Source for LH-Jetronic info?

[Michael McBroom]

Hi folks,

I'm a new subscriber to the list, and am looking for the "definitive
source" for information on Bosch's LH-Jetronic efi system.  I've visited
the diy_efi website, searched the archives, and have secured the names
of a few titles.  I'm wondering, however, for those of you who may be
familiar with them, how they compare with Probst's _Bosch Fuel Injection
& Engine Management_ (Bentley, 1991)?  Probst's book is well-written and
easy to understand, but does not go quite to the level of detail I was
hoping for.  I suspect, however, that any further level of detail which
I may seek must be at the application-specific level.  In my case, it's
for both an '87 Volvo 740 turbo and an '88 Volvo 760 turbo.  I'm
interested in finding out how LH-Jetronic is employed on other
platforms, too, though, such as the Porsche 928s, Saabs, and a couple of
the big Bimmers.

The '740 turbo is a project car currently undergoing enhancements.  I've
been told that the stock efi system, with the addition of a rising rate
pressure regulator, will provide sufficient fuel delivery for horsepower
applications up to 280.  Beyond that, supplementary components would
need to be employed, such as a fifth injector.  If I were to find this
car running shy on fuel (which I doubt will happen, but who can say for
sure?), I would prefer not to go the 5th injector route, and would
rather size the system up a notch or two, if possible.  In order to do
this, though, I'll have to gain a better understanding regarding some of
the particulars of LH-Jet, such as MAF sensor flow parameters and
limits, recalibration possibilities, possible reprograming of the PROM,
etc.

Any advice would be appreciated.
