So i did a few logs with Evoscan today and i noticed that i have a lot of knock from 3k up. Mods: CAI, 4g93 IM Port & Polished, 59mm Throttle Body, RRM Headers, 2.25" Catback, RRM Lightweight Pulley

First off a screenshot of my High/Low Octane and Timing
Maps


Now the logs




I haven't touched the timing maps or the octane maps as of yet. I dunno if it has something to do with my mods but I shouldn't be getting that much knock right?

Please help me out with this..... Thanks in advance everyone!

 

there something wrong with the fuel maps, go to edit fuel map and check the box to inverse the x and y axis

 

He's right. In both fuel maps and both ignition maps go to Edit > Edit map definition... and then check the box labeled "Swap XY" in each map. Also, for your logging use "ECUload" and not "LoadCalc" to calculate engine load.

 

Just noticed that you did some work with my def file =P. your is coming up with the same problem as the other guy who helped me, it loads fine and the tables them selves look fine (though you addressed different values than he did they look identical) but the load and RPM values are all messed up. I tried posting a pic last time but it didn't work so ill try again this afternoon, this is both on a mac and 2 PC's so I know its not that causing the problem.

OK swapped the XY axis and it looks a lot better now. I cut back some fuel from 3k up and also had to back off on some of the timing cuz i was getting some knock( Knocksum= 2 to 3). So right now i got an AFR of around 12.5 to 12.7 from 3k up ad i'm working on pulling back some timing to get rid of the rest of the knock. Thats how it works right? PUll fuel then gotta decrease timing cuz less fuel means a hotter combustion temp which means higher tendency to knock???? Lemme know if im right or wrong on this.
Anyone else had to decrease timing as i did or did everyone just leave theres as s??

 

ok, so here is my maps, the units for both axis are all messed up from both the definitions that people have provided to me. When I flash the ECU with that def it works, but the car gets a clicking/rattling noise from 2400-3000 ( its a solenoid in the Throttle body making the noise ) so I had to flash it back to stock. Any help woul dbe greatly appreciated.

 

Yeah, whoever made your def file is using the wrong memory locations for your axis. I wouldn't touch your car until you got a correct def file.

 

any suggestions on who I can send to? I knoe the ecuflash forums have some people but if you have a specific name I would greatly apprecaite it.

 

It's a easy fix.... That's because you use ver. 1.31 and over. A very little modification in the definition file, we need to change some "endian" to "little" at "big" as the value. (Or vice versa...)

I have the same problem, if you use ver 1.30 or 1.28, you will have no problem with the scale value. (I found the fix on ecuflash forum)

 

If you do the change, post it. :-)

 

He's right. I am still using v1.29. I upgraded to 1.31 and had nothing but problems. I was unable to even read my ECU with 1.31. I downgraded back to 1.29 and everything was fine again. I just re-downloaded your 2003 OZ Lancer AT stock.hex file from a couple of pages back, opened it in ECUFlash and everything read just fine for me.

 

ill try it as soon as i get out of class today thanks.

 

As of right now I have an AFR of around 12.6 - 12.8 from 3500 rpm and up with NO KNOCK except for a knocksum of 1 at around 4k. I have tried decreasing and increasing timing but i can't seem to get rid of the knock. I don't know if i'm knocking cuz timing is too advanced or if i;m knocking cuz timing isn't advanced enough.

Heres a screen shot of my timing maps


My mods are CAI, 59mm throttle body, port and polished 4g93 Intake manifold, rrm header, 2.25 catback, RRM lightweight pulley.

Ive read some things about the knock sensor picking up other noises and thinking that it is knock(ex: rattling, dp hitting oil pan etc) but the pull is constant WOT so i figure the engine movement is minute and shouldnt cause anything to be rattling around that much.
Any help is appreciated THANKS!!!

 

A 1 count isn't anything to worry about. It sounds like you are doing well.

About the vibrations causing knock ... my DP hits my oil pan and it's fine except at around 3800 RPM. A range of about 150 RPM around that point makes the car sound like it's falling apart. So, constant WOT or not, vibrations can get worse or lessen with resonance changes in the engine. I will not that the vibrations in my car don't cause knock.

 

Try adding a bit of fuel to get your AFRs as close to 12.5:1 as possible. But with a low knocksum of only 1 it could easily be vibration as Touring stated.
