My engine chipping experience so far

[Chip It Senior Member Find all posts View Profile Close Chip It]

Hi Eugene

we can program it to either LOWER the tune or dump the performance tune completely.

The reason it comes out of the factory with the second option is that we want the engine to get back to "normal" temp range as soon as possible and we dont know if the temps will lower if we just reduce tune by ... say 10% or 15%.

We can switch between maps. Again ... whatever is programmed to the second map. But remember the reason we have the EGT controller is so that you have HIGHEST power that YOU like for as long as the temps are "reasonable"

This is what I have on my car too.

Just makes sense this way. ie Give me the max setting but dump it if it gets too hot. A dual map switch is available but the EGT controller would not be using a STILL lower tune. It has only two maps it can switch between and if u have the switch on the lower setting you have switch ed to the map that the EGT monitor would be switch to, from the higher map (hope that is clear)

Yes we can use other means to detune.

Yes to intercooler sprayers and the like. The relays can be added to board at time of order for no extra cost (to you). The ON point can be via load or boost as these are what we are "sensing". The EGT monitor would not be able to switch it on as we set the "alarm" ON point too high for effective I/C spray cooling. On HIGH LOAD would be the best as high load would be the time when air is the hottest. You could set the on trigger to trigger a timed relay so that the count of say 1 minute would keep the spray working for that time or if the load was continuous the relay would just stay on. These relays are available from Jaycar.

Hi Robert,

I would like to ask a few questions if I can so I can get a better understanding of the capabilities of the “chips”

With your EGT temp set-up fitted, does this “switch off” the “Chip” until a safe EGT is reached, or does it lower the sate of tune to a safer level until a lower EGT is reached? Is this a separate tune, or does it remove a % of fuel and/or boost from the original tune, can this amount be varied?

If it lowers the sate of tune, does this mean your “chip” has the ability to run dual maps and switch between on the fly?

If it can run dual maps and switch between on the fly, can I use other means of switching? Say eng temp, ambient or intake temp? I know that EGT (pre turbo) is the best way to get fast response to high engine load situations, but I was just wondering.

Can the EGT unit, or indeed the “chip” be used to control other things like intercooler sprays, or water injection?

Could I set it up so the “chip” will tell the Auxiliary out (say intercooler sprays) to come on once Boost reaches a preset level and EGT are above a certain level, or can it only switch with input from one parameter? I would like to set-up sprays so if towing, long hill, temp coming up, before the EGT probe switches the chip, it can trigger the intercooler sprays, I don’t see the need to have sprays running the whole time your on Boost, only under certain points.

I know I can set up the above with a pressure switch running through an EGT unit, but if the “chip” can do it, why not use it.

If the “chip” has the ability to store two tunes and switch between on the fly, can I fit a manual switch to “detune” the “chip” if I know I am going to be in a situation that doesn’t need all the grunt, or load a safe or valet tune for when my soon to be 17 year old gets his “P’s” and want to take the Prado or Navara for a flog session?

Sorry for so many questions, but I think the more we know about these units, the better it is for all, I have had a fair bit of time tuning and modifying XR6 turbo falcons using the Xede unit from Chiptorque and later on the SCT “flashtuner”, the Xede unit had dual mapping with switch on the fly, was very handy in a Ute with over 350rwkw and well over 1000nm of torque to be able to detune for rain, wife, towing etc.

Thanks in advance.

Yes the fuelling is normal Toyota spec and so is the boost.

Boost is only increased when fuel is added (ie load is high). At cruise load is low so your turbo is that ticking over and producing little boost (circa 4-6 psi)

Thank you very much for your response Robert This is one os the reason I went with Chip-It, I don't see any other chip manufacturers on here supporting there customers like you do.

I have one further question if you don't mind answering mate?

When you say what is quoted below, does this mean that when I'm using cruise control at say 100 kays the HP pump isn't trying to cram more fuel in the rail and it's operating at a normal pressure? If so that is pretty impressive. But is the turbo running factory boost too?

Thanks for that,

I understand what you were saying about the EGT protection only working from top tune to lower tune, not on all, I had similar set up in falcon, only the other way, when the trans selector ( 6 speed auto) was in normal, you got the "low tune" of only 320rwkw, when you flicked the selector into sport mode, or manual shift mode, you got the full tune, worked well.

Thanks again, I will be in touch as soon as I have decided on what exhaust.

the flick back to lower tune can actually work on ANY tune ie from any tune to any tune, but we send the units out with tunes that go from ANY tune you choose to zero chipping. however the second map can be any that we choose.

This is what I have requested on MUMSRIG. Just awaiting the programming to be upgraded. Hopefully I will be taking it in to Balcatta tomorrow or during the week to have the upgrade installed. The switch is ready to go, it's just that the 1KZ didn't have the option available as far as I understand?

I can't believe the power difference that we have noticed though... Bloody unreal, she pulls like a............... well, you know what now!! ;P

Hi All,

This is in no way a dig at Chip-It, the chip is fantastic and very glad I got one.

I went to remove my chip last night before getting my 12 month service done next week but found a slight issue caused by the company that installed the chip.

The Common Rail plug sensor had not been restrained after it was installed and has since been in contact with the EGR cooler pipe. What this has done is melt the plastic connections making them impossible to undo. I then cable tied the Common Rail plug sensor connection to the fuel pipes lower down on the engine so it can’t come into contact with anything hot while I work out how I am going to fix it and delay my service at Toyota.


After I found the connection and got to a place I could view it. Yes there were a few colourful words said when I got a look at it.


Now restrained as it should be.

I spoke to Chip-It today about how I can fix the issue and their customer service was excellent. Peter could not do enough to help and advise me as this may not be an uncommon issue when not following instructions. Once I have the new connections, either I will replace them myself or have my local auto electrician do it for me.

I will not be contacting the numb nut that did the installation as there is no way they will ever touch my Prado again.

If you have a Chip-It installed or know someone on here that has one, please have them check this cable and hopefully we can help others can avoid having this issue.

Great post Dave

Let us know if we can help with souring the plug as Toyota will want to replace the whole loom. I will have to destroy a harness (or give you the complete one) but then you will have both sides of the plug and can just back out the terminals to plug into ours (or spice in whole new connection if you cannot get the terminals off)

The harness costs $249 ... I can do it for $200 neat plus freight if you need it

BTW. The installer said he is in contact with you about this. I trust that is correct.

Cheers

Hi there Chip it, correct me if Im wrong but the instalation was done by some one that sells your product to the public ?? (not you yourself, who ever it was) Not sure if I read your reply wrong or not but you will do the harness for $200 as you dont think Toyota will have just the connection ?? Shouldnt the employee from the company that fitted it be getting a kick in the rear end from his boss from not tying up the wiring loom as per instructions and the part be supplied to DGW free of charge by the other company to fix the problem ?? (no cost to yourself that way or DGW) If it was my $70,000 prado and some one else stuffed up a job they were paid good money to do I sure as shit would'nt be paying a further $200 for it to be fixed. I know your trying to help but shouldnt the boss of the joint that fitted it be offering the loom to DGW not yourself ?? Cheers .........

Hi Chip-It,

Yes the installer has contacted me today. Still deciding on exactly what to do.

Steve,
There are reasons why I dont want to go back to the installer. 1, the logistics of dropping the car off and getting back there before 5pm on work days is not easy. 2, I was not very happy with the work that was done before I found this, so I am very hesitant to use them again. So from that I hve to work out what I am going to do.

Either way, I have to do something.

Thanks
Dave

Yeah mate I feel for you, I have been in the same situation with 2 of my previous prados and now I have the 120 Im not sure who Im going to trust to fit my OME when I have the $$ to get it done. I myself wouldnt let them touch my vehicle again either so totally agree with you there. I know its ony some thing small BUT this could have led to a more serious situation, like either the connection melting write through and stopping you dead in your tracks in the outback god knows where, or worse caused a fire and watch it go up in flames and hopefully no one get injured in the process because some one who didnt do THEIR job properly or even notice that ""hey thats going to hit that maybe I should tie it up out the way"" or read the intructions and do what they say. There is no way I would be paying a further $200 for some one elses stuff up. It's good to see quick follow up from chipit above and obviously chipit has rung up who ever supplied and fitted it and said hey you guys stuffed up fix it !! give the fitter a warning to do his job properly. Has any one tried ringing some wrecking yards and see if there are any D4D's 150's damaged (chances are probably not) and if so should have the same loom, would cut the connection off and get it fitted, or as chipit has said the company that fitted it (not chipit) supply a new harness, you take it to your choice of sparky get the connection changed over (wont be as easy as just pull each wire out as it will have been waterproofed) and they pay for it, What maybe $300 including new harness, will teach the bloke that fitted it a lesson. Without seeing the loom and following it, it would be hard to determine wether it would be easier to change the hole loom or just the connection, maybe if you get a chance to try and follow the loom back around and see where the other end of it hooks up, maybe only a short loom and still finish in the engine bay some where, if it goes back to the computer then maybe a lot bigger job, but still at the end of the day they stuffed it. I would also just like to say in no way am I bagging chipit, or the use of it or anything like that, thats for sure, its obviously a great product BUT as I have had a lot to do with sales it would be in the best interest for this company that is selling chipits product to fix your vehicle at your choice of sparky as they would more then likely know it will take one person to read this thread then post it on another forum and change the whole story which could end up giving the company a bad name. Good luck with your decision and hope you get it sorted real quick. The best thing to come out of this is that you were due for a service and you found it before and serious damage was done...........Cheers Steve

You may be able to source the plug assembly from toyota, the pins will be able
to be removed using the correct proceedure and inserted into the new shell.

If you know a electronics repairer, he should have a hot air gun that is used
to remove surface mount components from printed circuit boards. These guns
are very small hot air guns that provide a highly controlled stream of hot air to a
small area. Using one of these you should be able to re-melt the plug in the fused
area and pull them apart. Then assuming you can get the shell transfer the wiring accross.

Unfortunatley Toyota may only sell the form, in which case try a wrecker or someone on EBAY
selling parts from a wreck, they might cut the pulg off for you.

If you get desperate Narva stock a range of multi pin connectors but they won't be identical
to the Toyota one.

Correct. An independent workshop in Sydney did the fit up and yes they were advised. Basically I called and advised that the mechanic had failed to tie down the harness and that on this vehicle (type) you MUST tie down the Common Rail harness as the (bloody hot) EGT pipe is just above.

The $200 harness HAS THE BIT he needs ... it is not the whole harness that is needed but only the plug. Unfortunately the only way we have the plug (to help out) is to provide the whole harness and cost out as same.

Also correct that I would have the installers pay for their cock up.

Dear Mr Chip It

I have been following this thread with interest and have been thinking about puting a chip on my 150 series and would prefer to support a local brand where possible.

Are you able to provide an overview on the status of the 150 series D4D Prado chips, with a focus on the issues that have been raised in this thread and what you have done to fix them?

Can you now guarantee that anyone that puts a Chip It chip in their Prado and will not experience the issues raised on this forum, i.e. fault codes, power cut outs, excessive smoking etc etc (I am aware that you effectively provide this guarantee in your terms of trade, but i am more asking whether the issues have been fixed).

Thanks

[Chip It Senior Member Find all posts View Profile Close Chip It]

Yes Lortap

all issues fixed

... and you will be a very happy camper

Hope this helps

Cheers

After several long discussions with company that fitted the chip, they will be fixing the plugs next Tuesday. AS I have said, this is not a reflection on the product itself, just a small but possible costly error when the harness was fitted.

The reason for raising it on here, was to alert people who have any chip fitted to a D4D, to check that this part of the harness is well out of the way of the hot bits just above. From memory, most of the chips use this connection, so I would hate for someone to be totally disabled by the lack of a 5c cable tie.
