      Uh, right. Yeah, that is NEVER going to happen. A set of throttles alone costs more than a short runner intake manifold.

Need to dig a closer picture out of my phone, but you can just see it tucked under the intake tube tucked against the firewall. .
      Ah, yes! I remember looking into that. So, it all worked out well or "well enough"? Did anybody protest your unfair advantage? Please get us some close up shots that reveal the deep and dark secrets.

      .......one day..........it'll happen I am curious to see dyno graphs of what this mod has done as far as the torque curve goes.

      This is pretty cool. lots of throttle blade area so it would get better the bigger the engine requirements.

      Well, get on it immediately. If you can supply us with a $700 drop-in ITB kit for CIS, we'll commit to a 50-piece production run.

      If our old man customer is interested, we'll do it. Again, this is more a proof of concept and "because we can" than an unveiling of new product line. There's probably 50 CIS kooks out there that'd love this... but want to spend $200 on it. The juice has to be worth the squeeze.

      CIS is great until it can't do what you want. It has the innate ability of limiting your airflow to what it can fuel. It's beautifully simple that way.

      Many, many moons ago I hacked the MS code to handle my CIS lambda valve (needs fixed freq). Totally computer controlled AFR on the stupid cheap. CIS-E would be harder to hack with how the CPR works.

      Interesting idea, but I would argue that an EFI conversion and stock intake would likely drive better and make more power. But to each his own.

      It actually worked well, once we got beyond our own learning curve of making programmable control work

      Never an issue with legality. We were open about what we were doing with the rulemakers and have told other competitors what we did. We also realized after making it work that no one in their right mind would ever even try this, and we asked for an allowance for all fuel injected cars to switch to electronic injectors, otherwise you would not see any VWs that only came with CIS other than this one racing in this class.

      So - next year we can swap the injectors and turn the fuel pressure down a bunch.

      Scott,
      This may be of use as a simple way to tune proper fueling and quick response fuel for your CIS setup. Scientific Rabbit is developing this wiring harness for CIS k-jet injection to be controlled and tuned by a wideband O2 & controller. I have this on my car now with the high quality wiring harness they built and love it. They don't have it listed on their site yet.
