He needs to do a proper log. He is pedaling up and down. I am almost 100% sure that his tuner did not even touch PID maps at this Point.
The PID maps are stock, i said that in my original post. I pedaled it becuase it spiked the boost guage round to 25psi. Went for it again and then thaught nah this is stupid. |

Files are attached. Original file from the tuner, then v2 is the version i modified to fix FKKVS and some other things. ORI is here: http://nefariousmotorsports.com/forum/index.php?topic=2156.0The original file should have only had the emissions deletes, disabling VVT and EGT, and KRKTE for the injectors. Its not been wildly hacked about with. |

So why is it requesting >10 DC even when actual boost is above requested? |

Exactly as i said. Original PID maps in your case are realy wrong. Needs to be reworked from scratch. I understand why you was pedaling it. See it in your log Botton line dont push it or pull N75 until you get it tuned. |

I dont know, thats what i'm here to find out  I presume its pulling that from IMX and the PID controller cant react fast enough because its so far out? |

Could it be related to the modifying of the axis of KFVPDKSD?
As i mentioned in the OP, the modified axis on KFVPDKSD looks strange. It may be that this file is using the RS4 style CWPLGU = 0
Perhaps thats causing the weirdness?

No, that is in the throttle plate path, not the LDR path, and for a tighter wastegate, that axis change should be fine (and is recommended) What does DRL look like? Is it stock? I dont have a CB kp or xdf so i can't check it myself. |

This is the XDF i have so far. I've been slowly building it up from the OLS on here for the 0002 software revision.
Just added DRL and IMX to it for you.

I'm asking YOU to look at DRL, dont' make me download your file and xdf. At least do some of the work; you'll have to tune DRL at some point anyway. |

ok i can do that.
Can you perhaps explain how the ECU selects an WGDC? I've read the Wiki but cant really figure it out.
I assumed it used IMX, but looking at that table it appears to reference WGDC against ambient pressure? I expected there would be a table of WGDC against boost and rpm? The wiki seems to suggest that IMX should follow the WGDC at WOT? yet in the stock file, its up in the 70-80% range across the board? Does the little 5psi actuator need that much DC to produce 12psi?
Is there some way i can cap maximum WGDC to stop it spiking stupidly while i'm trying to figure out why its running so much WGDC? Theres no way i'm going full throttle again with it in its current state. I like my engine in one piece. If i'm right above, i presume i can limit the top two rows of IMX to say 30%?
Cheers
Kev

ok that IMX axis isnt atmospheric is it? Its boost...
Means it only goes up to 1 bar as stock though?
