Hi

Im converting my VW 1.8T AGU me3.8.2 to the later ME7.5 management and I was wondering what ecu is best to go for in terms of tuning.  A few people have said they are all the same, but is there any part numbers out there for me7.5 that give better options when mapping?

I just want the buy the better ECU to begin with and not something thats not as good as another.

From my experience, the BAM from the s3 or TT are the best. Main reason is there are complete winols files and xdf's . But as said any me7.5 will do. The 06a906032hn and HJ are just as good you a little work you can flash BAM files onto hem and can be picked up for 1/2 the cost of the BAM . If you go for the HJ then there's the multimap switching file on here as well

Thanks for the reply.

The map switching sounds like something good. I was planning on running the exhaust gas temps through the ecu anyhow and heard the BAM maps can easily be put onto them.

How does the map switching work?  Does it take over from the cruise control?

Chris

Any PCB version will work, best one which will allow you to run any map combination will be the  1 268 318734-9  3.2WH found in the AMK & BAM engines.

How you mean by any map combination nick?  Is that 2 maps for say cruising and one for 'race mode'?

Ill just get a AMK ECU and be done. :)

Hi ,

Do you then simply need to wire in the EGT sensor to the HN/HJ ecu ? ?

Hi friend do you have some updates in your ECU upgrade idea? Do you use the DBC or DBW throttle body? How do you adapt the M7.5 to the sensors?
I was thinking in the same idea in the past. I think that Audi do that in the past with some A3 models. In my country I found some 8L Audi A3 models years up to 2005 with old AGU engine but with Motronic ME7.5 Ecu. Then it should be possible.

Any WIDEBAND ecu, Ones out of AUM TT's seem to get preference.

I understand your idea, but what about the throttle body and VVT solenoid? Wideband O2 sensor can be connected easily but I think that DBW throttle body and VVT solenoid are immerse in the ME7.5 programming, do you understand me?

At the moment i think APX or BAM Ecu/Software are the best ones. But im a starter and theses are just my 2 cents...

APX:
- SAI
- no VVT
- no EGT
- only one O2 Sensor

BAM:
- SAI
- VVT
- EGT
- 2 O2 Sensors
- Ecu is using the EGT Signal

Im running a AGU with K04 at the moment and looking forward to upgrade to Me7.5 too

But APX one uses electric throttle body? is it wideband?

okay good hint...

Apx is indeed narrowband.

BAM/AMK allways has electric throttle body

What about APY?

There is no drive by cable ME7 AFAIK. Not on any production cars at least.
The entire torque model would be completely useless then, and that's the heart of ME7.

I think that exist some cars around there that comes from factory with ME7, wide or narrow band O2 sensors, VVT or non-VVT but with DBC throttle body.  Those ECUs would be the best options for the upgrade.

And I think you are wrong. Any ME7 factory car is going to have a DBW throttle.
If it has a DBC throttle then it will me M5.x or M3.x.

They do exist but they're called MP7.x. Used on PSA like shitroen and peugeot. Entirely ME7 inside except for lack of an electronic throttle control of course.

Yes, but they are not ME7.
The name "ME" means that an electronic throttle is used... thus all my comments.

My last comment was about VAG - I don't believe any VAG cars use MP7 either...
I have no experience with PSA, so I can't comment on that.

If memory serves, there are some small engines like 1.0 polo or so, that use MP7... but it's too far behind for me to remember exactly :)

Went for a 018 H 0261 206 795 Audi TT BAM ecu in the end.  No particular reason about from boasting rights about being BAM ahhaa.

Going to be using it on a GTX3071r 1825cc lump fuly forged, supertech valves etc.... AGU head with none of the VVT, SAI, and other crap on it.....so going to have to get them VVT/SAI coded out.....and hope that no VVT isnt going to play havoc?  Anyone had any experience of this and is it easy to do?

Also think ill be running stock BAM injectors and just flat line my boost table at 5psi or something while the car is run in before I can take it to my mapper.  Any potential issues here?

WG spring at 5psi?

You can run the 018CB file on the 018h ECU, there is a fully defined winols file on here along with an .xdf I did if you wan to use tunerpro. You can then disable everything and anything.

No vvt is fine, just ensure the kfzw maps are the same for 1/2 and also set cdnws to 0 and set the cam switch table to 18 and you won't get the MAF step at what would have been cam change .

JUst picked it up there...shame its not in english ahaha.

Bit of a change of plan for me.  Going to be running a k03s on the 018H ECU.

Struggling to find a map pack for it, however understand the 018CB pack works, however offsets are slightly different.  is that something to worry about?

Ill be disabling sai, N249, VVT, second lambda and a couple other things to begin with, I just want a map pack I know I can use without issue in doing the adjustments.

Ill be using tunerpro mainly so I can get the checksums working properly.

Bit of a newbie to all this so please understand :D

Just flash the CB onto the H Ecu. It'll run fine then you can use the definition files available to map.

Like littco said, use the well defined CB flash. If you need help disabling components not natively installed on your car, I can point you towards the correct ESKONF changes :)

Cheers guys :)

Be needing a few things off, basically running a BAM engine on a AGU hardware setup.  Bit confusing.

I have no need for:

SAI
EVAP
N249
2nd lambda
VVT for now until I get a VVT tensioner

I believe most of them are in the S4 wiki.

I have also got 82mm pistons instead of 81mm, which increased cylinder capacity by 45cc to 1825cc in total....Is there anything I have to change as I guess the engine will make more load due to higher capacity.

Just want to 'learn the ropes' of tuning engines.  Ive done the hardware side so thought id have a look at software :D
