New member 2004 Pontiac Vibe
 
I've been a member for a couple of weeks now, long enough to get my fuel usage data entered to establish a baseline. I've been developing my driving technique since I started buying my own gas some 45 years ago. The best tactic I've found is to plan my trip so I can leave early enough that I don't have to drive fast in order to arrive on time. I live on the plains of west Texas where there aren't a lot of hills and curves, and most roads are straight and the curves are banked. Wind is often a factor, and I allow extra time if i know I'll be facing a headwind so I can drive more slowly.

My car is a 2004 Pontiac Vibe-a Toyota Matrix in Pontiac disguise-with a 1.8 vvt-i engine and automatic transaxle. I bought the car new, have 81000 miles on it now, and haven't had to do any unscheduled maintenance on it yet. Looks like I might have to R&R the front brake pads in another 50000 miles or so. Most of my driving is rural, and I always coast to a stop if practical. The Vibe is tuned for performance, but it will get EPA estimated mileage with some effort. The biggest impediment is the cruise control. The slightest rise in the road while using cruise control will cause torque converter unlock and downshift, so I don't use CC unless I'm driving on a flat road.

I have a scangauge, and I installed a Protium Fuel Optimizer on 10/09/2007, and my gaslog will reflect any changes resulting from it's use. I'm looking forward to learning techniques that work for others and sharing any knowledge I have to help other members on gassavers.org.

Anyone desiring more information about the Vibe can get it at www.genvibe.com.

Welcome to GS! I'm *very* happy to see another Vibe/Matrix here because I want to see how they perform.

Since you've had it 81K miles, how has the seating position felt? We had a neighbor with a Yellow Matrix who traded hers in because she didn't like the seating position. She's a bit tall, so that may have something to do with it.

Welcome to the site, I wish you the best of luck.

Seating position
 
The seating position is one of the things I like most about the car. I'm 6', and it seems that I sit high and have good visibility. I would like for the seats to be harder, but I guess I can't have everything.

Welcome aboard. Quick question: does the Protium Fuel Optimizer hook into the IAT or Map circuit, or is it something else? I'm an electro nerd at heart. :)

teamjdb 10-12-2007 01:47 AM

Bob it hooks into the MAF circuit, giving 3 basic settings: City, Highway, and Performance. The city and hwy settings have variable resistor controls, allowing adjustment. I've only driven about 50 miles since installation, but the scangauge shows quite an improvement in mpg. Time will tell............................

Welcome to the site!

I have an 05 Matrix auto that I use for my job (Maine USPS Rural Carrier) and so far the vehicle has been great. I only have 21k or so miles on it now but am pleased with it.

Great interior room with rear seats folded down. Unfortunately I don't keep track of the mileage on paper because I thought it would e abysmal but every time I do fill up I calculate quickly in my head and it still manages to get low to mid 20s.

Great car name by the way!

went to that Protium web site and i don't understand which one you bought. how does it work?

teamjdb 10-12-2007 05:33 AM

Boofighter, it taps into the MAF circuit and allows regulation of the current from the Mass Airflow Sensor to the ECM, which in effect allows control of the fuel/air mixture. I'm sure they could explain it better at the Protium website, and they are friendly folks, so you shouldn't hesitate to ask them any questions you have. I intend to keep my gaslog updated so everyone can see the results.

Thanks for the info. I used to have a similar device on a Trans Am, and it worked pretty well. Too bad my Cavalier doesn't have a MAF, or I'd prolly try one out. :thumbup:

Bob, the installation instructions say that the optimizer will work on a MAP system and give fair results. Just what "Fair results" means, I don't know, but I'll
bet Steven at Protiumfuelsystems.com could explain. He's a nice guy, and he has enough faith in his products that he put a link on his website to my gaslog.

Here's a similar thread :

protium gas optimizer?

I originally thought it was an EFIE (02 sensor spoofer), but I was wrong.

My Vibe/Matrix is the best car I've ever owned! Great trade off for a Truck, Van and economy of a car! I thought the 1.8 Ltr Engine would be under powered, I was wrong! It has plenty of power and as for seating, it has more room than my '06 Ford Torous. It seats a 5'10" person just fine with plenty of leg/head room to go.

I'd like to see someone run Hydrogen in one. Any takers? Any other Mods? 32-36 MPG is great, but 50-90 would be even better!
