Data Logs! Post them here.

Hello,

As the weather got warmer I noticed even the most conservative tune I run (stage 2 91) is knocking lots. I've done some homework and implemented Wayno's tweaks including MAF scaling and base timing b map.

Over 3 or so revisions with open loop logs I reduced some timing (little at a time) where there were FLKC over -1. Today I implemented the IAT compensation as my revisions weren't doing much in reducing knock so I figured it was the hot weather.

I logged today after flashing these tweaks and recorded an all time low IAM of 0.46. Knocking like no tomorrow.

Can someone please look at my logs and tell me if I should delete this map if I molested it beyond repair or it is indeed due to hot weather and/or shit fuel?

The second log below was taken when my transmission was acting up again. It seems there are spikes of throttle up to 95% when I was applying throttle like a grandma the entire time. What the fuck?

http://www.datazap.me/u/richardfrs/j...=1&data=1-2-12

I flashed back to stock for now as it is going into the dealer for an oil change tomorrow. I might ask them to reset the TCU to fix the transmission issue i've also been having.

Thanks so much in advance.

Have you tried different brands of fuel ? Some are way better than others.

Looks like it might be fueling problem, looks like afr goes lean initially on throttle then it knocks.

Hey Steve,

I have tried different brands of fuel but in regards to the transmission issue it happens all the time even with 93.

How about the first log? Should I stop taking timing out here and there and just find better fuel?

So I've been running @Wayno 100 STG2 UEL for some time now, it runs great, instant torque! Had the car dyno'd and the final output was a bit disappointing, just shy of 200 bhp, another 86 (stock with KN intake), did 186 bhp, so i've spend over 1000 usd to have stock power .. yeaaahh :P :



In the hunt for more power I tried the Wayno tune with 102 timing and suprise suprise, no flkc in the high revs, just a bit in the mid area. With the help of @Tor and @Kodename47 knock correction tool, the tune was further perfected, I now run this timing (compared to Wayno 100), which is also a bit more than the 102 default timing. I'm using BP Ultimate 98, the car pulls like crazy and I think the log looks very good (also the log contains multiple pulls at 25C):

Can't wait to put it on the same dyno again

Have a look at the roms at end of this post from wayno , while they are A01G and for our 98 fuel which is close to your 91 , the timing and fueling changes in their should works for you if you transfer the timing base b, knock corrdction max A, open loop and closed loop fueling tables and possibly the maf depending on your intake. And mayve iat comp tables.

Be carefull with iat comp table that you put in negitive values, if you leave out negitive it will add timing, same wirh closed loop fuel tables weird stuff eill happen if the negitive not put in

Our 98 in Australia is very poor compard to european fuels hence you can run much more timing.

15 wheel hp over stock car on same dyno is pretty good. As the guy had intake they generally lean out stock cars which run overly rich and can produce a few hp, so if that was worth 5 then you would be 20 over stock with tune and header which is pretty normal gain

And with all that added timing it's probably good 5 more HP up at the top - so 25 over stock is not bad.

Thanks for your reply, yes our European fuel seems better, but this does not apply for all. Here is a log of my Belgian friend on the 100 timing, where you can even debate if he should run the 98 timing (or see if he can get similar 98 fuel to mine), but it seems to differ per country too.

Yes for sure even different brands can produce very different results

Woah Steve I copied the tables you told me and I have absolutely no knock!!!

Thanks alot man as always

Edit: Initially wrote that the car was feeling sluggish but then I realized I have weird values for IAT compensation- just like Steve warned me lol. Car pulls amazing now!

just posting some logs again after driving few days which ECU can learn

3rd gear pull

Bit of knock to sort out 2000-3500 thats dropping your iam, running a bit on the rich side at wot 11.3 should be arround 11.8

yeah that happened when i lifted my throttle suddenly

still little rich as well...i didnt have time to educate myself to fix

Wondering if I can get someone to give me a brief run down of these logs.

http://datazap.me/u/captindecisive/s...af?log=0&data=

^This first log is with a fresh flash to ROM JB01C with a Perrin 3" CAI (with Perrin values added to proper MAF area), Perrin inlet tube, and Perrin 3" catback. Running 91 octane.

http://datazap.me/u/captindecisive/s...af?log=1&data=

^This second log is the same setup, mod wise/fuel wise, but with a tune I paid for.

I'm extremely new to tuning, and logs, but everything seems ok to me from what I know. The tuned flash definitely feels like it has more power in the end of the torque dip, around 3700+, and top end feels slightly better. But I'd like someone with experience to give a brief synopsis on what they think.

Thanks for your time!
