just flashed to OFT stage 1 last night and datalogged a WOT pull in 3rd today. seems to be running pretty rich...

Any trusted tuners near los angeles?

Maybe a little bit rich, I would look into scaling your MAF, you have a perrin intake right?

looks good to me.

imo not exactly 'looks good'.

does look a little lean doesn't it?

thanks.

looks good to me.

That log is weird

Engine load arround 50 should be 0 to 1.3
KC Learned negitive values thought it should only go to zero
IAM staying at one with supposedly large amounts of FBCK like -5 sustained that should have dropped your IAM to less than 1

Looks like your log RAM addresses and scaling are not right it just does not make sense.

did you flash a B00C ROM and using A00C addresses or something ??

[QUOTE=ML;1723268]Maybe a little bit rich, I would look into scaling your MAF, you have a perrin intake right?

yeah in the process of scaling my MAF. collected lots of data and sorted through all of it. just uploaded my updated ROM with corrected MAF scaling last night and datalogged my drive to class this morning (approx 20 min drive). we'll see how it looks when i get home later today. oh and i have an FA20Club V1 intake

the load has either wrong addr or scaling, there is engine_load which is correct. kc_advance does go below 0, kc_advance_aim - does not. i don't see iam dropping due to flkc or fbkc - it stays at 1 and when it does drop i don't see why maybe addr is wrong, but that's what i have for a01c

in the tactrix thread I started I posted up your logcfg.txt and one from adrianG might be worth trying his logcfg.txt ans that log just does not make sense to me.

Have a look with hex editor at the ROM and make sure is not a B01C series sometimes the OFT stuff update to different rom I know they do it for old 700C to A01C


this is tactrix log of A01G rom for comparison

what do you suggest i should be looking for in the hex editor? if shiv did change the tunes from native a01c to b01c then he updated the ID's as well. Otherwise it wouldn't be loaded neither by EcuFlash nor by RomRaider as I don't have b-series definitions. And if not just a string ID then I'm affraid I won't be able to tell from just hex values if that modified ROM was originally A series or B series.

It would probably be just the string ID to "fool" the OFT to let it load the ROM. Was just guessing , more I think about it its not that.

Beats me whats going on, looked at the xls file it still confuses me throttle and load very jittery unless your foots vibrating on accelerator pedal lol

Try logging a WOT run from 2000-6000 its much easier to get your head around.

Tactrix site has "official" beta release up now newer version and also updates firmware in tactrix dongle

Yep that looks better and easier to read

extracted this bit WOT run

http://www.datazap.me/u/vgi/newtesta...zoom=3810-4375

AFR looks ok probably a little bit rich 11.8 at high rpm (shiv targets this for safety)

LTFT look's a bit high 5-7% maybe a maf scale ??

maybe another -0.5 degrees timing pulled around 2800-3200, engine load 0.5 to 0.7 or there about its prety hard to completly eliminate but if its less than 0.7 should be fine. Seen stock tune register 3 or more degrees in that area.

That area around 3000 rpm is where your ltft is about -5 to -7%, might be worth doing the CL maf and get it a bit better that might fix the knock a bit as its going to remember that -5 to -7 when you get on the throttle (tip-in knock) and maybe run a bit lean

Ok, I finally got around to doing a data log after work on the way home. Here is a 3rd gear pull with an OFT Stage 2 EL BPB 93 tune. What do y'all think? I'm trying to learn this.

Guys can you check out my datalog?
I'm running OFT Stage 2 UEL E85 tune + Borla UELs + Snorkel mod + Muffler delete.

I flashed the tune approximately 90 miles ago, and I did 2 quick WOT runs.

I think my AFRs are a little lower than they should be, and LTFTs a bit too high...

Also.. I'm still diagnosing it but the headers might have a small leak around one of the flanges... would this have anything to do with it?

take a look at this log tell me what you think.

No takers?
