Best tank ever!

I have the mpguino calibrated, but have not got around to testing yet because the mpguino only goes to 2 decimal places. The amount of gas used during idling is very small, so it's hard to find a stretch of road long enough for me to see the differnces between p&g vs throttle blip. I'll continue searching.

More updates:
I recently filled up and got 27.69mpg using my throttle blip technique! BEST TANK EVER!

My previous best tank (using eoc and all aero mods installed) is 27.56mpg!

My previous 3 tanks using p&g only I achieved 25.1-25.4 mpg.

Yes, I agree, older cars with older ecus may not have the throttle fuel cutoff in their fuel maps. However this may simply be that not everyone has a good enough obd2 scanner to test my theory.

But if anybody out there wants to test my theory, I would help us figure out what cars work and what cars don't work

I'm thinking this technique works best when doing p&g at highway speeds as the distance travelled during the 0.00gph is greater at higher speeds, thus out weighing the fuel used to initiate the blip, thus bumping up the mpg averages. I noticed even the sgii stops displaying 0.00gph at below 30mph.

So at least the proves that I'm not WASTING gas by throttle blipping.
