- A drop in pressure on the vacuum signal line
- An actual drop in boost in the charge pipes which means the drive has to ACTUALLY be off the throttle.
This is the reason the HKS type valves sometimes result in more compressor surge.
There is a slight "blip" in boost when the device triggers but if you keep the foot into it and continue generating boost, the HKS will seal back up. Quote:

First of all, excellent work! Someone told me about this a couple weeks ago, but I'm just now stumbling upon the thread.... better late than never.
CPE fmic/HK$ here as well. However, very interested in how well this works in high boost BT app.... I'd like to run 25psi, and have it set to purge at 27psi... can it get rid of that much air fast enough? I need to upgrade my CPE fmic to a custom TR8 2/ 2.5" pipes, so I would definitely consider changing bpvs (and sell the HK$ w/ the cpe kit) so I could run this device. I'm way too lazy to change the flange/bpv in the meantime, and I'm just running spring +ewg, so I'm not really at a huge risk atm. However, even tho I replaced all my vac line going BT and have nice high temp vac line going to my ewg, that line still makes me nervous, lol. I check it periodically for cracks/etc.... you never know wtf can happen and have it crack/melt/etc and you're fucked. Great invention! I would definitely try to patent it.
Any way to to have use two settings to replace the w/m BCS failsafe some of us run? Like the normal set up to purge at 27psi, but if it gets a 12v signal from my w/m fs, have it only hold like 15psi? Is that what you were talking about with the w/m integration? That would be sweeet! | Thaks Doug! A couple of clarifications. The amount of boost that your system will hold with the device triggered depends on your setup. If the BPV is a push type, it will be significantly less than what you set your setpoint to. On a stock turbo and BPV, it can't make more than ~10-12psi. You will feel a loss in power, see a red LED, and if the valve is recirculated so that you don't lose metered air, the car will continue driving normally without a fuel cut like feeling so it will be safe if you're in the middle of a merging maneuver.
The device can also be triggered via a 5V or 12V signal from any other source such as a WMI or any other controller with that type of output. If it's triggered, once again boost drops, you get the LED, and you know something is off right away.
The system will reset once you're out of boost, so you don't have to pull over or stop driving to be able to drive into boost again normally. You just get off the the throttle. Quote:

Lex, the Synapse DV can be run in either push or pull mode.
That being said, I've had my eye on the XLE anyway. LOL | I wasn't aware of this - I should do a little more reading on this. Once some of the beta testers get their hands on this and do some testing with different setups and valves, I'll be able to share more about specific valves and their performance. |
