Removable Tuning Chip

[DEF33]

Finally had a few VCDS mods done and have Audi connect sorted etc.

Now thinking about a removable tuning chip and was wondering if anyone else has one fitted and if there are any recommendations.

A couple of people I know have used CHIP Express, and had good results in an A3 and an A5.

Any recommendations for a stock A7 (204bhp non Quattro)

You have dpf ?

[DEF33]

i assume yes

I was interested in this too, was thinking of a revo stage 1 but like the idea of a plug and play chip tune that you can easily remove putting things back to standard

[Gazwould]

Depends on what tuning box you get , a tri channel would be best .

The trouble with any box they fool the fuel rail pressure sensor into requesting more pressure thus fuel , the extra fuel used isn't accounted by the ecu and will be a mpg loss not a gain as indicated .

Single channel resistor rail pressure fooler will make the fueling rich and have more soot for the dpf to deal with .

A tri channel has boost pressure adjustment to help .

Not many advertise how many channels their chip offers,only one i can see is the DTUK CRD3+ Tri-Channel Tuning System - Audi A7 3.0 TDI 245 PS V6 Stage 2 (CRD-T)

I have just emailed Chip Express to get a bit more info from them. I will update if i get something back. All reports i can find online are positive and drivers reported more responsive car, smoother power delivery and increased economy. No real technical results i can find, just drivers own impressions. I know 2 people with them (A5 and an A3) and they swear by them.

Reply this morning from Chip Express.Our chips are DPF, EGR, EGT and ECU safe.
The CHIP Express™ system works to take advantage of the engines lean running to enhance performance via the re-configuration of the injection system, all within the safe parameters of the engine. Superior atomisation provides uniform and optimised combustion during each injector duty cycle, for better performance efficiency at all engine speeds, as a result of this turbo boost pressure levels will also build up much sooner without exceeding safe limits, reducing throttle lag and making for a more linear power delivery.


Some customer feedback:

Neil from Milnathort with a Audi A7 MK1 3.0 TDI 204 said: My chip on the Audi A7 was perfect in every way, instant power and on average a minimum of an additional 6 mpg. Never had a problem from easy fitting to recent removal. I recently sold my Audi A7 and bought a Volkswagen Touareg 3.0 TDI. As I wanted to chip my VW I asked for advice as to whether I could swap this onto my new car, fully expecting that the chip may need reprogramming at a price, not so! CHIP Express confirmed that the chip will plug and play without any need for adjustments as both the Audi and Volkswagen use the same engine. I cannot recommend the product and company highly enough. Don't go for cheap and nasty. Go for trusted service, absolute honesty and reliability from the guys who know!

Thats sounds like a bit vague sales pitch. Ask them if their system is a dual or tri channel as mentioned by Gazwould, it would be interesting to know. I see Racechip offer engine warranty with their chip installation

[Gazwould]

Just remember these better mpg are completely false , the fuel rail pressure is fooled thus the ecu's fuel accounting is fooled .

It's so simple to tune a diesel , just inject more fuel .

Any updates, did you take the plunge on one yet?

I was looking at a tuning box too rather than a remap as im not sure how long im going to keep the car, at least i can take off the tuning box and sell it on.

I was looking at the Race Chip:

I did take the plunge actually. Dealing with Chip Express was very easy and the box arrived within a day. Fitting was a bit of a pain as my clip was broken and could not get the cap off. Bit of wrestling and it was sorted. Have been running it for about 1 -2 weeks now, and i have to say as a non professional opinion the car is definitely more responsive on pick up, and acceleration. Much smoother and quieter. Also the MPG on same runs as Pre chip up to 56mpgs rather than 46mpg approx. But i note that this may be a little false from others comments. Overall, very pleased and glad i took a chance.

What does the wallet say?

[Gazwould]

Yes totally false mpg readings .

Is it tri-channel ?

[DEF33]

Don't think so. Had a good chat with the guys there, and thought i would take a chance. Very pleased i did, car feel very different, more responsive, quieter, and much quicker on pick up. I have the 200BHP model, so guess the smaller engine reacts better to a bit of tuning, over some of the higher spec engines.
