Performance chips> Are they worth the money???

When are you going in for the comparison?

Bluefin 2.7 D4 is a hand held unit like the D3 2.7L one. When I asked they said that the only dealer they have over here is in NZ but he comers over to Oz regularly to do the maps for vehicles that need to be done with their machine on the vehicle.

I have the 2.7 D4. I've tried to look at the Bluefin/superchip web site, but the thing keeps crashing all the time, and it doesn't matter what computer or browser. Try to choose a car to get specs, and it just dies.

Might have to drop them an email I guess.

Not sure - we've agreed to do it, but no date between all parties yet.

Id like to get involved with any "testing" especially if it may generate some real empirical edivence , albeit that a rolling road dyno can only tell us the difference given proper double blind testing.Min problem with trying to draw any absolute figures is the dyno may not even be able to plot RPM;s against its Tractive effort calculations .On A DynoDynamics Dyno is a $10,000 extra to able to plot RPM. and without that we wont be able to calculate Torque ,This is why 99% of Rolling road dyno printouts only quote some rather useless HP or KW numbers .
With RPM , using the standard Formula of (Torque x RPM ) / 5252 = HP ,
Hence 444ftlbs or 600nm torque at 2000 RPM gives 169 HP and
Hence 244.8 HP or 180KW power at 4000 RPM gives 186 ft lbs 0r 251 nm
Makes for real interesting Torque curve especialy when overlaying all that boost.
Questions like what gear would you test it in, what ramp rate is the Dyno using ,
correction to STD air , Torque convertor flash and stall speeds , and the whether the operator can do a parasitics decell test to get a handle on Parasitics.
Also be interesting to check/observe the effect of each of the Terrain setting, which may dictate that all tests should be done in say 4th gear LOW range. It aint easy to get meaningful absolute figures from a rolling road Dyno , so only the differences when a parameter is changed/modified will be of any use.

I would assume that. whatever the increased figures on the dyno are after the chip / re-tvme, would reflect in the on road performance.

It will be interesting to see the longevity of the ZF 6HP's - with 700+NM in front of them! I saw in the ZF manuals that they have different torque convertors in the 6HP28 - depending on how much torque was input.

Done correctly, the extra so called strain on the driveline etc is only ever for a short period of time. When you are cruising on the speed limit, the extra torque etc is not in use.
Keep in mind that almost every vehicle engine is de-tuned. You will find that your Disco driveline, gearbox, diffs etc have been designed to take way more power & torque than what is being delivered to it now.
I have learnt that the most important issue with chips, is exhaust temperatures. Some chips can be adjusted by yourself with the turn of a screwdriver. If adjusted too high, the exhaust temperatures can run very high, causing overheating of engine, turbo etc.
I believe that the re-maps are the go.

Hi Craig,

Thanks for the feedback. Have you had a remap done and if so which one (presumably either Autologic or BAS) Was the additional Kw and torque as quoted?

Wayne

The BAS module has hit melboune now so she won't be long before I get this all working. I won't bother dyno before and after but I have a racelogic performanceBox at my disposal so I can probably compile some before and after 0-100km/h runs and some in gear runs before and after. On a " private " road under "controlled" conditions of course

Hi rova60,
Haven't had anything done to the D4 as yet.
Had a re-map done on the 2.7Lt D3 by Ritter Landrover Melbourne. Can't remember the figures, but was very happy with the added power, torque and economy.
On previous vehicles (Landcruisers) I have had the DP Chip fitted and always done test runs on the dyno to measure exhaust temperatures. I have found that with the add on chips, you have to sacrifice some KW to keep exhaust temperatures lower. A plus though is that the torque comes in at lower revs, which is what I was after anyway.
Cheers, Craig

Hi 400HPONGAS, would this be more correct?

244.8 HP @ 4000RPM = 320 LBS/FT = 434 NM
That is, if you transpose in your formulae, then
Torque( in lbs ft ) = HP x 5252/RPM.
Cheers, Don.
