Hey all,

I've had BM3 for a few months now, but have never explored logging. I'm running the Stage 1 93 Octane map, and am considering going to Stage 2 after installing a downpipe. I'm not really sure what I'm looking at. Can someone tell me if there are any problems? I don't want to go to Stage 2 until I find out it's running well.

I did a couple pulls in 3rd gear starting from around 2500-3000rpm. This is what BM3 recommended on their site when logging. I did one in 4th gear too.

Timing seems to be off later in the RPM band. Why is that and how can I fix this?

What is the "Knock Detected 0/1" line?

Thanks in advance!

I'm not a tuner so take my comments with a grain of salt, but your logs look pretty good actually. You're hitting target boost, your IAT's are good, and your HPFP is right on target. If you're worried about the timing, I'd try a different fuel (stick with top tier gasoline). If that doesn't seem to help, try running the 91 oct map (with 93 octane) or you could try some octane booster. Worst case scenario it might be time for new plugs.

Knock detected is exactly what it sounds like -- if the DME detects knock it will show up as a value of 1. Don't worry about it unless it appears!

I echo everything outofphasesaid. I'll add that my logs look just like yours with respect to timing. I am going to try the 91 Oct map and see if the timing cleans up.

Thanks for the comments! I live in MN and use Shell's 93. I'm still on stock plugs, which have 53k on them. Sounds like replacing these wouldn't be a terrible idea?

53k is way too much on plugs when tuned bro I’d change them

I didn't tune it until 45k, but I hear you. I've read a lot about properly gapped NGK's if going to stage 2. Will have to do this soon!

NGK are the way to go bro when going stage 2 and change them at like 18k-20k miles.

Does anyone know what timing values, or differences between cylinders would be concerning?

Send your logs to PTF

+1 to what "outofphase" said.

The knock sensor is a finely calibrated microphone that listen to the engine. Before actual detonation/knock there is a sliding scale of sounds the DME can react to which is what you see when timing is retarded ~3 degrees in your log. All in all though, those retards is an indication of the engine being on the limit of what it can do with the octane available. What is seen is nothing to be alarmed about but as said before, you can go down to a lesser octane map or bump the octane to have the engine run with a bit more safety margin.

Thanks! Damn, already using MN Shell 93. I'll buy the map pack, and try the 91 tune to see how it does. I'm assuming when I go to stage 2, the 91 map would be best to use based on my crappy gas?

The question I have is why's it detecting knocking when he has 93 oct map while using 93 oct? What's the point of even having a 93 oct map if the 93 oct gas isn't gonna hold up? Asking because I plan to go from stock to stage 2 93 soon and all I use here is 93 gas

Good question for PTF. I'd ask if I were you.

It's not detecting knocking. It's apparently the counter. So if there was knocking, it would show up as a number.

Ahh okay I get it now, thanks!

I think the problem is in the USA and Canada you guys have shit fuel which is often labeled as 93 but is in fact not on par with the quality its supposed to have. Just my observation/experience.

Another problem i see is people are obsessed with power gains which makes tuners go for OTS maps that are too aggressive for being OTS maps maybe? like why would you want the most aggressive and not the most safest for ots? i would.. but i guess most ppl just want gains..

with so many ppl needing to add additives to their fuel to have smooth timing etc, i think the best for most people would be to go for 91 map and tank 93 gas..

thats generalizing it a lot of course and everyone can do their own logging with the fuel thats available and act accordingly.. its just a conclusion iv come to by reading these forums daily

I'm going to try this and I'll report back with the results!

I have done this recently. I am now running stage 1 91 and using 93oct gas. timing still looks rather shitty. frustrating...

Most fuel here is garbage but I've done some shopping around and have at least found a couple top tier branded stations that seem to be decent.

I think maps are also getting more aggressive just because ECUs are getting a lot smarter. I remember the OTS maps available for my 04 WRX back in the day being super conservative. I have a feeling that most computers are so quick to adjust timing and throttle angle and calculate load that it's significantly safer to push these cars because it's like having a nanny

Would anyone be able to review this 3rd gear log and tell me if it looks alright? 3rd gear pull had to slow down right at the end for a cop.

Took a quick scan through. Nothing jumps out at me. Timing is clean as a whistle.
