  1. 2006-2012 Eclipse (General 4G)
    So in my area premium is 93 octane, mid grade is 89. What do you guys think about mixing 93 and 89 octane in order to reach 91 octane.
  2. 2006-2012 Eclipse (General 4G)
    Hey guys, I was wondering about how well the 4cylinders would put up with mixing some E85 in the gas tank I know this is commonly done on Subaru WRX's because they require premium, so you GT Eclipse guys might be interested because of this. What people do for the WRX's is either mix E85 about...

    Hi Guys, So I was driving through basically a hurricane yesterday is my 07 GS with a DC Sports CAI. It's relatively well shielded I thought (Filter behind the fog light) and I do have that AEM "Hydroguard" prefilter sock on it. That being said, I was on the highway (traffic moving about 60...

    After posting on reddit about my dyno I got a lot of hate for 4G and 4 cylinder, but a few good souls said to just keep working on the car and run 1/4s to get a baseline, so I decided to hit the local 1320, its gonna be a street car night so I shouldn't be the only piece of rice out there. I'm...

    I am seeing the "fuel economy tune" is this for WOT or 1/2 OT AF ratios also how does retarding the timing make more compression, or can it. and last, whats the REAL power increase on a 2008 GS with ECU mod/flash. I had a diablo sport inTune for my food and it had a 93 octane race tune...

    OK, I KNOW there are tons of threads from people who want to know if they can put regular gas in their GT. And I KNOW there are always a few people who are quick to tell someone that they must be dumb as a stump to think they must save a few bucks by using regular. And I KNOW some folks feel the...

    title reads my question. has anyone ever tuned for 87 octane? gas is quite expensive around here... about 1.45 a litre so just over $5 a gallon. i do quite a bit of city driving so im trying to save a bit of money by doing an 87 octane tune.

  11. 2006-2012 Eclipse (General 4G)
    can anyone give me a bit better understanding of high vs low compression pistons. i know that high compression is used more in N/a cars with high octane ratings. and lowering the compression ratio is a good idea if your F/I so essentially im wondering what the benefits of increasing the...

  20. 4G Eclipse GS/SE Specific
    I've had my Eclipse for about a year now and about 3 months ago it started shaking really bad around 55-70mph. I have had the plugs and plug wires replaced, and 2 new sets of tires. I've tried switching to higher octane gas to see if it was just a knock, not it. It will shake while idling as...
