After all this time I still don't understand all the parameters for how long the initial (cold-soaked) ICE warm up takes. And what about if it's semi-warm?
Big differences Ive found from hot summer day to a day like today(52F) or a winter day. Today mine fired and it took over 3 mins to warm up, Hot days that is about half the time...and winter it can be even longer. I guess this is where the grill blocking can help, I know I installed my license plate down lower to cover the grill, at least in middle. Not sure it does much though. Dan
I know grill blocking can make a big difference on the Gen3, so it definitely should on the PiP as well.
I saw a few pics somewhere on here using foam pip wrap, that looked to be easy and quite inexpensive. I dont use my PiP much from Jan thru march so have not looked into it too much, but maybe this year I will as these cooler temps are already showing signs of less EV miles and its only sept...
Grill blocking won't help EV miles. It's to help ICE warmup. Ok...back on topic. I just started a new thread about grill blocking.
I did not say that at all....If you read my post I said "my EV miles are lowering with the cooler weather" I guess you like to be "always right" with your posts??? lol
From SAE paper I read, the ICE shuts down when Cat converter bed reaches 500 deg F. I guess you can correlate it to coolant temp as the heat is transferred from exhaust to engine coolant with EHR. Therefore, outside temp would play a big role as well as the temp of Cat Conv from prior warmup.
In my case I do think it helps to some degree to do grill blocking for EV miles! My car is in a heated garage at 45 degrees f. When it gets colder than that the cars is at 45 degrees, doing grill block helps to hold that heat in as long as possible. The entire car stays warmer just a little bit longer and kools down slower. Maybe it does not really help much, but it makes me think so, so it must help! Right!
