Any 35D Owners install this performance tune?

[Terry @ BMS]

We are already 15 pages in here. Might as well come to some sort of a conclusion as you've strung us all long this far.

A good way to look at it is a value comparison. So, what do you offer the X5D customer? In terms of cost and performance increase? Maybe we can find an independent party to test both and while considering price and ease of install/removal have them highlight each and what they feel what offers the best value and overall experience.

My customer will recieve a brand new ecu flashing interface (Genuine, not a cloned copy). They will have full instructions to how to plug it into the OBD port, take a reading from the ECU, email to me, I will custom tune it to tailor their needs and yes I can cater for DPF and EGR deletes, I will mail them 2 tuned files - One for Power and one for Economy. The customer can upload the power tune or switch to the economy tune if they are going on long journeys.
The customer can simply revert back to the Original tune in the event of going to the Main Dealers.
They can switch between Power, Economy and standard tunes as they wish.
If they sell their car they can use the same interface on their new car and remap it also etc.

Differences of custom ecu flash tunes VS plug in box into the fuel pressure sensor... Well do I really have to go there

As for the performance increase.. It really differs big time.

The drivability is so much smoother with the removal of flat spots from the map.
Better MPG
NO black smoke
Powerband spread across the COMPLETE rev range
Higher torque
More BHP

I can give BHP figures and Torque figures if I know the year and model of X5

RESEARCH, Go for it everybody. Google.com Remap VS. Tuning Box.

Please don't visit the sites that are commercially run by tuning box suppliers as they, as you know, are biased

And what is the USD cost for this loading interface and your tuning fees? I'm sure we can locate a customer with neither tune willing to try both and give his impressions of the value of each.

Do you honestly need to get somebody to test both of them? You are so thick to admit a tuning box is inferior to a new custom ECU tune?
I think you have alot to learn about tuning European cars:

I don't know how things work over there but here customers are interested in value. What they are getting in return for their money. So what is the USD cost for your tuning solution? And then how much better is it for the average customer than our $279 solution? This requires some testing don't you think? The JBD does not smoke and runs as smooth or smoother than stock with much less throttle lag. Mileage is improved slightly during low throttle use.

We can offer flash tuning with the dimsport setup and they can use an at home genius system to load it but it's a much more expensive proposition, and the gains are not much higher than the JBD. Not enough to justify 4-6x the cost.

Price of my package is denpending on what the customer wants, what the customer drives and what other modifications the customer has.

I do not believe that any tuning box including your own Does not smoke. I would believe it does smoke but the cat collects it in the system, Think about what is happening, you are fooling the ECU into thinking the fuel pressure is low and so the ECU pumps more diesel in. That is where you are forcing power from, you are adding extra fuel so yes it will smoke.
There is NO WAY you can fit a tuning box to the fuel pressure sensor and think the Air-Fuel ratios are going to be spot on. It is impossible.

Again, you mention the ECU flashes, there is a huge difference between an OFF THE SHELF tune which is basically a one for all tune, a generic tune for the want of another word and comparing to a custom tune. A custom tune modifys the map of the car where as a generic tune simply is an off the shelf file flashed over the original tune.
Now I am not slating or slamming generic off the shelf tunes here but more bhp can be got from a custom tune. I am sure you will agree with that.

Are the flash tunes you use generic or do you custom tune them yourself?

It is the basic Dimsport setup. Perhaps you are using the same one? Basically for $10k USD anyone can be in the BMW flashing business. When I've used it I've always done tuning, logged, changed tuning, etc. It's a slow proposition. In the case of the diesel while we can do things we can't do with the JBD all in all it is hard to justify the extra cost. In the case of the gasoline models it is far inferior to what we can do with the piggybacks.
