That pretty much sums up what I was experiencing. will be interesting to see your logs.

Hey guys, I'm running 1.56b stage 2 UEL with my OFH/Invidia OP/Stock FP/Q300.
I decided to take a log and try out the new channels available (I logged the first 100 miles after installing stage 2, it looked great). So I logged my commute to work this morning.


IAM started out at one, which I expected. When I got to work I noticed that IAM had dropped to .55! This was rather unexpected. I'll post a link to the log. Looks like I had three episodes of knock correction. Is this the light load knock that is being talked about?


I've never messed with Romraider, as I had been pleased with the logs upto this point, but I'm willing to give it a shot to correct the knock issue.


Here's a third gear pull, looks pretty good IMHO:

This should be the entire log:

Any comments would be great!

I noticed that AFR goes rich after 5,000 rpm. Is this normal?
Mods are in the signature.

Thanks in advance

*off topic*

Maybe you should let your oil warm up more before revving to 7k. I heard high revs with colder oil isn't a good idea. Anyone have thoughts on this? About how warm should the oil get before redline pulls?

I think you will have to accept a bit of knock and IAM dropping at times if you are running 91 AKI US fuel.

Either run better fuel or you will need to pull a bit of timing in the knock prone rpm/load cells where it occur's.

I have the same issues with this tune on 98 (your 93) and even 100 RON (your 94) due to differences in fuel formulation over here.

Same thing would happen on stock tune its meant to run 93 (98 RON) for best results.

I have had good results after pulling a bit of timing. ie no IAM drop and much reduced occurrences and severity of knock in 2000-3500 rpm range.

91 is the best I can get at this elevation. I looked at romraider, seems pretty straight forward. Where do I pull timing from, base Ignition table (and if so, I table A or table B)? Also, are the logged knock correction values in degrees? Is that how many degrees I should pull from the table?

here is what I did , note I am in Oz and out fuel is different so you may have to work in it a bit.

see link below

Table is knock correction max A or you could pull it from Base timing B, however I used knock correction max A table

First screen shot show "delta" or changes second one is actual table after changes.

You really need to log

RPM
Knock correction (FBCK)
Engine load

Note the RPM and load where the Knock correction occur regularly.

The IAM will drop as a result of repeated or severe knock noted in FBCK. This will occurr some time after the knock events.

Once IAM has dropped it takes quite a while to recover, will not recover if severe knock events continue. you can generally get IAM to recover with sone easy pulls to over 4000 rpm as long as no further knock events occur.

Don't worry to much about small values of knock correction such as -0.3 but if you see -1 or more its worth pulling 0.35 degrees at that RPM/load point. Watch for the knock events where the IAM drops shortly afterwards.

The area thats the problem is generally 2000-3500 rpm load between 0.6 and 1.2

As your on 91 you may have to pull a bit more than I did maybe 0.7 if you seeing corrections over -2 .

flash it and test, it may take a few attempts.

I log FLKC too as this can also highlight areas that don't turn up by logging FBKC. The knock event is also usually the row before the actual knock that has been logged and I will pull 0.35 in the cells surrounding the "prone" cell due to the way the ECU is interpolating as the load ramps up. Eg, if the knock even looks like it's happening at 2300 rpm within the 0.52 load range, I'll pull 0.35 deg between 2300 and 2400 in load ranges 0.4-0.6.

I do log flck as well but I guessed @Vmax911 has an OFT not tactrix or other device so will not be able to log that.

Was wondering if ecu averaged/interpolated values now have answer thanks

[Vmax911]

Thanks @steve99

Can anyone explain the difference between base timing table A and Table B? And how does knock correction max A interact with them?

And yes, I'm using OFT.

I'll try to get some this weekend. I have a pile of logs I need to get still, some WOT pulls to go with the normal driving logs to work out the MAF scale, and then some logs to watch the knock correction and IAM.

Should be a fun weekend of driving

ECUtek's base tables are ignition timing VVT on and off. Not sure which would relate to which but I would assume that's what A and B are. Most ROMs I've seen have them both set the same anyway.

The ignition advance table is added to the base timing. The amount is determined by the IAM and FLKC. Google RomRaider IAM and it's there in detail as to how the system works.

4 3rd gear pulls and quite a bit of driving in traffic.

stg1 1.56 after 400km on 100RON fuel (EU).
Only mods: Blitz drop in filter.
how is it?

Thank you for the explanation! So if IAM is 1, then I am running base map + Ignition advance everywhere. If IAM is 0, then I am only running straight base map. Anywhere in between is base map + (ignition advance X IAM)

Yes , but there are also other ignition timing compensations for IAT "Intake air temp and coolant temp and Air conditioner on/off ect probably some other to.
