I have true KR because I drove the $hit out of my car on C16, no KR..help needed

[Toby_Goodmk]

So now I need some KR help with making the knock go away. I didnt think it would be possible to get KR with low boost numbers but I do. I will say running on C16 is fun as hell man.

Can someone look into this log and see what can be done to decrease the KR? In the file at 58 seconds, and 75 seconds is a good picture of the knock I am experiencing.

I have my alky settings set at the preset figures, I would guess I need the turnon to come in earlier and put more initial in as well.

looks lean . A/F is low 13s at 10psi

whats the fuel pressure

 

[Toby_Goodmk]

fuel pressure is in the 50s, in the log it is logged. o2 looks decent??? no maybe so?

 

[pacecarta]

no o2s look lousy , your 15-17 AF early on the hit

 

[Toby_Goodmk]

here is my race gas PL file....

 

[Toby_Goodmk]

no o2s look lousy , your 15-17 AF early on the hit

I just looked at 58 seconds spot on the PL file. WB is 10.5:1, o2 is .858, FB 54lb

We seeing the same file?

look at 19.94 sec frame 320

What wideband for when we look at log?

 

[pacecarta]

you need to log alky pressure , havent tried tuning a hotair but you need a differnt alky curve than we run with an intercooler

 

[pacecarta]

What wideband for when we look at log?

his sig shows AEM wideband

 

[pacecarta]

Toby where is your IAT sensor , seems to be at almost 160 and stays up there while boosting
if it were in the plenum you might be able to log the iat temps after the nozzle and see the alky effect

 

[Toby_Goodmk]

yea I know. I have it in the front near the #1 cylinder. I forget whom recommended that position for me.

 

[pacecarta]

if its that high you need to recurve the alky injection , for intercooled we dont flow much alky at 10psi because there is no real need , see if razor can give any guidance and where to set your dials in the pac controller

 

[Toby_Goodmk]

look at 19.94 sec frame 320

I see that now, take a look at 58 and 75 seconds however. It looks a bit more normal. I took the pac controller and moved the turn on to 10:00 and the initial to 2pm

 

[pacecarta]

turn on should be 9:00 or less , mines at 9:00 and comes on at around 7psi

I wish there was a way to view sigs on mobile devices. It comes up a lot

I recommend the iat sensor position.

 

[Toby_Goodmk]

I recommend the iat sensor position.

that is right!! Memory at 40 is not too good anymore

 

[pacecarta]

I recommend the iat sensor position.

thats a good spot for it , i run mine the same place on the 86 , if that cylinder inlet area shows a cooling effect the others should be fine

 

[Toby_Goodmk]

turn on should be 9:00 or less , mines at 9:00 and comes on at around 7psi

mine was coming on about that psi as well, but my turn on was around 1130. Ill kick it back to 930 or 10 and see how things react. But for the meantime I am sure enjoying the race gas and Reed's new 6262 turbo!!!
