Is anyone using the Vems PnP Engine Management? If so, what opinions do you have? Is it as good as advertised?

V2Rocket

Yes, it is great and very easy to use.
I think I've had mine for...6 months at least?
Car runs great, tuning is very simple once you spend a little time getting to know the software (click that, what's that do...etc)

And the support is quick if needed.

Are you running it on a 944 Turbo ?

V2Rocket

On my NA.
As it comes, it is set up for boost (all the tuning tables have cells way beyond atmospheric pressure...I think up to 3 bar? I don't remember right now)

blade7

You know this is the 944 Turbo and Turbo-S forum...

V2Rocket

What's your point?
He asked if anyone had VEMS PnP.
I do.
So I answered.

Installing VEMS to a 951 and running it is the same process as putting it in an NA...maybe a few more wires to plug in. But it's PnP, and easy to P with once P'd in

There are a lot more 951's running VEMS than 944 NA. Just to mention...

Raceboy, what is the price for a complete unit for my 951?

PorscheG96

Based on a few 944 owners touting their Vems ECU's, I'm interested in this option for my new engine build and of course, am skeptical. Does the PnP even warrant consideration for a street car with stock gauges and have CEL provisions for smog test, etc?

blade7

My point is you keep endorsing it seemingly without any practical experience of running it on a 951.

Raceboy is not a Rennlist sponsor and thus cannot promote his product here. Please contact him elsewhere for info. Thanks!

V2Rocket

My car is all street...but 944's (until maybe 1991?) don't have a CEL/MIL so it's not necessary. I don't need to smog until 2018 but intend on running the VEMS through the test...I expect no problems in the "functional" portion of the CA smog test.

If asking about a later car application...hopefully Raceboy can chime in on that.

What's it to you?
Are you going to buy a VEMS ever? Or just keep the drive-by questions coming?

blade7

I'll keep asking the questions , if you keep up with the theory...

I'm running VEMS on my 87 951. The plug and play portion is straight forward but you do need to know what you're doing; it's not just swapping a DME.

My car is a very low mileage (23k miles) example where I wanted to upgrade performance for improved track (DE) and street use while being able to return it to OE spec down the line. As I upgrade, I wanted to not need to dyno tune with every change. I've changed injectors and waste gate so far and am implementing the electronic boost control with the VEMS software.

I've found the VE analyzer Auto Tune feature within VEMS to be very effective and provide a safe tune. If I was going for peak power, I would still visit the dyno, but my plan is to save that for when all upgrades are complete.

I'm very happy with the product and will likely by another VEMS setup for my other P-car (an S). Raceboy knows his stuff and while there is the delay in time zones to get answers sometimes, Raceboy supports his customers after the fact. To that end, as I go along with my car, I'm happy to share my knowledge if anyone has specific questions.
