VEMS Plug-n-Play - quick review

[v2rocket_aka944]

Just needed to get the right bracket from a late car to attach the ICV to the engine, under the intake, and make some custom hoses.

Bumping this up.

Can someone give me a general step by step on how to get this system installed? My kit arrived but there's almost no guidance or instructions included at all.

Do I need to use a computer to install? Can I literally just plug stuff in, install the various sensors and fire it up? I'd rather not have to use a laptop to do anything, as I assumed this was literally just plug-and-play.

Thanks

where stuff plugs in should be pretty self explanatory. mine came with labeled wires but if you really need help add photos of what you cant figure out.

it will likely start up after just plugging in but yes you will need your laptop and tuning software to dial in the tune, every car is different and the tune that comes with the ECU is 85-90% of the way there. not a lot of work but some tweaks might be needed.

I was hoping to just use the auto tune feature ... I'd rather not mess with any tuning. I figure let it idle for a while, then a nice easy drive for a little bit, then start to get on the throttle for bit, then some WOT pulls.

[v2rocket_aka944]

Autotune does the work for you but it does take a good amount of driving time in each state idling, WOT, cruise, etc to nail it down.

There is not an ECU available for the 944 that will just work out of the box like newer OBD2 stuff.

Autotune works but obviously has to be enabled via tuning software. I sent you all the instructions needed, there are links to very good tutorial videos.
Just follow the steps and it will work. S2 tune that came with the ECU will be running very well out of the box but you still need to install at least TPS and wideband lambda sensor.

Hi everyone!
So, I ordered VEMS ECU from https://www.pnpecu.com/vems-porsche-924s944-25-8v-na-143... in late summer of 2021 and received it in winter of 2022, but I've just managed to install everything after such a long time due to some personal issues.
So, all my fears and anxieties came true... First of all I had to find a Bluetooth pin to connect my laptop to the ECU and luckily I found it. It's '9111'.
I calibrated the WBO2 sensor properly (I had to take it out from the exhaust pipe, because I didn't know that it needs to be calibrated in a free environment). Then I calibrated TPS... And started the car.
It runs very bad and very rich.

So, I have a few issues to resolve:
1) Am I missing a base configuration file for my car? Where can I get it? Can someone help me with that? It's a 1987 Porsche 944 NA with stock engine without any modifications. I'm running these injectors, but they are like stock ones - e b a y. c o m /itm/371875675242

2) The analog tachometer on the dashboard doesn't work anymore. Is there any wiring problem on the VEMS ECU side? It was working just fine with the stock ECU. I found these settings somewhere in the web and tried them, but they didn't do anything (see the picture for the reference)

3) VEMSTune application crashes randomly from time to time. So, it's a bit annoying �� I installed and using the latest version:

4) It seems like VE Tune by statistics and Live VE Analyzer tools don't work for me, because I'm getting this weird error: "Filter Failed!" Not sure what it means. So, I can't use the Auto-Tune option.
Please see the pictures of the setup and how bad the car is running for the reference.
So, at this point I'm pretty frustrated because the car is just stuck on the driveway in front of the garage and I'm desperate for any help or guidance. Would anyone be able to answer the questions above or redirect me to anyone who can help me to configure it and finish the tuning?
