VW 2.0l(2E) Carb to FI conversion

VW 2.0l(2E) Carb to FI conversion
Last year I had my 2.1 motor replace vir a 2e 2.0l Golf motor. I did not have a lot of money so had to opt
for a cheaper option. Francois in Uitenhage helped me a lot by doing the conversion within my budget. I had to go
with a carburetor instead of FI to keep costs down.

This year I decided to investigate the FI options available.

This thread will document my conversion as well as info on what I needed, where I got it, experiences ,etc.

As far as I can I always try and support the forum members, "Syncro Guys". We need them and hopefully they need our support.

I hope you find this thread useful.


PS... I'm a little behind in starting this thread, so some off my experiences will be back dated.

Re: 2.0l Golf Carb to FI conversion
OK, about 2 months ago I started to look into the different FI systems that are available in SA.
In short, I could either go Digifant(use the old 2.1 FI), aftermarket systems like Gotech or Dictator and then the VW MP9 system.

I did not want to struggle with the 2.1 electronics anymore as 2nd hand parts are becoming scarce. So the Digifant system fell out pretty
early in the race.

So, aftermarket FI or MP9 it will be.

Ok, here is the kit that I needed.

Aftermarket FI: ECU unit, wiring harness, Intake manifold, Throttle body switch, Fuel rail, high pressure fuel pump, coil, distributor. Any small parts like gaskets and fittings to allow the above parts to be assembled properly.

MP9 : ECU- mapped for 2.0l, wiring harness, Intake manifold, Fuel rail, MAP sensor, Knock sensor, high pressure pump, coil and distributor. Also throttle body gasket and small parts to make sure every thing works together.

Most of the guys prices were the same, give or take a couple of hundred rand, just make sure what you get.

Aftermarket complete go for around R5000 and MP9 between R5000 and R6000.

Re: VW 2.0l(2E) Carb to FI conversion
I ended up buying a MP9 setup from a forum vendor.

I got a Intake manifold, fuel rail, injectors, throttle body, MAP sensor, Wiring harness, ECU, coil, pump and knock sensor.

The manifold did not fit on my exhaust manifold but I managed to swop it out with one I got from Stuart.

I finally got to fit the setup during the week.

Re: VW 2.0l(2E) Carb to FI conversion
The engine started up on the 3rd swing.

I took it to Francois in Uitenhage to tune and so far no joy.
The engine starts fine but idles with a miss and runs very badly.

It has almost no power. If I open the throttle just a bit the revs drop instead of picking up.

If I had to explain it to someone I'd have to say the timing is out.
Ian also had a look and no luck.

I've swopped out the coil and tci, replaced the plugleads and distributor with new ones..... still no luck.
I even removed the alarm/immobilizer encase it had something to do with it.

So, any ideas. All I can think of is to get another ECU and harness and try that to.

Can the injectors cause this?

It is very frustrating. Please help guys.

Did you replace the distributor now or just the distributor cap?

hi Herman

sounds like the timing is out. call me and i will explain how to get it set correctly on the Mp9 set up. best is to be at the bust at the time should take about 5 mins to sort out.

stuart

I may be a mechanic, but i can't fix stupid

Re: VW 2.0l(2E) Carb to FI conversion
Aaaa... no joy yet. Thanks Stuart, I appreciate your help after hours.

I checked the injectors by unclipping them 1 at a time and checking, but they all seem fine.
I also double checked timing marks on the crank and cam shaft. Then I set the dizzy up as Stuart
explained over the phone. No change what so ever.

I don't know how exactly the throttle body works, but it does sound noisy\rattling at idle.

I'm open to any suggestions, I've got notting left to swop out or check.

Re: VW 2.0l(2E) Carb to FI conversion
just gonna start mentioning random stuff now coz you are stuck

is there a vacuum pipe on the fuel pressure valve on the fuel rail ?
Have you tried to bleed the fuel rail by taking the out line off and letting the pump run for a bit

try to unplug components and see if it doesnt make things worse, like the throttle body and air flow sensor

is exhaust not blocked by any chance ?

will post more suggestions when i think of them

it will get sorted out, man always wins over machine
