|WHAT THE ENGINE TUNING
PROGRAM KIT DOES.
The program kit is split into 2 parts: firstly, text and pictures with
a full and easy to follow explanation about what is needed to modify an engine to make more power, and
secondly, the computer program which allows you to find the exhaust,
transfer and induction timings (opening, closing and total duration)
using simple measurements from the engine. The computer program shows many
other things too, such as compression ratio, trapped compression ratio,
blowdown, and allows you to input different squish clearances and
combustion chamber volumes and see the difference in compression
Modifying an engine to have more power AND have
good throttling and torque is not easy, but this program will help you do just
that. It allows you to log all the port timings from your engine, based on
easy measurements that take just a few minutes to complete. Once this
information is logged into the program, the port timings etc. are displayed,
and then you can follow the detailed text showing you what can be done to
improve the engine. There is detailed information on all sizes of marine
racing engines (CMB, Picco, Rossi, OPS, Novarossi etc) and also on sport
engines such as SC, Irvine, ASP etc. If you have been trying to
modify engines and have been unsuccessful, this program may help you
retrieve that liner/piston which doesn't work. It will also show why a new model of engine from a manufacturer
may not work in the same way as the old model. Small changes in port timings can
dramatically change the power characteristics of the engine, and these can
be documented here. There are other programs around that are OK for
logging the engine data, but this kit logs the necessary information and
then tells you step by step what to do to improve the power output of your
engine. Included is a step by step description of the modifications
done to one engine as an example. No degree wheel is needed.
The instructions are very
simple. Within minutes the program will generate a list of data
relating to your engine, which you can then compare to the timing lists in
the program. If you have tried to modify an
engine and now it does not throttle, or does not want to keep on pipe
through the corners, this program will show you how to retrieve that
situation. This will easily save you the cost of the software by
helping you to use the cylinder that you modified too
WHAT YOU GET.
1. Software and detailed instructions on
how to use it. Step by step instructions including diagrams
and pictures for measuring
the port timings, compression ratio, and rpm of
your engine. A degree wheel is not needed. You need to input
some basic engine dimensions and simple measurements taken from the top of
the cylinder liner and the software calculates and lists exhaust,
transfer and boost timings, induction port opening, closing and total
duration, (this is for disc, drum or crankshaft induction engines)
blowdown, geometric and trapped compression ratio. The program shows the
effect on compression ratio of changing the exhaust timing, and after
removing or adding head gaskets and/or machining the head. The
software is suitable for engines from .12 (1.8cc) to
50cc, all engine makes from the tiniest OS and SC 1.8cc to Mathe
35cc. Induction types catered for are crankshaft induction,
drum valve, normal disc valve and zimmerman disc valve. Zenoah engines
have their own special program.
2. Complete kit of parts
is included for measuring head
volume and parts needed to show squish clearance.
Full instructions are included on how to modify
your engine for more power and/or better throttling.
Full instructions are included on how to fix
that engine you have modified and which now doesn't want to throttle or pull away from
5. Full backup with any questions answered
within 24 hours.
6. Buyers will be registered and will
receive free updates via email as they are available.
To get you started, there is a standard and a modified engine in 3
engine sizes shown in
If you have been afraid to change
anything on your engine, then this program will make it very easy.
