  • Could my Dtronic be playing up

    Hey

    1kzte with 2.75" beaudesert exhaust, dtronic in good nick.

    Just recently it began running rough at idle and not pulling like it should. Figured at 220k its time for some new injectors and replace the glow plugs. Fuel filter is sweet.

    But, tonight I thought I might pull the dtronic and take that out of the equation.

    It runs fine without the chip.

    Could the dtronic be faulty and if so how would you check it?
    Does safari still support them? Couldnt see anything on their website but on iphone so a bit hard to read.

    Thoughts?
    Advice?

    Don't think Safari support them anymore, the last of them would be well out of warranty now I would think (was it 5yrs)
    Maybe worth a call to them though, you might get lucky.

    I don't think mines quite right either, still goes very well but occasionally I get surging under acceleration in low speed/high gear. Never happens when I unplug the unit although it's so intermittent I'm not 100% sure.

        An update. Turns out the MAF needed cleaning. Back together and hauling butt. Sweet.

          Hey Guys, Can anyone help me with install instructions for my 07 D4d for Dtronic. I took the glove box out and saw a unit that has 4 plugs in it, does it plug in there? Also the brown wire that is hanging out of the system does that need to be put somewhere? Sorry about the dumb questions but I am a complete novice. Getting the 3 inch Exhaust with ETG fitted soon and then want to plug this thing in but??

            Plugs should match up to back of ECD, should have been supplied with a "Y" harness and I THINK from memory that the brown goes to earth, does it have a ring terminal on it?

                    There will be a self tapper somewhere near the glovebox. Still going strong, didn't do the exhaust, wouldn't go 3" as I suspect it would move the tq/hp curves where I would not use them. I tow the 2t van at about 23-2400 rpm so I need the go around there. Might try removing the muffler one day and replace with a straight through. Standard pipe is 2.25" which is fine but the crushed bends don't help. If they had done mandrel bends at manufacture it would be fine.

                        If you want the best reading from EGT drill and tap the manifold UPSTREAM of the turbo. Turbine INLET temp is the one you want to see because that is the temp that closest to what the exhaust valves are seeing. If you tap the dump pipe you have to guess the temp drop across the turbo, nobody can give you an exact number but it is supposedly about 100c by popular best guess. A more free flowing exhaust should keep EGTs down, your turbo should spool up faster, but you may lose go at lower revs with more hp/tq higher up. Not what I look for in a diesel, if you want stupid amounts of power get a 4l V6 and an oil refinery.

                          Thanks for the tips t303, I am now considering leaving the standard exhaust and installing the EGT as you recommend above to monitor the temps. With careful driving and throttle management it should be manageable to avoid any issues. Just out of interest what would the lows and highs be for ETG readings upstream of the Turbo for a Prado? Would EGR blanking affect this?

                            As the sign they use on Q.I. says: "Nobody Knows!"
                            Only the engine designer might be able to tell you the design limits for EGT, but seeing as it's an alloy head (so I recommend coolant temps below 100c as well) I would err on the side of caution. Personally I have the EGT alarm at 720c and change down or back off when it sounds. I have seen a 790c peak, and it is a time thing as well, ie pistons etc held at temp x for time y will at some point suffer terminal stress or meltdown. It is intriguing to see what pushes up the EGTs, obviously flat foot heading for redline will do it, but due to the turbo spooling up as the loud pedal goes down it will get up surprisingly quickly on a slight uphill in 5th, particularly with the cruise control on. I can't see how a blanking plate would affect it much, it only stops blowby gases from being fed back into the intake and in a decent engine there shouldn't be that much.
