You don't have to modify anything, it meets all the correct calibrations of the ahu (pump/crank sensor/mk4-n75/mk3-maf, etc). Of course you can pump it up for more power if desired. I used this for stage 6 (6000 rpm) tuning with heavy mods/fuel/boost, with great success. The oem 021GH also needs immo removed. Your tuner should be able to do this or send it to me for a small fee. I spent many hours/years researching every ecu produced for every combination of tdi ever manufactured. I literally have boxes of these ecu's here from R&D. The work has already been done for you.

Could I not grab the 021GH dump from here http://www.chip-tuner.hu/original_ecu_files/files/VW/
and use that with my current ecu or is that out of the question? Because If I had to get a new ecu I'd just go the alh rout with what I have here.

You really need matching firmware (eep & flash) components if you want pinouts/IO to work properly. Otherwise problems arise with mix/match eeprom with non-matching flash can become corrupt (memory error fault), and leave you stranded with bricked ecu.

Yes, yes you can. I need to cull their site again to see if they added anything new. I spotted about a dozen ECU dumps that run on the MSA15.5, and the GH one is commonplace.
If memory serves, all of those will boot on a FA ECU for what it is worth.

028906021JQKind of interesting little thing I've noticed awhile, but never seen anyone else comment on in the timing maps:
At low fueling, high revs, and low temperature you get a lot of advance, enough that the engine is running against itself fairly hard. This says that VW intended the (using old mechanical governor terminology here) "high idle" throttle position to be better usable for warmup. Your high idle being the max no load engine speed.
Does anyone here follow the hints of their engineering and toss a brick on the accelerator while leaving the car to warm up?

I've noticed that too.. I don't think the timing limiter will allow that much timing though. The stock GN file maxes out at 1560 while the cold maps request over 20 degrees up high

This has been brought up before, but I didn't see a clear answer. I am putting a he221 on my ALH and it is going in a MK2. I want to avoid as much electronic control of that turbo as possible, so how would I best tune the N75 out of the file. I am using EDC15suite.

Download an SDI flash file and either edit that to your desired use, or use that to learn what would need to be done.

I am a bit concerned with using a file from another ECU on mine, but I think I can apply what I see in these to my virgin file.
My concern with flashing is that there may be something in the background that references differently, but this may not be the case.
I read that AGR may be the way to go, but SDI is interesting because I can then just give it boost even though it isn't technically expecting it.... Hmmm

It will have a lot of other bytes and switches (undefined in edcsuite) that turn off a lot of the behaviors.
Its not necessarily the maps that control behavior.
EDC Suite barely scratches the surface.
If I was doing this, I would have backups of my original files, including eeprom backup, then convert to a different software version, probably the SDI. People do this to get the "ASV" tune, so it wouldn't be any different.
Then I would tune the fueling maps in the SDI file to my needs.

I have two - both 121 pin, one from an auto and one from a manual. I will have to check PN when I get home from work.
If I backup (which I have done already, need to backup the eeprom however) and then flash a complete new software over, it should bring all of the background data with it if I am thinking about it correctly. It is an erase and reflash situation, correct?
EDC Suite doesn't touch a lot of the stuff that I don't necessarily want to mess with. I may want to disable some error codes but other than that, I think it should do the trick, unless I can't do what I need to for this software version switch.
delete fault codes for under/overboost, and n75 valve fault codes
or at least that's how I did it, in order to keep it trying its best to operate the n75

Kerma - Both of the ECU's I have are 012 CP, which means 2000/2001. This is good for me from a swap standpoint and also from a tuning standpoint I think.

I have right now a standard ALH 10mm pump, but with changed element to 11mm, I was wondering if I change my camplate to DE143, will I have the same fuel flow like on AXG engine?
I mean so pump voltage map and SOI maps corresponds 1:1.

Thanks for answer. I'm with DLC 1019, they are rated for 0.216um.
Right now my pump got problem and we purchased parts to fix it, one of the parts is camplate DE143. My Pump already got the 11mm element, but with the standard camplate DE110.
This is why I think I can get now the pump voltage and SOI map from AXG or AEL.

Hi,
Has anyone used this tool to turn off the EGR valve?
Mine is getting clogged and triggering a warning.
So I thought instead of deleting the EGR valve mechanically I would try using software?
This is a long thread so I a may have missed it.

Yes, but not on an MK5

Can I assume that you used the software on a 2003 jetta DTI ?
No matter what car, what hardware did you use to connect the software to the OBD2?

I used this software for a while on my 2003 TDI with the ALH engine, and EDC15V ecu, yes.
I used an MPPS V13 interface to read the flash data.

The car does matter, since this software only works with edc15 files.. Anything newer than an ALH in North America you'll need different software to do what you want to do. The cable mentioned also doesn't work with a lot of the newer ecus

My car is a BKD golf Mkv.
New to this stuff that talks about files I thought diagnostic systems had the facility to make changes directly to the ECU?
What I don't understand is where you are getting the files from.
I would assume that you connect your laptop to the ODB2 via some black box that mediates between the two system computer and car.
You then download the current data from the ECU to a backup file (so that if stuff goes wrong you can upload it back to the ECU).
Then you manipulate/make changes to the file and then upload the changes back to the ECU.
Is that how it works?
Can you point me to a primer/dummies guide?

BKD is EDC16. So, no the flash editing program, EDC15 Suite, will not work for you.
MPPSv13 reads and writes EDC16 just fine, but there are a lot of options out there.
And yes, you use the cable to read the ECU data, it gives you a hexadecimal file out. Then you make your changes to it (the hard part), and you write the changed file back.
You do not use another car's files, and you definitely do not flash something found on the web.
It's possible to cause severe engine damage.

hi!
does anyone know how to turn on the cruise control light?
I have a golf iv can-bus (tdi ahf 08/'99) ... I had tacho vdo immo2 always can bus and comfort 1j0 ... I have passed tacho vdo immo3 and comfort 1c0 with attached control unit ... everything works except the cruise control light ... someone knows what check to activate it? cruise control it work, but don't cruise control light
I asked around ... and it seems like an ecu mapping problem ... someone is and how to change the map for far to light the cruise light?

My stock ALH has stock cruise control, never had a light in the cluster, but it works..
Also, I think I have asked this around here already, sorry if its a repeat question..
I have remaped my ALH myself, its going strong for almost 20k km's, but when I was learning how to do so, I saw that the ASV engine as a much bigger smoke limiter map, and I would like to cross-flash my ALH ecu with an ASV bin, some say that it works, some say that it bricks the ECU, some said that some numbers on the ECU must be the same, I went searching around on ebay for ECU's and they seem to match, anyone knows if this is possible?
Best regards.
