OK now I understand. Thanks!!!

I do the same thing in the talon. It still amazes me how fuel can be saved doing this.

My Insight has been teaching me a lot about lean burn driving. Something I haven't been capitalizing on when driving the Talon is low speed lean burn. I need to spend more time mapping this in that part of the fuel map.

I can't wait to see your results with the lean burn.

Good news - I got everything hooked up as far as getting the car into lean burn!

Bad news - When I flip the switch, nothing happens

It appears like I may have tapped into the wrong wire. I need to hook up to the MAF -> PCM wire and bleed voltage of off it, while I believe I did PCM -> MAF. That ain't going to work!

I'll upload pics of the completed job and results when life gives me the chance... The car is still averaging 50-51 mpg even without LB

Man, things are getting slow around here! I miss getting e-mails from all my subscribed threads Anyhow, here is a quick update on my project!

I am still dragging my feet when it comes to getting lean burn working! Since I am off work tomorrow for Labor Day, it would be an excellent opportunity to trace wires and re-solder connections. I am constantly dreaming of having instant mpg readouts in the 80's while cruising, and this will be my motivation! I must... be... focused!

I got a new license plate!




Amazing how it fits the car, even though the letters are blue

Here are some pictures of more notable trips I have had the past week:




The top trips was from tonight. It was a roughly 10 mile drive through 2 towns from a Sheetz to my house. I caught 2 stoplights, but was able to take advantage of having open roads with zero traffic to trip lights and get in my way (or for me to be in their way?)

The bottom picture is a very familiar route from the local McDonald's to my house, which is just under 4 miles. This might not seem impressive, however I usually average in the 60's to MAYBE low 70's on a good day. Needless to say that this is big improvement! It is worth mentioning that I had to stop at a stop sign on this route too.

That is 148.4% and 247.6% over my car's EPA combined mpg respectively Just goes to show you that you should not let your car's supposed setbacks (Auto transmission, high mileage, non-LRR tires, etc.) hinder you from giving it your all each time you go out on the road!

My tank is at 53.0 mpg right this moment, which will be my best ever if I can hold it steady and keep knocking down the consistent trips I have.

You have a update???

Very nice results!!!

I Love your comment about not letting poor FE manufacturing items getting in your way. You just have to work with what you have and concentrate on the improvements you can make to offset those poor items.

OK now go get your lean burn up and running

I figured out what was wrong with getting lean burn to work today! I am bleeding voltage going from the PCM to the MAF. Since the computer is still seeing the usual voltage, nothing is happening. It needs to be the other way around. This will tell the computer there is less air going into the engine and cut the fuel down, effectively leaning out my AFRs. Only thing is that I can only remain in LB mode for 3-6 minutes at a time before the PCM catches on. A quick coast/DFCO period and I get a few more minutes in

It will be like an Insight with manual NOX purge cycles

The only thing that stopped me today was my solder gun has gone missing Hopefully I can find it sometime this week and get this thing working! I know I am keeping my fans in suspense

Number 1 Fan waiting.lol

[Tygen1]

Number 2 fan is waiting also, get it done!

[BabyDiesel]

It took long enough, but I finally have LEAN BURN!

Preliminary testing shows an increase in instant mpg of 40-55%!

This also happened


This is over 36.4 miles of country, secondary roads and Interstate, traveling between 40-50 mph. Instant readouts were anywhere between 65-85 mpg!

Congratulations!!!

I just went back through all your post from the beginning, its cool to see the progress.

Now the fun begins in how to re-learn how to drive with lean burn.lol I remember back with my first lean burn Honda when I first got it running in lean burn I was driving everywhere just to collect data. Plus its very strange how the brain works when driving for eco or racing on a road course you are learning things you can't even explain to others based on there's not a language for it.

Its mentally exhausting in the beginning, then you adjust to it and it becomes second nature.
