In order for the ECM to allow lead burn you need to either "spoof" the ECM into thinking the following temperatures are present or get these temps to actually occur:
Please note these are the parameters I have found to apply(by installing "hundreds" of gauges  ) to my 2002 Insight and may not be the same for your car. We know that Honda made many parameter changes throughout the production run of the Gen 1.
Ambient temp is above 80 degrees. I "spoofed" this temp to always be above 80 degrees by moving the temp sensor located in front of the radiator to laying on top of the manifold were the water exits the block to enter the top of the radiator.
Intake Air Temp above 120 degrees. This temp was "spoofed" by relocating the Intake air temp sensor from its OEM location from the tube between the air filter box and the intake and placing it inside the added Warm Air Intake hose about 8 inches from the catalytic converter.
Water temp in the block above 160 degrees. This has been the most difficult temp to control because I actually want this temp to be above 180 degrees to help the engine run more efficiently. Even when the outside temp is above 90 degrees, if you are always in lean burn and not running the A/C, it is hard to maintain a water temp above 180 degrees. First I always start by pre heating the water and oil to 180 degrees for 2 hours before driving the car. I also have added an adjustable grill block and extended the OEM belly pan under the engine to block the flow of air out of the engine block.
Hope this helps |
At least in my car, the only of those 3 sensor readings that I've noticed being critical is water temperature. Granted, I haven't been below freezing yet this year.
I haven't relocated my ambient sensor yet, but have still been able to stay in lean burn 100% of the time despite outside air temperatures of around 32f/0c (and losing auto-stop). I recall having been able to consistently get into lean burn with intake air temps as low as ~10c/50f, which is as low as it got before I installed my WAI.
Regarding warming up the block, it's probably just that I burn more fuel than you
but I also don't have any issues warming up. Even with weather nearing freezing I'm unable to do a 100% block yet because water temps start to climb into the upper 90's and even low 100's. With a 100% upper block and 50-75% lower block, I find I'm generally up to 90-93c (where it stabilizes as the weather is currently) after around 6 miles, but can get into LB usually by the bottom of the hill leaving my house, by which time I've probably hit 160f.
I imagine you're not doing any significant engine braking, since you're grid charging every night.
