check the knock correction max A tables as well as total timing is Base Timing B plus Knock Correction Max A. I think you will find wayno has shifted the amount of timing in the knock correction table

Thanks Steve.

I must confess that I just scanned the Base Timing B table and noticed the more aggressive values in the higher load / higher rpm range (compared to OFT OTS).

I just checked the Knock Correction table and see your point .

I don't like to make changes base on one single pull alone. Though, if you are uncomfortable with the amount of flkc you are getting you can try pulling a bit of timing from the base ignition advance map b, subtracting 0.34* starting from 5800rpm at 1.0 load and up all the way to redline, then retest. Also, you should be logging engine loads in your logs.

I ending up purchasing a Revworks UEL header from a local forum member and installed it on the weekend and flashed using Stage 2 UEL 93 OTS tune. My logs look much better but seems to be on the rich side now.

Hi guys,

Interested in any opinions on the logs below - I am still working through some -FLKC.

The tune is an OFT OTS Stage 1 tune (v2.076) with modifications made to timing (Base Timing B and Knock Correction Advance Max A) for Aust 98 Octane very closely aligned to Wayno's brilliant work.

A few 2nd/3rd WOT logs.

General driving.

Unfortunately no Knock Correction or IAM fields via OFT as I have a D00G Rom.

Thanks

dude can you send me your tuned BIN file for a try, I have D00G too with no IAM etc?

interesting...I was experimenting with Wayno's v107 map last night by copying all his new modifications to my tune and I noticed when accelerating when driving around, there's a weird spike in commanded afr where it goes lean around 3000-4500 rpm around 0.9 to 1.0 engine load.

It sorta does the same thing on fibble's log as well. Not too sure what's causing it....new MAF overrun settings? (I'm not too sure what that does) Care to chime in Wayno? I don't think it's a big deal considering actual AFR is trending in the right direction but that commanded AFR spike is kinda weird.

MAF overrun tables define the target airflow on the overrun, used to adjust engine braking. These are not active when on throttle (surprisingly).

That's normal. This happens right after transition to open loop during partial throttle. Commanded AFR seems to peg to a static value that AFR doesn't follow.

Beyond seeing that pattern, I've got no clue why it happens.

Looks good. The OTS stuff from OFT typically runs a bit rich. Also considering that the IAT were at and below 68*f since the engine will tend to run richer in cooler conditions on top the the LTFT you are getting in OL. I'd just leave it alone and see what the AFR's look like after some learning and with warmer IATs. You dont want to adjust the OL fueling to suite cooler temps then to be too lean in warmer weather. With the stock MAF IAT compensation you'd want to error on the rich side so you dont go too lean in hot conditions.

Just to be clear - my logs are based on timing tables (Base Timing B and Knock Correction Advance Max A) + the timing temp compensation values (which are not currently really in play - our winter) based on Wayno's v106.

All other values (including fuelling) are OFT OTS Stg 1 v2.076.

Ok thanks I appreciate the feedback!

Surprisingly 3 out of 4 WOT pulls are showing no sign of knock. (2nd, 3rd, 4th gear, even road, uphill etc). But on one it is showing a little of "knock".
Dont know if the AC was on when it happened.

Shouldn't it also show on the other 3 if it is "really" knocking?
And the AC compressor also definitely triggers FBKC sometimes.

AFR&Commanded AFR are looking sweet. LTFT also.

Gonna guess it could be rising ambient engine or IAT temps? If IAM is perfect and it's detecting less than a degree of random flkc here and there, the ecu doesn't pull alot of ignition timing that will impact overall power...I think? That's what I noticed on my logs.

Look for common factors; intake, coolant and oil temps play a part.

Depending on settings, but usually even if IAM drops to 0.9 the timing advance loss is less than that of FLKC retard during WOT.

My IAM dropped only once at 0.98.
IAT Compensation Table is already "aggresive". But i think i i'll leave it and let the ecu handle it. If it showed flkc/fbkc constantly then i would be worried. IAT was at 95f-100f
