Anyone out there ever experiance engine light issues. Since upgrades my enigne light comes on about every 500 to 800 miles. My tuner DTC's indicates a lean condition and has been reset and checked by my upgrade supplier for whom i have confident in. He states its the gas the hi content of Ethanol in gas making the tuner setting above the set point of 93 octane. I recencly located a gas station that sells 93 octane gas without Ethanol content and will see if this problem persists.
thx. |
I wouldn't blame it on the fuel. Sounds like a tune issue that needs to be corrected. Lean is not good.

Are you using a tune from one of the major retailers like bama or is it a custom dyno tune? Ethanol in the gas shouldn't cause a lean condition. |
Type SCT Custom Tuner, he states the ethanol content shows a highter octane level as times, I am tempted to go back to the stock tune and air box.

When I first installed my CAI before I was tuned I got a lean code a couple times because the engine was getting more air than the computer was accounting for. After getting a tune that took my intake into account I've never had a problem. The gas here has ethanol in it too.... Perhaps it would be helpful to list the mods on your car. |
