Thankfully I have no Tip in my car ;-) However if you have enough IO to run the tip and the ProEFI can't then that makes me wonder if the Syveccs has more spare IO.

Syveccs seems to have some decent videos out showing how to setup various features but finding information on the ProEFI in general seems easier and possibly more widely supported in the states? Switzer appears to use Syveccs but quite a few other shops are using ProEFI. The Syveccs appears more expensive with software a bit harder to use. They have an ECU that would work in my Subaru though if I got crazy while ProEFI is still working on that platform lol. I'd love a solution for that but won't spend nearly as much on that car ;-)

Can anyone speak to the differences between the ProEFI 112 and 128? I've been able to discern the 112 is faster with more CAN channels, drives fewer injectors though so cannot run dual fuel (I wouldn't on this car but would've on my Supra). The 112 is physically smaller and is supposed to be the ECU of choice for the 996 platform. Does it have equal IO other than the injectors? ProEFI lists zero information for it. Do they have additional hardware planned near term? I saw somewhere that Syveccs may be looking to release a less expensive box but no other information and the S8 for the 996 seems to be one of their top boxes.

IO is a concern of mine because of the things I did with my Supra. Warning lights, alky injection, staged fuel pumps, and other toys were planned. I don't expect to need quite so much with this platform and the CAN displays seem to help but this is why I'm asking. Nothing worse than needing an IO and having run out! Not having enough injector drivers on my last car really sucked when I decided I might want to go dual fuel.

P.S. I had to laugh watching one of Jason's ProEFI videos. Usually exhaust drone can't be captured on a recording easily but holy crap on some of his it actually sounds worse than mine! Someone sell that man an exhaust! I also had to chuckle at the piles of warning lights lit on his dash in some videos.

 

I would like to know the same thing. I thought most ProEFI users are running the 112.
Isn't the 112 / 128 still used as a plug-n-play piggyback for the 996T?

AEM states the infinity is a full stand alone and replaces the stock ECU.

Out of all the Syvecs Dealers that they list for the US, not one had any listing or information for it. lol.

 

its worth a trip up to garth shop to see exactly how the proefi works. the 112 is smaller than the 128 and it might not be what you want. the 128 has 5 i/o and will handle as many sensors as you want

i don't think the 112 is any faster than the 128 because when it came out i asked garth if i needed to go this route. his reply was mine (128) was bigger and no need to go backwards.

 

From what I understand the 112 has a smaller footprint and is a slightly more straight forward install. It also has more processing power, but not enough to warrant a change from 128 if you already have it. Other than that I'm not sure what it gives up over the 128

 

I think of the 996TTs that are up & running most, if not all, are on the 128. 112 was released in fall 2014 and there are at least 3 members running (inducing myself) with builds nearing completion.

From what I understand ProEFI can be used as either a piggyback or full standalone. Last I spoke to Garth he's setting up my 112 as a full stand alone

 

prior to the release of the 112 all the 128 setups were running as a piggyback. it was things like fan control for the heat/a/c c/c that held it up as being a full standalone. since the release of the 112 either unit can now be run as full standalone without any use of the factory me .( ic ant speak for emissions as i am still piggyback for now and dme tuned to pass) garth was instrumental in bringing this to the front and the 112 was a great new tool for those to use. it incorporates the cruise control stalk for all the boost, rpm, launch control etc settings so no switches need to be wired up. mine was done prior to this so i have the switches. now its able to be done either way, owners choice

from what i understand the 112 is physically smaller and has 3? i/o were the 128 is larger with 5 i/o. i don't think there any other difference processor wise as the 128 is still the most advanced computer proof sells but i could be mistaken. as i said prior i was ready to make the switch when the 112 came out and garth advised me it was unecessary and a step backwards regarding i/o capability and inj. capability

i know this has devolved into a proefi thread and i apologize to the o/p. heres a couple pics of the 2 units and ill bow out as I'm hugely biased!!

 

Heh, I don't think it's devolved as the information is all good and helps others too! I'm in the process of exchanging some email with Lawerence at Undercover concerning the system. Garth's shop is a few hours away else I'd pop over and ask questions for sure!

I'm interested in Syveccs information too. As I said it's way easier to find information on the ProEFI and so far almost no information on the Infinity which is a shame.

Honestly, when it comes to tuning something many systems can run the car but it's the extras like datalogging, traction control, and adaptive strategies/engine protection that make a system easier to use. Ease of use of the software and tools to analyze logs are also important features, I can't tell you how nice it was not to have to use a damned spreadsheet to figure out what was going on when I first used the AEM! Support and a community helping one another is also very important to ME. End of day I expect to be tuning and asking questions myself and working with others is a powerful multiplier...

 

Another thing you should be looking at is ...want tuner would you fell comfortable with ..
No matter what ecu you have if the tuner is crap your car will run like crap... I personally think you should find a shop that is convenient and is willing to do what you want.

I personally think the Proefi ecu is far more superior to the Syveccs..
Another + Proefi is located in the U.S and you can contact them anytime during their operation hours for technical support..

The reason why I went with the 128 box instead of the 112, is because you are able to remote tune on the 128 box... So if any changes/upgrades occur with your car... You will have the opportunity to tune remotely...Instead of flying down your ..
Also the 128 is still the "KING PIN" of the ecus proefi offers.

Honestly? If I've got a good base tune and software that's reasonably straightforward and not buggy I don't need much support. Driveability tuning is hard to do, way harder than tuning for max power generally. It takes time and it takes someone picky to weed out the little areas that have issues - I like doing it I tuned my Supra to drive damn near stock and I did the same thing for several others who brought cars to me after local tuners put truly ****ty tunes on them. It's funny, I've owned several completely stock OEM cars and found bugs in their tuning, little glitches with the throttle or dead spots where accel tuning was screwed up. One of the biggest reasons why I want a standalone over just a flash is because I like to tweak, twiddle, and fiddle until the car runs perfectly. I like CONTROL and that's something no OEM ECU gives you very easily. Datalogging will show you where things aren't right and with some work you can get the car running smooth. I probably had a thousand hours worth of tweaking in my Supra and my map would start the car in everything from mid Summer heat to stone cold below freezing and warm it just like stock. AEM didn't tune those maps well because they sat at sea level in Cali and never got the weather I did in Virginia. Tons of fun ;-) Sadly AEM appears to have flushed the old forums and all of the tech discussions with them <sigh> Garth is pretty close, if I need support after the fact and buy from him I'll head his way.

To be fair there's US Syveccs support yes? I know it's primarily a Euro based system but I believe they have a US distributor. This is one of the reasons why forums and support discussions are important to me. On the AEM forums members figured out ALL sorts of things with the boxes and I think I called AEM support maybe 2x. I also beta tested firmware for AEM, caused them to delay a huge release too which was good considering an issue I uncovered. AEM actually flew someone out to look at it, thankfully I don't foresee needing that level of support on this platform - I hope! I wont' be going nearly as crazy as I did with the Supra (I think) and there are others waaay ahead of me already

Why wouldn't you be able to tune remotely with the 112? A remote desktop session ought to work for that on a dyno. That's one interesting thing about Syveccs, it uses an ethernet cable for it's connection and not a CAN cable. I'm not yet sure if it's using IP for it's data transfer but if it is then remote tuning that box ought to be as easy as a properly setup VPN! I personally think that's a smart move on their part having seen all sorts of issues with serial ports (which you cannot find anymore) and knowing that USB isn't always as good as it could be on many laptops. Everything has a NIC and it's a FAST port. I've seen a few posts about the ProEFI "bricking" but this seems to be having a battery die during programming so honestly that's not too big a surprise. I know a few V1 AEM had issues and I had a spare EEPROM for mine on hand just in case. Overall it seems this isn't a big issue anymore which is good.

Still trying to understand the differences between the 128 and 112. Other than what I detailed above I'm not sure. Faster processor just means better datalogging of more channels and maybe some more complex code but the 128 seems to have no issues. Fewer injectors but unsure about leftover IO.

 

My Syvecs is WiFi, dont even need to be in the car to tune it

 

In what way do you think the Pro EFI is 'far' superior?
Not looking for an argument just curious, you have Pro EFI I have Syvecs we will both believe we have the superior product thats human nature so interesting to see, for a start I dont believe your Pro EFI can properly control a Tip, the syvecs has full control.

Your correct about support but that just means picking the correct time of day to call the support team, we are in the UK and deal with Link in New Zealand all the time.

Most correct is dont pick an ECU pick a tuner, but the OP wants to do most of the tuning himself.

 

My apologies.. I meant to say: Far more superior than the AEM lol..
I have no knowledge with Syveccs..

When I Contact the guys at Undercover I was inquiring about the 112 and didn't need the 128 boxs extra featurs... The 112 is plenty..

Then Garth told me the 112 is a new ecu and it is still under development and testing.. (I think thats why you we're not able to find anything on the website) Apparently it uses a different software than the 128 and only special dealers have access to tune.. Abe Berro

 

As the OP is into Supras I found this, may be interesting to read

http://www.mkivsupra.net/vbb/showthr...t=AEM+Infinity

 

Think I'm going with the Infinity route now. I'll be tuning my own car and have experience with the previous AEM EMS versions so it's best choice for me. Everything I've read about it is great as well

I'm sure I won't be the first. There has to be someone out there installing it as we speak! lol.
