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.

Does your JBD put codes in that need to be cleared before taking to a dealer? I am planning to run only at 75%. Not under warranty with BMW but I have a 3rd party warranty to 100k.

Would rather not spend another $120 on Carly + Wifi adapter to clear codes.

I can't say for sure, but if you've ever gone into limp mode because you got on it too hard before the car was sufficiently warmed up, there are probably codes stored somewhere, even though you can easily cure limp mode by restarting the car.

If a dealer finds a code related to some type of fuel pressure irregularity, which is what the JBD would cause, the odds of the tech jumping to the conclusion that you had a JBD installed are probably low. That said, your safest bet, obviously, is to find a way to check for and clear codes.

Thanks. I guess I will have to see what happens after I install it.

I saw that happen once, and only once. I have had the JBD installed for about 3 years now and the only time it happened was the first time it was plugged in.

FYI use torque instead of carly if you want to save, its much cheaper and has mostly all the same capability. Definitely capable of deleting codes.

If you want a poor man's JBD/rail pressure mod, I found it out.

Electrically savvy, so I tried a voltage divider. Oddly, the ecu did the opposite. With more testing, I found a 39 Ohm resistor in line from ecu 5v line to the sensor makes the sensor report to the ecu as .43v lower. In the spec sheets, it's about 4v at 1600 bar, from what I recall. I lost the table, but .5 v is about 200 bar increase. So I'm a bit below 1800 bar, which is the reported max pressure.

It's a flat offset, with meter testing the .43 v doesn't change whether at WOT (when ecu requests 1600 bar) or idle. That means the sensor reads 200 bar low whether at idle of 300 bar or max 1600 bar. So idle 300 bar becomes around 500, and the 1600 wot becomes around 1800 bar.

At idle I did a fuel flow load test, 700rpm idle, AC on, defroster on, headlights on, fogs on, and trans in D. On torque BT tool, normal (jumped resistor for stock reading) about 2.0 l/h, with the resistor active it dropped to about 1.5 l/h.

This means that messing with fuel rail pressure will throw off your mpg readings on the dash!

Can someone try this with the JBD on and off? I'm curious, it will give a clue.

Of course this is not a real number with the mod- but relative. Since it is a linear offset, the low throttle , low load pressures have a bigger %. (500/300 is about 60% but 1800/1600 is 12%).
