Faster warm up
Basically, I would like to the car to warm up faster.
The temperature gauge works, verified on ebl. I don't believe the thermostat is defective, because eventually it reaches minimum operation temperature (180 degrees F).
Some of the modifications, I have done do effect the pace at which the car warms up. I have a hybrid tpi/ Cadillac intake (with no thermac prevision) and no longer have an ac condenser in front of the radiator.
I am moderately confident the only modifications that I should pursue are ebl code related. I expect that I can change timing and fuel tables to warm the engine up faster, but I have not done enough research to find the specific changes necessary. Anyone have some insight on this?

Re: Faster warm up
YOu could put in a 195stat for winter. You may also be able to modify the cold timing spark table and add in a little bit of timing to get things a little hotter when the engine is cold. How long does it take to warm up now?? Are you running a clutch fan or electric??

Re: Faster warm up
Replace that exhaust flange spacer with a working efe valve. That will block exhaust flow on the passenger side and cause engine to warm up alot quicker ... well, providing you have it on your car.

Re: Faster warm up
Look at the 'SA - Coolant Comp Spark Advance' table. In the stock calibration the area of 32 - 68 C, 40 - 30 KPa VAC is low. This pulls timing to dump heat into the engine and exhaust. You may be able to re-work this table to better suit your needs.
Hopefully you haven't drilled a bunch of holes in the thermostat (seems a lot of folks recommend that). Doing so bypasses a lot of water. Only need one 1/16" - 3/32" hole to bleed air.
Also check that the fan isn't coming on at too low a temperature.

Electric fan is coming on at the prescribed 210 degrees F.

Re: Faster warm up
Here is a datalog from today. Obviously I need to work on the OL fueling tables as the engine roams a bit when cool. And for some reason the motor dies as I'm pulling into my driveway at 9:04.
