The OBC says you are getting better milage but the JBD makes those readings inaccurate. My mileage has lessened slightly (fuelly.com) but my smile has increased greatly ;-)

The BT scanner sold with the JBD is a 1-VIN tool. There are BT scanners for more money that are 3-VIN or Professional unlimited-VIN.

Thanks Mikeo - BT tool is useful.

Can someone confirm that fault code 4674 is the tuner code triggered by the JBD at 100%?

Also, the two related shadow codes - 3F11 and 3F21 (accelerator pedal module potentiometer 1, 2).

I apologize to bring up the old subject, but I have had my JBD installed since last May and the car ran great until December at 80%. Now I can hear something that appears to sound like knock (electrical) and the car registers 5.7 seconds 0-60. No codes. Any ideas?

BMS JBD Tune E90 BMW 335d

How is everyone's experiences since 2012 with the Tune?

Any more 'long-term' updates? Have there been any issues or codes encountered?

I am going to put one in soon, but wanted to see if there were any more recent updates with users experience with the product, both positive and negative.

Thanks everyone,
David

+1. For a brief time I had it at 75% so I can gun it as soon as the car starts up and not get a limp mode. Then I kicked it up to 100% permanently and learned to be patient by letting the car warm up first.

I just bougbt a 2009 335d about 2 weeks ago and I'm eager to install the JBD Tuning Box to add a little extra power on the cheap. Does anyone have any experience with these much less expensive similar tuning boxes I found on eBay? Will they only work on European Vehicles?

Never heard of them. Most folks would say just buy a used jbd. I do notice they don't list a us spec 335d on their compatibility list.

Personally the jbd which I have works well and hasn't caused any issues.

They probably work just as well up to a point. Both say +35 HP so that means that they dont adjust up as high as the JBD does. It would be like running the JBD at 50% or so all the time and not being able to go higher.

Thanks for the response guys; I'm just going to get a Used JBD from someone on the forum as it's probably the safer option.
