chipmydiesel chip testing log

No I've only done 1 full tank which was exactly 9l/100km. But I assume that would have changed a little over the next dozen tanks anyway.

I guess I can only just report the figures the chip gets and compare it roughly against the others for a reference. Then perhaps do a couple of tanks in the future with no chip to compare

[slickncghia]

ok guys, 1750km road trip complete. mix of great ocean road, and allot of 100 and 110km/h returned pretty much exactly 9l/100km for the entire trip. loaded with 2 people and a weeks worth of camping equipment half on setting 4 half on setting 3.

im not convinced the chip would save any fuel at all on the highway (as its just adding more fuel for each bang) i think if anything it would use slightly more on the freeway but tests without chip will confirm this

I do consider it possible that it might improve fuel economy around town though so i will keep logging this as it goes.

car is running great with the chip and I certainly notice the lack of power whenever i run the car without the chip or turn the setting down to 2 or 1

This chip seems in the doable basket - many are blatant cash cows for someone.

A question that Tony may be able to answer; Is there enough pulsing in the rail for a chip to make an assessment of engine revs?

It would seem that for any chip to do more than a resistor there would have to be some rev input as a minimum.

MAP would obviously be handy fine tune ECU parameters.

So what's the latest Slick?

Just to confirm, your kit just plugs into the rails pressure sensor loom. Yet, the site shows a loom with numerous leads and connectors; have you got a picture of what is actually delivered?

How are the economy and power figures going?

Been meaning to update this... I filled a tank on friday. 100% commuting swapping between 60% level 3 40% level 5.

My commute is 15 mins each way. all peak hour. stop start traffic. plus some runs to the shops for lunch.

8.66l/100km. It seems slightly more efficient in traffic than on the fwy which is wierd.

I was using level 5 (which I love the power, but someone told me there was smoke out the exhaust under heavy acceleration) So I dropped back to 3 and may nudge back up to 4 again.

Just did 300km trip this weekend full of camping gear and towing a steel trailer full of motorbikes so it will be interesting to see the economy when I use this tank, I suspect hight.


@RHK yeah one connection to the fuel rail, the other connection goes to the cable that would've gone to the fuel rail.

They're really isn't much info on the Web regarding chips
I've spent hrs researching them with no clear direction so I thought f it and got a cmd. Wasn't gonna pay $1400 for something that will only give me a 10% gain at best

[RHKTriton]

The way I see it, these rail pressure interceptors can only do a couple of things.
1. Measure the actual pressure.
2. Possibly measures engine revs via detecting pulsation of the high pressure pump.
3. Send a modified pressure figure to the ecu. (Basically a "smart" resistor).

The cost of components to achieve this is pretty cheap these days, even R&D recouped over a few hundred units would suggest around $300 would be fair pricing for this type of product.

For anything around the $1k plus mark I would probably want an ecu coprocessor, with it's own injector drivers.

Mmm food for thought RHK

[hammy]

Fitted mine tonight. Quickly realized the default setting of 3 wasnt going to cut it. Went through 4 and 5 pretty fast too. currently sitting on setting 6 with some noticable power gains.

[RHKTriton]

B interesting to see what your findings are Hammy.

The biggest concern I have with the eBay offerings is that the pics of the kits don't match the text, ie. Too many plugs and sockets when only instructing to plug inline with the pressure sensor or otherwise not enough when describing other connections.

I'm actually thinking of using some micro switches rigged up on the loud pedal to modify sensor outputs under a couple of conditions.

[hammy]

So far still using setting 6 and loving it. Find that under hard acceleration it revs out very quickly now. One thing im curious on is the fuel usage displayed on the dash. Ive never seen it so low and wonder how its calculated? Maybe it is being manipulated by the chip?. Will have to compare it to the actual litres I put in it next fill up

[trouble]

100% it is being fouled by the chip!

[RHKTriton]

So what's the latest slick & hammy?

[hammy]

Just done 500km trip with a heap of low range driving and plowing my way through 500mm of snow. I went up to 7 on the chip but found it made no difference in performance but it did smoke a fair bit so I went back to setting 6. One thing I hate about the triton is it struggles to pull on steep hills in low 2 at a slow pace but with the chip it seems to do it alot easier. Did this trip with another mn triton with a 3 inch pipe and a chipit, he had more power but his fuel consumption was very average.

[RHKTriton]

Good stuff hammy.

So you haven't cooked the donk then - that's good.

Its straight physics that more juice will get used with more power being produced.

[mattharding]

Following this with interest. In the process of finding a chip at the moment so many opinions from both sides

[RobG85]

Read this post through quite thoroughly.
Couple of things that need to be made note of.
These engines run 18psi from factory DOHC 4D56 2.5.
More fuel enrichens the mix, causing more heat, EGT should NOT be run any higher then 730℃ on short bursts. The DPF runs at 700℃ when doing a clean so the the system can handle high EGT.
To stabilise these higher EGT , boost needs to be increase, hence more air, more cooling and thus more power again. Putting en evo intercooler in with better cooling properties plus the fact it won't loose as much pressure drop across the core will again add further benefits. My question is, how much more psi is the rail getting? What is the fatigued pressure of the metal? What's the fatigue pressure of the injector springs in turn? If it's within safe limits I can't see why adding a further 3 psi would hurt. Personally I would adjust both at the same time, rather then fuel pressure increase then boost seperately. Rebuilt more then my share of engines to know the damage caused.

What dpf?

[RobG85]

Mine has a dpf.

[Cowboy Dave]

Your triton? Or do you drive a Pajero?

[RobG85]

MN Triton manual mate. And has a dpf.

[RobG85]

Had a few come through work with them in too

[baito]

What year mate? As far as I was aware tritons don't have a dpf?

[slickncghia]

Been using 4 for a few tank loads. Usually getting 8.7 to 8.8 l/100

Mostly commuting in traffic with the odd freeway

Did a trip to the snow fully loaded with 4 guys and gear no trailer and it was 10l/100 my car always seems to use a little more on the fwy than in town


Gonna try 3 for a few tanks

I see from an earlier post you have a 2010 model and you're a mechanic. The second bit means I shouldn't argue with what's in your ute I guess, no doubt you'd have a better idea than me as to what's what. Having said that, if your 2010 model has a DPF then it has taken 4 years for the news to filter through to the forum that they've started fitting them. Which seems odd to say the least. They'd have had to change the oils specs as well and there'd be a few other things they might change too and we've not heard anything about any of it. So this is all very intriguing at the moment.
