Hi guys

I've only been a Cayenne owner for 6 weeks but I am loving this SUV, been waiting for quite a while to buy one.

I come from a tuning background, I used to run a highly modified HKS Twincharged Corolla back a few years which was built from the ground up by myself. So I am familiar with the scene but not with these beasts.

Anyway, I have been following some older threads about lowering the Cayennes with air suspension, looked at links, the dreaded air compressor trick and the RennTech piggyback module.

It seems to me that the 9ff, Cargraphic and Techart are the way to go.

I am in particularly interested in the Techart item, and note that this is a complete air suspension ECU replacement.

My question is this, why do Techart not just reflash existing air suspension ECU units like they do with DME units for modified fuel maps? Surely the air suspension ECU is the same BOSCH unit but with different software embedded within the eeprom?

Has anyone tried to extract the software from a Techart air suspension ECU and inject it into a OEM air suspension ECU?

 

no because that would be stealing

 

jajaja

 

That's spot on. Not cool!

 

Indeed 100% correct and I have always paid my way through life. What I was getting at was that it should be possible to edit the data in the OEM ECU to obtain similiar results - not that I know how just theory.

But then thats why we pay for the Techart item, for the huge development time and proven code.

Any chance of a price Mark?

 

i understand intirely what your saying (and agree) but is that not what every tuner does with a cars ecu?
my subaru has an ecutech ecu and the tuners "hack" into it and rewrite/overwrite info, and pull bits from it to enhance the piggy back ecu.
is that not also illegal? (they all do it)
and just courious...is the software (or whats written in it) copyright?

with my subaru (05 STI) i had to buy a licence from prodrive to access it.
we all steel information from the internet (et al) amongst otherthings.
images/script/etc???

 

Very good and valid point, I entirely doubt the TechArt code within the Bosch ECU is written from scratch from the ground up. Most likely it is hacked Bosch code, has to be.

 

have a look into lowering links ive got them on my motor and its cheap and easy to fit, theres a chappy up in brum called ramus porsche they supply a renntech lowering modula which replaces the oe ecu for the suspension and lowers the car to half what ever height it might be with the oe ecu in, google them they are very well known.

 

just had a look at there web site, and theres no mention on there about cayenne's ??
most models covered apart from the big porkie.

 

I don't see why not. Does it suck for the person who put the money into the initial development? Sure. However, competition never hurt either. Also, at that point, hopefully they've made their money's worth back already. Of course there is more than one side to this, and no one will ever be completely correct/right.

thats a stupid comment. just tap into the ECU yourself and create your own program, then it would not be stealing. If you want to share exactly how you did it so someone else can copy it, then go for it. After all its only your time and money. it sucks for you, but thats life.

But don't blatantly take an existing program that is for sale, copy it and use it for your own or distribute it, that is stealing. This isn't dl'ing the latest Windows7 update from the torrent sites.
