For the techno junkies here is a site for a low cost fully adjustable control of your EFI, separate from your ECM. Would be great for draggin.

Sorry fast fingers slow mind. http://www.bgsoflex.com/megasquirt.html

 

here is another project online for building your own efi system. its still more in the development phase, but looks more technically advanced than the other system, in fact th diy-efi system will proly be more inline with a motec system(seems like they looked closely at one while in the design phase for theirs) There are several projects going on at this site, the one most people would proly be interested in is the wideband afr meter. you can build one for about $300, you just need someone that has the proper soldering tools and skill to solder parts onto the board that you buy of the website. as for the sensor, i have found them for 250. and i think the the rest of the parts needed is about 40-50. i want to stress this is a non-profit web-based design and to view the schematics(which are obviously free) you have to agree to a condition stating you will not try and produce these for profit(this goes for the efi system too). hope this helps. i plan on doing the wideband afr meter, its pretty much developed and they have had many people report good results.
