Hi Guys,

Has anyone (especially Valboo, Manuel and Terranismo) come across this mod chip for the x-trail?

http://www.speedydelivery.co.uk/car-tuning-power/nissan-x-trail.shtml

Is it true what is being claimed in there? Does it have any effects on the engine in the long run? would it cause any damage?

For that price, I think it's too good to be true, but then, who knows?

Just interested in your feedback.

Interesting... Remapped EPROMS do work, however this is an external device that make the EPROM think different due to a fudged input. I would be curious to hear actual testomonies as par tof my brain is telling me this isn't right, and the effects would be minimal. It's not like a remapped EPROM that changes the timing curve spark and fuel delivery.

This mod chip is in fact an air fuel converter that cannot be adjusted.

Air fuel converters do work like: APEXi - SAFC II, but they do need to be calibrated by a qualified shop. This device sits before the ECU and fools it by altering signal to re-map the air fuel ratio.

You will find info in the SpecV section:
here is one

Also from APEXi

I will not be going there myself...

Jalal any product with a pirated 2Fast 2Furious picture for endorsement is enough reason to run away :hal: The QR25DE has yet to be cracked (Technosquare is the one closest to doing it) and the only EPROMS or Chips offered that really work on the X-Trail are for the YD22DDTi diesel and SR20DET turbo gasoline engine.

Quite frankly the claims are bogus because a simple chip cannot give the QR25DE that much horsepower. Even an aftermarket ECU would give our car minumum horsepower without built internals, cams and cam gears and a raised rev limit.

From what I've seen, that sort of HP gain is more likely to be possible on turbo engines where the electronics have a say in the boost pressure.

everything were said.

My other Nissan engines experience: It's not easy or cheap, change Nissan ECU Settings, wish sometime the guys at Technosquare or JWT made that job.

Yup, as well as an engine that can hold a bumped redline. The QR cannot on stock internals.
