explosive fuel under pressure, electricity and considerable heat. Inside the combustion
chamber, this is a happy combination. In the garage, they are not. The same kind of danger
exists when working underneath a jacked-up car. Please be careful.
5) Electromagnetic interference (EMI) from unsuppressed spark plugs and leads can cause the
ECU to fail. Please do not use them.
6) In hot climates, or with turbocharged engines, y ou may need to employ heat shielding to
prevent heat soak and damage to electrical and fuel p arts. Use the coolest surfaces of the
chassis as a heat sink for components and use thermally conductive brackets where
appropriate.
7) We recommend having your system tuned by professionals. An exhaust gas analyser and
fuel pressure meter make tuning easier and help avoid potentially disastrous lean conditions
that could destroy your engine. Should you wish to tune this unit yourself, make sure you
have some reliable means of determining whether your engine is running lean, Haltech offer
the Haltuner for this purpose. The Haltuner is an inexpensive air-fuel ratio indicator that
gives a full-scale deflection from rich to lean over a display of 30 bar segments. It is
compatible with all O xygen Sensors that output a 0-1V and can be configured upon request
for other sensor ranges. If used in conjunction with a Haltech O xygen Sensor, the Haltuner
will provide air-fuel indication for a range of 11.5:1 to 17:1.
Note: In this manual, reference will be made to M AP
(M anifold Absolute
Pressure - as in MAP sensor) and the fuel maps stored in the ECU. Both are
common industry terms, with entirely different meanings.
