Grim speed boost control valve

I was wondering if the GS boost control valve for the geni would work on other kia's and hyandai's on VW's they use to run the boost control valves of an Audi that did the same thing the grimspeed one does . It's basically a plug and play part . Automotive lighting Camera accessory Font Cameras & optics Cable

Ours is a 2 port valve which really isn't a big deal, would just need to find something to keep water and dirt out without blocking it off (will still need to vent pressure from the actuator diaphragm). The second thing to do before hooking it up is get a ohms reading between the two wires and compare it to the stock one. If the ohms are to low it will not only react slower but could also damage the ECU and to high or low and the ECU will read it as defective and set a code (tried using the Greddy valve).

You used the Greddy directly ? I would expect that one not to work because it's mad for the Greddy units only . This is for stock plug in . But your advice is really good . I thought we had a 3 port I need to recheck mines again . If I can get a hold of a optima solinoid or better yet a geni one I could do what you told me . Who knows I may find a cheaper solution just to use an optima solinoid . I should post up on the VW forums about the nj75 difference . It may be the ohms and if I can figure out what the settings are on all three we might have a poor mans upgrade :) unless one of the tuners can figure it out first lol and just collect and sell upgrade valves like the Audi VW guys did with the nj75
There is already a upgraded valve called the "snoopy panda" that is a direct replacement of our solenoid. It is supposed to hold the boost better and be way faster at releasing then the stock. A few VT guys have it but its not meant to give more boost.

Thanks ! Yeah they are not designed or used to give more . What it's supposed to do is hold longer , delaying the signal so we boost at the set max longer. So you would be 17-18 all day long instead of 14-15 with spike 17-18. It even works better with tunes

When I was stock I would boost daily 18psi and peak at 20 but quickly drop to the 18. I emailed the company to get more of a explanation about his solenoid for us. I will post his response when I get it. I know some guys on the VT site say they love it and works way better then stock. For the $125 it's not a bad idea and you can run a HKS BOV on it along with others because it has the bigger ports and responds faster to. I am thinking about getting it but I need to get a fuel line first.

I have to look at my fuel line . I read they did a recall slash update for both cars on the lines . Not sure what was done as far as material. . But I got to look at mines because it's a 2016 . I know I was to planning on getting the upgrade as its now available on 6th's site

I will probably be ordering it next week. I am hitting a hard cut and want to get the line done and then sending my ecu back to tork for a update and adjustment for my downpipe he is making
Where did you hear about that recall?

Also snoopy panda has a diy option. You can probably get a solenoid that would work for $30-40.

I'm interested to read more about these. It sounds like the VT guys like them but I can't find much more than "snoopy panda solenoid installed!! Woo"
The recall I know about is for the VT guys and not us yet. Might have to call Kia Monday and see about any recalls
Keep us posted.

Also please buy one of these solenoids and do a write up. Please? For the childrens? It is Christmas time after all...
OK so you are thinking of using the GS Boost control valve for the BOV? Our stock BOV actuator has 3 lines so it might work if the ohms are the same or close. The actual boost control valve that this is designed to replace is mounted down by the turbo to control the waste gate vacuum actuator which is only 2 lines.
I believe it's not really a boost control valve but actually an RCV . Most turbo cars now a days have them . They sense the pressure inside and manage opening and closing of both valves , BOV and WGV, when the manifold pressure reaches desired peak it sends a signal to the actual boost control valve to open the waste gate to release pressure as it also reacts to a closed pressure on the throttle body to open the BOV when the throttle plate closes . I hope a tuner checks on to confirm this lol
That GrimmSpeed product in the first post is to replace the OEM Wastgate control solenoid for the turbocharger, not the solenoid that works for the blow off valve.

You would not use this GrimmSpeed product for the blow off valve. It's designed as a wastegate control solenoid. The advantage to the GrimmSpeed part is it flows air through it a little better, and their unit may have better materials than stock.

Again, it is designed to replace the OEM Wastegate solenoid for the turbocharger.

If you want to hold boost longer, get a 6th vacuum block and do the BOV solenoid bypass mod.

The GS valve is designed for boost control (waste gate). The RCV/BOV/BPV solenoid is located/attached to the back of the stock IC and has 3 ports with Coil Resistance (Ω) 28.3 ~ 31.1 which is also what is spec'd for the Genesis and Optima valves
Lol . I should have looked more on the panda site but I found exactly what I needed for information . You can use the GS to control the BOV . But you have to change the connector . Snoopy panda sells the male connector to do it . But a cheaper option would be buy the male connector and get solinoid valve part #35A-AAA-DDBA-1BA . It can be found as low as 40$ on Amazon
Here is what snoopy panda said about their valve.

The SECo PnP BOV solenoid doesn’t just flow more, but is also the fastest solenoid on the market at 6ms response, that’s twice as fast as the fastest BOV on the market, the Synapse SB, and the only way to make your valve operate the way it was intended on modern, ECU controlled turbocharged engines. The flexibility of having 1/8th NPT ports allows you to customize your engine bay perfectly too, allowing hard PEX lines for zero chance of vacuum collapse and handling boost pressures of 120psi, over 4 times the rated pressure of the PA6 solenoid currently used in Hyundai/VAG applications. While you may never run 120psi in your engine, knowing that it can take that level of abuse means it’s tough as nails and designed to work in the harshest environments.

After reading that on the site , led me to thinking I may be losing stock power because I might be getting some blow by on the BOV because of the same issue it describes . The turboxs tube is bigger than stock and the connector looks restrictive . Stock tubing is also restrictive leading up to the in line connector .
Stock BOV is garbage. It doesn't hold boost well and is prone to rears
