  • Diesel smart Power Module / chip Prado D4D

    Gidday, i am considering installing the above module into my 06 D4D Prado and i am wondering if any other PP have tried this module as apposed to the chip. A company based in Mackay QLD sell them and have a good write up on them especially the benefits compared to the chip. I have pasted some of their speel off ebay and would welcome some comment etc. Price is $990.00 delivered and they are virtually plug and play.

    Difference between a Chip and a Module

    Diesel Chip

    A diesel chip is basically a simple resistor which increases or decreases the amount of current that the ECU of the car sees from the fuel rail pressure switch. When the ECU sees that the current has changed, it will increase the diesel pressure to the injectors, therefore forcing more diesel into the engine creating more power. The downside to this is that the diesel is being injected at the same time as the standard injection timing is set at. This means that you will not gain any more fuel economy, but will gain power; this is known to be a fact throughout the industry. Because the Injection timing is not being changed as more fuel is being injected there is less time to burn, so fuel is being wasted.

    Diesel Module

    A diesel module is like an ECU, it controls each injector, it can change Injection Timing, Pulse, Width & Current. We can increase & decrease the amount of diesel going into the engine by controlling the injector properly as we inject more diesel into the engine, we can change the injection timing, giving the diesel more time to burn it, resulting in more power, we can also optimize the injection timing for factory fuelling resulting in better fuel economy.

    Diesel Chips have been around for a long time and are basically just a resistor, Diesel Modules are the future in common rail diesel engines, anyone considering a chip for their common rail engine would be MAD not to investigate the benefits of a module; Modules are far superior and more advanced than any chip on the market today.

    Hello guys, anyone out there care to comment. I am sure you have thought about the module as apposed to the chip anyway I might take a punt and try one in the next month after I have my d4d degunked which is happening at the moment.

    Cheers

      Same method the Steinbauer modules use. The only thing I don't like about this method is the fact that they don't add extra air when their adding extra fuel which means combustion tempretures are higher then normal.

        Thought Of Opinion Only

        Hi there frederick

        Thought id start the pace on your thread with some of my thoughts and feed back on points of opinion only!

        I do like the sound of the Module due to the fact that it has full control over the injector timing/fuel volume and keeping both the injectors and the fuel pressure pump at there factory designed specs

        (Higher fuel rail pressures promote more heat/wear and load on the injector tip and fuel press pump) so it seems more sense to extend the pulse on the fuel injector to let more fuel in (As appose to higher press) and take advantage of the ability to advance & retard these pulses to change injection timing etc.

        EG: Turn your garden hose on & squeeze the tip of the water hose very tight with your thumb and finger and take note on how quick they heat up with the pressure of the water being pushed through a restricted gap! This would be worse with higher pressures. (And that's no match for 6,200psi approx (42800Kpa) through 6 x pin holes).

        Further more!
        Australian owned company.

        German technology.

        10 year warranty.

        Just my penny's worth of an opinion.

        Cheers,

        Chris

        PS Do the performance chips compensate air mixture when bumping-up fuel rail press right across the fuel range??

          Let's not forgot that high fuel pressure is only governed by valves. The fuel pump is governed by engine revs. So chips that increase fuel pressure are just creating higher fuel pressures at lower rev ranges. So the pressures being put on injectors are no more then what is placed on a standardly tuned engine at higher revs.. Just trying to clear up some confusion about chips putting to much strain on injectors and fuel pumps when they actually don't. Plus fuel rails have a fuel limiter valve that opens to protect the engine if it gets to high allowing it to surge back to the tank. The injectors also have a leak back return line on each of them too.

            But what about the the shim to fool rail press?

            I personally wouldn't go messing with factory specs and increasing rail press as it would load the fuel press pump given that it goes High press pump/fuel common rail/injectors then fuel return dump valve to fuel tank!

            Extra press at injectors to get more fuel through the injectors puts extra load on the high press pump!

            EG: holding press high on the fuel rail holds extra press on the high press fuel pump irrespective to engine rpm!

              Suggest you look up the Chip It chip, it does a lot more than pump more fuel. Takes to long to explain but suffice to say you will see that what the module group is saying is simply untrue. In fact my recollection is it reads similar!!!! Take it or leave it.... and it seriously makes a huge difference!

                Hi Guys

                I didn't put up a opinion to start a loyalty fight!! Lol

                Fredric wanted an open feed back of opinion and no one replied so i got it started on my views of opinion only! Well!!! .... he now has something to read and he can judge for him self as i am not and will not pick any sides but i do think that provided that what is advertised to be true would be a better option to change injector pulse mapping as appose to fuel rail pressures right across the board!

                Don't forget the EGR scenario!

                We all know that when you go outside of factory specs that you also introduce a world of un-knowns and by sharing we can all learn off other peoples down falls with hope of not repeating!

                Our difference of opinion is not gospel but our difference of opinion we can all learn from and further educate our selves which is why we are supposed to share our un-biased opinions without starting to get offended by one-anthers thoughts

                Cheers

                  Gidday guys and thanks for your opinions and thoughts, yes another emotive topic for those stepping into an unknown area away from their comfort zones, anyway once back in Sydney next week after my week on the gold coast and after picking up the prado after having the inlet system degunked I wii test the increase in performance then decide if the module is warranted or not.
                  Priced at $990.00 with free delivery and 10 years warranty on the surface certainly appears to be a better deal than the chips,

                  Regards to all

                    Difference of opinion confusing and contradictive!

                    Hi Guys

                    I just wanted to give my points of view on a few points that don't sit right with me so i will break it down with "NO" intention of attack or slander and if i am wrong i will cop it sweet! And most importantly irrespective to who is write or wrong we can all learn and decide if we are prepared to go into the un-known with the consequences of our known knowledge.

                    Answer: The above quote is correct provided that the fuel rail pressures are not tampered with in the first place EG: (shim insert to fool rail pressures in high and low range) and "Yes" the fuel pump is governed by engine rpm.

                    Answer: if the shim is installed and voltage signals modified to the ECU changed to fool the rail press then BOTH high and low pressures ARE higher than on a standard tuned engine so the pressures on the injectors and pressure pump ARE higher! (Its just that the ECU hasn't worked it out due to being fooled).

                    So when you say Quote: Just trying to clear up some confusion about chips putting to much strain on injectors and fuel pumps when they actually don't.

                    Answer: I find your difference of opinion confusing and contradictive!

                    I also did take note on MidLifeCrisis 24-10-2011 09:29 PM opinion and i have read all threads and i can take it or leave it as i am only passing opinion with allot that needs to be desired as far as stress being imposed on the general mechanics of the stock standard engine. After all said and done i am not the one who is exposing my $60-70-80K car to "alpha testing" Explanation of alpha! http://www.webopedia.com/TERM/A/alpha_version.html

                    I would call "LIMP MODE" and "ENGINE MANAGEMENT LIGHT" a serious engine malfunction don't you think?

                    Also very similar scenario to the EGR blanking/restricting on the 1KD D4D!
                    Explained in detail here http://www.pradopoint.com/showthread...7-Blocking-EGR

                    EG: A test pilot wears a parachute and provided with a quick exit whilst "alpha" testing a plain! Once all safety standards are certified and the follow up of "Beta" tests deemed as safe then passengers are allowed to fly the plain without a parachute!

                    I suppose you could call the scan gauge/Exhaust Temp Probe/Limp mode and check engine light as your parachute! (I suppose if you don't mind pulling over to the side of the road erasing codes and messing with settings until you get a happy medium as appose to plug and play then that is your call and your time and money!

                    There has already been two 1KD D4D engines with cracked pistons due to injector malfunctions! (I am guessing hydrolic lock due to access fuel being pumped into the combustion cylinder due to malfunction of the injector as appose to cheap forged pistons i am sure) ....... I am guessing we will never know but I would lovvvvvvvvvve to know that if at one point had any sort of performance mechanism been fitted to these engines prior or maybe it was a genuine injector malfunction! One can only speculate! And speculate it is!

                    That is only just my difference opinion and point of view and not fact!

                    Here is a link that i found to help make all of the above make clearer sense for those who are not mechanically minded to the "TOYOTA Common Rail Diesel System" http://youtu.be/jWv5gYWvXaY

                    Hope it is all taken as an opinion only and not as a personal or directive attack as this whole talk is based on differences of opinion!

                    Cheers.
