Has anyone noticed anything funky with their coolant temps after flashing the "PPK" ZUSB?

I think the number that is given for the 135i N55 might be a PPK2 ZUSB. I am pretty sure my car thinks it has the 850watt fan installed now. I say this because the fan behavior seems to be much different now and my coolant temps don't seem to be in check properly.

The DME using tables meant for the 850watt fan when only the smaller fan is actually installed = less than desired cooling at idle and low speeds? Is this a possibility?

No codes are being thrown to indicate something is not working right, or at the right speed.

Finally got around to getting my VRSF downpipe installed to go with my PPK, I used to complain about barely being able to hear it in this thread with Factory Catted... LOL OMG I love this PPK now so much more with Catless DP!!

Not noticed any issues with mine (07/10 135i DCT), did you code a clear .MAN file to 62BMO or 63BMO module? When I flashed mine got a 'Brake-by-Wire Failure' message on the IDrive screen, coded 63BMO and all is fine.

I thought that PPK2 was the hardware side of things and only PPK1 was the DME flash.

Drop me a PM if you need any help

My thought was that with the larger front fan also came software specific to running it. Different output would require different voltage inputs to maintain the proper level of cooling?

I reset the module and cleared the DME error that resulted from the update... thanks though!

Anyone have time to assist on installation in the near future?

Anyone that can help please send PM. Thanks!

This is true, PPK1 is the tune and the PPK2 is the auxiliary radiator and the 850watt fan. There is no special tuning for the fan, instead there is a small relay circuit that is wired in to draw power from the battery to power the upgraded fan.

Thanks for confirming! Now the hunt for the auxiliary radiator begins!

Get your catless downpipes installed and you will hear it, it will be a massive difference.

Add a performance muffler or straight pipes and you will hear it

You were right LOL the Downpipe made the worlds difference, it is everything I ever wanted and dreamed of!

No problem! If you search around you can get the auxiliary radiator for a great price, picked one up used for $180 which included the ducting as well off of eBay. Also picked up both hoses off eBay used for under $100. The bolts, nuts and remaining parts can be picked up for pretty cheap new.

As for the 850w fan it sells for around $600 though you can get the fan shroud alone for around $120. If you get the shroud only you can install a universal upgraded fan within it for under $100 or so and save a nice chunk from the OEM upgraded fan.

I'm UK based so finding anything like this on ebay is virtually impossible

Any rough idea on cost of kit from the dealer?

OK, I see what you're saying, but I don't think it's accurate.

How does the relay know what mode the car is in? The car runs in multiple heat ranges which vary to promote efficiency while cruising and to produce power during performance driving. The fan spins at different speeds during these heat cycles to maintain the selected heat range. I've seen my car at 115c with 20% fan cycle and I've seen it at 110c with 90% fan cycle. The DME most certainly does have coded logic to control WHEN and HOW HARD to drive the fan.

The relay is only put in place to regulate voltage since you're bypassing the factory wiring/fuses. The upgraded fan is probably hard wired because the factory wiring is not rated for an increase in amperage draw.

Maybe I am over-thinking it, but I'd appreciate it if a tech who's experienced with flashing PPK1 and PPk2 could verify whether or not it's the same software version for both kits... Even stated in the PPK flash thread is that there is more than 1 zusb that gives the pops and burbles. So, how do we know we are actually flashing the correct ZUSB?

All OEM functions are retained and there is no flash for PPK2. The relay harness grabs power from the battery instead of the factory fan wiring for the increased amperage as you stated though it still receives the signal from the DME and the DME still controls everything as before without any coding.

This is directly out of the install guide and confirmed by a tech.

ummmm that is exatly my point. The DME controls the fan. Where the fan draws power from has no bearing on that.

You are confirming that there is no specific flash between PPK1 and PPK2? I am not too sure I can just roll with that... There are definetly variations of the PPK flash available and you don't seem to be able to answer that directly and definitevly...

I am reading that there is a ppk2 specifiction flash tune which adjusts the dme parameters for running the fan.

How much does a ppk flash go for on a n55 e92?

If you have the skills and the hardware, you can do it for free. Or you can get the full PPK2 package from BMW. I think I paid my local coder $75.00 for it and the Alpina trans tune.

$1000ish from dealer, less than $100 from coder. Hit up joe@topgearsolutions.com
