Here is a list of features Syvecs has on their website.

It has the ability to do the job of the factory ECU and a hell of alot more!!!

For example it will control the VTG's, Variocams, etc...etc...

They would like to use my car as a donor.

What do you guys think?

 

Is that a piggyback or true stand alone OEM ECU taken out?
Depends on the cost, ProEFI and MoTec come to mind as know piggyback solutions.

 

It is a true stand alone ecu.

 

Is it Syvecs ECU?

http://www.syvecs.com/s8c.php

How do you plan to run ABS, PSM, PASM etc.. ?

I think it's better to use ProEFI, i have one in stock if you are interested.

 

Yes it is the syvecs.

This is questions that they will have to answer, but they did say what ever the stock ECU will do the syvecs will do better or just as good.

Why do you reccommend ProEFI over Syvecs?

What I would like to know is what is the advantage of running one of these Ecu's when the 997tt ecu is open?

Is it because not everyone has the knowledge or the correct files to write to the 997 Ecu?

I heard there is an advantage for a race car but thats about it?

 

20k rpm limit? I'm assuming an engine would melt far before it got that high, so basically this setting means no over-rev protection right?

 

capable of having 20k RPM limiter not ONLY 20k Limiter is what it means.. You can set the limiter anywhere you like..

There are plenty of good options for stand alone ecu tuning.. They all cost a decent amount $$$ thats all..

Are there fully programmable PWM'd outputs ( and inputs too ), preferably with closed loop capability in relation to MAP & RPM? If not, you're not going to be able to control VGT turbos.

 

Hey Nick...if you're planning to continue running VTG's, what would be the benefit of the standalone unit? The factory ECU is well capable of being tuned for any VTG setup. Why take a chance?

Personally, I wouldn't do it, unless you switch to a non-VTG setup..then it could sound interesting. But even then, there are plenty of other tried and true options for non-VTG cars, like the ProEFI that Emre offered.

 

There are a great many advantages to running a Syvecs (or any other standalone) over a Rom-flash. Admittedly a little overkill for those owners that just want some quick bolt on additions, but when pushing the boundaries having something like low oil pressure or fuel pressure safety trips to protect your investment makes savvy sense to me. Why spend thousands on your P&J engine to then make compromises on management? What Nick has listed is just a fraction of what the unit is capable of. Ryan @ Syvecs would be the man to cover this topic in more detail and he would be more than willing to answer any questions you may have, nice guy too.

 

Hi,
im sorry to barge in and start posting. Most all of you dont know me. I would like to shed some light on this as there is much misconception floating around .

I have been working on this project prior to Syvecs being involved. We were looking for full integration ECU as there are some limitations with running piggyback. Syvecs and Switzer made this possible as Syvecs provided the hardware and some of the framework and Switzer provided the data needed to run the auxiliary functions.

Ryan can elaborate on this as also few users that have been selected to run the debugging. Currently the 996 kit is in reproduction stage and will be installed onsite at Syvecs UK or Syvecs US. There is nothing publicly available for the 997. (but its being worked on).

 

Hi Nick,

I wouldn't go.
I have really little time for leisure, so
I only run well known solutions, in the past I tried some "standalone" mods on other cars or bikes, the best way to go from passion to nightmare...

Now if you have plenty of time and like beeing a " pionneer"...
