I like to do standalone but dont want a laptop version that I need to quit work to invest time to understand tune it

I was thinking the EM3e

Why do you want standalone then? Not that there's anything wrong with it but you can get decent performance without it too.

i agree with pat,

Theres nothing wrong with some of the chip sets, Vittesse also have the piggy back and you can tune timing and fuel mixtures.

never heard of SDS but id use A'PEXi power FC since it has a quite nice user hand controller if you dont want a laptop.

SDS will work, but doesnt really give you anything over the stock DME/KLR. IMHO its a bit of a pointless standalone but thats me. And once you total up the prices, it comes to nearly the same prices as vastly superior systems like Link Storms.

I used SDS on my old 951. It's a great beginner system to learn how to tune. It doesn't do true 3D mapping, you tune for fuel on a rpm basis, then you tune the MAP pressure "multiplier" and that's it. It's easy, and a great way to learn how to tune.

As theedge says, there's much better systems out there for same or cheaper than SDS, which is quite expensive for what you get. Only reason I chose them back then was because they were local to me.

+1 and your still going to need a crank trigger. And what kind of support can you expect?
Something that other 951 guys are running or 951 vendors supply would give you more help on here if needed.

When it came time to do reference and Sync sensors you may want to consider doing a magnet set up on your cam instead of the crank shaft.

Just get a MAF system with piggyback if you don't want to dive into the standalone world and learn how to tune.

If you want to go standalone and not have to learn to tune, there are several vendors out there that could provide you with a pretty much plug-and-play setup with a very good basemap if your mods are common, then you wouldn't have to worry about starting from scratch with a not-so-common ECU.

thanks for the info guys

I good piggyback system, M-Tune, Vitesse, and even a "decent" chip set for your particular car will provide you with a great tune. The issues with the trigger install, wiring, and then the biggest hurdle, getting the car to run as well as the Motrinic at all engine speeds and boost levels required a big investment in time and money if you need help getting things as good as factory.

If you are building a beast, then it's worthwile. There are more issues than payback for 90% of us nutty 951 nuts.

IMO like you said, if you've got a hell of an engine then yes standalone it. if its a few mods like what most people do as in new turbo, injectors and exhaust... id get a good chip set from those 2 vendors. if i've got cams headwork and some crazy stuff then standalone.
