Do you have TGV deletes? If not you'd want to plug it in to ensure they are opening?

Ringland anyone?
Gave the car a clean after over two months of not being driven. Is good to see it looking great again.
Definitely seems like an air leak issue. Will have to either get out some compressed air and fill the manifold or otherwise the soapy water trick. Given it is a vacuum leak I think the idea of putting air in through one of the vaccuum lines with the intake blocked should work best by listening for the leaking air. I am really hoping that it is not the o-ring seals within the zerolift TGVs. Last edited by Kremer930; 30-09-2015 at 06:14 AM. |

Tried to find my boost leak this morning. Couldn't find anything obvious. Instead unplugged the fuel pressure solenoid valve etc and tried to ensure it was correctly plumbed. After pulling it out o realized that I couldn't find clear instructions on how to reassemble it.
I think that I got it though as I now have -16 instead of -5 idle vacuum. Mao also played around with some idle settings for me. We ended up raising the idle speed to 1000rpm which seems to have smoothed a lot of it out. I will now start accumulating the break in kms and some logging. Once I get over 750kms or so I will start bringing in some boost. It is funny hearing the big turbo whine even though I am barely establishing positive pressure and staying below 3500rpm. On the topic for fuel pumps, I notice that my tuner has set the base fuel pressure at 45.1. Whilst it is at 100% on start up the idle is very smooth. Once it drops then the idle roughens up slightly. |

45 is fine for base fuel pressure. supposed to be 43.5. but its so close anyways.

I was talking pump duty cycle. Base fuel pressure is 3 bar which is the same as 43.5psi.

Did a first oil change this morning and purged an air pocket out of the cooling system. Pretty sure I have got it cleared now. The gurgling sounds after driving are gone also.
Vacuum at idle is minus 16-17. Not far off stock but my idle is still lumpy and when driving the computer struggles to catch the idle and it occasionally stalls. AFRs look fine. I am still driving slowly and only using up to 3500rpm. It accelerates smoothly and decelerates smoothly. Transition on small throttle openings generates minor hesitations. I am hoping to have it checked out and resolved over the next week so that I can begin upping the load. |

I have had another strange and unexpected challenge. I have been unable to connect the tactrix for logging with RomRaider.
Learning view and ECUflash connect and work normally but when trying to connect with Romraider the computer gets locked in a cycle of trying to connect and failing at a fast rate. I suspect that this is due to needing to patch the rom to enable extended CAN parameters. Hopefully this is the issue. Quite strange that I have not encountered this challenge before. |

Was an easy fix. Open up the Rom and enable the tick box for extended parameter CAN logging and then save and upload to ECU. All working now as far as logging goes.

Next issue is that removal of the air pump and associated hardware has meant that a barometric sensor contained within the RH side solenoid has been removed.
There are various opinions around as to the requirement to run this sensor but without it the ECU thinks it is operating at around 160m below sea level. I am considering wether to wire in a resistor of 190k ohm or remove the sensor from the solenoid and plug it it. The symptoms of a rough idle match what I am currently dealing with. My tuner raised the question as soon as he saw my initial logs. |
