I cant do a torque launch with accurate numbers because im using a OBDII reader to get these numbers and it counts the actual revs of the axle (i think the abs sensor counts this) and every time even if i lurch a little but from torque braking it will set off the count and give me slower times. another thing is my stock brakes wont hold my car if i torque brake past 2100rpms i think thats when the turbo starts to spool and my brakes just arent good enough to keep it still |

Anyone facing below mentioned problem after tuned for F30? :
"cut n paste from tuner" There usually is an immediate power increment felt after the installation of a piggyback. However, we met many who installed piggyback reported to us their car returned to stock car performance after a certain period of time. The period ranges between 2 - 6 months, and some as short as 2 weeks! This could be possible because the modern ECU are intelligently designed to go against and adapt to the faulty signals it receive from the Piggyback module.

Well, it happened, I just got a CEL light on after 2 days of use. Is this going away or there is something not right? My care was built january 2013 does this has to do with anything? i was happy to feel the "extra" power but not with a CEl light....
Any help, suggestions?

N20 JB1 installed in my F30 328i since Feb 25. When first installed, I felt an improvement but more so over the past few weeks, improving performance over this time. What about those who have their JB1 installed for months? No complaints from them. What about the E90 N54 and N55 army? Going strong I read. So, who is this 'tuner' you made mention of?

Even disconnect and reconnect the control box, just to be certain. Then again, it may not be from the JB1, you never know. If the problem persist, contact Terry at BMS and have LOTS of photos of your install ready for him. If CEL is still on, remove JB1 and see what happens.

The 'adaptive' transmission BMW have had for years. So if you do travel to wherever at a slow pace day in day out, you won't feel the piggyback's effect. Take the car for a real spin and i'm sure everything will come good again.

Installed it then drove for a bit and stopped to get something to eat. When I came back and turned the car on, the CEL was on and to make it worst I was about to go out to the Autobahn to test it......

I just noticed you have an N55 engine, not an N20. Make sure you follow the N55 instructions of course. Still the principle is the same. Best to chat with the 335 guys on the N55 thread above this one about your CEL.

I know some won't agree with me and that's ok, but I don't use Eco "Pro" at all as it just sucks as it makes driving my BMW feel anemic. Light steering effort, ultra soft throttle, and way to quick to shift up trans operation. It's not a 'sport' sedan in that mode. For those reasons I don't even use 'comfort' mode. It's become reflex now to start the engine and engage 'sport' before shifting into gear. It seems odd to me that anyone interested in getting a tune for more performance would want to be in anything except 'sport' mode. If MPG is a concern, then simply dip into the throttle less. The best method to control MPG is to know how to use your throttle. Being in sport mode and/or having a quicker more responsive throttle doesn't mean your MPG should or will go down, you control the throttle. To me comfort and Eco Pro are nanny's for those who can't control their throttle properly. I have the DH package which gives me a couple more chassis and drive train settings. But, even with the added settings I still can't set MY car to have driving attributes that I want. I want the sharpest throttle response with the firmest steering effort with "comfort" AT operation. I can't get that because BMW can't be bothered to provide proper programming to allow the driver to set things the way he wants them. |

Thank you. Very nice from someone who, in my opinion, is one of the most level headed posters on this site.

I live in a big city with lots of traffic everywhere, pretty much every day, so driving the car in Sport mode every time is very un-necessary. When I can, I do of course and the JB1 makes it very, very sharp, responsive & fast. We also have a very active police force here and the government has pretty much mandated a virtually zero tolerance for even driving a couple of km/h over the speed limit. To keep track of speed limits across our vast city, there are hundreds of fixed and mobile speed cameras (privately operated) plus police with radars, so 'spirited' driving is a big risk here. Lots of revenue raising with heavy fines & driver license demerit points. So although I like to take off quickly from the lights, I want to keep my license and spend my money when & where I wish, so Comfort with the tune is just a very well balanced setup, which works well for most of my driving. So it's not a matter of tuning the car (or not) and using Sport all the time. It's also not a mpg issue for me either. I need to and have to adapt to our conditions. Please do not mis-understand me. Sport Mode is GREAT and I use it when I can.

Here's my dyno on dynojet
Ron 97 (i.e. 93 octane) 8 Speed Automatic BMS Stage 1 M-Performance exhaust (not sure this made any difference) Run 002 gave the most "balance" results, 241HP & 365NM.. What do you guys think? |
