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. |
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?
