My V8 into an A4 like everyone else is now doing...build thread

[pee quu]

very interesting. You are the third person I heard had some odd issues after they had their car tuned from DAZ. I had an issue with a cluster he replaced a screen in for me. Fix to that was getting my money back and having someone else fix it for me

The issue with the 2002+ ecu I heard doenst matter if the file was changed I have a 2003 ecu and it works fine in my v8 it was tuned by breakout motorsports

I just find it weird you had such an issue. My car is 2000 1.8t and the S6 motor is a 2002. All I did was have the immobilizer deleted alone with some emissions things and it worked fine

I want to try this conversion so badly

It's really easy with the right car/ecu/harness

There is no "trying" you either commit to doing it or commit to not doing it lmao. But its true its really not hard, just do your homework with the car you have and the motor you are putting in it

For sure. Like surfing. You either go for it or let someone else do it.

My B6 already has the 2.7 conversion which is fun as fuck, but I love the idea of a nice V8 and the sound.

I just got mine back out from my being at my buddys garage all winter, Its great to drive it again. Its not the fastest but it gets the job done and sounds great doing it lol. The 2.7 in a B6 seems to be the new hot swap. It seems v8s in B5s got popular and than faded off

It happens. Sound clip of yours would be appreciated.

I for one I'm trying to maintain less. So the V8 idea appeals to me because there's less hoses and boost issues to deal with, but that comes with other maintenance as well. The sound of the V8 though.

thats very strange, Daz was very clear that only 01 build ecu running 7.1.1 would work due to full CAN integration in 2002 and using wheel speed sensors instead of a trans mounted vss. I would love to look at the breakout tune and see how its setup. i tried contacting them on multiple occasions but never got a reply

sound clips can be found on my ig mr__pq

My thoughts exactly as far as maintenance goes. I got an upper and lower rad hose and the two hoses to the heater core and one vac line. its as stripped down as it can be. I love it. Once you do the timing belt on the motor its good to go

[spinnin_four]

who else is running a Daz S6 tune? id love to compare and see if/what any differences are

[pee quu]

I don't have a tune on mine. Just emissions stuff deleted. I would like to experience a b5 with a tuned 4.2 but I don't know anyone remotely close with this swap lol

That seems like a decent setup. I like the idea of the motor in a B6 as well. The sound alone is worth it and being able to match a stage 2 2.7tt in power while being naturally aspirated makes sense to me. The issue for me is finding the donor motor wiring and Ecu setup.

it will keep up with a stage 2 2.7t? I have never run one so I couldn't tell you. I mean the s6 4.2 is quick but I didn't think it was that quick. I mean I guess it would even out depending on whos driving. 340hp with a tune vs 320-340hp 2.7 I guess is about even. those are numbers to the crank not the wheels and I'm sure the higher mileage motors have a few horses missing at this point

I'll vouch for commitment! I've found that yea the work is pretty straightforward but finding time -especially with a growing family- can be the hard part! I think I got 50% of my work done in the first month, and the other 50% spread across the last year and a half! Mapping, double checking, and performing wiring changes seems to be the most meticulous. Especially with my half-breed 99.5. Bentley books are wrong or contradicting in many cases.

who else is running a Daz S6 tune? id love to compare and see if/what any differences are

I am getting close to having things running with the stock A6 ART 560AE ECM. Then when I'm sure I have all the kinks figured out I think I will try placing the DAZ tune I have in the spare 559E ECM I bought earlier.
Earlier last year I reached out to someone on nefmoto to find this tune. I was given an "S6_Manual_559E_fixed.bin". Is this the one (at least, filename) you already have? If you would like I can IM you this file to compare.

[haliceaa4]

I guess the guy who owns breakout is away on a sailing trip from what I know I think he tunes out of his home garage I believe it's just him that may be why he hasn't responded not sure how long you have been trying.

I have yet to race anyone which is disappointing... I would like to see how it compares to another vehicle. On breakouts dyno with his v8 the tune was rated for 277hp at 282ft-lbs for the ART engine.

But the thing pulls pretty good.

It also has launch control although I didn't use it on the video I'm worried I'll break something it set for like 5k

In the video I took off slow and it was consistently picking up speed no lag straight pull..

277hp on a regular 4.2 , non s6? Does anyone know what the stock HP to the wheels is on that motor being the tune is only rated at 277hp? That motor stock is supposed to be 300hp to the crank

[pee quu]

...it was consistently picking up speed no lag straight pull..

That has got to be one of my favorite things about the 4.2. No matter how fast you are going and no matter what gear, you put your foot down and it just pulls and keeps pulling. There is a never a feeling of it hitting a point and it flattens out. it just keeps going. you can be cruising in 6th, for thiose with 6 speeds, put you foot to the floor and it takes off with out having to down shift

[haliceaa4]

On a regular 4.2 yes. Stock wheel hp is somewhere in the mid 200s

Sent from my SM-G930P using Tapatalk

[pee quu]

So the tune is giving you like 50hp give or take. Not bad for a NA motor

[haliceaa4]

Im not sure but I don't think it's that much my guess would be 260ish wheel but I'm no expert

No joke here I only have a 5spd. My gf says it makes her stomach drop lol

So, i was contacted my Mirza from Boosted Euro. apparently he has written a complete from scratch tune for the 4.2, his setup dynoed 290 awhp. I have been talking to him on FB and i will be sending my ECU for him to flash next week. basically, his tune corrects all the rev hang and idle hunt issues associated with running a automatic file. fixes the vss issue i was having in Daz tune, has launch control etc. and smooths out drivability and the intake change over dips that occur in the stock file. He seemed very knowledgeable, i will report back with the results asap. i am trying to get on a dyno this weekend to baseline where i am at with a stock a6 file as a starting point.

Wow. Very interested to see the results. If all yields well I might to get his contact info from you and what he charges..

Interesting results...

...personally, to avoid all these issues - idle, rev hang etc, I would go with a European C5 S6 / S8 ECU. It makes life so much easier, and the drive difference compared to running an automatic ECU is like night and day. I wouldn't ever run an automatic ECU in any of my V8 swaps.

Only thing there is that for us fellows with an intake with two swirl flaps, we would have to link them as one right? Or have the second stage flap (high rpm) operated by the S6 ECM's airbox flap control? -Since the S6 and S8 intakes only have one flap?
Please correct me if I have botched any information.

Here is the dyno graph he sent










the line with the big dip in middle was stock tune, this was on a Mustang dyno, which usually read a lot lower than a dynojet

His tune, from my understanding starts from scratch, so it wont matter which ECU is used as long as its ME7.1.1 its designed to be for manual. he isnt patching and band- aid a auto file

also, ive gone down this route, running Daz custom Euro S6 manual tune, drivability was poor, low end power was lacking and had vss issues.

He informed me, he can set it up for either A6 or S6 manifold, so it shouldnt matter

[pee quu]

The s6/s8 intakes have 2 flaps but they both operate at the same time, its not like one opens at one rpm and than the second opens at another.

Why not just pick up an s6/s8 intake manifold or even an intake mani off a a c6 a6 4.2. I think its a c6, that's what I did since it came in a darker gray and is the same mani as the s6/8.

my ecu was an auto and coded for a 6 speed and I cant say I have run into any of these issues. I am still up in their as to why you guys are having so many headaches with your tunes

i understand, but with the Daz tune, S6 style manifold operation was the only option. i am still searching for S6/ C6 intake manifold for a decent price to put on mine, and until then we plan to run it as is, data log and see what works best.

Little video of a launch and pull through 4th gear, 2-3 shift is a little slow as it wanted to go back into first haha
