I guess only Scanmatik will work in bench... Module 71 is this way

Thanks for the response. I figured it out. I'm an idiot. The "VKEY" wire on the powerbox needed to be connected as well. I did not see that mentioned anywhere. I will leave this thread up in case there are more idiots down the road like me that did not know this.

I guess only Scanmatik will work in bench... Module 71 is this way

Hello, i'm trying to delete rear o2 and sai in my car, i think that i found codewords in wrong places. SAI and cats are ok in readiness but o2 not.
Can somebody help with
CDLSH
CDLATV
CDLASH
CDKAT
CDHSHE
CDHSH

hi mate,
sorry to bump old post i have same ecu trying to off sai from eskonf.
could it be slightly in wrong location with your map pack? I am not sure how to know exactly where it starts and finishes.
maybe someone can help.
TIA

Why is your TVUB not matching the finjector specs you linked to 

Because I received technical data from another vendor.

Now I have tried the data from finjector. These work much better. Thanks for your help.

Thx for the info... I think I understand the load during overrun (but shouldnt the throttle plate be shut tight?), but I also see an injection period of about 1.2ms (which anyway mostly seems to be about double the load), during the whole overrun. It is never zero. I guess this is just some calculated value while real is 0? This is vag-com group 2, "inj. period".

However, back on topic, does anyone understand why "load" is in miliseconds? I would understand if it was related to actual injection time, like a theoretical value or something, but the actual injection period mostly seems to be about double that value. What was the idea behind this? And how to log injection time above 16.32ms?  

One more thing, the ignition table goes only up to 10ms "load", but the ecu allows up to 12.7ms without scaling anything. How is ignition timing calculated beyond 10ms? Does it take the last line or extrapolate?

To answer my own question, yes install it without do anything (just that comes from factory) and works quite good.

Thx a lot
I try it tomorrow

Hey, Just posting here while I wait on a response from support. In case anyone can help.

I am trying to read AL551 TCM Bosch SH725xx with pcmflash module 82

I have Powerbox and genuine openport 2.0 connected to powerbox. This is my first time doing a bench read but I am sure everything is wired correctly and I toggle the 12V on and off when prompted but PCM flash fails to read, itll begin and then after displaying eeprom size itll say completed unsuccessfully. Everytime it fails the tcm makes a noise and the powerbox red "VECU" light starts flickering until I turn it off. I  tried using direct 12V as well in case the powerbox was faulty or not giving enough power but the result was the same.

Previously I tried clone SM2 but had same issues so I purchased genuine openport to use with the powerbox instead but the result is the same. Has anyone had issues using openport 2.0 with powerbox? Is there anything you recommend that I try?

PCMflash support recommended the genuine openport 2.0 to me for this purpose

hello gremlin, thank you for your answer.
I wasn't sure if A4 B5 would start + stall after 3 seconds (I know Golf Mk4 would do so).
Anyway:

I connected the M3.8.2 on the bench, without success.
VCDS shows the identical message like in the car: "ecu doesn't answer"

yet what I noticed:
as soon as I powered up the ECU, there was irregular high frequency noise for 3 to 5 seconds...?
(tried 2 times)

is there a critical chip/component on the pcb, which is known to fail sometimes?
Or is there anything I could notice by visual inspection of the pcb?

As I wrote in the initial post: donor car was up and running with this ECU + harness, except for the fact that I did immo off after the first attempt of firing up didn't work.
symptoms are identical compared to "before immo off" so I don't think it relates to a failed immo off

A question about overrun fuelling (I am actually trying to do the opposite to most people - maximize engine braking capability), why do I see around 0.6ms load during overrun? Even several seconds after releasing the throttle, in a wide range of engine speed. Is this some kind of a bug or does it always fuel on overrun?

Also, I noticed the idle regulation starts at quite high rpm, like 1500 (other cars 1000-1200). I only see a relevant value called NDLSO (obere Drehzahlschwelle für digitale Leerlaufstabilisierung - Upper speed threshold for digital idle stabilization) which reads 1200 and does not seem to reflect reality. What are the relevant maps for overrun fuelling and idle regulation?

Thanks

Hi mate, it's normal to have load on overrun, in the end there is air flowing through the maf... But this does not mean it is doing something with it. If you see TVSAM maps, they are (in theory) the time it stays in idle mode before fuel injection deactivation (overrun function). But with M3.8.3 I havent had much success with the ecu obeying the values in it, nor the idle reinsert speed you mention in your previous post...

With 8D0907558E (chip, M3.8.2) all this maps have worked for me as epxected and always doing everything I modified. So I am a bit doubtful here on what might be different brom M3.8.2 to M3.8.3. I was conducting some investigation with it but had to postpone it a few weeks for work stuff.

I found that 018R software is more responsive to changes than 018AQ, but still not toing 100% what i ask it to do... Lets post here if we do more discoveries.

Best regards
