That's exactly what I did last night

 

Anything over 2.0 volts should be considered real knock.Also the 02 dump can cause false knock as well. How are you able to get away with 4-5* under/ around peak torque on 91? What is your A/F at peak torque?

 

The waste gate isn't open at 1-3 psi anyway, I'm at 4600 ft and afr is 10.9-11.2 at peak torque

 

Just an opinion, but I would run less timing and lean out the afr in that area. You'd get the torque hit quicker.

 

Hi, here's mine.

I often get 1-2 knock when I goes from nothing to full throttle and boost.
I was wondering if it might be because my transfer from like 100load to 300load(25psi) is to much drastic and that cause my knock sometimes...

What do you think of the map??

 

Kinda high cruise timing, I hope you don't have EGR advance activated.
Kinda harsh from 60 to 160 load, like you said maybe smooth that a little bit.
Other than that it looks good for 93 octane.

 

I did my timing advance like that and dropped it back after a few people brought up the egr method so that it would drive smoother. Less delta t is gonna go from 0-3% tps smoother, and the egr method only adds it in during cruise conditions. Plus there are some other concepts I don't quite understand .

a tad over my head, and did we ever cover how decel timing effects engine braking?

 

Having problems getting my hot start dialed in with the s3s... Tried looking at other maps in this thread for some guidance and it still has trouble finding idle on hot start and when dropping out of gear during cruising. I can't post up timing map at this moment but can later on tonight. Mods are:

9:1 built motor
FP red
PTE 880
GSC s3
Buschur double pumper
Fuel lab AFPR
Full bolt ons

 

I made some reading about this last month. To adjust engine braking, main thing to tune: ISCV. You can make it to stay opened after a WOT, or simply after reaching at certain RPM value. Also, from my testing, to reduce engine braking you add timing, and fuel. To have more engine braking, you go leaner and weaker timing (less torque) (the latter only work with fuel injected / part throttle)

All cases have their limits which when you cross them, you fall in a badly tuned behavior.

 

Macaroni:::

Sounds like iscv settings or biss. Do you have stock pcv system aswell?

 

Pcv is deleted. Haven't messed with biss yet but did tinker with iscv

 

Stock pcv helps idle, biss is the best start go back to stock iscv settings If you do biss( just to start fresh )

 

Ill try that out tonight

 

Thats a good map for 25psi. I would run less cruise timing (37-38) and run a little bit more timing from 100-160/180.

Also what are you registering for knock voltage? Sometimes the knock sensor has to be adjusted once the car is modded.

 

I've heard this but also heard the competing argument that it's impossible to tell unless you log knock base and knock adc with high enough sampling rate to see when knock base is exceeded.
