  Automotive Component Remanufacturing Ltd
offer an engine test cell service for the tuning
and set up of a non standard, tuned
or performance engine.

The test cell consists of a modified G4 type
hydraulic dynamometer coupled to a 16
channel Dataq computerised control and
monitoring system. This is combined with
a sun SMP 4000 analyser, to allow very close
control and monitoring of engine parameters
throughout the entire test.

Data logging of user configurable parameters
enables the test to be recorded in both
Microsoft Excel and graphical format for easy
reference.

Typically these engines either are engines upgraded from carburettors and distributors
or engines modified from their original specification. More recent engines taken from modern
cars with their complex and integrated systems can be simplified for use in other applications.

* Mount engine to dynamometer, where necessary manufacture mounts and brackets.

* Fit engine sensors, wiring loon and programmable engine management system
such as omex 500 or 700 series fuel and ignition EMSs.

* Run engine at every load and RPM to map optimum fuelling and ignition at each point.
Set up secondary functions such as shift lamp, fuel pump control warm up maps etc.

* Provide full data log of entire test, power and torque curves copy of EMS calibration
and where required soft ware, cables for user access to the EMS.
 
   
 

Many race and performance engines still use
carburettors and distributors as do historic
and classics. A typical test session will enable
fuelling and ignition to be optimized for
maximum performance typical test as follows:

* Mount engine to dynamometer, where
necessary manufacture mounts and brackets.

* Run engine to calibrate fuelling and generate
optimum ignition curve. Distributors can be
recurved to suit engine if required.

* Set up secondary functions such as idle
mixture etc.

Diesel and LPG engines are also covered.
For popular engines such as Rover V8s we
offer package deals. Please contact us for more
details or to discuss your project. The engine
test service is backed up with a modern
machine shop and engine build facility.
