Stock JB4 logs and oil temp/IAT info

Got some logs on stock map 4 with the JB4, timing looks beautiful on 93 octane. What is nuts is that the ECU actually targets up to 19 PSI on it's own, presumably during overboost!

http://www.datazap.me/u/paradoxical3...log=0&data=1-4

http://www.datazap.me/u/paradoxical3...-stock-2nd-log

Tomorrow I will get some that are more comprehensive (3,4,5 gear pull to redline) but this was the best I was getting since traffic. Car is stock except for a VRSF downpipe.

Some other info: When the electronic coolant temp gauge first says "ok," the oil temp is only 140f. This is NOT ok! Once the marker is in the middle the oil temp is 180f, which should be fine. I think this will be a useful marker for people - knowing oil temp is 180f at the middle setting will give a more concrete point of reference.

The stock intercooler sucks. On stock boost I was hitting 120f intake temps with a 60 degree ambient, and that was just on a 2 gear pull. I would not be surprised to see 140f temps on a 3,4,5 gear pull. This doesn't surprise me considering it is the exact same part number as the 335i intercooler, except running 6psi more boost... I ordered an Ambient Thermal Management intercooler that will be installed on Thursday or Friday.

Normally I am a huge Evolution Racewerks fan, but I have my reservations about the sheer size and relative pressure drop of the intercooler.

ATM had published data about pressure drop and IAT reduction that was verified by a couple of third party reviews, the welds looked high quality, and the core has decent fin density. Normally I do not like stepped core designs as I believe they have negative effects on flow but in this case it seemed like the best option.

Excellent. Please update after installation. Very interested in delta, especially re heat soak....

Thanks for posting. Map 1/2 will be pretty useless, Or even map 5 for that matter if it's already targeting 20psi. How did the timing, lpfp and hpfp look?

You can see all the data including timing, hpfp, etc by selecting the parameters to show in the datazap log viewing program Everything looked good.

Hahaha yes. I'm sure terry will come up with some future firmware for us. I'm not a huge fan of constant map 6 runs so I hope he creates some nice base maps.

Those trims are in the dirt! HPFP will probably give us issues before the bucket does. I can't believe it's targeting 20.5psi on overboost. Then a taper to around 15-16. The stock map should be a beast with pure stage 2 on pump even.

The throttle pull seems far higher than on previous N55 logs.
Maybe there is some tuning potential available there to keep it at least in the high 80's and 90's

Nice. I can tell from the way that it drives as it gets hot that the stock intercooler is shit.
