I have had difficulties with the vehicle loosing completeetepower and stalling.
It has been established by Chip it for some time that the fuel pressure relief valve ‘spring’ is not able to take elevated tunes
In addition to the intermittent stalling I have not seen in the least change for the better in fuel saving.
There is more or less marginal change for the better of lower down torque.
I am yet to be convinced that to date this has been a advisable acquisition.
Furthermore the chipit is not water proof or even really water resistant. It comes with a huge forewarning not to get it wet and just comes with a flimsy bag to place it in. I mean how difficult can it be to manufacture a waterproof or water resistant container for it?
In regards to the loss of power and stalling I have been experiencing with the Chip it module – the scan gague thows up the fault code indicating ‘ fuel rail’. Probably as it is throwing too much fuel and creating elevated and risky pressures in the fuel rail.
Their 30 day money back warranty isn’t worth the paper its printed on as it openly states on their website “The 30 Day Money Back Guarantee does not apply whereby customers change their minds.”
For around 8 months or so they have been endeavouring to resolve the loss of power /stall, with the primary supply of a ‘shim’ to be placed in behind the spring of the fuel pressure relief valve.
At this instant they offer an added piece being a blank ‘billet’ to take the place of entirely the fuel relief valve – effectively removing this part. So that would entirely void any factory warranty and I don’t think its very safe to be removing a pressure relief valve safety structure in a crd rail which runs at elevated and unsafe pressures.
Other issues include in the elevated rev range you will get a rapid loss of power and next it will return, like a hopping/kangaroo jump feel.
In my communications with Chip it recently – I was advised they knew some amount of months back of the problem I am experiencing – yet at no point in time previous to purchase do I recall seeing any information indicating or highlighting these potential issues.
It would appear they have identified several earthing issues with the 5 volt pick up of current units sold but they haven’t yet resolved this.
Seems to be a very widespread story after you search various forums so I presume chipit still have a lot of R&D to do. They make claims concerning being Australian made but I’ve never seen any pictures of their manufacturing section and I wonder how real those claims are since they haven’t got the Australian made logo which is very uncomplicated to obtain of they are in reality Australian made.
Check their fine print. It states “CHIP IT can provide, at an extra cost, a 3rd Party Engine Warranty for up to $5,000 engine coverage” and on a CRD engine 5k wouldn’t even cover a pair of injectors. Doesn’t display much belief in their merchandise if they wont warrant the engine. The engine warranty is simply for 2 years maximum and they additionally state “only when a Chip It Module was purchased WITH the OPTIONAL CHIP IT EGT Controller.” Funny this is all hidden away in the fine print on their website and not mentioned in any of their advertising. I wonder how many have fitted a chipit not knowing the complete story and what they may perhaps be up for if there is an engine blowup or insurance request.
They additionally worryingly state “this modification is for racing or off-road use only and that use on road is not allowed in some states or territories.” So fitting a chipit may possibly not just be illegal but probably risky in that it may perhaps void any insurance claims in the event of an accident.
Personally I have detached the chipit from my vehicle after so many limp home problems and will at this time simply run the vehicle in standard form as its not worth damaging my expensive vehicle or engine for a a small amount of kilowatt added power.
