My engine chipping experience so far

[pinko351 Member Find all posts View Profile Close pinko351]

In my experience my EGT's have been lowered by the chip while adding more power. To back this up, I recently had the Prado serviced and removed the chip.
I then had to tow my horse float carrying 2 horses before I had time to refit the chip. Straight away the difference was incredible, I was constantly having to back off due to the EGT raising to and above 600c.
Alternatively with the chip fitted I'm able to (with in reason) maintain legal speed limits while keeping the EGT around 500-550c.
While switching back to the standard factory program may be required for the higher settings, for my mind at setting 5 (in my case) my engine is safer while running on the chip.

Every chip on the market can increase engine temps ... EVERY ONE! We just choose to give customers peace of mind with ours and have this option so that if (say driving up a long steep hill towing a heavy van or boat etc) the engine were getting up to a EGT level that is higher than factory, the Chip would de-tune itself.

Considering that other chip sellers (I say "seller" because none of them actually manufacture [as we do]) do not have an EGT controller we have nothing but good will from our clients that thank us for at least having a safety device like this as an option in the first place.

Remember that what kills mechanical parts such as engine, gearboxes, diffs is heat and revs. Argument can thus be made that if the engine is producing more torque at MUCH LOWER engine revs, there is no need to wring its neck to get it to go so you may actually be saving your engine!!!

All engine safety features are retained. We do not short circuit these at all. Don't know why you thought we did. I mentioned that others are not intercepting the secondary signal but this is not a safety feature ... it is their mistake ... not their advantage!

Quote: We do not short circuit these at all. Don't know why you thought we did

Answer: I did not at any point insinuate that you short these circuits?

My Quote: what is the sustainability on long term engine life span now that you have managed to over-ride the engine protection perimeters put in place by Toyota and the other chips leave in play?

Question: When you intercept the secondary variables in what way are you modifying those signals in-order to stop the CEL which is usually triggered when engine sensors are running outside of there original mapped perimeters.

I am not asking for trade secretes but more on how the engine can protect its self if normal data feed back is being modified when intercepted and normally the engine management can protect its self based on data feed back that you are modifying.

Question: If "all engine safety features are retained" what are you doing to the secondary fuel rail feed back data to stop up-setting the ECU (normally followed by a CEL)... Is this so the ECU does not know true fuel rail pressures (I call it a safety feature) and can no longer drop fuel line pressures when out side of its original mapped perimeters.

I do not want to come across as trying to undermine your credibility as good competition is "always welcome" and strongly encouraged as it forces all other competitors on there toes and this makes better/cheaper products for us the consumer but what you are claiming does not appear to be adding-up and i am not sure what i am missing as far as the engine being able to protect its self when you are intercepting and modifying the secondary signals.

Cheers

you misunderstand what the secondary signal does and do I believe I read correctly that you are saying our Chip will, in-time, cause issues.

You wrote "now that you have managed to over-ride the engine protection perimeters put in place by Toyota ..."

In this sentence you are saying we over-ride the engine protection AND THUS put the engine at risk.

Correct me if I am wrong or misread your stance / opinion.

But to make this clear ... no we don't over-ride any safeties or put the engine at risk by modifying both signals.

The secondary signal is a voltage correlation between a and b signals. By not having a tune box that does both signals other companies mismanage the signals and the factory ECU sees this offset and throws up a code. Basic speak ... they don't do it correctly.

Hope this clarifies. If I am misunderstanding maybe someone can explain to me.

Hello chipit

Quote from chipit: you misunderstand what the secondary signal does

Question to chipit: Yes i have clearly misunderstood what the secondary signal does as i am having problems with your interpretations so could you please explain what it is that you are actually doing with that return signal before it is forwarded to the ECU and i will keep in mind that the signal that is being forwarded is in "correlation" with the primary signal... So what has happened to that secondary signal (If anything) before being forwarded?...

Quote from chipit: and do I believe I read correctly that you are saying our Chip will, in-time, cause issues

Question to chipit: You will have to point out exactly where "i" said "Quote from chipit": that you are saying our Chip will, in-time, cause issues un-quote.

Quote from skywalkerrun: "what is the sustainability on long term engine life span now that you have managed to over-ride the engine protection perimeters put in place by Toyota and the other chips leave in play"

Answer from skywalkerrun: I believe that "if" you have intercepted and manipulated both the primary and return signals then wouldn't it have compromised a safety perimeter that was put in place by Toyota due to the signals being manipulated from there former state?.... Are these signals from the fuel rail sensor?

Quote from chipit: But to make this clear ... no we don't over-ride any safeties.

Question from skywalkerrun: so clearly i need an explanation on the primary and secondary correlation?

Quote from chipit: Correct me if I am wrong or misread your stance / opinion.

Answer from skywalkerrun: I beleave that you "have" "Quote from chipit": "misread your stance / opinion"7 "Un-quote". as i am only asking you what is happening to the primary & secondary signals as you state that you intercept them....

skywalkerrun, if you are seriously interested in learning about 0-5 volts signals, signal emulation, the interpolation of these signals, and the correlation of these signals between one and another I do not believe it is my place to disseminate this info.

In my opinion, forums like these are here for those that wish to eat the fruit, not to study the roots. Also, I am on the forum to help people see the benefits and for those that have the experienced these benefits of our labour to share with others.

Sorry to be a stick in the mud of you but I cannot start to advise you on these points more than what I already have.

Clearly you say that we override Toyota safety protocols and others don't. You have no basis to form this opinion and in fact we don't override any safety features. The the addition of the EGT controller we are adding safety to what the industry has so far neglected.

I don't know about others but when people come out and slander with what is obviously no expertise, experience or regard for truth it really gets my back up.

Chip-it, I'll give credit where its due and its good to see the amount of involvement that you have on the forum and the backup for your product.

However if you are on the forum and you make statements it's also reasonable to ask questions. I know you've copped a fair bit of flack, in part because you are on the forum, but that doesn't justify getting worked up over a reasonable question.

I do not want to come across as trying to undermine your credibility as good competition is "always welcome" and strongly encouraged as it forces all other competitors on there toes and this makes better/cheaper products for us the consumer but what you are claiming does not appear to be adding-up and i am not sure what i am missing as far as the engine being able to protect its self when you are intercepting and modifying the secondary signals.

As an observer I think skywalkers questions are reasonable, were asked in good faith and weren't meant as an attack. As someone who has followed this debate I am also very interested. I would love a chip but I am concerned about the long term effects on the engine, particularly when it comes to boosting injector pressure.

Like I said your support and involvement is great and on the whole it appears to be appreciated. Apart from one poster who was obviously trolling I haven't seen anyone trying to slander you.

I suggest you have another read of the questions, they are not a personal attack. Unfortunately if you can't see the questions for what they are then you need to be careful about what you say on the forum, and what claims you make. It's one of the basic principles that you can make statements and that people can ask reasonable questions on this forum.

Chipit, I am not interested in learning 0-5 volt signals, signal emulation, the interpolation of these signals as i believe that you are referring to VDB=Vehicle Data Bus (CANbus), CAN-H and CAN-L..... These are not what i am interested in at all.

I am also not out to slander you but was purely asking a few questions about what "you" stated in your own words so i do not see this as slander or word manipulation.

Here is the blurb that you written your self

"Quote from chipit": Clearly you say that we override Toyota safety protocols and others don't. You have no basis to form this opinion and in fact we don't override any safety features

"Answer from skywalkerrun": If you intercept the primary and secondary signal from the fuel pressure sensor and then manipulate it so that it elevates fuel rail press then hasnt a toyota safety feature just been compromised?

"Quote from Chipit": Chip It Performance ECU intercepts both Primary & Secondary signals and all value changes are made in correlation to each other, hence why we get more power than others without CEL issues

"Quote from chipit" I hope this helps explain this point clearly. Let me know if you need further info

"question from skywalkerrun": And so i asked a few questions sticking strictly to your quote of claims and now i am accused by you for slander???.... Still no answers to my questions?

"Quote from Chipit": the addition of the EGT controller we are adding safety to what the industry has so far neglected

"Answer from skywalkerrun": practically all vehicles brand new never come with EGT... Whats changed?

"Quote from Chipit": I don't know about others but when people come out and slander with what is obviously no expertise, experience or regard for truth it really gets my back up

"Answer from skywalkerrun" I agree with you 100% on this one but less the slander!

Hi folks,

I've been unwell and in hospital for a while, and truely, aspects of this forum have kept me entertained beyond anything on TV...this discussion is great, its getting realy interesting and spirited... oh, how I hope the moderator doesn't shut it down. Come on lads, don't stop, it just getting really, really interesting....I might even be convinced to get a chip now I am out of hospital and back on the road ...and back "off road".

brogers, hope you get well soon....Nothing like a bit of spirited debate in a forum for entertainment

[barryswanson Senior Member Find all posts View Profile Close barryswanson]

Skywalkerrun, if rail pressure is too high the fuel limiter opens and relieves the pressure. The chip does not alter this factory inbuilt safety feature.

Modifying anything may or may not be compromising its integrity. Thats the risk you need to be prepared to make.

[barryswanson Senior Member Find all posts View Profile Close barryswanson]

I don't think anyone's trying to do that Rob, or upset you. Matter of fact, I am considering one of your chips for my 1KZ-TE.
I think it's just a case of trying to understand how you get more torque/power without increasing the heat factor. It would seem that most members are getting a decrease in the EGTs using your brand of chip and it's not a small decrease either. Around the 50 degree C which is quite a bit. I find this very interesting and in theory this would put less strain on those seats and the injectors while producing more power. That's quite amazing really when you think of how the basic principles work for the diesel engine in general.
What would be the affect if the customer kept the standard exhaust system and didn't install a high flow 3" system?

He keeps the EGT's down buy increasing boost as well, maintaining the correct air/fuel ratio. Other brands increase fuel only and make it a richer mix and in diesels that makes more heat. Opposite to a petrol engine basically.

Maybe its got something to do with my easy going type first and worry about what I have written later attitude....
However from my point of view Skywalker does come across a bit "cocky" or "negative" with all of the "quotes" and formality.

Entertaining, YES
Informative, YES.

but the "tone" is getting a bit serious for me.

The positive in Skywalker's bull doggedness in continuing to probe is that we learn more. (Which is what this forum is about)
(There you go!! a little back peddling to balance out this reply!)

Again this is my perception and I'm a gentle giant. ;-)

Hope all is well Brogers. I've spent enough time in hospitals for a few lifetimes!
My Chip It has been installed close to a month now. Had three non start issues in the early days, but none since. Go figure.
Love the power two chips give while towing. Much more confident passing caravans etc. Just have to be sensible with the loud pedal and not get carried away. Maybe the 3" exhaust has got a touch louder in time? Drones a bit at certain revs/load.
