its way to lean for acceleration.

I thought the only issue outstanding right now was the jitter problem which I haven't quite figured out yet. As to the lean tip in problem from a light a lot of people make the mistake of thinking their VE stays the same at idle as it does as soon as you hit the throttle. The VE increase very rapidly in my experience right off idle if your VE is too low here the AFR goes suddenly lean for a moment until the RPM's rise enough you get into another VE spot on the map. On my personal car for example idle was around 72% VE and lugging the car around 1k rpms or so at like 70-100 KPA of vacuum or mostly full throttle got the car to experience up to 96% VE thats a pretty huge change.
I did finish the 9653 variant rom its on page 1 of my thread

Thats basically whats happening. I got the AFR's pretty close from idle to about 2000 rpm just revving it up. Then when I go drive it, It kills the engine when I accelerate because it hits around 20:1 AFR's. Ill try downloading the patch once more and let you know if I come accross problems.
Hmm, I already tried downloading it and it just gives me problems opening. Ill try it once more.

The other possibility is your higher kpa vs load table isn't where it should be. I set the table in the low region about 1:1 but thats not where a lot of cars like it so for all people playing the kpa vs load table is where you start and the VE table is where you end up fine tuning it.
Make sure you have the last xml's produced and if you don't already get a copy of the xml's from the tephra thread post #2.
I put my KPA vs Load table at 1:1 and started with the VE table. Ill raise the VE table back up and start with small adjustments in the Load table.
I already have all the xml's downloaded. I tried downloading the patch again. I try to open the zip folder and it says "the Compressed (zipped) folder is invalid or corrupted"

I think someone said I could directly upload to a wiki I need to contact him so the compression thing isn't an issue.

2d SD
ok after messing with SD for about a week I finally have broken down and have to admit i am very very confused. I kind of understand that on the RPM vs VE table the more u pull back on the VE the leaner your AFR should get. idk why it does i just know it does and you can correlate your front o2 giving you a -% with meaning to go leaner and you are rich (verified on AFR meter). I still have absolutely no clue how the MAP kPa vs Load works at all. I have to thank Roadspike on setting up the map side for me so i could get the car to run without being super pig rich. I have no idea how to scale either side of that table.
So far all i have managed is to get the car to run off boost almost on 14.7 for most of the time. in evoscan i still see the front o2 giving me a -%. Where it goes all terribly wrong is the moment i hit 0psi and greater all i see is AFR 9.6 and front o2 with a positive number.
More wrong: cold start= pig rich
Stop and go traffic = leans, doesn't accelerate for a bit. (tried async vs TPS) some improvement at +10 units across the board started at 5
Jitters= Fix 1 and 2 have almost completely eliminated that from light throttle cruise.
I have read thru the entire sd first test success thread and ended up i think more confused.
Thanks in advanced for those who help me also to the guys who made SD possible!!!

Also I am not dead lmao, just been sick and my car ate a huge nail so I am down till tomorrow I think when the new tires come in. Star specs to hankook rs3's. Hope they are good
I still need to fix the load cause during cruise on the highway it goes scary lean.
So I downloaded 7zip to open the file. I can open it up into a regular folder and when I try to open it with ecuflash it show's an unknown rom image error. I have all the updated XML files downloaded. Ive been having issues trying to pull roms off 04-newer subies and evo X's lately. Hopefully that isnt my issue. I also thought it was just in a patch not a complete new rom. Im apparently much slower at this technology stuff than I thought...

Finding this thread has definitely answered some of my 3D SD (and SD in general) questions, but Ive still got some more. And Im sure RoadSpike wouldnt mind me not cluttering his thread, hope you dont mind
So you are modifying the left and right side of the kPA -> Load map?
What caused you to use the scaling you did? (20,40,60 on left side and /or 0,25,35 on right) In other words, why not leave one side alone and only modify the left or right side?
What kPA do you idle at?
And as far as different map sensors go, the only table to that changes when changing sensors is the Map Volts (kPA) -> kPA table, correct?
I idle at 25-30 kPA. So if I was to use your kPA-Load table, I would be idling at 12-13 load. Am I seeing that correctly? Makes no sense. That is the biggest issue I cant seem to get around.
charlie right click the table menu and set the scaling to kpa 4bar.. by default roadspike has them all set to 5 bar since thats what he used to run in his evo.
the left side is the calibration scaling for the actual map sensor being used based on its voltage levels and the right is indication where its gonna be being utilized when its actually functioning at certain voltage levels on the map itself
your left should be about max 450 at the end for a 4 bar..
hope i made sense here.
