200 Diesel in Florida!

[Dougal]

Nope, not a vendor, agent, relative or anyone who makes a profit from this stuff. I researched this considerably before getting one. Popular ones in Au are Dtronic, unichip, DP chip, Steinbauher ( or something). I have experienced about 15% extra power and ever so slight decrease in fuel consumption. Go to Australian 4WD Monthly Online Forums - Search Results which is the 4wd monthly forum search on th subject.


You will see hunderds of user opinions for yourself.

Not sure what BSFC is but here is the dyno results from one vendor.

Dyno Graphs - Results of Power and Torque Increases with the DPChip fitted to various vehicles


"The 2.2L diesel in the Avensis puts out 400Nm, since the V8 is similar to two of these combined the potential output could be 800Nm. Toyota will have very good reasons for detuning this engine, uprating it without understanding why could prove to be very expensive"
Maybe but if it really is 2 of these put together isn't 800nm which is more than enough?

It also isnt a simple matter of more fuel = more power, 3rd generation CRD's less LESS fuel to develop MORE HP by injecting several smaller amounts of fuel as it burns.

In the UK the 2.2l diesel in the Avensis is available as a 140hp (310nm) or 177hp version (400nm) with almost exactly the same economy. The only main difernece is that the 140hp version is marlketed as low emission( and therefore gets tax breaks). How does your explaination work there? I think this exactly proves the point.

BSFC = Brake Specific Fuel Consumption. It's a measure of how many grams of fuel are required to produce each kilowatt of crank power. Lower numbers mean higher efficiency, i.e. less fuel for the same power.
You may not be aware, but modern common rail engines do not have significantly higher peak efficiency than many of the old mechanical injected diesels. My 1985 turbo diesel has a best BSFC of 209 g/kwh. BMW's 535D engine only makes 205 g/kwh.

The only way a chip could provide better fuel economy is if it improves BSFC or via the well known placebo effect.
I'm not going to believe that an aftermarket tuner can get better efficiency from an engine than toyota can, so that just leaves the well established placebo effect.

Power and torque increases are granted, I've seen many such dyno plots and don't have a problem with them.

The pre, main and post injection events of commonrail engines were developed by the engine manufacturers, not aftermarket tuners. The primary goals of that are noise and emission reduction. Again this is not something that any aftermarket tuners have improved upon.

Toyota UK do show a MPG and hence CO2 emission difference between the 177hp and 140hp 2.2L avensis engines. The higher rated engine uses more fuel on the same test standard.

Someone needs to go nab this and take it to a remote location in Montana and never register it!

Go for it mule!! there's plenty of room for it behind your grandpas shop!!

I'm no diesel scientist, but I can tell you my chipped Cummins, which DID modify the boost and fuel maps got significantly better fuel milegage, and it's a fairly simple thing to understand, by leaning out the mixture you are making the same or more hp with less fuel or more air...

Now to be fair, i seriously doubt my truck was with in emissions tolerances... but i can tell you that my wallet felt the difference signifncantly, with a 36G main tank and a 100G aux tank, I was able to run approximately 2100 miles prior to the banks mods, after the banks mods I was able to run close to 2900 miles on the same amount of fuel.. you do the math, i gained an easy average of 6mpg, in fact it would probably be even more except that I started driving it faster as well, if i had kept the same 65-70mph and hadn't switched to 35" tires I bet I would have gained 8mpg.

Diesels always run lean, if you run them leaner (i.e. less fuel) then you get less power, this is exactly how your engines power is controlled.

The % increase in fuel economy you're claiming is unheard of. But your final figure (2900miles, 136 gallons) comes out at 9km/l which is believable and makes me wonder if there was something wrong with it before the mods.

Did you correct your odometer for the bigger tyres?

I friend of mine who owns a Toyota Dealership in Venezuela just gived to me a brochure intended for the all the sales reps for south america and the caribbean in spanish, which list all the available models and options for this market and for example the V-8 4.5 lt 1VD-FTV diesel came in two flavors: one with 162 KW @ 3600 RPM & 430 NM @ 1200 - 3600 RPM and one with 173 @ 3200 RPM & a whopping 615 NM @ 1800 to 2200 RPM.

Common Rail, Multi Valve, Twin Turbo intercooled and EFI.

The first flavor came with a 5 speed manual transmision and the high powered model came with the ECT-i secuential 6 speed auto transmission.

Manual transmission models are the VDJ200L-GMMNZ , VDJ200L-GNMZ, VDJ200L-GPMNZ and the VDJ200L-GNTNZ and VDJ200L-GNTEZ are the 6 speed auto transmission been the the last one the most expensive available with KDSS and more !!!!

Just go to any dealer for example in Panama and place your order, of course whatever goes from there to get it to the states is up to you .

You can always buy a trailer and town on road your unlegal 200 series until you arrive to the off-road section and drive away with all that blasting torque

Unfortunately here only the 5.7 gas powered model will be sold and doesn't came with KDSS because of stiff duty taxes. Also AFIK only one unit per month per dealer will be imported and the waiting list is quite looong.
