Good to hear Derek,

And welcome to the forum! don't forget to post in the welcome area.
We are a visual lot, so photo's (more like evidence due to the "undertone" of this thread ;-))of your setup would be awesome!

Just a little bit of humor, seriously welcome and enjoy the vast amount of great information you will find on this great forum.

all the best

Bernie.

Hi Derek

You state: "due to the rougher idle and noisier injection, which I attributed to the higher rail pressures"

This is not what the problem was. They were probably just cheaply made chips with poor electronics as NO RAIL CHIP increases pressure at idle.

Engine chipping experiences

Hi Derek

Hi Robert,
I would have thought the same thing - ie why change any factory parameters at, or near, idle in order to preserve idle quality? Nevertheless, the effect was noticeable and repeatable (ie only exhibited when the units were in use). I had surmised it was due to the ECU having to run extremely short injector durations (to compensate for the extra pressure) in order to achieve targets RPMs. But that's just my guess based on observation, what do you think causes those sorts of effects? It was evident on my R51 Pathfinder too, using another brand of device though.

Surely it would be nice if there was an INDEPENDENT magazine that could do an unbiased trial of the main units on the market so that the poor consumer can really get an idea of how the different brands and types stack up (acceleration runs, in gear overtaking, NVH, BSFC). I'd love to see a proper laboratory ADR fuel economy run done as well, to finally put some fact behind the snake-oil fuel saving claims made about chips and exhausts.

Cant talk for other manufacturers. but ours does not change ANYTHING at idle (circa 1100mv) or even to to 2200 mv.

What is fact is that other chips (or modules as some like to call them) do not adjust BOTH throttle signal values (thus why they dont get as good a power result as Chip It do)

What we use the Injector Chip (or modules as some like to call them) for is to go for out and out power IN COMBINATION WITH the Rail Chip (or modules as some like to call them)

Fact is you cannot get the power out of the injector Chip (or modules as some like to call them) as you can from the Rail Chip (or modules as some like to call them)

We prove it over and over again

However, if someone wants a injector Module (or Chip as we like to call them) we have these available too.

BTW Re: exhaust. The offer for someone to have a cheap 3" exhaust if we can use your car in Sydney for a day is still on offer. We need to remove yours, get a system rigged up and then within a few weeks have the car returned for test fit. Good way to get a cheap system

Let me know.

I have now Aluminised MS Systems for $890 + $60 freight.

Stainless Steel System for $1090 + $60 freight.

This is for both 120 and 150 Prado

This still includes the fitting kit (nuts, bolts and washers etc)

HI everyone,

Only a new and recent Prado 150 owner, but not new to a 4WD.

This is a huge thread to read! Seems that problems are sorted to date with the Prado chip it. And it seems great support from the chip it crew. The few questions I do ask,

Is the black smoke on the tune 5 noticeable, it would annoy me to see this in the rear mirror every gear change, or blowing over cars behind me. Is this what to expect from any chipping?

Is there a increased engine noise?

And are there many effected with the fuel average reading lower than what it actually happening? As standard it slightly over estimates to avoid running out of fuel, and would hate the wife to run of fuel because of a incorrect average reading. Yes I know the obvious would be to look at he fuel gauge!

Cheers

John

should not blow smoke till around tune 10. And then with 3" exhaust that smoke should reduce quite a bit.

If you have smoke at tune 5, you need to get the car checked out for possible blocked cat or gunked up intake manifold

Many 3 to 4 year old diesels are showing signs of this

BLOCKED MANIFOLD 1

SECOND PIC

SAME MANIFOLD CLEANED

THIS IS FROM OIL COMING THROUGH THE PCV THEN MIXING WITH THE EGR. Hence why filtering the oil with a "GOOD" oil catch can (see my prado point store) and blanking off the EGR is majorly beneficial

Engine noise increase or decrease depends on the engine and or injectors. We have heard of both situations occurring. If there is an increase in noise it is usually only when the engine is stone cold. Noise disappears when warm. We have a temp switch that can be fitted or stop the noise during warm up. You shouldn't need the engine chipped when cold in any case

EVERY CHIP on the market will display a lower reading on the computer as the ECU doesn't know there is more fuel going in. It just sees less throttle being used. Usually out by 1 litre per 100 kms

Correct, most people use the dash board gauge.

Hope this helps

Cheers

Merry Christmas to y'all
Rob;
I have a conundrum for you: first off let me admit I am no diesel mechanic but learning from your excellent responses. I was having a Provent installed (sorry got it here in NZ, the savings from customs and shipping helpful this time of year) last Friday at my friendly neighborhood ARB/4WD store whilst I was at work when they called and stated they didn't undestand the Provent (we are in talks and I need your expertise) then recommended a diesel filter. I was in the middle of a patient so was lost on the pros/cons of filtering water out of the diesel and diesel recapture so said go for it. Here's the fun part: ever since the filters been in, that 'noise' people talk about with accelleration that some attributed to the CHipIt is GONE. Same time in the morning. Slightly warmer ambient temps. Same vehicle (plus plumbed fancy filter). Same stretch of road. Same accelleration. NO NOISE. Does this make sense or should I check myself in to the 'resting place'? I should say this is an industrial looking unit with plumbing that looks the size of A/C hose. Also they left a spot outlined in the pictures by VXWesty for the Provent?!

Just a friendly observation of your "conundrum" ( a comment from the sidelines).....just the way I see it. You purchase a Provent from someone in NZ because its cheaper...OK....I can see that you must be short of loose change.....(if you are anything like most MD's you hate spending money on little things and then spend big on big things) ...the installer you choose has no idea what it does ....no surprise there, because many of the new breed of mechanics have no idea about such things ...but now you want to get advice or comment from Rob....mmmm, interesting. I'm sure Rob will give his advice for free, without a consultation fee.
Anyway, the engine noise is now mysteriously gone....maybe they removed that stray sheep from under the bonnett

Just having a friendly dig, don't get offended.

[ctkelleymd Junior Member Find all posts View Profile Close ctkelleymd]

Just to be clear, have bought from Rob (have the ChipIT and extol its virtue), kiwi doc's don't make what Aussie doc's make (that's why many flee to Oz), and I plan to purchase from Rob again (had contacted him for an order when this came up, thus my comment) the item is a genuine Provent and cheaper only in sense that when I purchase from OZ I pay minimum of $80 AUS (parity with US dollar not kiwi) freight (it's over the ditch, no roads) and pay minimum of $90 NZD customs for the privilege. I commented since he has been getting dig's on the noise issue, this was an unexpected benefit I thought might clarify matters, and the locals are good blokes--kiwis are cheap period. They understood what it did, they didn't see the point, remeber we don't have long dry stretches of road in the middle of nowhere here. Yes, I can take a joke, just don't ask me to say 'Fish n' chips'?! Go All Blacks!

All good Doc. I know your heart in this matter. I'll be happy to help. First print up the Oil Catch Can thread with pics and hand it over the ARB.

With regards to the noise, it is either the pump slowed down by the fuel dragging through the new filter or the warmer weather. maybe wait for a cold snap and report back if you could. Either way, I am keen to hear about it.

Q. Did they EXCHANGE filters or ADD a new one?

Q. Could you email me some good hi res pics of the new fuel filter and the plumbing? I was looking into getting some fab'ed up and kitted and want some ideas as to what is being fitted? BTW the better fuel filters are a good idea. Did they advise how many micro is that filter?

BTW, Hope the patient didn't feel any extra pain

Merry Christmas CT

i'd like to add another conundrum, my Prado also suffers from the cold engine noise with chip fitted.
always happens for the first few kms till engine warms up.
but my conundrum is that during the winter months it didn't make the cold engine noise or rattle as this is what it sounds like, and now the weather has warmed up, it is making the noise again.
So work that one out?
