Thomasjones Posted May 17, 2020 Share Posted May 17, 2020 Hi all, know it’s probably been asked a few times but can’t find much about it.... does anyone have a recommendation for ECU upgrades on a TT Auto which supports the sequential turbo operation? Thanks Tom Quote Link to comment Share on other sites More sharing options...
Mo Reviews Posted May 17, 2020 Share Posted May 17, 2020 Syvecs and MoTec would be my picks... Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted May 17, 2020 Share Posted May 17, 2020 (edited) I have the Syvecs S6Plus fitted but I couldn’t recommend it. Reason 1 It was sold as plug and play but was far from it, granted I did ask a lot of it but was told (before I bought it) that it was more than capable of doing what I wanted. With a lot of work and a lot of money it was possible but far from easy. I went an alternative route that cost me a lot in mapping to get the car how it is today because none of the Syvecs mappers filled me with any confidence. I went for a bespoke map built from the ground up, all from scratch. Lots of dyno time, lots of road testing, tweaking on both until it was done. Reason 2 Support was and is (in my opinion) terrible for an ECU that costs what this does, their forum is dead so if you are in urgent need of help you are f@#ked unless someone who knows these is a phone call away. My ECU is maxed, no more inputs, no expander kit for this either. That said, it’s got great engine protection and decent traction control two things I wanted. Reason 3 Another guy on here has the same spec car as me (tiptronic VVT-i) but in single turbo form. We bought the ECU at the same time but his needed mapping before mine. He went with a Syvecs recommended mapper and I believe his car still has issues that need sorting. Summing Up Would I recommend going standalone, yes. But I would choose a different ECU. Either a MoTeC M130 or MoTeC M150 and I would do my best to secure Fraser MacKellar as my mapper of choice. Yes the MoTeC will cost you more than a Syvecs as you have to pay extra to unlock parts of the ECU that you get with the Syvecs but the piece of mind you would get and aftermarket support, to me, would be worth paying the extra.

Scooter Posted May 17, 2020 Share Posted May 17, 2020 Why do you want/need a ecu upgrade to the stock system? If you have the stock turbo's even standard hybrids I think you'll gain very little for effort/expense? Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted May 17, 2020 Share Posted May 17, 2020 Why do you want/need a ecu upgrade to the stock system? If you have the stock turbo's even standard hybrids I think you'll gain very little for effort/expense? OEM ECU’s are going faulty due to age, the OEM traction control system is shyte and tries to kill you at every given opportunity, much better knock protection and 21st century tech. Also, if you happen to have the tiptronic box it means the car won’t try to change down over 120 leptons. Protecting your investment and piece of mind as we keep hearing these cars aren't cheap anymore. Bang for buck it isn’t but if you can afford it then why not.

Scooter Posted May 17, 2020 Share Posted May 17, 2020 Fair enough, especially the tiptronic aspect, just not really going to extract much power was my point in case the OP was expecting it. Standalone ecu's never used to be a thing outside of going single, I remember Ian C doing some work with a add on (word escapes me) ECU to trim the stock ECU "just throws in loads of fuel" above 1 bar.

Samurai 20V Posted May 18, 2020 Share Posted May 18, 2020 Fitting a standalone is a choice that needs careful consideration as each persons aim can differ, leading to different choices. In the OP's case, not sure the background, but I think controlling the autobox will be one of the deciding factors. From there, find an ECU and a mapper next. Controlling the sequential twins is a case of having enough outputs, and knowing the logic for the switching, Mike2JZ posted a good guide on it, works on the Link & Syvecs. As for mapping the stock twins, generally not very common, but there are gains to be had, as an example SRD have posted a few cars running strong numbers with stock twins. In my case, I'm in the midst of tuning the twins on my TT6 with the Link plugin, for the reason of us having only 95 on the pumps, car used to run super rich on this fuel. With a standalone, can tune to use water meth. As mentioned by Frank, one of the key points I chose the Link for was the support, Link's forum is very active, they have a Facebook page, very active as well, and their relationship with HPacademy means alot of worked examples, all of which helped me map the car myself. SRD's Mike gave me alot of valuable help, really made being a first time mapper alot less daunting. Quote Link to comment Share on other sites More sharing options...

A piggyback? Yes, it’s pretty much verbatim for what was said. Problem with piggybacks is finding a mapper who is prepared to map one and the lack of protection. The GReddy stuff is so old now and was a cheap solution back then but then TT’s were 5K and parts were abundant so it didn’t matter if things didn’t work out Quote Link to comment Share on other sites More sharing options...
mattdavies Posted May 19, 2020 Share Posted May 19, 2020 The other options with the auto is to piggyback with a HKS loom and run a Link Kurofune. this means you can leave the stock ECU to do the difficult bits and allow the aftermarket Link to run the bits you want.

Burna Posted May 19, 2020 Share Posted May 19, 2020 You can fit a LINK Storm ECU, and let the stock ECU control the autobox. Speak to Lee at SRD, that's what he advised and quoted me on. Quote Link to comment Share on other sites More sharing options...
CBR Posted May 19, 2020 Share Posted May 19, 2020 Proefi is also a very good option Quote Link to comment Share on other sites More sharing options...
