VEMS Engine management systems, plug & play ECU upgrade

Hi All,

Started a new thread (old thread was "Turbo tuning and rust" or something similar) to see if anyone on here has experience of the VEMS system. I'm going to get one from a guy called Peep in Estonia who has developed a plug in harness for the 944 ECU. It sounds amazing! Another forum member suggested he was offering a discount for multiple orders, though this would be difficult to organise I suspect.
So, has anyone on here made use of (either in a 944 or other vehicle) or have experience of VEMS and can you share any insights?

If there is anyone interested in ordering one, let me know as I plan to order mine next week.
Cheers,
Phil.
 
Hi Phil


I have no experience of VEMS, as you know, but this is not what I would call a simple 'plug and play' system, a quick search on google throws up many issues which seem to require an awful lot of knowledge of the electronics involved to sort out...With any 'stand alone' system...getting a smooth idle and good 'cold start' can be a problem. If I was you I'd do a little R&D first to see if your happy with being able to sort out any issues that may arise. It looks an interesting product but may require a fair bit of setup to get it to run properly, perhaps try and find another 944 turbo owner who has already installed VEMS for their views.

regards

Pete

I'm sure you would also agree I'd contact Wayne Schofield (Which can be tricky sometimes as his always flat out) and ask him
what he'd suggest and what type of tune (How far) Phil is looking for ?

Getting equipment is one decision, who will set it up and get the most out of it another question.

My Engine builder is due to visit Wayne soon with a bespoke 3.0 8v Turbo engine for a Race 944, he's hoping it'll be close to 200bhp per litre.
I'm not sure what ECU and set up he's using but it will be expensive and of course only geared up for Race use and not idling well in traffic, this is why I was advised to leave all the stock ECU and Ignition / Fueling as stock if I wanted the car to start well and idle well and also drive nice in a higher gear at low RPM, but then I've not got a forced induction engine (Yet)

As you know the higher up the scale the power gains are sought after, often the more compromises there can be.

Thanks for this advice gents, it's what I need as I'm not very experienced with ECU mods. I had anticipated getting the system set-up at a rolling road whatever the case.
I'm not after bags of horsepower, I'm after improving the fueling on my current set-up as a priority, then removing the barn door as the next priority, which will naturally lead to improved power, but I am also interested in improving the power and drive-ability with some 'sensible' mods.
I'll try and google around for VEMS feedback a bit more. I'm also hoping Eldavo will chip in as he's apparently spoken at length with Peeps.
What I find particularly attractive is the 'plug and play' backwards compatibility of it. I appreciate it's not really going to be 'plug and play' as in plug it in and it all works a treat but equally I can't be doing with a system that requires constant tweeks and fixes.
 
The vendor is a wally. With regards to 'contacting Wayne Schofield' and asking about MegaSquirt (because this is what it is, really): I am laughing. Wayne s a family friend and, the last thing that I heard, he was doing development work for Mugen, so sorting out Peep's spaghetti will be pretty low on his agenda.
 
Hi all, not been on here for a while, been running megasquirt on my turbo for years now, I know it's not the same as VEMs but is along the same lines.
Do not underestimate how difficult getting a nice idle and cold start is. in my experience a rolling road will tend to focus on performance and safety which may mean poor economy on cruise and they won't be able to help too much with a cold start on a winters day.
 
Yep, still running that way, it still surprises other cars. I must admit I've neglected her a bit lately. Gone back to racing push bikes down mountain.
 
Good to hear the 968 pistons are still intact. Sounds like Barry Hart was right to use machined 968 pistons in his 3.0 turbo. I wonder what happened to that car.

Definitely not a wally. And there is actually no spaghetti involved.
Surprised you say this... Aren't you thinking of someone else?
 
This may be of interest to others considering VEMS for either Turbo or N/A cars, in fact any porsche model (don't know how to cross post forums...?)
Having done my own due diligence and spoken with Peep personally, I am now happy to go ahead and order a VEMS system, for my car. I intend to do so in the next week. I am also buying some ancillary items and getting Peep to provide a config for that set-up.
Now what may interest others: Peep is offering a decent discount for multiple orders. If you have done your own due diligence and are interested in this then let me know ASAP.
What I find equally of interest is Peep's commitment to his product. He is willing to visit me personally to tune my system for a VERY reasonable fee. (though he has stressed that it won't be necessary, but the skeptic in me wants to hold this in reserve). If there were multiple order interests this could be expanded to those as well though the logistics of setting this up may be challenging, I am prepared to see what feedback and interest there is.

To those who have shared their insights and advise regards stand alone engine management systems. Thank You! I appreciate the feedback (particularly wrt cold start and idle issues), and will let you know how I get on with my own system as the installation and set-up progresses.

Best regards,
Phil.
 
I should point out that the standalone is the least troublesome part of the car, currently chasing a possibly torque tube related vibration/noise.
 
VEMS On my N/A 944 with no issues at all, i had it mapped locally to save time, cold start is perfect and the car runs smooth as can be with no MAF, the MAF is now stealth so there but nothing inside, the only thing to give the ECU mod away is the extra Vacuum pipe..

Possibly Tom. I have no doubt that Peep is an intelligent fellow, but I have seen too many reports of his being difficult to deal with and reluctant to answer questions from prospective purchasers to ignore. Spaghetti was a metaphor.

Very happy to hear that this car is still running James. Do you still have the Panasonic F35 cage? I forgot to send you the postage money for it in 2009... [:D]

I would say that tuning an engine requires some essential technical knowledge and a certain scientific approach.
The prospective buyer cannot pretend to just behave like the most basic consumer and get the thing to work without using his brain like he just picked some pre cooked meal off a supermarket shelf to just throw it into the microwave oven to get it cooked.
You have to learn and read on the recipe before attempting to cook the best out of whichever high quality lump of fresh beef you just purchased, and don't get me started on spaghettis [;)]
 
Easy to fit and Peep would always respond with my questions, my Dyno guy had it for 3 hours all sorted and starts on the button.
