Help for fg2 calibration needed!

That's awesome, thank you. I'll get a data log for it after work. Do you know why MAF is acting weird?

[EFICU]

Sounds good. Honestly I don't. Yours is the first one that I have seen that didn't respond to changes to the MAF scale. Usually it's very responsive to scaling adjustments. If I would have to guess, first thing would be cleaning it. Make sure you only use MAF sensor cleaner, nothing else! It might be dirty, or may be gummed up from filter oil if it had/has an aftermarket filter. Or it could be a failing MAF sensor. Either way though, at this point with how it's tuned now, the MAF sensor is only acting as an intake temp sensor. We are using it for any fuel control, so it won't cause an issue on your car. If you do decide to clean or replace the MAF sensor, let me know so I can check for any changes in the datalogs. If you do replace it, please replace it with an OEM unit. I don't like aftermarket sensors controlling fuel on cars. I like to have OEM sensors are high quality aftermarket units controlling the most important parts of the calibrations. In this world of eBay and Amazon stuff, these sketchy aftermarket parts are causing a lot of issues.

Either way though, it looks really good now. So at least we were able to get things inline. We're on the right path now.

Yeah I'm not too concerned about it. Once I get a Hybrid Racing intake I won't even be using my MAF. I just find it strange because my car is fairly low mileage and I thought it was well maintained. Either way it's not a big deal, thank you!

Yeah I wish I had more experience with the issue. The second calibration I sent you I pulled say 5% fuel in the area it wanted that. Then you made the next datalog, it wanted the same 5% removed. That's when I thought something was up. On the next datalog, it was sort of the same demand. So I decided to change it to speed density where I can control the fuel differently and it cleaned right up. 5% isn't an issue anyways, but when it wouldn't respond I began to doubt the validity of the reading and didn't think it was right to leave it that way. Now the fuel trims are great though.

Here's my newest datalog!

Part throttle stuff looks great. I made a couple WOT adjustments. We're just about there, just nitpicking at this point.

Here you go!

[EFICU]

Looks really good. Go ahead and make another datalog with that one when you can. We had a couple knock, but I think it was more of a fluke. If it does it again in this next one I will address it. It looks solid though.

[ryanthom209]

Here's my datalog, sorry for such a long response. I've had a very busy week. My car feels great though!

[EFICU]

Looks really good, the knock sort of stuck around so I made some adjustments. Take this one for a spin when you can, no rush at all. Really just splitting hairs now to get rid of the knock.

[ryanthom209]

Here it is.

[EFICU]

Looks really solid all over, and no knock. We might be there. Just like that one, take it for another spin. If it stays as consistent we might be there.

[ryanthom209]

Here it is! Sorry again for the long wait.
