Community Tephra Tweaking
Heck yes I am, MapTracer is the sweetest thing for knock count...and you can even edit your map in evoscan, while looking at the knock counts. I love clicking the knock count, and comparing it with the timing below
can anyone else set their knock thresholds to 0, so that ALL knock gets recorded and tell me if you get a big round spot of knock around 2250-2500 rpm? I am not sure if it's the tune or not, but just to cause some excitment and danger, if you've left the tephra rom stock, the threshold for knock is virtually unreachable by us in the lower RPM's...I don't think I could hit 160 load at <3000 rpm if I wanted to.
And Mitsu, did you try changing from big endian or little endian, whichever it is and then pasting those cranking values in again? I don't know which way is correct on yours, because that dang endian thing is confusing! Don't shoot me if something goes wrong though.

But, im going to try to switch it up tomorro! check out these logs bro, not sure if you can get any info from them? One is 03lances scaling, the other is stock tephra
Ok so dont know if any of this matters but I have been comparing my rom to yours mistu and have noticed a few things different. Tephra options you have airflow calcs enabled which I am not sure what that does but I do not have it enabled. Also ignition trim vs engine temp. My rom has all 0's and yours has 4's in the 18,45,68,93, and 122 deg F. I also see three tables in my global ignition settings that have to do with warmup enrichment that your rom does not, dunno if one of these may be different or not. Also all 4 post primer enrich tables in the main map fuel settings sections are different between the two roms, my tables have higher values through all of them. Idk if any of these will help your starting issue but I guess it would not hurt to try the other settings

Gotcha, could you send me your ROM/ XML so i can copy your settings into my rom, see if that helps any? I PM'd you my e-mail. Hopefully it will help and ill test them out today
If i dont have those 3 tables for "warmup start" can i just copy your scaling and what not and add them into the ROM?

I noticed when comparing the roms between at least the 3 of us, mitsu, 03, and me, that the startup tables and stuff are not exactly the same...some more tables, some less...but not always the same and the same numbers of tables or size.
So...my thought though was that since Mitsu and My roms are both VERY similar, like it looks like his is based on the 9653 rom....that I thought the table I changed should exactly similarly impact Mitsu just like me, but I guess wrong answer. So, they aren't as exactly the same as I thought they were.
I think I know what you are asking, and if it's what I think you are asking, then you can't. They call it "defining" a table, and it's basically what disassembling is all about I think. Find the table in the ROM, and then put it in the XML with pointers to the address, size/scaling and all that jazz.

Wow...I didn't expect that to happen. I've not seen the similar tables copy from one rom to another yet, the address is always different it seems. I'm thinkin 
for 03lances.
As far as logging, good deal on the serial cable, can't wait to see those logs. It's so much easier with the wideband in the log, only thing that would be even better is logging boost as well.

Ill give this a try right now, also ill post up the logs in one sec!
03Lances, which tables are the new ones? The ignition trim vs "xx" ones? Well started it up semi-cold, and Np, but when it was fully warm it still had to crank for a little to start, but it did however seem like it took less time, so maybe i just need to adjust some of those tables? Which ones would be best to try adjusting first?
Attached are some logs of today with the wideband logged! As you can see, i still need to adjust fuel somehow

I'm thinking if it was easy at cold, but tough when warm, adjust just the values in that temperature range that the car was at, aye? As for which one though....I'd still think adjust cranking ipw. Will it start if you push the pedal a little? If so, I bet you just bump those hotter ms values....if not, try lowering them.
Yeah, like you said....waaaay lean. The AFRMap shows "10" so that is the problem that the lancer roms suffer from, with the whole maf scaling thing, and the AFRMAP basically bottoming out at 10. If you get wicked knock at those values with MAF scaling, then I'm at a loss on how to handle that. It just seems it would be safer to be rich rather than lean. Did you get the exhaust leak straightened out? If so, I bet you should scale the MAF...just sucks to knock, so I don't get that....

Adjusting the maf will not change the numbers afrmap logs it will only change your actual afrs. The tables I added are in the global ignition settings its the last 3 tables in that section. They were blue in my rom and in urs top when I opened them. Can't remember the names off hand and I am at work.
Yeah, like 03lances says....the only thing you will see is AFR's that are lower, via the wideband input if you increase MAF scaling at the airflow value that corresponds. I wish MAF scaling wasn't the only way to do this though, because it's not the proper way to get it done. I have the same MAF scaling in my evo rom now that I had in my base lancer rom... but the evo rom drops AFR's lower than 10 in the AFRMap, and it's smoother at lowering AFR's as I go into boost.
Getting to the bottom of this is more important for mitsu.kid, because something about the rom he's using retained that "issue" that is also in the base lancer rom. I'm trying to see if I can find out why, but I seriously doubt I'm the man for the job on that.
