simonpelly Posted June 7, 2023 Share Posted June 7, 2023 HI Folks, Finished fitting a new timing belt to our Defender 110 300 Tdi Since the EGR has been removed, got me thinking about the exact timing of the FIP. WSM states as below. Injection timing............................................................... 1,54 mm lift at T.D.C. Injection timing with electronic EGR ............................ 1,40 mm lift at T.D.C. Does this mean that since the EGR has been removed, timing should now be adjusted to 1.54mm or not? Or is the pump different to non-EGR and should be left at 1.40mm Would be interested in your thoughts. Thanks, Simon... Quote Link to comment Share on other sites More sharing options...
Eightpot Posted June 7, 2023 Share Posted June 7, 2023 A1.54 is about optimum I think, though you can go a smidge further depending how much advance you want. Quote Link to comment Share on other sites More sharing options...
Phill B Posted June 7, 2023 Share Posted June 7, 2023 I'd say no. The 300 without the EGR had no ECU so everything was set mechanically. Yours does have an ecu so it should compensate to some degree. Basically, if it runs well with no smoke, don't play with the pump Quote Link to comment Share on other sites More sharing options...

Discovery 300tdi autos with EDC had an engine ecu which did change timing though. Quote Link to comment Share on other sites More sharing options...
simonpelly Posted June 7, 2023 Author Share Posted June 7, 2023 Thanks for the replies. The EGR and the ECU which was under the middle seat have all been removed. In fact, all the associated cabling has also been removed. Quote Link to comment Share on other sites More sharing options...
TSD Posted June 7, 2023 Share Posted June 7, 2023 I'm in the same situation, and have had the same debate with myself. My engine doesn't have EGR, but the pump was built for an engine with EGR. I have timed it to the EGR setting, but I'm tempted to advance it. It runs very smoothly and quietly, but it seems just a tad 'flat' - though it's been years since I had a standard 300tdi to compare it to. The car isn't on the road yet though, so any playing will wait until it's registered and on the road. (The 2.8TGV is a very similar engine mechanically, and without EGR from the factory, but the specified pump lift is 1.44mm. Not sure that adds anything, I just include it for interest.) The guy who rebuilt my pump said keep it at 1.4, but I don't think I agree. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted June 8, 2023 Share Posted June 8, 2023 Youll get more welly if you advance it to 1.54mm or slightly beyond that. You'll need a DTI that fits in the back of the pump. 1 Quote Link to comment Share on other sites More sharing options...
smallfry Posted June 8, 2023 Share Posted June 8, 2023 The more you advance it, the louder the clack clack clack becomes Quote Link to comment Share on other sites More sharing options...
TSD Posted June 8, 2023 Share Posted June 8, 2023 I have the DTI etc., but since I can't drive it on the road yet,I'm not inclined to tune it until then, so I know what state everything else is in Quote Link to comment Share on other sites More sharing options...
simonpelly Posted June 12, 2023 Author Share Posted June 12, 2023 I've decide to stay at 1.40mm as do not want too many changes at once. Quote Link to comment Share on other sites More sharing options...
