Hey Everyone. Today we are doing something a bit new. I've been planning to swap the TT turbo out for a while, and with the help of Motoza we are taking our first step towards doing that. The early model 1.8T's came with a narrowband AFR setup. While this is functional, the later models came with a wideband version which supported much better fuel control, MPG, and overall tuning ability. Today we are going to swap the older TT to support wideband, and it's going to be a fun project.
NOTE: I flipped the two Ecu pins by accident. The black wire goes to 72. and the Brown wire goes to 52. Easy fix thankfully.
Huge shoutout to Motoza for helping with all of this! Definitely check them out for any tuning needs you have: motozaperformance.com/
Send them an email if you're interested in one of these harnesses.
Thank you for watching, Consider liking and subscribing for more.

I found out a little later that I had the two ECU pins flipped. The corrected order is in the description:)

Good video!

That’s funny. When I hooked up mine from carrot top tuning I had to switch mine also 😅😅. Ps tho you could have used ur WB ecu and drove with it as long as engine is similar mines running an untuned WB Passat ecu on a b5a4. It works nice and the only check engine light that’s on is for the VVT. But no signs of limp or anything and there’s even more power since the boost is bumped up from 8psi to 10 but still not a bad idea to do what you did. I’m sure the motoza tune deleted the vvt so no more codes for that whole system 😅😅

Great video as always, stoked to see this build progressing. I felt inspired and did some googling, turns out my 1.8T is already wideband. Pleasant surprise for sure.

@HunterDirection Год назад

Haha that's great! Saves you the conversion process! Thank you for the support.

Hey thank you Andy! I really appreciate that.

I can really recommend Motoza, I am in the process of tuning my S4 B5 and their knowledge and their service is one of a kind. I'm super happy with Motoza so far and it's actually through your channel that I found Motoza :)

Good video bud. Well edited and informative. Thanks for the help. I’ll be doing this on my beetle 🤘

Thanks for the video man. I got my first euro about a year ago (a B5 A4) and I've been loving it, but it's a narrowband AEB. Great internals at least! I'm just now learning about tuning/computers so this video was a lot of help to me.

@f.a3202 Месяц назад

I have the same car and i wanna tune it. Did you do a wideband conversion on yours? If yes what did you need to change

@joshuawilcox1322 Месяц назад

@@f.a3202 I have not yet, after some more research I found it's a bigger job than I thought it was. You'll need an engine harness, ECU, O2 sensor, body harness, electronic throttle body/pedal, and a few others. I did find a company that is able to tune these, either you send them your ECU or they send you one for an extra $50. They're called ECAConcepts.

@joshuawilcox1322 Месяц назад

@@f.a3202 I have not yet. ECAConcepts does tune these cars though, even with Narrowband!

@lilsleepy4life Год назад

One thing about this setup you can go mafless. :) I already have my setup for wideband. I have a BEA ECU from an 04 TT. Got my conversion kit from carrot top tuning. Got my Wideband off amazon. All I'm doing now is waiting for my connector rod, bearings and pistons so i can do it all at once. Big power big gains!!!

@HunterDirection Год назад

Oh that's really cool. Not having to worry about maf wiring helps a ton when putting together a turbo kit. Sounds like your car is gonna be a blast!

@lilsleepy4life Год назад

@@HunterDirection I'm just wishing the best of my TT bro. I'm not heavily modded like you just yet. I have everything to go stage 2 tune (currently on stage 1+). But when I'm done with the engine build and supporting mods to handle a stage 3 tune I will be happy. I saw your FMIC vid. Did you removed the headlight washers or you kept them?

@KurruptedDataYouT Год назад

@cmidas3396 Год назад

Hey great video bro. I'm literally in the middle of doing this myself. Not sure if I'm gonna film it for my channel though because of time constraints. Just recently came across your channel and you give great narration and direction. I also have a C5 stage3 2.7t Allroad and my TT is an 02 so maybe great minds think alike lol. Anyways keep up the good work and content, subscribed👍

@@HunterDirection Yes,Sir lol. FYI get the grams throttle body. Night & day difference. I should be ready for my Motoza tune this week. Can't wait to see how it performs.

@HunterDirection Год назад

@@cmidas3396yeah I've been looking at that throttle body alot. You had to DIY the intercooler pipe coming off it yeah?

@cmidas3396 Год назад

@@HunterDirection Yes at the throttle body you'll need a silicone 3" to 2.75" or 2.5" 90 and a 2.75" or 2.5" coupler to connect to your existing intercooler to throttle body hose that you'll need to cut. I got them from amazon prime with overnight delivery.

@izzyauto6298 Год назад

This is awesome. I have a 1.8T Corrado here in Washington and I'm getting ready to drop a later model 225 hp engine and was wondering if I can run the AWP harness with it. I do have Motoza base tune on the AWP engine harness.

@jimakos75 Год назад

Thanks for the video. I want to ask you if i can do the modification you saw us. I have vw golf mk4 gti with agu motor. So throttle cable. Can i buy a ecu and the conversation kit and make it wide band?

@gregr3283 6 месяцев назад

Great video but it would be nice if you mentioned your source for the ECU.

@ziggyortiz37 Год назад

What wideband o2 sensor did u use with the harness I don't know which LSU to use

@trailerparkferraris7969 9 месяцев назад

Did you have any issues with the radiator fans? I have a 2001 Audi TT 225 AMU, I picked up an AWP ecu from a buddy to see if it would work for a wideband conversion. After swapping the AWP ecu in the fans pulsate basically, turn on and off continuously as soon as you turn the ignition on….reading online they say to disconnect white wire/pin #61 from ecu connector. Tried that, fans quit pulsating and turning on with the ignition. But don’t seem to turn on when the car gets up to temp. I’m just curious if you have to move any of the ecu pins around for the conversion? For the fan control module…. I know you have to add the wideband conversion harness into the ecu connectors that’s not an issue. I fully understand that part. If you didn’t have any problems I’m just going to pick up a turbo beetle s ecu because the AWP swap into AMU is just too much of a headache 😂

@jungillestt02 Год назад

I tried getting to my ecu and its in a metal case blocking me from taking it out, kinda annoying. I have the the awp 180, could I do this as well? I need to replace my o2 sensor, spending the 100$ something already kinda sucks haha

@theGinthebuilding 9 месяцев назад

What did you do about the BEA wideband ECU looking for the EGT sensor input that the AMU doesn't have? I haven't found much info on this, the BEA has an exhaust gas temp sensor on the turbo so I figured you'll be getting a code for the EGT no signal?

@f.a3202 Месяц назад

Hello, I have an A4 B5 1997 AEB and i wanna tune it but its narrowband. If i change te ECU what will happen with IMMO? Also do i need to change the throttle body to an electronic one?

@renedewael9703 Год назад

Impressive ! What engine code have you ? APX ? Mine is BAM and I guess it’s wide band. Also, I did’nt see any fixation for the ecu in your vid. How does it sit ?

@HunterDirection Год назад

My engine is an AMU. Also yeah my car doesn't have the typical ecu bracket. Never had it when I picked it up. The ecu slides into some rails in the back and doesn't have much room to move around thankfully.

@renedewael9703 Год назад

@@HunterDirection Ok. So wide band o2 sensor ( on the downpipe ) is a 6 pins connector, and narrow is a 4 pins right ?

@liljoe5063 Год назад

Would you recommend using Motoza over a plug-in-play ecu (like Unitronic or APR)?

@HunterDirection Год назад

I've used Motoza for my past 3 audis and I love them. They offer custom tunes as opposed to off the shelf tunes. That way the tune uses the mods your car has vs generic stages and not really checking how the car responds to the tune. Really good people too. Of the shelf tunes arent bad or anything, but I like the vibe of motoza more personally.

@HunterDirection Год назад

@DustySteel Год назад

I tried contacting Motoza a few years ago for my AEB Audi. They basically told me no lol. So I went with Eurodyne Maestro instead. Does Motoza charge for each flash like most companies? Once I go big turbo though I’m going to switch to Haltech Elite.

@jdh946 Год назад

Likely because most of the early AEB cars ECU's are not flashable over the OBD port. From what I understand you get X number of revisions with your tune through them, you can also purchase more if needed.

@DustySteel Год назад

@@jdh946 so why not have it for the later AEB models that do allow for that? I use the OBD port to connect to my laptop and use Eurodyne Maestro.

@jdh946 Год назад

@@DustySteel My guess would be their flashing software may just not support the earlier ECU's communication protocol or something like that. But you'd need to reach out with your ECU part number and I'm sure they'd give you a solid answer!

@DustySteel Год назад

@@jdh946 I did back in the day after them swearing up and down that they had a tune for it. Gave them my vin and they basically just said sorry. Lame because even APR would allow for the ecu to be sent in for hardwire.
