So i just acquired a 1990 gli with the stock 2.0 16v and is ce2. I read through most of this thread and nowhere did i see any specific info on how to convert a car thats already got the 16v in it. The replies i saw about it just said that ce2 is plug and play. I understand pretty much everything, except for what will plug into the fuel injector harness once i switch everything over. Will i use one of the plugs that went to the fuel dizzy on the stock 16v system? Any insight is appreciated. In the meantime ill keep reading.

Hey guys, I have qestion about digi II. I connect almost all wire, have only one from injections to inside car (red-yellow wire, not from fuel pomp), to what wire from old motronic should I connect this?
On my particular build the exhaust was not at all compatible. Luckily I still had from the cat to the head but the 16v cat out to the cat back is larger than the 8v..
On this particular image, i went the route without the 8v flange.
i like the metal flanges better.
the issue im left with is no where to plug in my AC shut off sensor.
does anyone happen to have a part number to replace #4 with a sensor that is always on unless overheated...
im unsure what its called. i assume thermo switch?
When you cut the black wire connector off and plug the hot wire into #5 should we ground the brown wire?
I could really use some trouble shooting help! Using ce1 and digi II on my 9a 16v, i have power to everything key on, starter cranks and ect. The problem i am having is that i have no signal power from the ECU to the fuel pump relay, the yellow/red wire on pin 13 that powers the relay has no power whats so ever. I can manually energize the relay and fuel pump kicks on... iv tried everything im fully stumped at this point. Any clues would be a big help. Thanks!

Me and you are in the same boat. From what I understand the digi 2 sends a ground signal to the relay. I'm trying to figure out why mine is not coming on.
You folks have a ton of problems with your swaps, jesus, i dropped my engine in, fabbed the intake tube for hte vam, lengthened my harness for the fuel injectors, replaced the ecu i fried... used a blue coolant temp sensor in a flange i bought from the dealer, plugged my gauge for the dash into the stock 16v cts... plugged off half the connectors for vacuum, i took the stock 16v throttle body connector off my motronic harness, made sure the idle and WOT switches grounded on idle and WOT to their respective wires, and had infinite ohms when 1-99% throttle... other thant aht really its such an easy swap and i did it in like 8 hours lol the alternator swap was harder than the engien swap for me... my car idles at 950 rpm, sometimes at 1100 (no isv) ...hits fuel cutoff at about 6750 (Stock) i have a digifast chip... oh ya i also tossed the cold start injector and glued a peice of tin over the hole, i still have the connector for the ISV incase i want to hook it up... so far i havent had troubles starting cold, even with NO O2 sensor... it chugs a bit on start up blub blub blub...missing because its rich then its fine... i have the hose that goes to the airbox going to my beer can to catch blowby and the stock hose is going to the intake... really you can do this swap not hook up the o2 sensor, just make sure the vam and CTS are plugged in...or it wont start
maybe these pics will help
I've been reading through the thread. There is some awesome info here. However, my scenario hasn't quite come up fully here.
Did a 16v digi2 swap in my 92 jetta carat. Having a major cold start issue. Won't idle and stay running. Like a lot of people here I am not running an ISV. Still running a copot. Once its warmed up it seems to run quite a bit better. Still very hesitant though with the throttle response. Can tell im not getting the power I should be getting. ECU is chipped (cant remember the brand) took it apart once and don't remember. I bought the ECU that way. It does back fire occasionally. Really spits and sputters on initial start up and driving until it clears itself out so to speak. Replaced fuel filter recently. Set the copot with multimeter. I am running the blue cts. Not sure if that's my problem or not. maybe its bad idk. Ive read a lot on here about the ISV and issues everyone has had with it. so that could be the culprit too. running scirocco intake and TB. Also not getting a temp reading on the dash. Hopefully ive given enough info to get some advice back. Thanks in advance.
From what the previous owner of the ecu has told me in his words is its stage 1 n/a. I do have another ecu that is chipped for boosted engine for future project
