All you aussie guys will be better running @Waynos maps

Stage2 UEL Map

Car was warmed up for 5 min, then a short drive with 2 small pulls at the end. Just want you guys to take a look and make sure it all looks normal. Car runs great for the most part although last night had a weird hickup under <15% throttle a couple times, did not happen during the log or at all this morning.

Iam is 1
no fbkc
you did not log flkc but looking at the KC Learned looks fine

the only issue is its running quite rich 11.2 and while thats safe it will cost you some power , you will need to do some maf scaling to correct it, the bogging at low rpm is likely due to load limits

[Wayno]

All the openflash tunes are safe in the short term due to the factory ecu logic, they just may not live up to their potential is all.

With mine all you need to max them out is select between 2 maf scales.
If you're on E85, flash the US.Rich scale, drive 150km after flashing or filling up, then log WOT 3rd gear from 2500-7500. If it's richer than about 11.8 AFR @ 6800 then switch to the US.Lean scale.

Just don't base decisions on data logged straight after flashing on E75 or so, because fuel trims won't have settled correctly.

The process is the same on 98 except that you can log after filling up, provided you haven't switched from E85 recently.

Just to check 100% - I think you are saying that aside from checking MAF scaling on Stg2, you feel that your Stg1 and Stg2 (Petrol and E85) maps are safe enough for us to run (on Aust 98 and E85) even without visibility of FLKC, KC, IAM, etc?

Are these the v107.2 files at the bottom of your helpful post here:

http://www.ft86club.com/forums/showthread.php?t=83945 ?

I imagine we use the v106 definition files you have listed?

I assume we use A01G as the base?

Unfortunately, not all tables are the same scale/values across ROMS so a little bit of extra work to convert for D00G (e.g. fuelling).



Agreed - same on my logs. This supports my assumption that Openflash pushed an update to OFT over the last few days via OFM.

Cheers

FLKC was also reduced.

Also, it seems that my FBKC is going crazy with AC activated, everytime the AC kicks in and i am on the throttle it seems to detect "false knock". Is that normal?

IAM dropped down to 0.98, but i think it is because of the AC. I will give it a another week of learning time for the knock-sensor.

AFR / IAM drop: http://datazap.me/u/rezi/16063?log=0...rk=3357-819-93

FBKC with AC on: http://datazap.me/u/rezi/16061?log=2...zoom=3140-4880

FYI, Intake Temperature was around 87F-90F

Out of curiosity I took a couple of logs with my AC on. No WOT to redline pulls just regular driving loads. Aside from some tick tack flkc here and there (-.34*) there's no knock correction worth noting. My fuel trims actually look slightly better than with AC off. That was rather unexpected. Fuel trims will tend to go a few percent positive at and near idle speeds with AC on. My high temp fueling compensation was slightly off toward - fuel trim. With AC on, it evened it right out to 0% LTFT. lol

http://datazap.me/u/solidone/z6-kc1h...&data=1-8-9-11

As knock free as this log looks I'm pretty sure if I punched the throttle with the AC on I would see some knock correction where I typically wouldn't or more knock correction where it is minor with AC turned off.

The Knock Correction on mine happened when i stepped on the throttle with AC on. When the AC kicks in i can feel it, so can the knock sensor?
On WOT the AC automatically shuts off.

Anyways, i'm gonna stick with wayno's v107 98 stg1. I think i ruined my tune with pulling timing over the couple of months. It doenst feel peppy anymore between 4000 and 6000 when WOT :/

A friend of mine has OTS stg1 91 from vishnu. He has absolute no knock, never, even if it is hot. Overall i am running about 2,5degree less advance. And this is driving me nuts.. And he is driving with 98 octane i never heard of.

I rarely take logs with AC on, though I always have my OFT hooked up. So the change in fuel trim and knock correction is just something I observed. I don't really bother with AC since I always turn it off when I'm driving the car hard. Maybe it's more of a concern for others, but I dont worry too much about performance with AC on unless I catch something really off, which I haven't so far.

Why not try the fuel your friend is using? Maybe it's just better fuel he is using?

[Rezi]

Wow..

Wayno's v107.2 Stg1 solved all my problems.
Zero knock on WOT, unbelievable...

Hey guys, ended up picking up an OFT and flashed the stg2 EL E85 map onto the car.

I'm not getting anything at all for my IAM, and the FLKC is consistently -5. From the other logs I've seen that means its pulling loads of timing, right? It seems really odd that it never budges from 0 at anytime, so maybe the ECU didn't take the flash, although it seems to run very well.

The CalID for my car is ZA1JF00C, iirc.

it looks like the logging does not work for soke parameters on your rom, contact the oft guys.

from what i can see it looks ok using kc leanred.

logging for flkc iam is not working correctly

[CZ6T]

I've sent them an email, so I'll just have to wait and see what's going on. It's a releif to know it doesn't look realy terrible, though. I'll take it easy for a few days and see if it starts developing knock or not, and hopefully the ltft will be nice.

you can see knock with the KC Learned parameter, you need to open your tune in romraider and go to the Knock Correction max A table then compare the values in that table at some load and rpm points to the kc learned values you see in log if they are close then you have no knock and iam is 1, i had a quick look and it seems fine

afr looks ok and ltft is ok for e85

Hi guys,

Stock D00G car running Wayno's Stg 1 98 v107.2 tune.
Fuel - Caltex Vortex 98

2 Logs attached:

http://datazap.me/u/fibble/oft-stage...o?log=0&data=1

Note: ignore FLKC due to problems with OFT.

Still seems to be some knock and trims look a little out with AFR a little rich.
Thoughts on whether there's still work to be done (timing and fuelling) or acceptable for Stg 1 tune on my car?

Wayno - this is with AVCS in v107 (not experimental).

Thx

KCA Max A attached below:

[Wayno]

Looks fine to me. It may get leaner. Do at least 150km before you judge fuel trims.

No probs - will do the extra ks.

Also noted experimental Stg 1 AVCS is significantly more conservative on both Intake and Exhaust.

Something you found or suspect?
