    There are a lot of factors at play here with regard to spool and I'm trying to conceptualize which of those are higher leverage. Just to summarize some of the variables.

    We know by altering the...

    That sounds reasonable. I'm just trying to get my finger on the pulse of the details with this one. The mass flow out the exhaust port has to be equal to the mass flow in the throttle body plus the...

    So the theory goes that 68/84 increases overlap and exhaust flow at lower RPM allowing for an improved spool. But with a single scroll exhaust back pressure during spool is higher and thus you get...

    I don't use PM systems, too much communications to follow up on, sorry. You can always email me though.

    When the single turbos came out prior to port injection several of us hit 700whp on race gas + meth. It's doable but unless the meth nozzles are properly placed gets sketchy on fuel trim bank to bank...

    With the JB4 controlling the port injection now we have a lot more flexibility. For example we can set the system up to dynamically reduce port injection flow as a function of meth flow, fuel trims,...

    Spent a little more time on this project and enabled spool mode, and moved the changes in. Those are posted as "SPOOL" maps in the MHD back end flash files for general testing. When additional spool...

    Finally getting around to looking at the new bog tables & logs in a little more detail. Our MT is at the shop so I've been going back and forth with Ghost & Donnie to evaluate things. Both are...

    Wait does this mean we don't need to give a free JB4 to the winner anymore? :)

    There are probably several more tables associated with that behavior that you'd need to modify it.

    Have you guys figured out exactly what each table change does yet?

    Is the "fix" cutting fuel as soon as you press the clutch so RPMs drop avoiding the bog logic? What happens if you do the same...

    Why is that crazy? We have maybe 15-20 335is customers pushing 600whp on stock clutch DCT cars using the back end flash map+JB4. Crazy is slipping on only map5 with stock turbos, lol.

    I would be interested to hear a double check on the "theoretical" injector flow!

    One of the techniques we use to alter IPW on the piggyback end is to adjust the fuel pressure reading back to the...

    We have them installed on our other three DCT test vehicles so I imagine we'll get them going on the 335is as well. But first we'll test how far we can push the OEM clutch packs. Just so we know if...

    You 800whp guys should just get a dremel out and modify the area to fit our larger single turbo filter. :)

    Also clean the filter often if undersized. It probably flows fine when clean but when it...

    Mulling over the data also.

    I think the primary concern is to address within the injection tables is if there is an IPW hard limit table somewhere.

    These tables seem to define the injection...
