    Good to hear. The car is a rocket at 22psi when conditions are perfect.

    My car definitely feels faster than it ever has and I haven't even gone to map6 yet. I've also noticed when I go to pass someone in normal driving it feels like I have more power on demand. Anyone else notice this after getting some seat time with the bcm?

    Would make sense given my experience I described.
    You made the duty cycle adjustments in the app I assume?

    Yup, I've been making a few hits on every map and sending them in. I just sent in my map5 data, I'm assuming everyone is slightly different based on their supporting mods. Today driving around I got very excited about doing my suspension(hopefully soon!) With as much power as I'm making now it's going to be very fun.

    Again Iím jealous. Wish I could do suspension but Milwaukee roads would just destroy my car

    I probably wonít mess with map 6 as Iím content on just the e30 mix they have provided. Iím sure theyíll squeeze as much power as they safely can for it and keep the firmware updates coming .

    Luckily most of my commute is farm country, which makes for good fun...
    I agree with you on the map6 stuff... I'm not going to be adding wmi anytime soon... I think I'll be more than happy with a dialed in suspension plus I power I have for now.
    Actually, since we can switch maps on the fly I might run a lower map more often if I get better milage out of it and just throw the higher map on when I want to play. Plus the more we refine what we already have the better it's getting anyways... I say this now since my tires can't keep up anymore(Michelin pa4's)... I'm sure I'll catch the bug again once the ps4's go on and the car is lowered 😬.

    Man looks like they are getting this unit dialed in. Looks like I will have to jump on this! Especially at higher altitude I feel the car definitely struggles a bit, this should help.

    Yeah curious to know if the bcm provides a noticeable difference than without it on map 5, e30 mix.

    It should from what they are saying and what Iíve been seeing on the n54 forum. Gonna try to find some time today to get it on the car.

    My boost seems to have fluctuated decent amount since these huge temperature swings in the Midwest. Car was solid, now often itís not hitting more than 16psi in a given gear if the load isnít there. If I have all accessories off tho it seems to be more consistently about 19

    Nice. Look forward to your update.

    What accessories did you turn off exactly?

    I started in fall with shutting the air off (obviously robs power), then noticed at times boost seemed to be effected by the other accessories on like even the vents, heated seats, pretty much anything on. Of course this could just be coincidence and in my head as I have no raw data. I have been known to be crazy.

    Obviously I donít think it directly effects boost but something with the ecu maybe. Iím sure Iím nuts

    The ECU targets torque and not boost. It uses air intake temperature as one of the main parameters for the calculation algorithm so typically the colder it is the lower it will boost. At a certain point the intake temperature sensor is maxed out on the lower limit of 37F and stays pegged there. We have seen boost decrease more than it should when at that point.
    In terms of accessories haven't really noticed any variance.

    Well I couldnít get the plug to click back in place, so i gave it a break to wire up the BCM to JB4. Tried to plug the wire in and then this. IMG_0520.jpg literally applied almost no pressure and the thing snapped in half when plugging it in. Guess itís too cold to work in tedious crap.

    You can buy a dsub pin and tool to fix it. I use needle nose pliers to push the pin in so it keeps the pin and wire supported from bending and breaking

    Do this, then when reinstalling remove the plug from the Jack first. When pushing the new pin into spot one you'll feel a point where is fully seats. Once that happens then insert the plug back into the Jack.

    Probably not worth it then lol, I'm like an hour west of the city. That'll add more than on hour to get home. Probably best to just Amazon some or pick some up Monday. Let me know if you do want to meet because I'll have to look for some pins.

    Does that happen with the jb4?
    Have you tried the TCU tune? I noticed that it smoothed out the jerkiness in the shifting for me.

    I had dtuk and sold it due to the jerking during shifts at partial throttle. Had a couple times that were very violent shifts and I also have the TCU tune. I purchased the JB4 and have experienced none of that behavior. The post copied from above was without the obdii plugged in (missing data to allow the jb4 to work properly) and on older firmware. The 2 products don't even compare imo.

    Well after sorting thro a few options on amazon I ended up spending $45 on connectors and crimper
    Unfortunately there are a lot of options for crimpers so I just went with the one that was supposedly easiest to use. Closed barrel crimper.

It happens on all maps at different times in rev range depending on which map and what level itís set. Iíve even tried half a tank of VP 100 octane and half tank of 91 to bring it into the 95 octane range.

    What Iím talking about has nothing to with the transmission. The transmission shift seems fine. Itís as if the engine just shuts off for 150ms or so and then comes back with vengeance. I would best describe it as a prolonged shift ignition cut. Iíve tried turning Traction control off too. No dice.

    As far as support is concerned, I messaged TDUK. Andrew passed the buck to Aaron because ďhe uses different filesĒ. Itís been 10 days since I messaged Aaron directly by email. No response on this issue.

    I bet they know about this problem and have no solutions. In fact, I know they know because Aaron talked about it in his intial review. When he turned the box all the way up he noted ďnotchyĒ saw blade like shifts ďin casual driving scenariosĒ.

    Those of you who think Iím some kind of a hater or something need to understand that I donít even really care about the power that much I just wanted the Lag in D mode gone. Iím curious about the power potential, but itís not the end all be all.

    For the record, the DTE/DTUK TCU and pedal box on Minus 3 eco mode fixed my problem. I just donít think the power control is smooth enough for me. Curiousity being what it is (the devil himself) I may just drop the 2500 on the ABT box when I go back to TAG for new tires and my sway bars.

    Iím open to selling my DTUK power control for anyone who wants to try it. I wonít lie itís cool to be able to turn this on at a light and totally annihilate a 392 Hemi, non CS M3, or a non S C63. But for daily driving itís not smooth enough for me.

    To be fair, Iím super picky about everything. I didnít buy the C63 because of its clunky infotainment. I didnít get the M3 because itís exhaust sounds like it has an aluminum can rattling around in the muffler. I didnít upgrade to the RS5 SB because of rear head room. I didnít go for a great deal on an RS7 used because it doesnít have CarPlay.

    That said, I like the thought of being able to turn the piggy off all together which is why Iím curious about the JB4.
    I have had the same issues with DTUK/DTS not replying. I sold my DTS unit and the new owner is going to limp mode everytime he uses it now with no reply/troubleshooting info for him. Most of these cars are people's daily drivers and not just an occasional hobby so prompt product support is a must for me.

    BMS replies within a couple hrs 95% of the time. The best product support in the industry imo.

Iíve even tried half a tank of VP 100 octane and half tank of 91 to bring it into the 95 octane range.

    What Iím talking about has nothing to with the transmission. The transmission shift seems fine. Itís as if the engine just shuts off for 150ms or so and then comes back with vengeance. I would best describe it as a prolonged shift ignition cut. Iíve tried turning Traction control off too. No dice.

    As far as support is concerned, I messaged TDUK. Andrew passed the buck to Aaron because ďhe uses different filesĒ. Itís been 10 days since I messaged Aaron directly by email. No response on this issue.

    I bet they know about this problem and have no solutions. In fact, I know they know because Aaron talked about it in his intial review. When he turned the box all the way up he noted ďnotchyĒ saw blade like shifts ďin casual driving scenariosĒ.

    Those of you who think Iím some kind of a hater or something need to understand that I donít even really care about the power that much I just wanted the Lag in D mode gone. Iím curious about the power potential, but itís not the end all be all.

    For the record, the DTE/DTUK TCU and pedal box on Minus 3 eco mode fixed my problem. I just donít think the power control is smooth enough for me. Curiousity being what it is (the devil himself) I may just drop the 2500 on the ABT box when I go back to TAG for new tires and my sway bars.

    Iím open to selling my DTUK power control for anyone who wants to try it. I wonít lie itís cool to be able to turn this on at a light and totally annihilate a 392 Hemi, non CS M3, or a non S C63. But for daily driving itís not smooth enough for me.

    To be fair, Iím super picky about everything. I didnít buy the C63 because of its clunky infotainment. I didnít get the M3 because itís exhaust sounds like it has an aluminum can rattling around in the muffler. I didnít upgrade to the RS5 SB because of rear head room. I didnít go for a great deal on an RS7 used because it doesnít have CarPlay.

    That said, I like the thought of being able to turn the piggy off all together which is why Iím curious about the JB4.
    The last reply from Aaron to a post mentionning the jerky shifts and dash light error was him offering as a solution to "dial back some boost so it would butter smooth...."

    Meaning that they currently have zero solution for these issues.

    Get a jb4 and never look back. No jerky behaviour, you can add the all the boost you want with the bcm and no dash light error.

    When I do pull the trigger whatís the best way to get it in Cali. Have a buddy out of state order and ship to me?
    I think the user that posted initially had the issue due to the OBD not being present. This is needed so that JB4 can see the engine data which includes the gear the car is in and what it is doing. On higher boost the issue can creep in on some cars on lower octane pretty quickly. All that is required is for a value called Autoshift boost reduction to be adjusted. What it does is cuts the boost add during the shift to allow for a nice crisp gearshift.
    The ABT is similar to the DTUK from what I have seen in the install guide. They have just added a connection to the water pump to get temperature so they can have the unit inactive when the water temp is low. We have this feature direct from the vehicle data network via the OBD.

    Sorry just a quick question...is this piggyback worth it if i only can run 94octane? Im assuming from reading the recommended settings im only good on map 3 with reg gas at 94 octane?

    Yes, decent power is made on 94. Map 3 is considered aggressive. With some logging we can have a look if map 4 can be used as weather is typically cooler in Canada if that is where you are.
