Hi, I have an audi that is getting the secondary air injection faults. Can anyone give me info on how to setup the flasher and use this to code out the CELs.

Hello,
Some time ago I had put a Julie-immobilizer in between this ecu and the car started and drove like 3 weeks then the car stopped.. Start block active. I have another ecu and new Julie immo in between and no result. I readout the actual immo and it seems as if everything has been moved where it should be. With the ecu repaired from the Julie I can not get communication with vcds. File in attachement. Does anyone know the solution? Or has this happened before? |

Are you sure your DC measuring system is correct? I am moving 170g/s air at 6200rpm and I have no symptoms of running lean with stock injectors (A4 with 4bar fpr so same flow as yours). Yes I am, I work with electronics so I know what I am doing... I actually had two circuits, one which displayed a value directly, and another one which lights up an LED if the IDC is above 97%, so it does not distract me from driving at high speeds. Both were consistent. I reliably hit 100% above 4500rpm and compared this with logs I was doing simultaneously. The 140g/s figure at which this happens was replicated more times.How are you sure about "not running lean"? I also had no "symptoms" at 170g/s, but I don't have a wideband so don't know... Also, there are still mixed signals about stock injector size on the AGU. Actually I found 4 values - 205, 240, 270 and 285cc... Could this be manufacturer specific? Guess I will have to take a look at them directly  btw, is the OEM fuel pump fine with 4bar FPR? From what I found, it most likely is... |

Well, not sure if this is much OT, but I hope not. I did a bit more investigation into the injectors. I measure duty cycle directly on one of them. They consistently max out (100% IDC) at 140g/s, 4500rpm, 10ms "load".  At these conditions, the fuel enrichment according to KFLF i 1.29, which should translate to 11.4 AFR, so 12.3 g/s fuel. For one injector this is 185g/min. Hmm, actually this is close to what marantz posted, a bit on the low side. If they max out at 140g/s, it looks like running 170g/s is asking for trouble. This looks like a job for 4bar FPR even for "stage 1"...Are you sure your DC measuring system is correct?

Hi everyone, just want to say hi from Indonesia. I own a 2014 VW Golf MK7 GTI, I'm currently learning to tune my car myself. Hope can contribute here as well.

Here they agree they are 285cc on AGU... https://www.vwclub.co.za/forum/viewtopic.php?t=178242 My bad I was confused with A4 AEB injectors, although the data on my memory or that forum isn't precise either: 1g/min = 1,39cc/min AGU - 06a906031 - 0280150464 - 194g/min @3bar or 270cc/min @3bar AEB - 058133551 - 0280150447 - 168g/min @3bar or 234cc/min @3bar Considering AEB has 4bar FPR, that pumps AEB injector output to 270cc/min @4bar. I use this calculator for FPR changes: https://raceworks.com.au/calculators/injector-flow-vs-fuel-pressure/ Hence, I was remembering correctly they had the same flow but incorrect on the precise data hah. I belive it isn't that bad to max out the injectors while they are available to provide enough fuel for the air entering the engine, you only have to see how many 1.8t's with stage 1 are running worldwide and not dying. But I am the kind of person that prefers to leave headroom when upgrading them. I use the rule of 100cc more than expected hp. Best regards, |
