Td5 Black smoke

[Epic_Dragon]

Howdy fello landrovians, i had my td5 d2 tuned a couple of weeks ago, but now under semi hard acceleration it blows a nice cloud of black smoke. has my vehicle been tuned/chipped incorrectly or are my injectors likely to be needing replacing? I know black smoke is caused by over fueling. Car is running amazing otherwise. It is due for a service too.
Also with the chip/ecu upgrade tune thing is it safe to disconnect thr battery at all?

Intercooler hoses on the way out? The original ones delaminate, over time. Check that first , especially the one from the turbo, to the steel pipe. Bob

Hi,
Do you know what sort of chip you had fitted? If you had a piggy back type tuning chip it basically fools the ECU into upping the fuel rate across the whole Rev range thus causing black smoke on acceleration and at other times.

If you had an ECU remap you will still get some black smoke under certain conditions but in my experience it is much less. Again, if it's a remap say from BAS you may be able to fine tune it. Contact the workshop and ask what your options are.

Cheers

should be no problem.

As said, some fine tuning is possible as long as it's NNN ECU and it's remapped via OBD port, if it's MSB ECU only other chip with different map would make a difference, mine is with MSB ECU and had that black smoke after the tuning, what i found was an old unworking depression control valve and the adjusters on the rocker shaft were too tight(i think they were so since i've bought it)... new valve and the adjustments fixed as in the book and almost no smoke now... only what's normal in these cases e.g. if i floor it like mad uphill with the trailer attached.

The first remap on my D2a resulted in copious amounts of black smoke under even light throttle. All OK after an adjustment to the map.

HI.
Reading between the lines, and threads, you have probably got the ecu change-over from the well known Landrover wrecker south of Adelaide? His tune is notoriously smoky/fuelly at certain revs. So much so that exhaust-gas temperatures can get alarmingly (damagingly) high if driven hard and you are unaware of the extra head generated. It wont show on the temperature guage. Towing in hilly country can cause the high egt that trashes manifolds, turbos, ask me how I know...
Once tuned, I found it hard not to use the extra power, and TRS may not have warned you about the heat issue. Its why a lot of people on this forum, myself included have fitted egt guages. I dont think TRS can fine tune their chip, its a one-size-fits-all type of thing.

Td5 injectors seem pretty reliable if filter is kept serviced (my original injectors now have 380k km on them). Intercooler hose delamination is more common but will usually be accompanied by reduced power at the same time as the heavy smoke, which clears if you throttle back. The extra heat, I suspect, also ages the oil faster, shortening its service life. The chip is hard-wired in the ecu box, a flat or removed battery will not interfere with it.

Best regards, Jason (eastern Adelaide)

TRS, I asked them to trick my computer but they said it was already done, that was good, but how can I find out what where was it done and by whom?

Mine also has gas fitted, not much use if the engine is already fueled to the max.

I note that when running on diesel only, I get better economy than when using gas as well, however the overall cost is slightly less on gas. I now, (Thanks Be Utey), know that gas can only use any oxygen not used by the diesel, with bulk diesel being injected gas is virtually useless, I'll try get the gas flow down so low that it will help, wish me luck.

What is an egt guage? It was there yes. What should i do if its the chip and it's going to harm my engine? It's not heaps of smoke but rather it have none. The engine is running more efficient and seems to not work hard at all compared to before lol.

What is an egt guage?

egt is exhaust gas temperature i believe.

[d2dave]

egt is exhaust gas temperature i believe.

Correct.

Epic dragon. If your engine is chipped or ECU remapped the reason for more performance is more fuel. If over fuelled this will cause black smoke.

Now this will also cause high EGT's. Running high EGT will do damage possibly melting pistons. It is easy to avoid. Get an EGT gauge with an alarm. Preset the alarm at a temp a bit below max safe level.

If the alarm goes off it is just a matter of lifting the loud pedal a bit and your EGT will instantly lower, before any damage is done.

Find an EGT gauge and get it fitted. Running a tune on a Td5 with no EGT gauge, particularly in applications like towing which I'd hazard a guess that you do a bit of, can cause significant damage as Dave says above.

If you're running the tune previously mentioned, then yes, they like to run hot, and they will smoke.

Get that EGT gauge on there stat! :) And disconnecting the battery will be fine.
Also look into finding a D2a intercooler to help off-set the increase in EGTs you'll see from the ECU.

Thanks :) yeah i do plan on getting a d2a intercooler. I got it tuned as was so sluggish to go wasnt heaps safe pulling out on the country roads i live with blind corners etc. I do tow, also like to go off road. Never push my car too hard though but im not slow either. Are there other tunes that do not smoke? Small price to pay i suppose when it does go a lot better. Much safer have to find egt Guage and d2a intercooler.

[Epic_Dragon]

Whats safe temp it should have egt guage alarm set at?

[Graeme]

Invest in a proper large intercooler. With just a large I/C and no remap summer heat didn't cause mine's performance to be curtailed nor did the heat affect it with the remap. Never had any exhaust manifold dramas either.

Were is a guide to EGT's.
