So I recently got a nanocom e2 and have been graphing data with it. The data logging feature of it is great, it has really helped me to understand how my Td5 has been running.
A couple of questions though for some more experienced nanocomers:
-Once my engine is warm, my coolant temp regularly jumps 2-5 or more degrees and a graph of it has spikes all over. I would have expected something a little more smooth. I've cleaned it off and the spikes were reduced, also don't seem to have any air in the system. I'm wondering if this looks normal or that I've got a bad sensor. I've attached a portion of my graph. Anyone else care to upload there's to compare?
-I live at 1320 meters, which according to basic pressure charts would be 87kpa, and that's about what my ambient pressure sensor is showing. However, the max turbo pressure I've seen (second gear, 3000+ rpm, floored, going up hill) is 148.
I found borntobemild's post at http://www.landyzone.co.uk/lz/f8/nanocom-reading-104682.html and figured out my theoretical max pressure to be 87kpa + 117.2 = 204kpa. Then it would be down about 14 percent (101 kpa at sea level versus 87kpa here) which would finally give me a max of about 175kpa.
My MAF isn't connected right now as I'm waiting on a new one, but would that influence turbo pressure? And can I rightly assume that 175 is a number I can try to adjust the waste gate to try to get to? (Once I get the new MAF)
Thanks in advance for your wisdom....
