What's the difference?
How do I get that screw out?

the screw circled probably doesnt need to be removed, just pull the tin metal clip outwards to release the mk1 plug from the ecu
dont bolt it all back together till you know the mk2 ecu is working, just plug the loom into it and see

When you say tin metal clip, do you mean this?
Is there one of these clips at the other side? Impossible to see.

You can only get to it after you remove the ECU with the Bracket.
Remove the connector.
Remove the screw at the top of the bracket that holds the ecu and bracket at the top of the bracket, then slide the bracket to the right to disengage the assembly off the rain tray….There is a slot on the bottom of the bracket, and a stud on the rain tray that holds the bracket to the tray at the bottom.
Once off, you can then remove the screws that hold the ECU to the bracket.

1st one is for the spark module, push the middle of it towards the plug or up in the photo and the plug pulls off.
remove the ecu brackets as Briano says, unscrew the mk2 ecu from its bracket, grab the spark moduel off it too handy for a sapre.
plug the mk2 ecu in before you swap anything over in case its blown, use the mk1 spark module as known good. see if the car starts, if it does great the mk2 ecu is good. try the mk2 spark module as well, if it still starts great put that in the glovebox as a known good spare. swap mk2 ecu into mk12 bracket, refit bracket and you're good to go

After I have done that, I wonder if I should keep this chipped ECU or send it back and get either a normal ECU, or choose a custom chip for my ECU.

tuning chips though all much of a muchness, that is to say not as brilliant as the marketing would have you believe I've tried several different types in my digifant and non of them really made a massive difference over standard certainly not worth the prices asked for them.
fit the ecu and drive the car, if it feels good then great carry on, dont bother messing about any further

The headers are on opposite ends relative to the mounting holes. Can the chips be swopped over?

When I picked up a spare ecu from the yard (breakers) I noticed this feature, and you can mount the non-cabriolet ECU in the Bracket, but you have to Drill holes in the top, and well dremel them to look nice and you can affix with a good wire tie. It clamps the same but as it isn't really bolted well you have to add a ground to the heat sink to frame, and then the bonding wire at the top.
The heat sink is at Ground for the ECU and so the addition of it is a good thing,,,,
I do think that the "Chip" you show is really a different resistor pack, as that was a common thing a few years ago.
There was a Gentleman from Greece (Black_cabbie) on the VW Vortex that actually had a true Chip that folks raved about but I think either way was 50 to 80 bucks and I thought about it….but decided to go a different route….
I found that increasing the inlet diameter of the air box, removing the Snorkle and re-directing the inflow of air behind the grille, as well as using a K&N air filter vastly improved the throttle feel… But at the same time I Ran a 4-2 manifold and got rid of the cracked single outlet, as well as running a Dual Down Pipe, (removing the cat same for Emission testing once a year). Probably gave me more ponies by the Seat of the Pants Method than a chip ever could…..
I don't know if your MOT would allow moving the intake to the airbox, but well I got good Ram Air into it at 60mph…..
Here is a good how do I do that on increasing the airflow….
http://cabby-info.com/Files/ImprovingAirflow.pdf
Also I took the top off a bottle, might have been Anti-freeze, and Plugged the hot air intake so I could remove the Vacuum assisted servo and plug that line off at the throttle body… I suspect that you can plug it internally with a cap and "silly-cone" and the MOT would probably never find that modification.

the other problem is most of these will only change the fuel map, since the ignition map is on another ecu and this is much harder to change

There is a lot of conflicting information out there. Some say the K&N makes no difference. Some say Pipercross is better. Some say the GTI has a different cam to the 2H. Some say the performance chips make a world of difference, some say they make fire come out of the exhaust.
If it's true that the difference between 2H and PB is simply a cat delete and different ECU, then it's a no brainer for me. The cat is already gone
72 kW (98 PS; 97 hp) at 5400 rpm - 142 N⋅m (105 lb⋅ft) at 3000 rpm
to
82 kW (111 PS; 110 hp) at 5800 rpm - 154 N⋅m (114 lb⋅ft) at 3500 rpm
for £40 and switching a box over.
Did you ever try a PB ECU after your mods, or do you still have the 2H?
I noticed the ground on the ECU bracket you mention. Is it safe to test drive without the heatsink attached to the bracket. I think I will make a plate to adapt the mk1 bracket to the mk2 box.

heres a great thread on the 16v MK3, note this has no big metal flap inside to get in the way of airflow:
https://clubgti.com/forums/index.php?threads/199237
The 2H cam is the same as PB, but its slightly different to a hydralic kjet one and apparently there is a slight benefit to be had. but you could buy a better aftermarket unit to get more out of it.
when it comes to chips look at where the guy is, and if there is any hard evidence showing the benefits claimed. like i say with a pb ecu all you can change really is the fuel map so only small benefits to be had. the ignition map also needs tweaked to get the best and there are very few people left who can do this and likely non of those left can be bothered
the PB ecu has no extra earth wire when fitted in the mk2 and the ecu bracket is also pretty well isolated from earth too as it has no bolts holding it down its just clipped to studs on the car. I mean feel free to add the earth as mentioned but I doubt it will make a difference. I've had mine running with the ecu just floating about in the scuttle when testing and car still ran fine

It idles lower (750rpm). There is more torque, and I wheel spinned by mistake (which I never done before). I got that feeling of being pushed into the seat a bit, once. Overall acceleration is a little better, and it pulls a bit more in the higher gears.
Sadly, accelerating hard in 2nd round a corner caused everything to shudder which reminded me I have to deal with rack and shocks pretty quick.

worth checking the ignition timing, but if it was fine before it should still be fine now

I am also looking for something like he did, a PB ecu for my 2H, fun facts, I have etka online, and I cannot find the ECU 037 906 022 N, and those Ecu's are quite rare in my country, so, I wonder If anyone knows all parts numbers from ECU's from PB that will work on 2H.
On Etka mentions that there are some PB with O2/lambda sensor, but usually everyone says that PB does not have one.

there are several part numbers you can use, tbh the easiest option would probably be try to find one on UK ebay from a seller who can be bothered to post one to you:
maybe get in touch with this guy, he refurbs DFII ECU and if you're going to the trouble of importing one probably a good idea to make sure it'l;l last:

I am aware of the ground strap issues and also the isv issues( if you disconnect the plug with ignition on can harm the ecu).
In my case like many other people, using the GTI ecu is just a "band aid" solution, I cannot tune my ecu on my own(cannot find anyone to do it eather), so I need a good base map and I tweak it with piggy back on temp sensor and air temp sensor, dustributor, not the best solution at all, it has limitations but it works till a certain point.
