Hoping for a better MK4 2.0T tune...

**SMG8vT** · 10-15-2010 11:43 PM

Ok guys, I know there's quite a few of us MK4 2.0T guys kicking around. The C2 tune is definitely a little bit limited by the injectors to a power limit of 260-280whp. I've talked to a few people who would be very interested in a better tune for our ECU's that would support more fuel and open up the 300whp range for us.

Jeff at United charges $1500 for a custom tune and if only he was local I would probably cough up the cash and have it done but I wondered if we could maybe get a few people together on the price of the custom tune and physically let Jeff tune a volunteer's car in CT?

Even if you're not shooting for over 300whp, more fuel would be a really nice safety net if something were to go wrong with your boost control system. Just trying to toss some ideas around and maybe get something going. Post up if this is something you would be interested in.

740cc Unitronic 1.8T big turbo ECU tune would be my drug of choice if I ever got a build going.

Wonder how we could get that working with an AEG though, as it's nearly plug and play on the DBWs.

**SMG8vT** · 10-16-2010 11:31 AM

Yeah, or especially being able to run Eurodyne would be great but it's scary to think about what a wiring nightmare that could turn into, and wiring isn't my thing at all so I'd have to pay someone to tackle it for me. Something plug and play would be really ideal.

Standalone is a good option and there are options for a plug and play ECU but then you have to get it tuned anyway. Plus you lose a lot of the features of a stock ECU.

The only real way to win this is a better flash tune, unless someone figures out how to do the 1.8T ECU swap on the older cars.

I guess I'm not the only one wishing for a bit of adjustment capability. I would love to have a tuning package for 2.0's, and I am quite frustrated that nobody offers anything unless its for the 1.8. It seems to me that the 2.0 market is quite under-served when it comes to this sort of thing, and working with the stock ECU....

**mk4jetta2.0sc** · 10-18-2010 02:39 PM

yeah id have to agree ive been slowly piecing together my own turbo kit and have been looking around for a good tune but it seems that the only decent ones are C2 and jeffs but im in college and don't have the best job so $1500 is a little crazy plus i live in wisconsin

**SMG8vT** · 10-18-2010 02:44 PM

Yeah, I mean the C2 tune (done by Jeff) is quite capable but the scary thing is if you overboost by accident you will run out of fuel even if your bottom end is built to take the power. It feels so sketchy knowing that the only thing between you and melted pistons is a leak-free vacuum hose running to the wastegate. A bit of breathing room with a solid tune for some nice big injectors is badly needed IMO.

**SMG8vT** · 10-18-2010 02:47 PM

If someone is local to Jeff and wants to get their car upgraded to a bigger tune, please post up and I will personally put some cash towards that so we can get something better for the community. Honesty it would be sweet if we could identify a volunteer Jeff would do a group buy on tuning for maybe $500 per person so with 3 cars signed up we should have enough to pay Jeff for the tuning.

Maybe the problem is that Jeff's tunes are too cheap? I'd definitely pay $500-600 for an off-the-shelf tune for some bigger injectors because we know if it comes from Jeff it's going to be solid.

**SMG8vT** · 12-02-2010 11:49 PM

Bump...

**rommeldawg** · 12-05-2010 10:34 AM

i am working on a build right now... once the i am done with the assembly and get the car running (i have a ecu with a "c2" flash on it) i will be looking at getting a tune... if i am not able to find someone locally i might trailer the car to ct or louisville and have it done... either way i'll be happy to share whatever info comes from this

**Rolands76xx** · 12-05-2010 02:10 PM

Im in NYC and would volunteer for the tune as long its in the $400 range, the only catch is im still building, should be done with piping and intercooler setup this week, all i need atfer that are injectors, bigger MAF flange, and the flash from Jeff.... Which would cost around the same money... I say we gather some people together also... 260-280 Hp range is ok for me, but it is very limited and thats just pushing the injectors i guess.... 300+ shouldnt be a problem....... we just need 2.0T people with ambition

..... count me in for the group thing ( as soon as im done)

Aren't AEB's cable throttle???

**rommeldawg** · 12-05-2010 04:22 PM

use awp 1.8t ecu and eurodyne 830cc tune... i just got a reply from quintin at rai, this is what he used to make 375whp

**SMG8vT** · 12-05-2010 05:01 PM

Quintin had a DBW 2.0, so that makes things easy for the 1.8T ECU swap. Nobody has done the swap for the DBC cars yet. I wish someone would figure it out so we can copy them.

I actually emailed C2 a few days ago and they seemed really interested in working on a new tune for our stock ECU's! I haven't heard back but it seemed positive. Are any of you guys close to C2? They almost made it sound like they didn't need to have a car there but it wasn't totally clear, that's what I'm waiting to hear back on.

**rommeldawg** · 12-05-2010 05:10 PM

sorry mine is also dbw... missed that you were looking for dbc tune

I don't know AEBs well, but I believe so, these would be the early Passats and A4s with 1.8Ts (I could be wrong) but it could have been such a short production run that there might not be much for tuning options.

**SMG8vT** · 01-13-2011 02:08 AM

Sigh...

**Jefnes3** · 01-13-2011 05:33 PM

I have some AEG stuff, data ported over from my AEB tuning.

415cc, 70mm MAF
630cc, 70mm MAF

630cc, ProMaf jr.

Holy crap! Emailed..

**Rolands76xx** · 01-14-2011 12:13 PM

Wait im excited! What exactly does that mean?!?!?

**Rolands76xx** · 01-18-2011 07:21 PM

Bump for update!

**Rolands76xx** · 02-04-2011 03:12 PM

... Am i the only one interested in the better tune?

**SMG8vT** · 02-04-2011 03:16 PM

Nope I am dying for one as well. vdubbugman53 has expressed interest too.

**Rolands76xx** · 02-04-2011 03:36 PM

did jefff say anythin about a 630cc tune?

**Jefnes3** · 02-05-2011 10:11 PM

someone bring me ~any AEG powered car. (no need for turbo)

Wait for a bit until all the snow melts.

I am willing to donate one of my 2 spare ECUs if that is any help.

**Rolands76xx** · 02-07-2011 02:32 PM

Im willing to take my aeg since im in nyc, but it would have to be like first weekend of march

Thanks, I don't need a spare ecu. (have a few already)

The 630 tune is fairly well sussed out, I just need a car to verify a few things.

**SMG8vT** · 03-10-2011 01:59 PM

Wondering the same thing.

**Rolands76xx** · 03-10-2011 06:49 PM

I would love to go, but im still working on my dtcs for running rich, not sure if he can use a car thats limping
