Anyway, Andrew did share with me they are now selling the ESS Direct Flash tune for the 335d. It's a handheld programmer, so not only does actually reflash the ECU the tune is reversable. This is an interesting development since the last time I conversed with ESS their tune was not available for US spec diesels. 55hp gains. I have an e-mail into ESS to confirm that this tune is in fact available for US cars.

If this is true, this would amount to a nice advancement in the area of true "tuning" options for the d.

Here's the tune...

So what is Andrew selling then? Is it the flash from ESS that has to be installed by a shop or are they not selling any ESS tune?

Not stateside but, I did find this:
I wouldn't imagine the physical fitment to be too much of an issue. However, getting the ECU to play nice without a DPF could be another story.
