Almost finished! VEMS Plug and Play ECU for 951!

[Raceboy]

Here's something for guys who don't want to disclose that they run something modern as engine management: VEMS board fitted inside Porsche 944 NA Motronic DME case! Only with some extras like integrated wideband controller, knock sensing, EGT controller and integrated Bluetooth connectivity. 250 kPa MAP sensor is external, residing in the hollowed out AFM casing. Totally stealth!

Getting ready to install mine, Peep, sent you a pm.

So how do I get one of these "stealth" VEMS? I'm on the fence between this set up now and m-tune or speed force racings stage 3 maf! How much shipped to Mew York?

Peep do you have an "exchange program" for original VEMS units to swap to the stealth style...

[Raceboy]

Sadly no Stealth units are ordered quite seldom, maybe just 1-2% of the customers want stealth unit.

But perhaps we can work something out..

Positive reviews are coming for PnP VEMS and Raceboy from the UK. So it's only right I take back my negative comments from 2 years ago.

[Raceboy]

Well, we all jump to conclusions sometimes too quickly. Thank you and I take back my negative comments also.

Quick question, on my way to going with raceboys standalone this spring. Just ordered a full 3 inch exhaust to get rid of te cat. And next I’m gonna upgrade the wastegate. Which one should I get. The LR duel port? Or the tial? I’m very new to all the older turbo stuff with boost controllers and external wastegate and what not. Does the “boost solenoid” he sells with it hook up to the wastegate itself? Do I need a duel port on to hook it up? Just trying to get my parts in order by spring. Thanks guys.

[Raceboy]

You can hook the solenoid to eiher single or dual port wastegate, works with both types.

[derek.kritz]

Cool. Does anyone know where to purchase the tial 38 with the adapter plates? Do they needed to be welded on or would the bolt on type be ok. Try sell the kit on eBay. Bolt on. SFR also sells it with the adapter kit. Would it bolt up to the stock pipes?

[commdiver]

Tial 46mm on eBay already for the 951 that’s the one to get

Well after a bit of a delay my VEMS shipped today from Estonia. I look forward to the install and will post up my results here.

Specs for my car, 3.0L Alusil 89 2.7 block and head, GT3582, custom 3" V band exhaust. I'm using #80 Deka injectors.

Peep was kind enough to load his tune for the Deka injectors and 18psi wastegate control for me.

Here's the dyno sheet from couple of years ago. I was running the Mtune and the car had a slight misfire above 5k. At this time I was also running a LR65 turbo.

arrived yesterday!!

Raceboy, do you know the size of the air temp sensor threads?
