b) there is a deficiency in the curreny product and improvement can be made.
Throw out what you want in your dream ECU/monitoring unit (this goes for everyone not just HDDP).
We can evaluate the specs and go from there.
But be warned, if this goes on as an opensource / hobby, you might not get anything back before your car hits 200k miles.

Here's a promo, though not completed yet, of the new TV show I'm doing about the tuning market... I was sitting here editing it as your message came in... It's not complete, but I have international distribution for the show already...
Sorry to have bothered you...

Just my view on the development time necessary to bring a quality product to market. There is a big difference when you are developing an One-off ECU for your own use compare to developing ECU for the mass market (Quality Control, gov regs, customer support). Believe me, I thought about a startup before.
As building an one-off ECU for myself, that is still in the plans. Too bad this thing call grad school sucking up all my time, along with this car/forum.
As for the show, looks good. Is this intended for syndicated TV? I do recall SpeedChannel has a show call Import Tuners, how did that do?

Re: electric supercharger
Look folks, all this talk about a cheap super charger, why don't you just remove the fog lamps and run your air inlet hoses down into the holes. Duct the air into your engines that way. Install your fog lamps at a different location or just do away with them until you feel a need to reinstall. The location of the inlets would be right out there in the front of the car, you would get max ram air induction, the faster you drive the more pressure. The way your going with this fan motor, kinda sounds like something running inside my computer. hooah

But if you find a frontal cross section area larger than 3" then you are in business.

However, my original question about the partial throttle opening and increase air flow has more to do with the efficiency of the combustion process. If we were able to increase the air density slightly at 1/4 throttle how does that fair against 1/4 throttle naturally aspirated?

Question/answer #1,
Actually, if you don't have access to the power enrichment tables in the Engine Management Computer about the only thing you can do is increase fuel pressure with a variable fuel pressure regulator. Take the car to the dyno and make a few runs with a wide band O2 sensor in place. You would adjust the fuel pressure regulator until you got about 12.7:1 air fuel ratio for max performance. This only affects WOT (wide open throttle or Power Enrichment mode).
Question/answer #2,
If I understand the question, 1/4 throttle would be restrictive enough to maybe allow 100 cfm to pass into the plenum. If you tried to force a little more air at 1/4 throttle maybe 150 cfm the engine would initially lean out then the O2 sensor would detect a lean condition and ask the BLM (block learn mode) to update the volume metric efficiency table. RPM would pick up.

Re: electric supercharger
Guys, since we are on the subject, I have a very good friend that is quite knowledgeable when it comes to the CAN (Controller Area Network) buss that our XF used to communicate. I will ask him if he has the ability to hack into the computer. I think he told me that he already has but did not know how to access the data. Maybe we can get some of our European buddies to help us here.
For anybody that finds performance tuning interesting go to this site. It is geared toward GM cars. I use this software.

Re: electric supercharger
Wayne: you're a wealth of knowledge... Thank you for sharing on this subject. I'm really looking for engine management software that I can use for the car... I need every advantage I can for this little underpowered car that is now classed in SCCA T3.
Obviously the programs are available, otherwise PowerChip, Upsolute, etc. would not be able to offer an upgrade... We just need to find those files...

They may have hacked the software, or purchased the program from someone... Either way, it's available... We just have to find it...

Re: electric supercharger
One thing I'm wondering is how standardized the computers are. My mentor once told me that ECM's, PCM's and OBDII computers were all basically the same among most of the models. I wonder if in order to sell cars in the USA the Europeans have to use a standardized OBDII computer. FYI, a single scan tool will generally scan a number of different type cars, foreign and domestic, which indicates to me there is some standardization. Maybe some disgruntled Mercedes employee will step in here and spill the beans and then my spoiler won't tell on me until I hit 80 mph. Ha
Re: electric supercharger
I'll check it out but they're not going to cut their own throat and give out proprietary information. BUT, if some propeller hat on this forum could take one of these scan tools and trap some of the commands that would cause the computer to spill its guts we would be heading in the right direction. Also, reading data tables and actually changing them are two different things. I think I may be getting into an area here where I may be more dangerous than effective.

I have talked to this guy before and he is a super dude and may be able to answer some of our questions. I also have a copy of his software. It is free and you might want to download a copy just to inspect it.

Re: electric supercharger
I think I'm going to buy the Super Eram for my 90 Porsche S2. Thats 1.7 psi of boost which going by their dyno charts comes out averaging to about 10 hp minimum. Not bad. I know people will make fun of it but these guys have been around a long time and have quite a bit of good testimonials plus a couple of magazine reviews with dyno charts.
Heck, at least they provide dyno charts. What about all these rip off chip manufacturers and cone filter rip offs.
I'm going to try it on the Porsche and let you know how it goes. If it works, one of these is going in the Xfire for sure.
