  1. 2006-2012 Eclipse (General 4G)
    So yeah I'd been tuning on a mixture for forever and finally made the full switch to e85. I saved $12 just on the first tank! It has better drivability, more torque, more HP, not that bad mileage (adjusting my driving has more than made up for the loss and actually gained 1mpg over when I was on...
  2. Part Reviews/Opinions
    Hey folks, A few days I got my 4g GT MT reflashed by Stayer! Overall, for $300, it is well worth the price. The amount of VALUE you get for $300 is awesome. Keep in mind that $300 does NOT include the cost for a tactrix cable ($169+shipping)...or a laptop if you don't have one. But even with...
  3. Problem Reports
    I've been browsing the forums for the code P0421 and it seems many people have this issue. I have read Desert Rat's post about this problem on the constantly asked questions but this is for when the SES light is on, and mine is gone. In addition to this, I have also recieved P0174 and P0171 but...

    Good evening, Love(d) my 2011 6 cylinder sport Eclipse... Last week my battery totally died while I was out of town. I came home, jumped the battery and put article charger on battery. I put a new battery in it too...but no change to the following problems. The car now runs rough, stutters...

    2.4L MPG: Up to 20 city / 28 highway I am getting 18-19 consistently with my MPG app. I do a lot of city driving and when I drive the interstate its for about 20 miles and I am running 80MPH so the RPMs are a little high. Do you think the interstate RPMs are killing my MPG? I dont redline...

    Ive read on here about the reflashes, and understand some about them however Im kinda limited in what I know of the eclipse. Im looking to spend roughly $100 to tune for such things If its possible I would like to know how. I understand pretty good once looking at maps and things just would like...
  7. 2006-2012 Eclipse (General 4G)
    I didn't know what to label the title for it to be accurate, Is there a tool (maybe even the OBD2 reader?) i can use to plug into my ECU and find my MPG?
  8. 2006-2012 Eclipse (General 4G)
    My cousin wrecked his 06 GT a few days ago, i own the same year GS. He said i could have anything off it i wanted. What all can we swap to the GS besides tb, fog lights, and TC? Like would putting the GT injectors in my GS do anything other than make my MPG drop?
  9. Automotive News
    According to several sources, Nissan is in talks of purchasing a controlling interest in Mitsubishi Motors, who most know are in the midst of the MPG scandal. It hasn't been confirmed, but it is seeming pretty likely. What are your thoughts/ideas/wishes/etc. regarding this? I, for one, think...

    Mitsubishi Motors CEO, COO likely to resign over mileage scandal: papers | Reuters I actually see this is a blessing in disguise. The scandal itself is hardly as damning as VW's, and even Hyundai's a few years ago. But a new CEO? I'll take that. I'm good with them pursuing more environmentally...

    Birthplace of the Eclipse closing, Mitsubishi production leaving the US Rather than releasing a 300HP/30 MPG/RWD bitchen' 2017 Eclipse and Galant, Mitsubishi is closing their sole US plant in Normal, IL. This is where all Eclipses were made, currently where all Outlander Sporties are built...
  12. 4G Eclipse GT/SE Specific
    Hello, everyone I have a 2007 Mitsubishi Galant Ralliart and I'm looking to buy headers. I've been riding with the CEL on for months due to O2 sensor in the rear, I did the spark plug fouler mod and it worked for about a week before the CEL came back on. My city MPG has decreased and I've...
  13. 2006-2012 Eclipse (General 4G)
    I have noticed a pattern on these and other forums. People think a CAI or new filter will improve MPG. This is false and to confirm it myself I read a very extensive case study I will have to link later (its nearly 6am and Ive had some wine) Your ECU will regulate the gasoline sent to the...
  14. 2006-2012 Eclipse (General 4G)
    Hello, I recently started making application (dashboard computer) for my 4g. My goal is to make a nice looking program which will display and calculate: - Fuel consumption L/100 km / MPG TRIMMING PROBLEM - Fuel remaining DONE - Distance to next fueling NOT STARTED - Engine Temperature Celsius /...
  15. Tuning and Electronics
    I've been chasing slightly poor mpg and the power is off from where I think it should be. I've dobe a few tanks of cleaner and sea foam. Checked plugs, which looked great but I replaced anyway,* vacume leaks and all the basics. Car - v6, SRI, Open exhaust, gutted stock exhaust manifolds,*...

    What app(s) do you all use on your phones for diagnostics/monitoring stuff (mpg,rpm,etc...), and anything else that would have useful info from the car. I'm looking at getting an after market radio that will display all this stuff from my phone to the radio display (if possible). Just looking...

    Does this forum have anything like what's in the Evo thread below? Evo X ECUFlash ROMs - EvoXForums.com - Mitsubishi Lancer Evolution X Forums Just a small list of ROMs depending on your modifications. I'm not looking to make this thing a race car by any means, but I'd like a few more ponies...

    As this process is moving forward it is looking beyond encouraging. Due to the free software not being ready the process is somewhat slow but this is a good thing for now. There are a few test cars out there and it appears it is going very well. Here is a quote from one of the test cars. Here...
