1024kb: Specifically for VAG TDi motor. PD injection version.


Maybe You could try yourselve, check out what's possible. There's software/flash available online for this.

If you want your engine to last long time, get a proper tune by a pro. That's all I can say. Worth paying $$$ for. My experience is based on REVO, Superchips, COBBs (by a tuner in the states), and finally Mountune. I would not touch someone random without followers / good reputation.

This is why I will not be doing the job myself. I have no followers & a dreadful reputation.

Perhaps post on Vask.org.nz there's at least two guys on there that used to be agents for one or more of the reputable tuning brands.

I've been considering doing the same to my PD140 BKD - Maybe for it's 20th birthday :)

I have a Vagcom HEX+CAN OBDII cable etc, has come in very handy, but I don't stray past the basic adaptations.

Oh I have investigated, don't worry about that. With the overarching consideration that I haven't done this before & have seen some unfixable electronic messes in otherwise good vehicles. My friend has a tool that clips into the OBD of his BMW 335I, allowing him to upload any one of 5 different maps whenever he wants. At $500 I think that method is a freaking bargain. The equivalent for VAG is $1200 & not justifiable in my estimation. VW dealers touch you for $900 to upgrade your ECU map - profiteering I think - it's just a few lines of code being uploaded.

The VAG 2.0 TDi is available in at least 3 power outputs - 103kW, 125kW & 140kW. Having experienced the improved performance delivered by a 1-level upgrade in 2 different VW models, I know that it's fairly simple to obtain an excellent result with very little risk / downside.

There's endless prebuilt maps available via OBD Tuning forums, I've made the decision that I'm not going to be doing this on a regular basis so learning the requirements for success is not going to be a valid use of time & resource - I'd rather buy that expertise in for the hit & run install job I need.

Why mess with a 335i?  Safe to say that when it comes to performance, BMW engineers know what they're doing.....

 

I imagine the program your friend has strapped to the ECU adjusts boost control, since everything I've read on ECU remaps suggests there is no reserve power to be squeezed out of the N/A engines.

Because he can. Perfectionist who works hard & justifiably enjoys some fine assets. The BMW doesn't just have the tuned re-map - after buying the best example he could find, the car was treated to new suspension, upgraded brakes, an exhaust that could be mistaken for a sculpture, seriously upgraded turbochargers & much much more. A little shy of 500hp at the rear wheels now, yet quiet & very drivable whilst the car still looks very, very standard. I've watched some OTT experiments with the 35i engine, there's some real potential in there. My friend's car is nowhere near the level of stress & strain that would cause unreliability.

Per this thread of mine a few years back.

 

https://www.geekzone.co.nz/forums.asp?forumid=162&topicid=243781

 

 

 

I ended up going with Basil at Autopassion. 

 

http://www.chiptuning.co.nz/cars-skoda

 

It wasn't cheap, $895 back then and I'm sure it's more expensive now. However I'm really happy with the outcome. The care is much nicer to drive now, particularly when loaded up with gear and towing a load. The benefit in going with a proper tuner instead of a drop in chip is that they can also tailor it to what you want. In addition to tuning for more power/torque I also asked for the throttle control to be addressed. Basil sharpened it up for me, taking away that lazy throttle response off idea that VAG diesels have.

Sure, they know what they're doing, but so do their marketing teams.

 

Many of these brands use the same engine across multiple applications, in different states of tune depending on factors like the market (e.g. Europe might get a different map than the US), specific model, etc. The same engine might be in both, say, the 335i and the 1M, where it produces a bit more power.

If that were true it would hardly help BMW's reputation.

 

I don't know about other manufacturer but BMW engines have the same torque and power output no matter which market/country they're exported to (caveat here being fuel type).

 

The options package and vehicle trim may vary however.

 

 

 

The only other caveat I can think of is the V8 governor which can be removed on non M series to give a top speed of ~300km/h same as M3/M4/M5.

I think they may have meant BMW are using the same engine across trims or models and essentially just winding up the boost. I kind of preferred the old way where a 325 meant a 2.5L engine, rather than almost an arbitrary number now. My brother has a 440 coupe which has a 3.0L engine and god knows how many turbos or kW. Which is used in possibly thirty models (including Toyota). I would genuinely like to know how much variation is actually in those engines for the 45kW differences.

I was under the impression that electronic throttle controllers were very similar to magic smoke, & told the supplier that before he offered me a risk-free trial & good discount. I was initially talking to him regarding a bolt-on ECU box which only works with common rail motors, not PD injection. So he switched his patter to the throttle controller. A discounted risk-free offer is compelling, it said to me that he certainly believes in his product so I went ahead.

It took just ten minutes to install the unit & pair the Bluetooth app. Within a few KMS driving, I'd completely changed my mind - for the money, this is the single best performance enhancement available for vehicles today. $300 retail, $250 with a discount, $100 if you shop AliExpress.

I regularly demo the effect by giving my passenger the controller app, set to Stock - no effect. On a clear straight road, I'll hold my right foot steady on the accelerator & tell them to hit Race Mode. No matter what speed we were doing previously, the car goes nuts, the difference is crazy. Several people have bought for their cars immediately after my small demo.

Manufacturer settings may take into account things other than power and responsiveness.  For example they may dampen throttle response, to limit fuel burn.

 

I put i-drive's on our vehicles.  They plug in between the accelerator sensor and ECU and can be set to either boost or decrease throttle signal.  This makes a dramatic difference to either performance or economy.  I mostly have them set to economy, unless I'm towing.
