Unichip @ The Flick Of A Switch

Hmmm.....

Read this guys

The way the standard Xede is wired, unplugging it means no engine running at all (you won't get Crank angle pulses, nor MAP sensors etc)

You will need to bridge 5 pairs of wires back into the ECU for it to be happy.

I can't imagine the Uni-chimp (spliced version) wiring will be vastly different to this.  TBO240 do you have the later 'plugin-loom' style?  That version acts as an extension to the factory loom, and routes the relevant signals via the Uni-chimp. 

Removing that means the car wiring is stock==runs stock.

Also, weren't Uni-Chimp releasing live bank switching? I think it is due in two weeks?

I have the plug in loom

I was thinking the hard wired one, that explains that.

Thanks for the feedback,

There is reason behind my madness, let me explain.

After a recent throttle body clean at the service dept of my original dealership, service advisor mentioned there was a reflash available of the software available that helps rectify the 'stalling' and 'rough idling' problem when the throttle bodies begin to collect carbon.

He knows I have the Unichip (hard wired, not pluggin) and because of that reason then the reflash wasn't available as it would play havoc with the integrity of the Unichip and it's current tune.

Hence, if being able to integrate a switch of some variety, turning it off and negating the Unichips signal input then such reflashes would then be accessible.

If it's a hassle I'mnot going to stress about it, but then agian if it isn't then 'why not'

But thanks everyone

I don't think this would work (Could be wrong) as the unichip bends the original tune so even if it is switchable the new flash will be different to the one the chip was tuned to bend.

Does that mahe sense?????

Exactly.....will be all over the shop and will require a retune

wether or not you have your uni-jip in place mean sweet F all to the factory reflash, it will flash happily away and all will be cool as far as its concerned, but you will need a retune afterwards depending apon the changes made to the factory tune when reflashed.

you uni-jip, along with all other strap-ons, inc my xede (the one and only), dont do anything to the factory tune in the ecu, they only intercept signals from the sensors and ecu, and BEND them to make the ecu see what it wants to see.

you want more fuel, you show the ecu more load on the manifold map sensor, hey presto, more fuel, and more timing, for free. the factory ECU is seeing the same load, it knows nothing,,,, nothing, just like the fat guy off Hogans Hero's.

but the Strap-ons only bend what they are told to bend, if you have a custom tune based on factory flash x, then get factory flash Y, and its boost setting are different, then your strap-on doesnt know this, and will continue to bend to suit flash X, if the flash isnt to different, you may be OK, but it doesnt take much to upsset these things, adding 1 deg of timing at a high load point can induce ping like you would not believe.

tell themt o keep thier new flash, unless you want a retune.

or piss your uni-jip off, buy an xede, stick it in, and have duel map banks at the flick of a switch.

On a side note, it doesnt matter if you have aplug in or wire in, there are still 6 wires that are cut/intercepted in the turbo, without a jumper, like chiptorque sell for the xede, your car wont run properly with the chip unplugged.
