Exclamation Hey guys, question for ya.. (DSI Controller)

If I made up a kit to control the Dual Stage Intake (DSI) Manifold for ANY Rpm (800-9800 capability) would you be interested? Cost would be about $175-200.

I'd like to get some feedback before I really get into it...

Mine was a PITA to do, (lots of time and money to figure it out) but it was worth it in the end...able to move the power curve up or down, could go well with cam gears and other engine tuning that changes the power curve.

Just wanted to get some thoughts from you guys before I start tearing my car apart for R&D purposes.

BTW, all parts I make and sell are ALL tested and used on my car...

Post Info on the SVT DSI Controller -

The kit will include:

-Window switch, adjustable from 800-9800 RPM.
-Relay, driven by the window switch to activate the control for the DSI
-FRPP Tach Driver, so everything is intune for RPM Settings
-Switch, so you can turn the DSIC on or off, thus, allowing you to use the factory setting, and then you can turn the DSIC on for race use.

If you have mods (ie, cam gear) where adjustments are allowed, you can fine tune the DSI for maximum power.

The ONLY thing I'm working on, is a CEL...sometimes I get a CEL from breaking the signal and using my setting. I guess the ECU see's there is a malfunction in the DSI module. Simply driving a few minutes turns the light off, or you can unplug the battery for a few minutes. Im trying to make it so the ECU still thinks the DSI is under control of the ECU. OBD2 is a PITA to deal with and doesnt like mods too much. Just wanted to forewarn you for anyone that may be interested. I *THINK* I might have it figured out, and once the rain lets up and I can play with it, I will....

The DSI kits should be ready to go in about 2-3 weeks!

Sounds like it's a good idea.....how much does it help you on the track or dyno?

I havent dynoed just yet. I'm waiting to get a couple odds and ends done and I will get everything in tune. I want to get the cam gear tuned to peak hp, and then tune the DSI to work with the gear. Before YRFO, it was unbeleiveable!!

sounds awesome. It might be another mod my father would be interested in as he plans on making his SVT into an RS clone over the next three years. With all of the mods he is planning on running he could probably take advantage of something like this.

Well, you need that box..with the cable. My unit controls when that box works the solenoid.

Also, one thing I realized today, its adjustment only goes as high (in RPM) as you current ECU Flash. If you have an RLA flash, your adjustment is 800-6000, if you have YRF0, you can control the DSI for 800-5000. Thats not so bad if you want to tune for mid-high end power. As you tune this along with a cam gear, you can make it go in sinc. and you get a race mode (DSIC)/ street mode (oem setting). NOW! I could be completely wrong...if it'd stop with the rain, I could find out for sure...I might have that 800-9800 RPM adjustment!!

Well, I voted NO....but you gotta hear me out. I congratulate you on taking the time to do something creative, and I think the kit would be very useful. However, coming from a 'marketability' standpoint, I'm unsure how well it would go over. Reason being, for that kind of money, you could put that towards an SCT/Predator and then the tuner would have control over it.

So, if you have the money and like to tinker, this is awesome. I just think that if you were to do a mod that the DSI would affect (like cam gears), you should let the tuner adjust it all on the dyno anyway. Just my $0.02.

Once again, good job on this!
