Computer configuration as a function of the gearbox type17
F3R engine
To check that storing has been correctly carried out, turn the ignition on using fault finding fiche n° 27, bar-
graph 20 LH side should be extinguished, bargraph 19 RH or LH side should be illuminated.
There is a method for configuring the computer which does not require the use of the XR25. To do this:
- turn the ignition on,
- start the engine,
- accelerate the engine to a speed greater than 2500 rpmfor 10 seconds,
- turn the ignition off,
- turn the ignition on again and start the engine,
- accelerate the engine to a speed greater than 2500 rpm for 10 seconds,
- turn the ignition off.
The memorisation procedure is the same as that described previously.
NOTE : the configuration procedure using the XR25 may be used to reconfigure an incorrectly configured
computer (automatic transmission instead of manual gearbox). The procedure which does not use the XR25
will however only work for an unconfigured blank injection computer from stock.

AUTOMATIC TRANSMISSION COMPUTER CONNECTION TO INJECTION COMPUTER
"Park"/"Neutral" position and torque reduction information.
These two items of information are sent on one track of the injection computer.

Torque reduction changing down
Torque reduction changing up
1.In the "Park" or "Neutral" position, you can check whether the voltage, measured using a voltmeter
between track 7 and earth is actually approximately5 V.
As soon as the "drive" (or "other") position is reached, the voltage drops to approximately 0.
2.From the "drive" position and while driving, the automatic transmission computer sends:
- a long pulse for changing up a gear,
- two short pulses for changing down a gear.
The injection computer, in both cases, to smooth the gear change, retards the advance by 25° compared
to the initial advance, for the complete period of torque reduction if the vehicle speed is greater than 6
mph (10 km/h).
The advance returns to the initial setting:
- at once for changing up a gear,
- progressively for changing down a gear.1
