[Shotimes] LPM Help - Ted B.

[T. A. Breaux]

The LPM is a tool that is capable of effectively enhancing the performance
characteristics of a SHO.  Unlike most other performance hardware, the LPM
provides the ability to adjust parameters to suit the needs of any indivudual
car.

The potential to which an LPM can be used to influence the performance
characteristics of any SHO depends on several factors, one being the condition
and integrity of electronic and mechanical equipment on the host car (which is
not always easy to determine).  Likewise, the performance potential is
governed by the ultimate ability of the hardware (including mods) to support
this.  What this equates to in real numbers varies (widely) from vehicle to
vehicle.

If one is serious about performance, dyno tuning is very helpful.
2000-7500rpm runs with A/F logging is particularly useful.  Since even bone
stock SHOs can display power deviations upward of 20hp, comparing the results
of any individual car with that of another can be confusing/misleading.  As
far as the reason for the deviations, this is due to Ford's sloppy QA/QC and
some 8 years and many miles under the hoods of even the newest SHOs.

Some say the LPM isn't useful on mildly prepared cars.  If a car doesn't
respond well to certain changes, that isn't necessarily due to shortcomings in
the performance part or device.  Fairly recently, I've assisted in dyno tuning
a typical SHO with 80mm MAF, UDP's, Y-pipe, Sho Shop Cat Back and LPM that
peaks right at 212hp and 196ft/lbs at the wheels.  We were able to gain quite
a bit of torque down low and improve power across the board via the LPM.  It
may be of interest to know that despite the fact that I was able to tune this
car effectively, I have never even seen the car in question (all done
remotely).

Do all cars respond this way?  Some do, some don't.  Of course, with an LPM,
you have 30-days to evaluate it, risk free.  Try to do that with other
performance hardware.



Regarding Bruce and Chad.....

My programming computer is used solely for that purpose.  No viruses there
(although it is checked regularly).

Bruce's unit is an older one that he purchased used.  Unfortunately, it may
have been damaged at some point.  We are not certain at the present.

Chad's unit is a new one.  We are trying to determine if the unit is at fault,
or if he has a weak ECM.  If the unit is at fault (a rare occurrence), he gets
a replacement.
