I'm on 9417 2.0, and it seems to be working really well. I tried to use the 9653 SD1.0 rom you guys are all using, just so I could compare and contrast....but I couldn't hardly get it to run at all. Maybe that means my injectors and maps and all that are just so far off from my own adjustment or something, I dunno, but it idled so lean and I just got tired of it.

Regardless of that, I wanted to ask a question and see if you guys know anything about it. Being that I use 2.0, some stuff may be different...but sometimes I'll just be driving along, doin my thing, and it's on hot days only I think, but my WB reads much leaner at idle and cruise than it was when the car warmed up and all that. Thoughts on why that might be? Like, is that baro value getting set or something and then changing because of heat soak or something...I really have no clue, I guess I just wonder if that happens on the SD1 to you guys as well.

That 3D VE table is wicked cool, but I hate that around 2500 rpm, my numbers drop significantly, like it goes 122, 121, 120, then 117, 114, because as my rpm goes up, just past 2250, the car starts running a lot richer. Maybe it's something else, and I'm just correcting it with VE...I dunno. Still, no jitter on the 9417 rom, but there is in the 9653. It would be cool to have both working, but like you said....jitter is tough stuff. I'll badger roadspike next time I see him on IM and get him to quit his job and go full time rom dissasembly.

 

I finally got around to using this thing today. This is my first time ever trying to tune on speed density, so bare with me.

I downloaded the IX rom and copied all of my current tables over, fuel maps, timing maps, etc. I left all of the SD tables alone and loaded the rom.

To my surprise, the car worked perfectly. I had absolutely ZERO issues. Something has to be wrong with this picture. I've attached the most recent log I made so maybe someone with more experience can tell me what the heck is going on. I don't believe that the stock rom would run so well on my car as modified as it is, especially being a 2.4L with massive cams.

1) I did not disconnect my MAF sensor. Could this cause the car to run well with a SD rom uploaded?
2) Where do I go from here? I've been trying to following scheides tutorial on SD, but my trims seems to be doing ok. I've attached my most recent log. Someone help me out here!

Lol...almost runs too well aye? That's good news though. One reason it might run well, is that the 3d VE table is intended for an evo engine....but like you said, it's a larger size engine, so I don't know how VE changes with that. Cams change it for sure...you sure you flashed it? lol, jk jk

I had a ton of trouble getting SD to run, but I have a totally different engine than the evos...so it's understandable.

 

can we tune the 8859 rom SD tables with live map ?

 

donner has been working on livemapping for this roms

 

Yes i see, they have it for the 88580714 EU Evo 9 rom maybe I will ask him for a try because I have problem on 2.0 liter 20g turbo Evo with load value. Maybe with SD rom it will more stable . Donner with that rom you can tune the SD maps too in live ?

 

I have ported livemapping functionality to 96534706 and SD2.0+live to 88580714. Yes, I can tune VE map with live application but atleast 9653 version still has one small issue (you can use rom for tuning though) and 8858 is not widely tested (just quickly on my own car and it worked fine). I have sent 8858 version to only one guy here but I have not heard how it went in the end.

 

I've got SD 2.0 running on my car. I might be experiencing the jitter, or it (probably) is just that I haven't had any time to tune the car at all. That said, the car drives pretty well, but the idle is high, like between 1600-1800 most times. Every once in a while, when I come to a stop, the idle will drop to like 1200 momentarily, then jump back up, kind of like standard idle surge, but the drop and rise aren't the same speed. Commanded idle is like 1200 (depending on coolant temp) but it never idles that low. Idle load is about 40 right now. off the pedal throttle position is 14.11%

 

Apparently I'm an idiot and the reason my car was driving superbly was because I didn't disable closed loop.

I'll report back with my results.

any results acree?

Ive just started again myself

 

Still not understanding what I need to log kpa. Ive seen a few threads that mention it, but there wasnt any mention of a eval formula for a omni 4 bar. or are they all the same?

 

In evoscan set equation for MUT38 as follows:

P[kPa]=1.632679*x

You can create your own or use some existing item for this, as you know all that matters is this formula

 

One thing I see is I can dial in ve but it is not consistent at all. Idle takes 85% sometimes to get near 14.7.. and in ten minutes its way off.. always after a short cruise to avoid heat soak

 

I find things like A/C on vs off make a difference in KPA, or load. I also find that I run lean when I warm up sometimes, but once warm it's fine.

Also...I find that running in open loop is really good for getting things dialed in close, but once you get close, you can't be too nit picky about it, just set closed loop thresholds, and check your trims from time to time...it's going to be fine though. You've got to let that computer do what it wants to do, no sense in running open loop all the time, ever to increase AFR at cruise...it doesn't make an mpg diff for me. For me the MPG diff comes from fine tuning timing in that area.

 

No ac and in open loop. I'll give it another shot and see if it will idle in ol decently.

Well it looks like 79% to keep high 14 low 15 after a cruise.. started a couple low rpm pulls and my kpa reads like 240 while my 1b load reads 300@ 20 psi on my 71 hta. I tried taking the load at each kpa and scaling my kpa load table that way. I didn't see a difference .. is this what easy speed density refers to ?
