7591. All serviceable goods must be packaged securely with

proof of purchase, RMA number, with all shipping charges

prepaid and shipped to PLX Devices Inc. Goods returned

under warranty must be received by PLX Devices Inc.

within ten (10) business days aer the RMA number has

been issued. Goods received aer this period are subject to

fees for the service of repair or replacement. All repaired or

replaced items shall be warranted for the remainder of the

original product warranty.

RETURNS AND RESTOCKING FEE

All returns must be within 30 days of receipt. A 15%

restocking fee may be assessed to applicable PLX Devices

products for refund. All returns are to be packed in original

condition including packaging, documentation, manuals,

and accessories. Returns that do not include all the acces-

sories and components may be returned to the customer

or charged on a per item basis. e customer assumes

responsibility for product until receipt at PLX Devices Inc.,

shipping via an insurable carrier is recommended. Any un-

authorized shipping charges will be billed to the customer

or shipment will be refused.

8. Users guide

Troubleshooting:

Upon power up, the WB analog output should read 2.30V-2.40V with the O2 sensor disconnected. With

the O2 sensor connected and exposed to free air, the WB analog output should read starting from 2.3V

climbing up to 5.0V within 30 seconds. If both conditions are met, your SM-AFR is properly working. If

the sensor does not reach Lean/Air within 45-60 seconds, please replace your O2 sensor. Replacement sen-

sors are available from the PLX Online Store under accessories.

1. e output is not showing the correct AFR readings:

A. With the O2 sensor harness disconnected, at initial power-up it should display between 14.6 and 14.7

(wideband analog voltage: 2.30V - 2.40V).

i. If it is reading below 14.5, please verify that the unit is receiving at least 12V and you have at least a 5

amp fuse. If it is still reading below 14.5 even with the correct voltage, contact [email protected] and

request a RMA number. Your unit is faulty and needs to be repaired.

ii. If it is reading above 14.8, contact [email protected] and request a RMA number. Your unit is

faulty and needs to be repaired.

B. Reconnect the O2 sensor with the sensor harness, with the O2 sensor exposed to free air. During the

30 second warm up phase, the voltage should increase from 2.35V to 5.0V.

i. Voltage does not read 5.0V even aer 60 seconds:

a. Try another power source for your SM-AFR.

b. Verify that a fuse is installed rated no less than 5A.

c. Check connectivity of harness and O2 sensor.

d. Your O2 sensor needs to be replaced.

C. When the unit says AIR*, blow on the O2 sensor. e display should show LEAN*.

i. Display does not go to LEAN*:

a. Your O2 sensor needs to be replaced.

* will only show “LEAN” or “AIR” on DM-6 Gauge

Compatibility with Other Fuels:

e above graphs assume that the device will be used with gasoline (14.7). e SM-AFR is also

compatible with the following fuels: Diesel (14.6), Methanol (6.4), Ethanol (9.0), LPG (15.5),

CNG (17.2), E85 (9.7). To nd the new relationship of AFR to output voltage, simply multiply

the lambda value by the specic fuel’s stoichiometric air/fuel ratio.

Example: If your engine uses methanol instead of gasoline, the conversion will be as follows.

1) Divide the AFR value by 14.7 (gasoline) to obtain a lambda value

2) Multiply the lambda value by 6.4 (methanol)

Lambda 0.68 0.80 0.90 1.00 1.10 1.20 1.30 1.36

Gasoline 10.00 11.76 13.23 14.70 16.17 17.64 19.11 19.99

Diesel 9.93 11.68 13.14 14.60 16.06 17.52 18.98 19.86

Methanol 4.35 5.12 5.76 6.4 7.04 7.68 8.32 8.70

Ethanol 6.12 7.20 8.10 9.00 9.90 10.80 11.70 12.24

E85 6.60 7.76 8.73 9.70 10.67 11.64 12.61 13.19

LPG 10.54 12.40 13.95 15.50 17.05 18.60 20.15 21.08

CNG 11.70 13.76 15.48 17.20 18.92 20.64 22.36 23.39

display modules.
