Re: Port Injection 2.0TFSI

It depends on your Fuel Pump 1 PWM Control -> Output Drive Type and what your controller expects. I see a lot of PNP kits have this logic where the Drive Type is set to Low Side (meaning 100% PWM pulls to ground), and then the control is reversed (ie. lower duty, more pump). I don't know why it's do...

Re: Recommended Parts for Water Meth Injection setups

Interesting, was just about to start working on the WMI setup and have the Aquamist flow sensor. Is there a good alternative sensor for high pressures? Would be interesting to understand if there are chances of getting this working with PFM without HW changes to the WMI controller.

Re: Haldex controller in PQ35/MED9.1

Sorry, I missed that part. I haven't yet put mine into the car (TTRS 8J), so I don't know if anything will be needed with that platform. If you end up solving it, please post the solution here for future reference.

Re: Haldex controller in PQ35/MED9.1

Reach out to support@syvecs.co.uk and they will send you custom FW and you'll have to select the appropriate Car Code in the map. I thought the FW was the same as the one on the site here, but appears that it is not, as the size doesn't match.

Re: Recommended Parts for Water Meth Injection setups

Anyone know the wiring of this:
https://aquamist-direct.com/806-567-rep ... sor-cable/

It's a 4 wire hall effect sensor. I'm assuming:
Red to +5V
Yellow is signal to one of the freq inputs
Black and blue not sure - one is definitely ground, but what's the other one?

Re: Fuel Pressure Dip - Deutschwerks Fuel Pump - PWM Ctrl

What ECU do you have? Post your calibration or at least the relevant fuel pump tables.

Re: Exhaust valves won't stay closed bug

If you are looking for official Syvecs support, this is the wrong channel. If you want community assistance, we'll need to see some maps, logs that log the duty to the valve, etc.

Re: Exhaust valves won't stay closed bug

It's hard to say anything without the logs - the PWM duty that goes to the valve needs to be logged. It would also be useful to see the calibration, since this sounds like a time-based event changes the duty, like temperature, runTime, etc. I have the 8J TTRS and have no issues with this. There's a ...
