Help for fg2 calibration needed!

[ryanthom209]

Hello all,
I've been running my fg2 civic(only 2.5in catback) on the stock tuned basemap for about a week now and I decided I should probably make it fit more for my car. I am a total newbie when it comes to tuning, and I've heard some people have had success with autotuning so I decided to give it a shot. Well it starts to run SUPER lean above 6000rpm, to the point where it is probably dangerous. If anyone can help, either by telling me how I can fix this or providing me with a safe basemap it would be greatly appreciated. It seemed like it ran much better before I did autotune, and the only way I can think that happened was because I switched the calibration to speed/density. I will attach my recent calibration and datalog. Thank you guys!

Hey Ryan,

Definitely don't do anymore wide open throttle (WOT) pulls until you have someone look at this. It's way too lean on the WOT pulls. It needs work all over, but that is the main concern.

If you want some help with it let me know.

Thanks you for replying, I hope I haven't caused too much harm to my car. I've been driving very conservatively and only done WOT for the datalogs. If you could help me solve this problem in any way I would be very thankful. I haven't gone to a tuner because I'm planning on getting a Hybrid Racing Intake and header soon, and I don't want to spend $200 only to spend another $200 a month later if I don't have to. I've since switched to a different basemap, but as you can tell I need more than a basemap. Once again, any help would be greatly appreciated and I will even compensate you for your time if needed. Thanks again!

I'm pretty sure you're okay, I just wouldn't recommend going out and beating on it is all. It takes a lot of prolonged stress to cause a problem, I just just wanted to make sure you weren't out beating on it is all.

Since you plan to add more mods, I would recommend to put you on a completed file so it's safe and you can have fun with it while you await more mods. Then once you get those mods, I can help you tune it or you can get it tune from someone else if you'd like. With the completed file, you'd still make a few datalogs over a few revisions to get it dialed for you and safe.

So the only mods is the catback? Stock intake and cat pipe?

[ryanthom209]

Yep, the only thing done to it is a 2.5 in catback. I was driving it like a grandma so I think it'll be fine. Thank you once again for the help, I dont have much money at the moment but I am more than happy to provide compensation for your time if you would like.

Okay give this one a drive when you can. Shoot for 20 minutes in length and throw in one third gear WOT pull from 2500-8600 so we can see the WOT fuel stuff.

This already feels much better, thanks!

[EFICU]

Yeah it looks pretty good Ryan. However, it does look like your primary o2 sensor is failing. When it does this, it can't provide a proper reading for WOT fuel. I compared it to your previous datalogs, so you were definitely lean before and now with more fuel it's still showing lean, but nowhere near as bad, and I think it's the sensor failing at this point. I put together a test file with the name DONOTUSE, I don't want someone else using it, but you can. I basically added more fuel, so take this one for a spin and all we really need is a third gear pull so I can compare the fuel data. This will tell us if the sensor has failed or not.

Here's the datalog, I wasn't able to get a complete WOT pull the first time but I did another one so hopefully it works.

[EFICU]

Yep, the primary o2 sensor has failed. We will need a new sensor before we can move forward on it. I recommend these three options to replace it. All of them have worked well. I would recommend avoiding any Amazon or eBay ones if possible. You mentioned before you don't have a lot of disposable income, so please take any money you thought about sending me and put it into a good sensor. I wasn't going to take your money anyways, but now I really don't want your money. So please grab one of these, but if you have to get something cheaper we will try to work with what we can.

--Honda OEM 36531-RRA-013: https://parts.hondaofelcajon.com/oem-pa ... 4PEALw_wcB

For now, please go back to our previous revision, Rev01, and run that until you can get a new sensor. I would avoid any wild driving, but if you need to get on it to get out of the way or something you can. So don't feel like you have to tip toe around, you can go WOT if you need to avoid a situation. Just don't do any canyon runs or unnecessary aggressive driving. The sensor works fine at part throttle by the way, so you can drive it without issue for work or school.

Keep me in the loop on it all.

[ryanthom209]

Once again thanks for the help man, means a lot. I will fix this as soon as possible (hopefully in the next couple days.) Until then, I will be sure to be gentle on it lol and will keep you updated. I don't have a lot of money but I don't like cutting corners if I can avoid it, so don't worry about me using a cheap o2 sensor.

[EFICU]

If you are in the 209 area, there are a lot of auto wrecking yards in the area who can probably snag a used one for fairly cheap. Just make sure you compare part numbers and all that. Either way, just let me know and keep me in the loop.

You're welcome!

[ryanthom209]

Hey just a quick update, I got the sensor installed and am going to take it for a drive tonight, should I just get a datalog of the first calibration you gave me? Thank you!

[EFICU]

Make a datalog on the calibration you've been driving on, Rev01. That will be our best place to start.

[ryanthom209]

Here's my new datalog. Looks like I installed the sensor properly lol.
