RE: [DML] EFI Conversion Kit



Just out of curiosity... what "Idle air blocks" are you using? (Pic?)

Bill, it would certainly improve your credibility if you were to check your
facts first and converse with those individuals whom you seem to wish to
disparage. 

Owen does not have a problem. Owen does however have purchase-ready fuel
rails, hold down brackets and idle air control blocks should anyone in the
community wish to purchase them to convert a stock car to EFI. We also have
a bill of materials and lots of pictures. Detailed instructions are slowly
but surely coming along. I am not actively marketing any of this, nor as you
can see, trying to promote the conversion to EFI for anyone not willing to
invest the necessary time and energy in educating oneself. I do not try to
mislead anyone into believing this is "plug and play" and I have no desire
to hold anyone's hand. I am however fully willing to help those that wish to
help themselves. I learned from others and am trying to help the next wave.
The ONLY reason I can get these parts for people is that we had to carefully
measure, cut and refine each one to make it fit. We therefore have the final
measurements and can save others the "joy" of fabrication. We standardized
it.

As Shannon eloquently pointed out, we appear to have identified an issue
with a supplier's product. They are currently working with us to resolve the
issue. As stated, MY unit is working just great and has run both of the
prototype cars too. As it is, both of them have been driving around and
perfecting their tune, but with the limitation of the box losing
synchronization with the distributor >3,500 RPM, it cannot be considered
"done". In the meantime, users can simply buy a 3.0 generation board. 

And to set you straight again, MY tune fired right up on Shannon's car.
EVERY car will require fine tuning, but one of the super nice things about
TunerStudio is its VE analyzer that basically allows you to drive and it
self tunes. That is assuming the user is both smart enough and motivated
enough to understand the concept of target air/fuel ratios. Likewise, unless
you have the ability to grasp the whole issue of timing advance, stick with
the conservative stock setup. THESE tables are absolutely 100% copyable. 

Your information on interpolation and table sizes is also wrong. You can
have 12x12 or 16x16 true enough, but YOU fully control the scale on the X
and Y axis. That means if I want a lot of detail between 700 and 2000 RPM, I
can have it. You really only need a single value at both 5000 and 6000 and
the software interpolates between the two. So at the end of the day it is
not a linear table. VERY powerful.

In the vein of continuous improvement I am always tinkering with the new
features and trying to find even more performance from the stock car. Yes,
sometimes it doesn't work and I either reload the previous tune or simply
autotune it again. Development time as you call it, ended a long, long time
ago.

I haven't been exiled from the DMCtalk boards and choose to communicate
freely, positively and openly in those forums. I only joined this board to
set the story straight. Anyone that wishes to respectfully learn, share or
just watch is welcome over there. 

Bill, I've never had a personal problem with you and in fact some of your
ideas have made their way into my car. If you would like to pass commentary
on what you think you understand of the technology you have chosen not to
employ yourself, so be it. Do me the civil favor of leaving my name out of
your running commentaries.

taken over to the M/S forum where you can get more experienced help specific

advice, this is a Delorean forum where we can help you with the stock fuel
system. Perhaps a forum could be set up just to deal with engine conversions
and engine modifications for the Delorean.

important. Short of providing a kit, a Bill of Materials would do but then
you give the person the chance to substitute or change things. Production
cars are close enough so it all works and the software has some adjustablity
to compensate for the minor variations in each motor. If you are trying to
find reasons for people to NOT convert to EFI, many of them apply to
changing to a carburetor. For all of the effort a properly done conversion
will take, IMHO it is easier to try to fix the K-Jet and get it running
right. As for downloading a fuel map, I am sure one could be created that is
wide enough to get you running and then each individual could fine-tune it
(or not). EFI keeps improving all time. I am sure eventually this could
become more automated and easier to do. In the meantime the K-Jet has been
optimized to work well on the Delorean (when it is working right).
