Went down to visit car. Dave indicated my car going to dyno this week.

We will tune for:
91 only
91 with Aquamist running 100%

I just want to be able to beat on it without burning it up at track.

For kicks we will go e85 and extra fueling.

Congratulations, but don’t you need to break in the engine first before tuning and dyno it?!

Well dyno work has begun.

AU wrote me today...

Your car is on the dyno right now. So far, we’ve been working on the base calibration (idle and startup quality and target air fuel ratios. We are also getting the failsafes dialed in on the meth system so that they function appropriately. I hope to start making some actual power pulls by tomorrow afternoon.

500 here we come.:tweetz:
Well I doubt we will get anywhere near 500 on this first round (more like 400) on 91oct and Meth but it will probably end up being my street/track tune. Once we add the 5th injector and e85 we will probably get close.

I was given poor info recently and they have not put the 5th injector system on yet (Megasquirt). But I am going to have him do that and have a setup for e85.

First tune done today.
91oct only - 347 on the dyno

Next he will see what he can do for usable power range for track and beyond. My hope is that we can get into low 400s with meth and 91. Then we will see where we can go with e85 and meth.

Still good number with 91 octane, but why not 93 octane?

Update on tuning.

Tuner worked a little more with the 91 only tune and feels he has achieved a 364whp level that is perfectly stable and quite safe.

He also turned the meth system on and at 22psi is making well over 400. He feels that he will be able to reach 450 with just 91 and methanol (running 100% meth) which was my hope. If that plays out, we should be able to get close to 500 with e85 and the extra injector plus methanol.

Tuner is Dave at AUTuning in Huntington Beach, CA

That’s very nice and strong numbers. Keep us updated [emoji4]

Can anyone shed some light on a problem I have with my my 5 golf iPod docking station in the center armrest. I can’t seem to get it to work I’ve my iPod plugged in and I press the cd button once or twice all I get is “no cd” and that’s it.

I heard from tuner today.....

Hey Larry. I have been going back and forth with Eurodyne trying to resolve an issue within their software for your particular ECU. We can’t get boost above 22 psi with the Eurodyne software. This is perfect for the 91 octane tune which we are now making 370 whp with. But with the methanol injection activated, we can take advantage of higher boost levels that we currently can’t reach because of the software limitation. At 22 psi with the methanol system activated, we are making 420 whp. I am going to pull the car off the dyno today and schedule time for our team to finish up the suspension bits, ride height, alignment and few other miscellaneous tasks. Once we find a resolution to the software issue, we can revisit that on the dyno. In the meantime, I’d like to wrap up the car and get it back to you so you can shake it down and work out all of the bugs. I’ll update you on the progress.

I can hardly wait to get this thing to the track. 420 is a little shy of what I was going for on my track tune but should still be boat loads of fun and will still surprise a few folks until we can get the boost issue sorted.

You need a bigger MAP sensor, that's why it won't read over that boost level.

Well not according to tuner, asked him that. He said Eurodyne has a special setting for the boost control sensor that is supposed to allow them to hit 30psi. He was on the phone with owner of Eurodyne and indicated that it may be some hardcoded limitation in the ECU ver. and that they would work on a solution.

He also told me he took it out for a drive and said the car is blazing and will roast the tires in 3rd gear. Spools almost as early as K04, very little lag.

Note - of course this won't be the first time the obvious answer is denied only to find out later it was the solution. I traded emails with Ryan (HYDE16) who has an EFR7163 using n75 and Eurodyne and he was running 33psi with a 2.5bar map, this was on his MK6 GTI.

370whp - 91oct only
420whp - 91oct and meth - low boost 22psi

Read this one[emoji116]my friend, I believe you need the 3bar MAP



I had it with the BWA engine with the GTX28 setup.

Tuner put a 3 Bar map on and tuned for it but it didn't make any diff. He says it is a Eurodyne problem and is working with them to get a solution.

Update

So I talked with Dave this morning. He has been working on the boost problem. Can't make boost past 22psi. He has been unable to solve the issue using Eurodyne software so he decided to reach out to Frank Mabo (Mabotech) who writes his own software and has a lot of FSI experience to see if they can overcome the issue. Frank uses Eurodyne to do the file transfer but writes his own software. Fingers crossed. My files have been sent to Frank and he will check in with him this week.

Dave (tuner) has driven the car and I asked him about the brakes and suspension.

When I put in the 18z f/r brakes worry was about pedal travel so we put in the TTRS master cylinder. Dave said the brakes were very responsive and require very little pedal travel. He said that he had installed 17z calipers on his Audi and liked them except for the extra pedal travel which he said is typical when installing these type calipers with stock master cylinder. He has driven a bunch of them.

He said that they have the suspension dialed in and considering all the mods I was worried how rough it might be but he said it rides well. There are now lots of spherical bearings instead of bushings so I was concerned. However, he said the car ride well at least on the smooth roads around his shop.

My tune is complete

I spoke with Dave Marsh this morning, my tune is finished. Because they have done so much work to the car over a long period of time they are going to go back and double check all the work before turning it over to me.

Car made 480whp running 27lbs of boost.
Fuel - 91oct in tank and 100% Methanol through Aquamist.

Dave said he was impressed with the turbo and said it spools quick and early like a K04 almost. Full boost at 3500 rpm gives a very nice wide power band.

Once I get the car back I will do a full review with GoPro track footage etc. Looking forward to taking it out for the first time in over 2 years.
