narrowband to wideband

-vdub- · #1 (**permalink**) 02-21-2013, 05:44 PM

im in the process of figuring out how to do a narrowband to wideband ecu swap. and ive ran into a couple problems. i was told that with vagcom i can rewrite an automatic ecu to work on a manual 1.8t. but im not sure of that. and also i cant find any sort of a wiring diagram that shows which wires i need to add and what not into the ecu plug

IF you don't mind me what is the point of swapping over?

eurodyne isnt compatible with narrowband ecu's. otherwise i wouldnt give a shit lol.

lol makes sense I honestly didn't know anything about the swap i wasn't being a smart ass or anything.

no one seems to know anything about it. ive found one diy and it has no pics, which make it basically useless. i have a basic idea of what needs done. but ive been talking with chris green at usp motorsports and he said he'll charge 3 hours labor to do it for me. so i may just go that route. any clue about being able to recode an auto ecu to manual on vagcom?

Hope this helps

chris said he was going to look into it for me, hes never done it, but if its possible i feel confident he would be able to. sounds a little controversial in that thread but it does seem like theres some valid info that says its possible

it can be done.
all that is basically coding inside the ecu.
to re-write it you basically wipe out the ecu completely.
you then must enter codes in certain orders.
i mean all the coding. not just the trans codes. literally everything.
only then. will it work. and if you mess up one number.. one character.. or just simply the order.. it will not work.

thats the only way i know of to do it. ive personally havent done it.. But.. ive been toying with the idea of doing it and selling coded manual (automatic) ecus. for that exact reason.

That would be a pain in the ass. Which is why I'm going to pay usp to do it, I just want to make sure it's possible for myself and then give them whatever info I can about it. I just don't have the time to deal with it and I need it done like yesterday lol. But thanks for the info

I'm gonna keep everything updated with how it goes so someone else can just search for it.

The thread on vortex seems to say that if I have the skc (secret key code) the recoding could be done with just the transmission codes being changed without having to wipe the whole thing clean
