    So I'm kinda figuring out or have been figuring out that the aftermarket support for this car is ki da crap. I was wondering if I got bigger fuel injectors without a turbo or super charger and then get it tuned. Will anything bad happen to my engine like the crank shift. I have a aftermarket...

    2009 Eclipse GS. I was talking with my co worker about my fuel economy or lack of. He suggested changing the fuel injectors. Will this increase my fuel economy and if so could you steer me towards what products to look for. I would have a mechanic handle this job. Thanks

    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...
  11. Forced Induction & Nitrous
    It's been awhile since i've posted but i feel the need to give a quick little list of parts required to build the 4g69 for boost. While you can stay around 10 lbs of boost on stock internals if you wanna go past that here is a list you will need. I did the research and will be building soon as...
  12. Tuning and Electronics
    Does anyone use the 02 Wrx injectors? (420cc) I'm trying to tune them and the current settings that I have from Hackish make it knock like crazy I see 20 knock count for like 15 minutes at times... It's either from the settings forcing it to go lean, or mitsubishis iat adjustments. Any help...
  13. 4G Eclipse GT/SE Specific
    Greetings, I have a 2007 Eclipse Spyder 3.8. It ran fine a few days ago. Today it cranks but has no spark and no pulse to fuel injectors. There is supply voltage at the injectors and ignition coils. There is also a pulse from the crank sensor to the ECU. Any suggestions? Thank you.

    Hi Everyone, I purchased an 08 Eclipse for my teenage son last year. Let's just say he has well lived up to the stereotypes on young male drivers! I have put a small fortune into repairs on this car already. He is moving on to a truck now. Given that I have put a lot more into it than I...

    hey everyone Trying to find out some info. I have a 3.8L from a 2004 Galant. Used to be running using Megasquirt but now I am reverting back to the stock ECU in my 99 Avenger. Does anyone know if the Injectors are high or low impedance? Or if the Avenger is for that matter. Thank you

    sometimes the car wont start. I tested the battery at 12.58 Volts but IDK if I should really test it after it has set all night with no charging. The car cranks but its like the injectors arent spraying ? I turn the car off, turn the key on, count to 5 then turn it over and THEN it will...
