Tiptronic ecu options....?

[Glanza_Mike]

Hi guys,

 

Just wondering if any of you know which ecus are suitable for the tiptronic except from the syvecs s6+? And i know that still isn't 100% sorted.

 

Ideally i was thinking of standalone units as i'd like to remove the 115mph kick down thing but also throw some good piggybacks in the mixer if you think they are good thanks.

 

And the reason i say except syvecs is that i just can't see myself spending nearly 4k on an ecu (ecu,sensors,fitting,mapping) simple as that.

The MoTeC M150 will do the trick as it has enough inputs but it will cost more then the Syvecs S6+ and you will have to pay for the R&D to be done. Other than the MoTeC I believe your only other option for a standalone ECU is the S6+.

 

The problem with running a piggyback is that the gearbox ECU is expecting certain things to happen so if you single the car you are changing the way the engine & box work in harmony.

 

At least that is my very basic understanding of why a standalone on an auto is better than piggyback.

Okay mate thanks for your reply, does that mean the only option other than those two very expensive options is a piggyback?

 

Like an emanage ultimate?

To the best of my limited knowledge yes, I wouldn't use an E manage Ultimate though. You could look at fitting a standalone and just using it to run the engine essentially making it a piggyback but that is probably far from cost effective. What sort of budget have you in mind for just the ECU & sensors?

[Glanza_Mike]

Is the Emanage ultimate not a good piggyback mate? I haven't done much feading on them yet i just see them auoted a lot on here.

 

And as for budget i haven't really thought about it yet, i'll spend what i need to really, i just cannot justify the outlay for a Syvecs. It would come to nearly half what i paid for my car in stock form lol

There were problems getting the Emanage ultimate to work successfully on VVTI Supras but i'm going back to 2008-2009, there were also issues getting them running as some had a faulty ignition chip. Some reading for you - emanage ultimate problems mkivsupra

 

I don't know of anyone who is prepared to map them anymore but Ian C maybe able to help you - http://www.mkivsupra.net/vbb/member.php?116-Ian-C if that is the route you want to choose.

Thanks for your help mate, i'll have a read through some of those threads when i get some spare time.

 

I just noticed the Map3ecu has FCD and speed limit remover built into the ecu and the yanks seem to rate it highly, do you think there's any chance that speed limit remover would be different to the current one we all use and have a chance at resolving the kick down problem? probably unlikely but hey.

The thing is Mike, although you will be able to get it working with an ECU in piggyback, it won't solve the high speed kickdown issue.

 

So better to go with a Syvecs, which while expensive, does provide you with decent traction control, adjustable maps (Inc a pin protected immobiliser if you want) and will cut your engine off in the case of low oil pressure, running lean etc. You can also ditch the stock DBW throttle, which can be problematic and are very expensive to replace.

I'd be going with Syvecs if I was in your position, Mike. The ECU is superb, just that Jay is having a couple of calibration issues.

 

Lee @ SRD can map the Tiptronic element, so maybe look to him to map it?

[Chris Wilson]

I would imagine there are quite a few standalone ECU's that could run the Tiptronic and everything else, the problem seems to be getting the research and development done to find out just how a stock VVTi is controlled, then if required mimicking this with suitable alterations to enhance the power delivery from a modified engine with very different torque / RPM characteristics.

 

I can imagine getting the data and then getting a different ecu to run similarly is hugely time consuming. Time costs money, who will want to pay for the R&D? An ECU maker / seller can swallow all or some of it if sales levels for such ecus are high, but what if they are only going to flog a dozen or so of them....? Should a mapper swallow it, then lock the ecu and protect his work from copying?

 

DTA had a supposedly uncrackable map lock on their ecus, meaning gaining access to a password locked ecu without that password resulted in the map within being wiped. I was told a disgruntled employee revealed there was a master password embedded to unlock any locked DTA unit without losing the embedded map data. He published it on the net...Many tuners / mappers were VERY unhappy.
