2.0 16V into a MK4?

[borachris]

I'm considering putting a 2litre 16valve engine(probably a BMN) into my MK4 Bora which is currently an ASZ 130PD.

Main question at the moment is which ECU should I use? The 15 off a MK4 or 16 off the MK5?

What benefits or drawbacks am I likely to encounter from either?

I know I would have issues with the lack of DPF if using the edc16.

Anything else that I should take into consideration when deciding?

I say an EDC-16 just cause it's more advanced. I don't know anything about any of those engines, so I can't comment on anything specific. All I know is newer ECU's are better, i.e. more maps, more refinement, more control, etc. If it's possible to use it, do it. That's my .02.

 

[im570rm]

just turn off dpf from software and you should be fine with edc16

 

[borachris]

Will using the EDC16 give me any benefits over using my current ECU though?

Will I have problems with anything if I use my current EDC15?

I'm also thinking that the 15 will be easier to map better due to tuners having more experiance with it?

if the edc15 will work with the PD elements I see no reason to go for the hasse to implement edc16..

Thats what my wiring/electrical guru told me!

I think it will just make for a simpler conversion!

 

[Piranha]

IMO more ppl have more experiance with the 15, if you can get it to work well easily go for the 15

 

[borachris]

Cheers guys, looks like the sensors are different so I may have to use the EDC16.

 

[Bazmcc]

Chris I think that the 2.0 is so different from our old PDs that the only option would be to use the EDC16, and preferably just swap the whole engine, loom and ecu together.

The experience of mapping won't really be an issue. Lets face it, we've found there to be less and less good tuners around here for custom builds.

Interesting project fitting 2.0 16V TDI, if you decide to go that way Chris.

 

[pobmk4]

Chris if you fit the 2.0 16v engine and use its loom, will the edc15 ecu plug into it!?!?!?

And as you have already said most of the sensor wiring IS different!!

 

[Gavin.NI]

Nutter, just get a 22-60...

 

[ryanp]

16v FTW!!

 

[Rub87]

What sensors are different?

 

[majesty78]

The engine ecu is the smallest problem. The whole CAN Bus is working with a different protocoll, so putting this engine in, will cause so many mal- and disfunctions that you will need a hell of a lot time to solve these. Not a single ecu Hm the car will work anymore if you transplant this engine.
How i know? A friend of mine did such conversion with a BKD engine in a Polo Mk4. He is registered here, his user name is Deus Violenta.

Ask him, if will have plenty of information of whats happened in the 2 years he needed to make it all work like OEM...

It's all under control. Ray will have it wired and working in about 2-3 hours once it's in the bay.

Anyway, as we're all here now, someone get the tea on and we'll have a good old slabber about who we hate at the minute.

 

[Rub87]

you'll regret you took edc16

Hmmm where to start

aha

here's a man with a knowing wink.

YE KNOW TOO MUCH!!!!

 

[Bobby Singh]

If its that much hassle with OEM ecu you could fit a after market item?

 

[Bazmcc]

An aftermarket ECU (is there a tdi aftermarket ecu available?) would be 10 times worse.

 

[Bobby Singh]

Im not sure if its available (i have no experience of this) but if Chris hits a wall it might be a avenue worth exploring.

I though Rory had a dastek on his because his got messed up big time by a certain company??

 

[Bazmcc]

Don't know what he has in now but he had a piggyback system in at one stage that was plugged between a remapped ecu and his wiring loom to add more fuel and boost.

How could it possibly have been a bad thing? It's like getting your car mapped twice. Surely it must have been putting out twice the power of a normal remap????

(it was putting out twice the black and blue smoke anyway).

 

[pobmk4]

LOL @ Baz, yeah it was a dastek unichip (piggyback stylee) dont know how good these things actually are, or how adjustable either!! But he has one and it works!! LOL

 

[turbo johan]

Just take EDC15 and it will all be simple to get it to work.
If you want edc16 think about using USA golf parts.
US golf has BEW with EDC16 right?

Johan

 

[Rub87]

yep, US has pnp loom for edc16 in mk4, altough I don't know if the can protocols will be compatible..

only good thing on edc16 is that it has 3d map for n75 duty limiting

 

[borachris]

Wow its like a uk-mkivs mini meet lol.

Cheers for all the input guys.

Johan, care to explain just how simple you think it would be?

I'm thinking this is going to be to much work to do to a "daily" I can only really have it off the road for a weekend at a time.

Easy enough on the mechanical side but getting everything to communicate and function correctly could be an issue for such a small time frame.

Opinons?

Ruben, care to explain, drop me a PM

Bobby good to see you on here and the other fellow uk-mkivs members we know.

Chris, best way forward is use your existing engine with the EDC15 ECU.
We know you have a good engine, nicely run in. I'm jealous I need to get more miles on mine.

I've got a spare 30k PD head you can have to play with.

Stage approach will be best way. Turbo installed, mapped. Then injectors/nozzles. Head and bottom end modified.

Set yourself a target for bhp you want and stick to it.

I know I know!

You know me I get easily carried away.
