Thanks everyone, just sat and read you replies.[]

Well it looks like Vitesse then for me.

Time to leave some print outs of the Vitesse website on the kitchen table in the hope that Father Xmas is good to me this year[]

So am I correct in thinking you need the Vitesse MAF at $1250 and the V Flex software at $695 or does the MAF kit come ready to plug and play.

Does Jon Mitchel still sell them? I thought at one time he had an agreement to disribute them in the UK? Might be an easier option, especially if they're in stock?

Just went on John site and it looks like he does the Vitesse one.

You only need the MAF kit, the Vflex thingie is a nice optional extra. Certainly worth emailing Vitesse direct - Got a very quick (within 2 minutes !) and helpful reply when I did so the other week.

Just to add - Vitesse also reckoned you need a 3 bar FPR (which comes with the Promax L2 kit as far as I recall) but also bigger injectors fitted to use their kit. Don't know if folk concur with this ?

 

[edh]

yes - he won't warrant his kit with std injectors (but will sell you the FPR and Injectors) the pigtail cable MAF to harness is worth having as well.

It's a lot of money to spend if you're going to leave it there - but if you plan to do more tuning in the future (SPS turbo for example) it's a great starting point

I'd agree with JMG that bang for buck the best performance improvement is MBC, chips and DPW

All the standalones require a heck of a lot of installation and even more time setting up.

This is one of my personal theories when the first thing I hear from other people with tuned cars is.. are you running stand alone engine management?

Everyone seems to know someone who can 'easily' set up various engine management systems and get them 'spot on'.

...who actually owns, has ever owned or has ever known anyone who's owned a car running stand alone mangement that ran as well as a standard car? I have NEVER seen a road car running one that doesn't have problems or need further work. Honestly I think they cause WAY more harm than good.

On the flip side people have seen big improvements from the Vitesse maf's and I've never been in one with a tuning problem.

I think JamesO was please with his Megasquirt install. Certainly its not an easily thing to setup, there are a lot of variables that can cause an issue. Personnaly I still think it is the way to go if you know what you are doing. I have been looking at the Link G4 storm and the EmeraldM3d. One of the features I like on them both is flat shift, they also have outputs to shift lights and various configurable I/O. They really are very flexible devices and the kind of setup you would need to get a really good standalone setup. The guy who makes the Emerald ECU is in the UK so he might be a good choice. I am certainly keen to give it a go.

Well for cars where there is alot of demand for this sort of thing, like Scoobies, you can buy standalone kits with maps already pre-installed that get you 90% of the way there and you need to simply fine tune it. Also with modern cars the sensors you need are already installed from stock so these are basically much more plug and play. I think why they are apprently less reliable is probably more to do with poor tuners out there and some of the knumb-skulls that own Scoobies who think they know more than they do about tuning. But unfortuantely with little demand for 944 turbo standalone kits no-one has developed a cost effective plug and play version. The only apparent plug and play one i've seen is the Wolf 3d which came with start up maps and the connectors modified to plug into the stock loom. Of course you end up in the same boat once you start wanting to ditch the AFM and go MAF, MAP or MAF/MAP, go fully sequential injection and utilise all the other benefits.

The one feature which is a must with a turbo is knock sensor capability and is sadly a feature the vast majority (almost all) standalone units don't have. The Link ECU's are one of the few that do. However there is a company called JLS that produce a unit called the Safeguard which can work with our knock sensors and can retard ignition as soon as knock is detected, but I don't think it can do much else. A fully integrated knock protection system will retard ignition, adjust fueling and boost depending upon the severity of knock detected. It is the single most important feature on our cars as the knock system is not just a safety device but it is almost a closed loop system detecting the onset of knock and managing it actively.

I agree, knock sensing is a very important feature. I like the look of the Link ECU, there is a company Thor motorsport near to me who supply the system. I might give them a call. I like the emeraldM3d ecu as well but it doesnt have knock sensing *yet*. They seem like they might be the kind of small company that might be willing to work a bit harder to get their ECU to work on the 944 than some of the larger companies. Perhaps working with a small company like this as a community could yield some good results for us?

The Vitesse MAF is worth ordering with the V-flex option (MAP sensor + optional boost solenoid) which allows to set a peak boost pressure over which the ignition will be cut - when I was fiddling for the first time with the boost control I reached something like 23psi at 3500 rpm and was sure pleased to have the ignition cut.

An easy and cheap way to monitor knock on your own is to install a KnockView (from the same person who makes the SciVision MAF kit).
It's one of the first devices I purchased when I bought my turbo 3 years ago and all the tuning I do with the Vitesse kit is primarily based on what the KnockView tells me.
