Does any one know anything about these ?




I found this connected to my ECU !
had the car 8 months and didn't even know it was fitted !
this is my first terrano and I thought it went well for a truck,
been doing decent mpg too !

Will be a tuning box, reconfigures the standard ECU for more performance, power and economy.

I figured that out,
what i meant are they any good ?
has anybody else had or got one ?

Take it off and see

Good enough reputation for me to want to buy it if you take it off!

What's happening with 'our terrano' tuning chip, any news? Regard. Bri

yes ray is working on it the first board company was not good so now sourcing another, will be a few weeks be patient I want 3 he gets it sorted, Rick

Hello guys,

Are we developing a "Terrano tuning chip"?

Is this the MAF Amp or something else?

 

[panelbeater]

get in touch with ray as i think he has them now.

he has just posted mine today

MAF Amp? How much is he knocking them out for?

MAF Amp? How much is he knocking them out for?

£50 + £3.50 P&P.

Here's what it does:
The original MAF over time, will become desensitised, due primarilly to a build up of dirt and other contaminants. Cleaning the MAF sensor certainly helps but eventually a largely stubborn deposit remains rendering the MAF less sensitive to airflow in the initial stages of engine speed increase.

You know that awful flat spot that occurs on initial take off, just before the turbo shoves enough air in that the MAF can't fail to spot it, and off you go, all of a sudden!

The worst a MAF amplifier will do is approximate the performance to original levels. Given that most manufactures "tweak" their vehicles to maximise the emissions/economy figures, there is also room for some additional fueling in the first 1000~2500 RPM.
So by increasing the MAF sensitivity the ECU will have more accurate perception of air volume, therefore fuel quantity to match the measured air volume will be provided.
All of this provides a much keener initial throttle response and faster spooling of the turbo, getting the engine on boost sooner.
Net power output will remain unchanged, but the driving characteristics have the potential to be much improved.

IF the MAF were less expensive, it would probably be worth considering it a ~30,000 mile service item!

Would this not cause premature failure of the original MAF

By amplifying it with the device you have devised, is it not some how making the MAF work harder than it should and therefore reducing it's lifespan or have I got this wrong?

It makes no difference to the MAF...

In very simple terms, you take the output of the MAF, and feed it into a chip that takes a look at what the MAF is sending, and then multiplies it by a number, and sends that to the ECU instead.

So basically instead of the MAF talking to a chip in the the ECU, it is talking to a chip in the MAF Amp, which then talks to the ECU, which means as far as the MAF is concerned, it still doing the same job of talking to a single chip.

we'll put... I could only of come up with a more complicated answer!
