Some interesting data collected today on a local 335d with an Evolve remap stacked with JBD on 0 and post IC/pre IAT water/methanol injection. Temps were 98F and ~41% Relative Humidity. Setup utilized a 200psi pump, 550ml/min nozzle, -20F washer fluid (~30% Methanol/70% water), and a Snow 0-5V MAF based controller fed with the MAP sensor. The Map sensor puts out ~1-5V based on intake pressure so the injection response is boost-based, even though it‘s using a MAF controller.
Very significant impact to intake temps during full fuel runs, as well as significantly reduced temp recovery time post runs. Also good impact to HP based on OBD acceleration data and Gtech results (will try to post Gtech plots tomorrow). Max EGT’s measured were 544C with and 537F without injection. Still well below temps seen during DPF regens.
