My engine chipping experience so far

[MidLifeCrisis Out of control poster! Find all posts View Profile Close MidLifeCrisis]

Hi Robert,

Still researching & reading this thread, hence this post.

You say remove the chip before going to Toyota, that's fair enough - but what about the EGT? Surely that will get their interest up, as how many people would have an EGT with out a chip?

Has anybody else had a problem / issue from the dealer over this when in for a service?

Cheers
Lawrie

My rig is a 2009 Grande. I have the chip and EGT and remove the chip only for the fix price servicing and note it is still under new car warranty.

No issues at all.

Thanks fellas.

mmmm, but, and its a big "BUT"....if something goes wrong, such as a leaking injector seal or a blown head gasket, do you think questions could be asked? Would there be no issues then. It would all be fine until something went wrong I guess.

If it was all ok to run an engine chip, and if it didn't void warranty by having a chip, then why bother removing the chip just before taking it for a service?....is that honest?....should someone really hide the fact that they are using an engine chip from the dealer...its just a question worth asking.

the dealer will just point the bone at you REGARDLESS of whether they know it is a known fault or not. That's just what they do. Like the dealer saying "it will void warranty". Not all mind you, but most.

Remember, they get about $30.00 per hour for the labour and all the parts for free from the manufacturer if its a warranty claim. However, if they get you to believe it is your fault (WHATEVER YOU DID) then they get to charge you full tilt boogie (ie full retail price for labour ... circa $130.00 / hr) and you get to buy the parts off them for full retail too.

Its a question of economics brogers

You are not trying to be dishonest ... rather making sure they are not trying too pin the blame on you for something that is not your fault (or in this case, the chip's fault)

Good point... I can follow that, thanks

If I had a chip I would definately remove it prior to any service not just warranty. The less they know the better. There is a possibility that they would take a note of it having one and keep it on record. Then and if you had a warranty issue they will use that for an excuse and i reckon I could bet my balls there would be a digital photo of the fitted chip module to back up their claim. Its just easier to remove it then everything will be sweet either way in regards to a service or warranty work. Most should know what dealers are like, if they can get out of doing it under warranty and make you pay the $$$ as chip it has says then there way on front then if done under warranty. And in regards to honesty, if they gouge your paint work while working on your car, unless you notice it do you think they would tell you ?? ha ha, no friggin chance, what you dont see you dont know about, works both ways.........And by the way I worked for Toyota for 4 years, forget how many vehicles we pinstripped to cover scratches)...........(salesman)---Sorry sir we pinstripped the wrong car, we can remove it if you dont like it bu there will definately be no charge for it, you got $300 worth of stripping for nothing, Customer--- na leave it looks quit smart, I like it....Salesman thinking--- you beauty done deal dont worry about the rust in years to come.......honest Cheers Steve

Remember that from a legal perspective smoke that looks like its from a gun doesn't mean you fired the gun, e.g. the whole set up, EGT, and waterproof box doesn't prove you use the chip--for legal culpability. Its a bit like those SUV owners who bravely go solo into backwoods car parks and periodically mount a curb at traffic lights?!

good point.

So guys,
Having read several pages back - component issues were identified as the cause of problems with regards to check engine light as well as starting issues - is it safe to 100% say there are now no problems associated with running the chip it chip on standard tune with the 150 series.

I am currently in Perth from Newcastle nsw with my Prado and remain very interested to purchase a chip. I have been waiting/reading this thread since mid last year. Chip it - can you confirm the malfunctioning circuit components have eliminated all check engine lights as well as all starting issues.
Regards

Will know for certain in a bit under 2 weeks, when I get an EGT & Chip in.

I installed my Chip-It recently and remain on the factory supplied tune. Also have a SB chip, plus Airtec snorkel and 3" exhaust.
Currently at Coral Bay, enroute from Broome to Perth. The camper I'm towing probably comes in at over 1200kg with current load.
I have experienced the non-start on three occasions. First time, started second crank. Second time, started third crank. Third time, started fourth crank. That's not good, but the extra power when towing in windy conditions is great.
Double chipped, hopefully not double trouble!
BTW, not towing, the damn thing accelerates like, well, something that accelerates very quickly indeed.
Towing fuel consumption seems to be a tad worse if anything at all. More power, more fuel stands to reason.

I don't think it's a good idea to install a performance module on any of the 1KD-FTVs at this point in time.
The situation at present with the internal design of the injector system really doesn't allow for this. More power = more heat, especially in that middle band of the head. There is already a problem with heat transfer causing the seals and the injectors to fail. Any increase in block and head temperatures just will make matters worse, speeding up the failure process of these two components sooner, just my opinion.
This is why on the most recent update or reflash TMC wand back the fuel values especially in the idle and cold start parameters of the software in the ECM, to try and fix the problem.
Ok, Denso has gone a long way to redesigning the new G3 injectors, with a new solenoid, better head design and materials, but the problem still remains, and that is heat transfer because of the internal design of this set up.
Having the EGT probe there on the dump pipe will only tell some of the story and will not give the full picture when it comes to the area in question, that being the middle of the head where the mounting sections for the injectors lie. This is why with the new seal design TMC have coated the seals to try and reflect some of that heat from the injector housings.
Even if your module is increasing the air flow by controlling the vane turbine better, this will also increase the heat of the block and the head.
It's a no win situation with how this fuel system and head are designed, at least from your point of view, and what you are hoping your module will achieve. I am not saying that it won't achieve what you have designed it to do, and that is to provide more power, I am sure that it does, but it will also take some of the longevity out of two components that are already pretty stressed out as it is.
Your module and at least one other brand, are great on any diesel engine that doesn't have this internal design for the fuel system, eg. 1KZs, 1HDs, 1HZs, Puma i4 and i5s, for that matter, any CRD diesel engine that doesn't have the injectors mounted underneath the rocker cover, etc, etc..... but with the 1KDs I can't see it being a good idea.
Just my opinion, the Roo.

Thats interesting mate where do you get your information from if you don't mind me asking?

[Guest Close Guest]

Roo please stay on topic.. This is not the thread for discussion of anything but engine chipping experience.. Plenty of other threads to post your info in that are better suited.

I have also been following this discussion for a long time with the aim of chipping once all the issues are cleared.

Some interesting info Roo, thanks for the link. Will a new thread be started on this?

Couldn't see much in that suggesting temp related issues, the changes to the injector learning control seem to be aimed at achieving euro4 standards. The seal changes sound like they are related to pressure issues. I'll save future comments for a new thread.

for all intents and purposes, as far as we know the problem has been licked. (NB... I did believe this was true last time too )

Seriously though, the new revision (for 150 Series Prado and 70 Series L/C only mind you) seems to have been the right move.

Mind you we have sold approx 29x 150 Series Prado Chips in last 2 weeks and so I am talking from some vantage point

Cheers
