Title: OBD lesson
Post by familyguy on May 14^th, 2009, 10:23am

Hi guys

I have a lead and software off alex p and i was just wondering if some one in my area would be good enough to give me some lessons in its use and how to read the data maybe over a beer or 2?

In the telford area and would be happy to travel to a meet for the help.

No probs with the mech and elec side of a car as i am an engineer but the diagnostic side is new to me.

thanks

gareth

The pages on the main site detail the use of Alex Peppers OBD software quite comprehensively and you can play around with the sample files .

The OBD PAGES ARE HERE (http://www.fordscorpio.co.uk/homediag.htm) and I hpe that is of some use to you in getting it up and running.

hi there

yep, takes a bit of getting used to it.

easy way is to run a couple of scans.

you need to scan the following...

RPM
MAF
LTFT
BOTH LAMBDA SENSORS
run these for 5 mins at idle (a/c OFF). every minute, blip the throttle to 2k rpm. end this scan.
then do another scan, switching on and off various temp sensors. also check the tps with the engine off (ignition on). should be from 16% to 92% ish.

try not to drive it on the scan.

oh, check the box with auto re-connect under the GATEWAY, PROTOCOL tabs. that way it should continue to scan even if you need to re-start the engine.
