Lean at wot

[Ttype6]

i made the base wot 140... seems it didn't work? air/fuel is stilll 10.8 but i never really romped on it

If your target is still 10.8,the computer will do as much as it can to reach the target. In the last file,the richest you got was 11.38 according to what I see on my dash board. Was your WOT fuel set to 128 before you increased it?

 

[TireFryer]

yes it was. on another log i got into 12 psi and it went richer to 10.8... i was only running lowish boost today

 

[Ttype6]

yes it was.

I see that the wot target fuel is activated above 13 psi boost according to Turbotweak.

So im not even getting into the actual "wot" programming of the chip yet

I think you are,but you might not be at the point where the computer adjusts the fuel to hit the WOT fuel target.

Bringing this back up. I did a pull today, and wasn't planning on 20 psi... i was shooting for 14... Anyhow, The car is running great and im just curious to the knock that im getting. I only have 14 degrees of high gear timing in it and a wot afr of 10.6. It almost seems like it knocks when it goes all the way rich? I had the alky running at the default setting of 6 gain. Looks like my blm are quite high, even though fuel pressure is rising 1:1 with boost. Can an overly rich afr cause knock? Can a stock return line with a higher base fp cause knock? I promise i turned the wastegate all the way down and the rjc boost controller to prevent that much boost until im ready. Any help is appreciated.

Here's a video of the run.

What have you got the base fuel pressure set at?

 

[TireFryer]

42# line on.

 

[SCOOBY DOO]

Have you got Erics chip on the default settings?

 

[TireFryer]

No. I have a lot of timing pulled out of it 16 low gear and 14 high gear. other than that its all default. Timing scares me a lot.

 

[SCOOBY DOO]

Reply 120 you said you messed with the fueling in the chip.

 

[TireFryer]

ive had a high wot blm (140) even at default. So i bumped the base wot fuel up to 140 like the instructions say to get it closer to 128. The blm's at idle are 118, guessing because of the high fuel pressure.

 

[SCOOBY DOO]

High fuel pressure? You said it's 42 line off...which is normal.

 

[TireFryer]

its 42 line on. The regualtor would go down to 40 line OFF but there wasnt any preload on the regulator so i raised to 46 line OFF and its at 42 line ON. I'm getting a return line made soon and will set base fp to 42 line OFF

Get the return line on it and retry setting the fuel pressure.
