The Project Pad

Not certain if i'm not understanding, but i know of at least one 1.8t audi guy running the Infinity series....

Funny.. Just last week red about 280Z Datsun with aan engine, twin turbos, 10000rpm, billet diffuser plenum intake, and AEM Infinity ecu.

Good that this post goes up, I'm still thinking on buying VEMS for a 20v project.

However, standalone EFI aren't common in my area and the only tuners around me seems to be MS(and Sybele)-only.
Besides those "lel i kno not wat iz VMES, buy ms", I had a more neutral answer which was "As long as it looks like a decent standalone, we could manage to tune it", so here comes my question :

How decent must be a "MS-tuner" to get along with VEMS ?

When I made my decision it came down to a few things.

A local tuner who's very reputable dismissed MS3x because it has an unbearable amount of signal noise.

VEMS has great community support. You can easily get a base tune at home and be safe to drive to the dyno.

All the dyno tuner has to do is manage air:fuel:spark. Period. That's it. What's going to complicate things, is, if he's used to Haltech or Motec or MegaSquirt, etc, then he's going to have to adapt to the program/interface of the EMS you choose.

So you're paying for him to learn on the fly. If your base tune is solid, and he's a quick learner, one would hope it won't be too costly.

Another thing to consider is, see if whatever EMS you choose has a dyno in driving distance that you can go to. Get a base tune at home, make sure it seems safe/do necessary tweaks yourself, and drive to the dyno.

Since I bought VEMS, MaxxECU has come on pretty big in Europe. Lots of good features and people seem to like it as a platform. To do it over again, I'd still get VEMS, but that's because there is lots more "regional" support for it compared to others.

Yep that's what I had in mind but wasn't sure to be right.

Thank you
