First Morning with a Blocked Grill

I will probably block some of it tonight. I am also going to get a scanguage to monitor the temps. It looks like an interesting add on for any car, not just the prius

I blocked 1 section of the lower grill - didn't have enough materials to do more. It was very hard to do, and I will have to cut it into individual sections. I don't like the wavy look as it is now.

I took a trip from Sumter, SC to Charlotte, NC over the weekend with just the top grill blocked. MFD indicated 43.8. After fuel up fpr return trip (I fill at half tank all the time) it is currently showing 48.9. A big improvement.

My scanguage should be here Thursday or Friday. I looked at Can View but it looked too hard to install. After ordering the scanguage I sam the Dash HQ - I wish I had waited as it looks much neater with the visual effects.

I have searched the forums for the prius lower grill block that had the holes in it that you could plug. I know I saw it in one of these posts. I think that would be much simpler for the lower grill, and I could place and rem,ove plugs as the temperature required.

I'm new here and have not seen the removable plug block.
For the lower grill I cut two 3 foot sections of insulation and lined up the sections against the grill noting where notches need to be located. I cut notches out to allow the foam to slip in closer without showing the cuts. The glue on the foam seems to be holding the strips in place well enough for the few months I'll leave it on and the foam has a smooth appearance.
I'm planning on a Scanguage...What is a Dash HQ ?

There is a thread for it in the Mods forum - I may have the name wrong.

This is a sensational thread .. found it & went thru it last night.

Huge thanks to the numerous posters who led the way on this and provided volumes of feedback and advice.

Installed the upper grill blocks this AM. Will block 1/2 the bottom later today.

I'll have another question later but the answers here have some bearing.

When fully blocked the OAT gives distorted reading. Will the OAT give distorted readings at highway speed:

1 When the lower grill is only half blocked?

2. When only the upper grill is blocked?

Edit -- did upper half of the lower grill and after it cooled took a 20 mi drive.
Seems to allow the passenger compartment to warm up quicker and better mileage by a noticeable factor. Drove by a bank temperature sign that was 4 deg cooler than the OAT indicator. 180 mi drive tomorrow in 32 to 50 deg and check temps with a good thermometer.

You might be thinking of hybrid effects Hybrid Effects - Grille Block I checked this out first. As I wasn't as worried about looks. I cut a piece of vinyl siding and connected it through the lower grill with toggle bolts. It's been working fine for me.
