Holy cow that is a lot of knock on the upper RPM range. I wish there was a way to gather the timing and the AFR during the run ....

 

THis worries me and I'll definitely have to get on a dyno as soon as possible and log mine....

What does Works have to say about this?

 

The timing is left out because it's a vendor map. Remember the rules?

I can say however that it only is running 5 degrees @ 7000 rpm because of all that knock pulling all the timing.


Octane flag is what determines what map or inbetween what maps the car runs on, anything over 7 knock counts the octane flag drops from 100 (or 255 on earlier evoscan versions) and starts interploating between low and high octane maps.

It is in HZ and evoscan and most obd2 logging apps max out at 1603 even though the HZ does indeed go higher then that, it's a logger limitation, not the car.

They all got the correct $600 WORKS flash for 91 octane.

 

+1 I hope WORKS chimes in on this very soon.

 

Bryan, thanks for the input. The 5* timing at 7k is tells us everything we need to know...

FastAzzEvo, you don't need to get on a dyno to get some logs. Get Evoscan and Tactrix cable, hook it up, and go do some 3rd gear pulls - that's all you need to do.

 

And what does that tell you warr? Nothing. Nobody could tell crap without seeing the tune. Im not going to make guesses at these personally. Without knowing the load, rpm and timing you cant see jack crap.

I hate to break this to you, but works are more conservative then your "sponsor's". Lets talk 8* blocks of bull$hit buddy. Your right, I was quick to call you out for vendor bashing on the other thread about cosworth cams. Im glad you pointed me over here where your REALLY throwing it to em. How many times have I seen you whoring in the WORKS forum? Do you really have any need to be there except to be an a$$ and talk crap? Nope.

Heres the deal. I have a works p2r. I had it on the dyno. My afr's were 11.4-11.1 at redline. I do tuning here on my own car, and have used my $600 flash as a starting point in making a meth map. Its VERY conservative. Ive seen dynoflash custom tune maps, baseflash maps, etc. Thats how I can say its conservative.

Heres my point. My flash is for 91. I log my car ALOT. Its a habit, just about every day actually. The other day I was playing with a flash and got alot of knock. I fashed back to works flash to rework that one I was playing with. Couple 1-2 counts here and there to redline, 4th gear pull on the freeway. Havent changed the flash since then, but filled up with sinclair gas yesterday. Guess what? 19 counts of flippin knock up top.

ITS PROBABLY NOT THE TUNE. Test your gas first, seriously. Ive seen knock from one gas station to the next. 91 is flippin crap, and its impossible to tune on. Specially when you might end up with 87 like it seems like I did the other day. Bad gas does happen.

 

DUDE, way to flip out and go completely psycho. You just made yourself look like a complete idiot. Warr was nothing but beneficial and a help to this topic, you just completely threw it off topic; way to go JACKAZZ!

 

How many Works tuned Evo have you dynoed? I can say from personal experience from several Norcal dyno days that Works base Flashed car consistently make less and less whp run after run which clearly demostrate knock activies. I have seen AFR as lean as 12 up top....you might argue its not just all about AFR but I wouldn't want my car that lean with 91 **** water. FYI, I was the dyno operator at times during those meets.

You said their tunes are safe? So does it mean it shouldn't knock even if you have a bad tank of 91? Well...maybe if the gas station is selling you 87 when you paid for 91 otherwise I don't think a "SAFE" tuned should have that much knocks with any 91 octane.

 

wow, everyone is so quick to point fingers and blame the tune. do we even know this car's setup?

According to that log timing is probably around 15* @ 7k which isn't to aggressive for 91oct and normal boost so something is up with the car.

First thing I noticed was the inj duty cycle is over 100%, the next question I would ask is what are the A/F's and how much boost is he running.

 

How do you know what timing its running from those logs?

 

WOW, where did _THAT_ come from? Where in this thread was I "REALLY throwing it to 'em"? I haven't said a damn thing negative or derogatory. It wasn't until Bryan told us the timing at 7k that I was able to make any sort of determination. You do know what 5* timing at 7k indicates, right?

Then, what's this about me "whoring" in the Works forum? Are you insane, or are you just trying to slander me hoping no one would notice? If you do an advanced search for POSTS MADE BY WARRTALON in the Works forum, this is the result:

Sorry - no matches. Please try some different terms.

If do an Advanced Search for the WORD "Warrtalon" in the Works forum, you get _1_ hit, and guess who is responsible for that one hit: you. Here's the thread:

YOU quoted ME in the Works forum where I had made positive comments about the Works O2. Ironic how you bash me for "whoring" in the Works forum, when in fact, it was YOU who whored ME in the Works forum. Amazing...

As for the cursing and bashing of Dynoflash, you are really going off the deep end. You don't even know why there are 8s or what the effect of those 8s is (no effect) - you just read what other Dynoflash-bashers say and regurgitate it. Al can just as easily put different numbers in those load cells that NEVER GET USED UNDER ANY CIRCUMSTANCE just to make it look pretty. I know, because I have the same "map" with and without the 8s that makes the same power with the same results when logged. It's a joke how you people freak out about it. Plus, I'm not bashing anyone, but what you just wrote here is an outright malicious case of bashing.

You might want to calm down...

 

I wish I knew what you guys were talking about.

 

I'll admit, No...

Care to give us the short version

 

Timing should peak around 17-20* by 7k on a car like this, so if the timing is 5* at 7k, then that means the knock sums we're seeing in the log on the top end are having a DRAMATIC effect on timing. It is not phantom knock - it is actual knock causing the ECU to pull a severe amount of timing in order to save the motor. A timing pull usually is 1-2* at any given instant, but to be 12-15* below normal at 7k indicates a serious problem. It's not necessarily the tune, but there is definitely a big problem with this car.

 

Warr,

This is a Evo 9 so timing at 7k is usually around 12-13, 15 or maybe a little more past 7k. Either way its pulling alot of timing.
