Was the main reason for the ecu swap to be able to get it tuned realtime/quicker? You have to run an independent wideband with that ecu too don't you? Which one are you going with. I'll be watching ..., I'd looked at these ecu's and am pretty curious if they'll run everything like fans, turbo auxiliary water pump, all dash functions etc
What have you been told regarding the fuel tank, pump, pump assembly, lines etc and their longevity with the ethanol?

Yes that was the biggest reason changing. I'm running a Innovate MTX-L AFR so that will be used and the two factory 02 sensors are removed and blanked off. There is 2 other guys locally running the same ECU in a me7 VAG's and have retained all factory features so that shouldn't be a drama.

Fuel pump and injectors I'm running are e85 safe/capable. I will end up replacing all the under car fuel lines for solid e85 safe lines, but there are guys overseas who have run e85 through the stock lines for years without dramas.

The tuner has recently just tuned and setup a 1.8t A4 running the same plug in ECU so hes familiar with the platform and engine. Fingers crossed all goes smoothly.

Cool super keen to see how it all goes. I only asked re the dash, pump, ancillaries etc because I'd looked into the Haltech 'plu n play' and it turned out that some of the dash features wouldn't run, factory cruise control was unsupported etc
Looks super tidy now that the intake is mafless too. Good luck with it.

Still going to run the TDi badge now that it'll smell like old fruit juice?

[louis19]

Thanks Sam. I’ll keep it updated on how it all goes in the coming week. Hopefully it’s smooth sailing with everything and we can produce some nice numbers.

Yes the TDI badge shall live on

Having run it for over 10 years I have found that issues with E85 are bit over stated/rated, but it is worth keeping mind that it is alcohol so it will "clean" the fuel system for the first few tanks. So any gunk anywhere will get dissolved and pumped. What I do is check the mesh filter on the pump and change the inline fuel filter regularly until it all looks clean. I cut the fuel filter open and check what's inside, when I see no gunk I then revert to normal service intervals.

Thanks for the heads up Garry that’s a great tip. I’ll buy a few fuel filters to have handy for the change over.

I’m running a Walbro 460 in tank pump now so I can replace or clean the fuel pump “sock” easily if and when need be.

After what’s been a long 9-10 months, yesterday my polo went on the rollers for its tune. We ended up with 273fwkw (366whp) - so well north of 300kw/400bhp at the crank for those who work on those figures.

At this power level the limiting factor was the 1000cc injectors on a 3Bar FPR. Originally when starting this project I hadn’t planned on running a full e85 so one day if this power level ever gets boring I can always swap out a couple bits for another big increase.

Big thanks to John for a cracking tune and turning it around so quickly. Hitting the track this weekend for some rolling racing action to give it a shakedown. I’ll be sure to take some footage as well.

Absolutely stoked to see all the hours that have gone into it pay off and have something to show for it.

A quick vid that Dan (Pazuzzu) put together when he came and got a few snippets on the dyno day. Thanks for coming down mate!!

Awesome result man. jeez you're going to have to nurse the throttle to get any traction. Really interested to hear how the around town driveability/idle/progression/off boost etc with the LINK.

[sambb]

Louis how did you strap it down on the dyno. Did you go around the subframes and then diagonally backwards from there?

[simon k]

jeez that's a lot of grunt - it must be very entertaining to drive

do you mind telling tell me your wheel size/offset and tyre size? I've hunted through your thread but can't find anything since the Enkei RPF1 and federal 595s. Doesn't look like you're still on the Enkeis, not sure about the tyres...

Thanks Sam. Its certainly a wild handful now. Lights up 2nd like its on ice. Went to the track this morning for a shakedown and first time properly giving it a good squirt, it was lighting up the tyres in roll racing 3rd gear 140-160kph

Driving around town its spot on, its actually driving the best it ever has. Throttle MAP is set to 1:1 so the pedal is very responsive instead of the lazy factory pedal feel. Idle needed some work but is now very smooth.

I couldn't answer that one for you sorry mate I wasn't watching when he strapped it down.

Cheers Simon. Ive moved away from the Enkei's to some AdvanRacing RG. 16x7.5" Wide, +30 offset with spacers. 225/50 Hankook RS3's.

that's awesome - can't hope for a better result than that -

that's excellent, thank you - 225/50/16 has a diameter of 63.19cm, so I can run 205/55/16 with a diameter of 63.14 - problem solved!

Good stuff. So glad it has turned out well for you and thanks for posting your current build it has been a good read and lets others know what works. You must be very stoked.. Keen to know a few good tuners/engineers etc around the Gold coast/Brisbane so please keep posting your recommendations. Enjoy!

apologies Louis - how thick are your spacers? IE +30 + ??mm

Just looking at the total offset... 16x7.5 +30 has the same inner clearance as the stock 16x6.5 which is handy.
