Hello Everyone,
I need some help from you to analyze & tune my car.
I have attached a PL file from last night to review.
In the two WOT blasts I see some things that have me confused.
I see my MAF is under 255. Is this common at a lower level of boost like the 15 lbs I am running? I thought the TT chip locked the MAF at 255?
The wideband reads lean; about 12.8 – 13! The lowest I can find is 11.77. Looking at the BLM table I see that WOT A/F ratio is set to 10.8 but the correction factor BLM reading is 128. This means that the chip is not doing any correction right? Why isn’t the chip adding fuel to try and achieve 10.8 A/F ratio? The injector duty cycle is not too high.
Should I go ahead and add WOT fuel with the chip to try and richen the A/F ratio up?
Is the lower MAF reading not commanding enough fuel?
Don’t get me wrong. The car pulls strong and is fun to drive! :smile: Right now I am not comfortable raising the boost until I get this figured out.
Please take a look and let me know what you think. TIA
