    JB4 6/4 beta firmware posted

    Posted in the usual spot. Enjoy! Click here to enlarge

    6/4 Beta Firmware:

    *** Note install 6/4 interface first and then use it to upload 6/4 firmware ***

    1) Adjusted heavy part throttle wastegate mapping to reduce part throttle oscillation.
    2) Corrected bug allowing effective PWM limit to be raised an additional 0.4%.
    3) If the "mode" option under settings is set to any value greater than 0 user settings will not be reset to default during firmware uploads. Useful for those with custom mapping, etc.
    4) Enabled methanol mapping additive and overflow failsafe for user definable map 6 as well as map 3.
    5) Fixed bug with map 6 lower rpm boost values not saving.
    6) Fixed bug with false 2ABC code triggered at very high elevations of 10,000'+
    7) Added support for VC2/CMGS FSB by setting MethFlowMax to 100 and JB4 direct FSB by setting FutureUseD to 99.
    8) Changed unused "FpSafety" user adjustable to "FpMapping" adjustable now used for fine tuning fuel pressure. A value of 0 disables fuel pressure mapping. A value of 90 matches the previous setting and is the new default.
    9) Moved disabling adaptive FFPID from FutureUseD=99 to FutureUseD=98.
    10) Adjusted laptop steering wheel commands to only function if FutureUseD=1 is set disabling normal steering wheel controls.
    11) Added alpha "max cool mode" feature. Enable with menu 6 option 1. Disable with menu 6 option 2. Water pump and fan will run at 100% duty when water temperature is between 160 and 202 degrees F. At 203 degrees F the DME ignores the fan command but appears to continue to overrun the water pump. We'll keep working on finding a way to extend the fan range upward to make the feature more useful.
    12) Added WaterTemp, EGT,and AFR options to gauge hijacking. Note EGT is read from factory DME and more study is required to determine if there is any useful application for it as a gauge.
    13) Changed menu 2 to fuel gauge only options and added menu 7 for oil gauge only options. Now allows independent configuration of 7 parameters with each.
    14) Changed CSV export default naming to YYMMDD_HHmm where time is in a 24hour format.
    15) Changed "stealth gauge" mode to trigger over 50% throttle and added 15 second delay when going under 50% throttle before gauges return to stock operation.
    16) Adjusted interface "WOT only" to display properly if a log starts under WOT, added a separator between runs, and lowered threshold to 40% TPS.
    17) Adjusted Exp1 fields as follows. Default: AvgIgnRetard (degrees off maximum curve), FUD=3: LPH / 10, FUD=4: Speed in KMH / 10, FUD=5: Low fuel pressure / 10, FUD=6: EGT in F / 10, FUD=7: Water Temp in F / 10.

    Very nice

    Other people eat shit and die.

    Let us know if you notice a difference.

    The effect of the max cool stuff is what I'm really interested in seeing.

    The new firmware is working very well right now in my car. Absolutely zero complaints!

    Another JB4 will be going in E90Vader's car tonight Click here to enlarge Can't wait to see how well his car runs with his full bolt-ins!

    That's the only new feature I won't be needing at all right now.
    It's 18C and pooring with rain here at the moment.
    Not even nice weather to check the difference in performance (if any at map1).

    My car = Animal!!!!!
    Now I just need to log Map 6 default this weekend to see if it pulls even stronger then map 2. If it does, and looks clean I want to add 0.5PSI on every 500rpm band.

    Cars very quick up top. Blows the f***** doors of corn of the "COBB"...

    Ok, after driving around with this update for some weeks I can do a small review of the update.

    The driving.
    There was in the januari update a point in the throttle responce at about 70% throttle where the car "hooked" and took off. After a while I kind of liked it like that because I got used to it, and at first after the update I missed it, but now the throttle responce is like stock, only faster Click here to enlarge It makes the car more controllable (and drifting easier Click here to enlarge ).
    Drivability went from 80% smooth to 100% smooth!!

    The new display features.
    At first I thought it would be very handy to have the water temperature over the oil temperature. So I had that for about a week. But irl it is only informative for a very short time. I really want to know the oil temp and when the JB4 comes into play when on short trips.
    So I turned it off. Maybe for guys doing drag it would be handy in combination with the max cool option, but as a dd it's confusing and not really usefull.

    I really like the longer display of the secondary gauges! 15 seconds is great. Needs a little getting used to when I see the turbopressure on the fuel gauge say 0, but used to it now.
    Also it is surprising (to me at least) how fast 50% throttle is reached. Better though. No need to gun the car for gauges, and more time to look. At WOT most of the time I need to look out of the windows... Things happen fast like that.
    All in all a great update Jerry! Keep up the goood work!
