what happens if you have knock counts but your timing is advancing just as below?

8 16--------------------60000rpms
8 17
8 18
8 19
11 19
11 21
12 22
15 22
15 22
16 22
16 22
16 22
16 22
16 23
15 23
15 23
15 24-------------------------7800rpms

the timing stayed still why didnt went down with those knock sums?

i ask cause people using a pocketlogger to tune would only see timing and not knock sums if seeing this they wouldnt worry!

 

How bout zipping up the log so we can really see whats going on?

What are those two columns for example? Timing then knock? visa versa?

 

Is this with evoscan?

Did you tune the Maps with ECUFlash?

What Octane fuel let you run 16* at 6000RPM?

 

he told me in a email that he is using xede to tune with. I told him to take the piggyback off and tune the stock ECU using ECUflash. I'm not sure if he took my good advice or not.

jrsimon, can you zip up the logs and send em to me VIA email? or just post them up here.

Thanks!

the first colum is knock sums the second colum is timing advance iam using the xede cause i cant tune the ecu this is using evoscan
know my question is why with that amount of knock the ecu kept advancing timing and holding it?
the afrs are at 11.0

 

here is the attachment this was a 3erd gear pull

 

then i modified the xede map and here is my next log but iam still curious on why the first log i showed had knock sums but timing kept advancing it didnt go down as on expects it to do. imagine someone using just pocketlogger they would think the car is fine

 

Just because your logger does not show that timing is getting pulled that does not mean that it is not. Since I have your stock map, I can compare it to the log.

For example:

At 7K rpm you are getting 15 KS. Your logged timing is 22 with 165 load. but your map says that you should be @ 27* at similar load point. Since 3 ks usually pull 1* of timing, 15 will pull 5*. 27-22=5* So there you have it: your 15 knock counts pulled 5* of timing.

 

nj thats what i did with my map and my 2nd log shows no knock i pulled from the xede map -5*
i started this thread cause i was curious on why my timing never got pulled back
imagine using a pocketlogger to tune as many people out there use they wouldnt be able to see the knock.

 

BTW here is my jdm rom for you guys to check it out its more aggresive then the usdevo roms:

 

Not sure its the same but on all my DSM tuning with piggy backs if your inj are to big and you are in the 70% DC the ECU will not think the load is much and you will get lots of knock and the ECU will not do much or the fact that you are in a low load table with lots of timing High 20s and it only pulls it down to low 20s. In all my years with tuning DSM I have found I like to really match the inj to the setup so I am in the high 80s on the DC.

 

i think my DC by 6000rpms is 85% iam using stock injectors but scaled different then the usdevos
