Hilux 4x4 Forum

I have read a number of articles about the unichip that SAC and Dastek fit on the 3.0 D-4D engines with great success.

I had a Diesel Torque chip fitted on my previous Hilux (2010 Hilux 3.0 D-4D SC) with great results.
I did not put it on the Dyno to get the actuall increases in power and torque.

But what I can say is that it made a great difference in power. It went full speed on a straight. Cut out only on 192 GPS speed.
Even my fuel economy increased from around 10km/l to 10.8km/l. This will increase the more you get use to the excess power. In the beginning the feul consumption stayed the same but I got there a lot quicker.

The units is less expensive than the uni chip option and it is a plug and play unit. You plug it in and it works.

When I got my new Xtra Cab, I bought the new version of the diesel torque chip.
This is where my problems started.
It was smoking. I had to set the fine tuning to its max just to get the bakkie to stop smoking.
The multi function display was a mess. The on board computer calculated 11.5km/l but when filling up I got 9.9km/l.
Further more the chip cuts off the engine when gunning it. It cuts the engine off completely. I have to turn off the egnition and restart the motor again. Not the most fun I had on the highway.

I contacted the manufacturer and Craig is busy sending me a new unit.
To be honest and fair, Craig is a good guy, willing to help and taking up responsibility.

Is there anyone out there that can shed some light on the problem.
The answer I am left with is that the specific unit is faulty.

Regards

Ek het soortgelyke probleme met my Kaufner chip(nie dieselfde as jou chip nie) sny ook uit as jy hom brand, die suppliers het al 3 chips vir my gestuur als met dieselfde resultate, nou se hulle dis die valve op die commonrail wat te "pap" is, elke keer as die diesel druk te veel raak dan maak die valve oop om van die druk ontslae te raak om die enjin te beskerm. Dis wanneer die enjin ook uitsny. n Ander ou het weer gese dat dit nie die valve is wat fout is nie maar die chip self. Het maar die chip uitgehaal en ry met hom standaard.

Sounds like overfuel problem then the engine goes into "limp" mode to protect itself.

hi. i am new to the this forum, i have the same problem with disel torque chip, i would like to know how was it sorted ?

thanks olla

Having installed the small plug and play (Kaufner, Diesel Torque ect) and Unichips you cannot compare the products to Unichip. I cannot go into the details but the new range of common rail diesels are just to sensitive to simple signal interception because once you exceed a certain limit it will go into limp mode. I'm not saying that this could not happen with a Unichip if installed/tuned incorrectly but the results cannot be compared to a Unichip installed and tuned correctly.

Thanks.I really appreciate your response.so I guess yoi have an unichipplug

I have the same problem on my 2010 Prado ,
I have also played with the settings , I moved the position of the unit which worked fine for a while but today I get the call from my wife again that it started it crap again ........... Waiting for Craig for ideas .

The older gen unit in that Hilux works like a charm .....

will keep you informed

Welcome to the forum Alain.

it definately is the engine that protects itself from overfuelling.

Dylan also states correctly, it can happen with a Unichip, but you need to set the chip to some overfuel situation before it will send the engine into limp mode.

are you guys meaning that you are adjusting fuelling while driving?

not something which I would be comfortable changing without a dyno tune.
I'm seeing more and more units which are giving customers the ability to change fuelling by turning a knob.
Maybe it's just me, but I dont trust changing fuelling on the fly (maybe i just dont understand the concept fully)
or maybe its because my previous engine put a hole through the block, and sump, and other side of the block due to bad tuning... (not the hilux thankfully)

Thanks for the comments guys,

Craig from Diesel Torque called me back at about 9:30 and offered to exchange the unit , but after we chatted a bit I opted to send the unit back for a reflash.

Craig recons they have sent him some new stuff that seems to be sorting this problem out ... Thanks for the excellent service Diesel Torque

On the last comment of changing the fueling while moving .... not on this unit buddy ... But I have heard about that system .... but I recon if the preset maps are done properly it shouldn't damage anything

Thanks for the feedback guys

Ek het ook Diesel Torque probeer , Craig het ook my probeer help om die eenheid te herprogrammeer ens ens ens , ten einde laas het ek die chip uitgehaal want dit raak lewensgevaarlik , voertuig sny uit teen opdraand terwyl ek in vinnige baan die stadige verkeer ( lorries , karavane ens ) verbysteek !!!!!!!!!!!!! dit was chaos , 'n BAIE amperse ongeluk .

Ok Guys , got my unit back and no problems so far , car pulls well so lets see.

my reflash seemed to sort the problem out .......

same problem on my kaufner unit now
start, go, cut out, fustrate , vloek , switch off , start again
and this can happen quiet often lately

what i can figure out is the ECU on the new stuff is monitoring everything and the second something changes all hell breaks loose, Craige said the new software had alsorts of new codes inbedded into it to try and correct this , my one seems to be working and mom has done 1000km so far all town driving and no bollie !!!! will let you know if anything pops up.

I have a Kaufner for a d4d if anyone is interested.

Got the same problems with my unichip last week on my 2.7vvti but the problem in this instance was the chip was hanging from a paper clip behind the glove box and this thing while driving swung around there and i suppose lost contact at times. I fiddled with the plug and secured it in a propper place and havent had a problem since... Dont know if this might be of help to you guys but worth checking...

Goeie Dag.

Ek het gesien julle gesels rondom die Diesel Torque chips van Craig@DieselTorque. EK het die 2012 model Hilux en my chip sny ook uit met geen vaste patroon nie. Craig het hom al 3x ge-re-program, maar dit help niks. EK het 'n ander harnass ook al gekry. Steeds dieselfde. Sny net uit wanneer hy wil. "Koppige storie"!

Ek wonder of enige iemand hul probleme kon oplos met die DieselTorque produk sonder om die ding in jou boonste laai te gooi, want dit los die probleem op, maar ek hou van d ie ekstra Kw wat hy gee. Enige raad of advies>>>

Groete WJH.

Hi Alain.

Did you manage to solve your problem with the DieselTorque chip? I have the same problem on my 2012 Hilux>>> Any advise?

WJH

i fitted a freeflow from UTV(Dwayne) on the forum and that solved the cut out issues completely. Could set it 2 pins higher without any issues, traction control was had a good workout. Removed the chip when i took it in for a service 15000km ago and have not fitted it again as the difference with just the exhaust is ample. Would fit the chip again when i need to tow.

Middag Manne,

Ek weet die chips doen dit as hulle heeltemal oop gestel is.
Op watter nommer / setting is die chips gestel as 1 vir brandstof verbruik is en 10 vir krag.

Naandse. Kontak my ek sal probeer julle dieseltorque probleme uitsort.

Ek wil net graag weet op watse setting moet ek my Diesel Torque sit vir die beste fuel / power ratio op die Hilux 3.0 D4D.

Ek dink baie mense soek na dit maar mens kry nerens info op die internet nie.

Baie dankie!

Jacques

Hhs pm my asb

Weet enige iemand waar mens kan gaan kyk vir n Chip vir n billike prys?

Diesel torqe n yes of n no?

Dastek - Unichip.

Moenie dat enige iemand jou iets anders vertel nie.

Jou Unichip word in jou kar geinstalleer en vir JOU kar ingestel op 'n Dyno.

Al hierdie ander goed wat jy inplug dobbel jy met jou kar se enjin.

Om R1000 te spaar op 'n chip wat jou potensieel met R50k+ se enjin skade kan los is net nie die moeite werd nie.

Soos een ou vir my gese het, die chips lieg vir die ECU, en as hy lank genoeg aanhou lieg is jou engine gone.

Die chips goed verander inligting na die ECU toe, en soedoende oorskry jy limite wat die ECU gebruik, en die goed is ook nie altyd betroubaar nie.

Haai, ek het so 4maande terug unichip se Q4 in die bakkie gesit, ek het iewers n thread daaroor opgesit. Dis die unit wat jy aan die fueling kan stel dmv n map selector binne in die cab met 5 maps. Ek het met die verkoops man gepraat, en hom gevra of dit n goeie idee is om dit in die ry te verander, volgens hom is dit maar net veiliger om seker te maak die engine idle, en dit nie teen hoe revs te doen nie. Teoreties hoort dit geen probleem te veroorsaak nie, maar as die engine teen minder revs loop is die kanse dat iets die rekenaar boks gaan deurmekaar raak net soveel minder.
Ek het ook nog geen uitsny of limping mode issues met die chip gekry nie, en die Q4 haal BAIE uit die engine uit.
