Well I think I deleted my comment by accident. Thanks for the replies. I definitely don?t rely on narrowbands for anything. I was just wondering if they could be used to check the widebands...

I have a wideband, im just trying to compare what it reads to what the narrowband voltage reads and do a check. Ive had logs where my wideband is down to 10.5 and o2 voltage is around 950 mv. Im just...

I was wondering if you could rely on the narrowband voltage to tell you roughly how rich/lean you are? I know narrowbands can only tell you if youre lean or rich but not exactly by how much. But if...

Sorry for the late reply, been swamped at work and the weather hasnt been to kind either. But yes I did your method while just driving normally as well but that particular day had heavy traffic and...

Hondaeater I think you were confusing me with HQforme.

Sorry for the late response, been busy with other stuff and havent had much time to work on my car. So I figured my VE was riddled with bad...

Hmm interesting. Was that log created on a dyno? Because it sure looks like it. I?ve tried that method but it requires me to hold the brakes. I can never do it long enough to get an entire rpm column...

Heres a few logs of between 10-15% constant TPS. It does seem to get better but I still have that problem where my AFRs go super lean. You can see it some in the "LQ9 4.5.4 log" around time stamp...

Ah I see what you mean. I?ll leave the bias table alone then and focus on the after start enrichment. I had to run to the store for some stuff and took the car. Seemed to drive well in CL though I...

I did redo the RAF this morning after the new TPS. I disabled the fans and removed the LTIT from storing any values. It idles pretty well now and significantly better than with the old TPS. Might...

Thanks for the reply. I had always read that you just drive normal when dialing in the VE on the street. And at the time I would realize there were certain spots in the VE you don?t hit normally. My...

Might have included the wrong file, im not sure. Im starting to think I exhibit traits of dyslexia sometimes. I have a bunch of logs and I always forget to save them so I end up having to hunt...

Well I figured out theO2 sensors. Apparently the previous owner must have switched the front and rear o2 plug wires at the ecu. I plugged in the front o2s to the rear o2 plugs and now I can go into...

Well I finally figured it out. Turns out the previous owner DID swap the front and rear o2 sensors at the ecu. So front plugs report as rear and rear plugs report as fronts. After chasing fuses and...

Ruebone: Having a tps above .30v for my setup will decay IAC counts to 0 faster than a rabbit gets, well you know lol my method of determining tps voltage is to get it up to operating temp and then...

Turns out the muffled sound was a product of having the PID airflow controls too high. I halved proportional and integral and took 20% off of derivative. I also reduced the time between corrections...

For some reason its not letting me upload video. Says the .mov file is invalid. I also tried .mp4 and it still gives me the same issue.

So did a log this morning of a cold start and my iac counts were up in the 200s again. I waited for them to come down but at operating temp it only went as far down as 140. Yesterday I made sure that...

I replaced both header gaskets and doubled them up with GM steel gaskets. Both sides had one blown header pipe for sure and a couple others but less severe. Hopefully they dont leak again because...

Heres a log at 18 degrees idle timing. Seems like everything is working correctly but the exhaust sounds muffled almost as if it were under water or something. I can record a sound clip and upload it...

1.) Terrible lean condition when I start it up regardless of temp. Sometimes it starts where it should at 14.7 but after a few seconds it goes up to 19+. Sometimes it just goes straight to 20:1 and...

Honestly don?t know what to do anymore for idle tuning. I?ve tried reading a few guides but I seem to get nowhere. It?s very frustrating and discouraging. I may as well start over with a brand new...

I changed my idle spark to 24 and made the over/under adaptive spark to be more aggressive. I realized that I was not very aggressive at all in combating idle rpm. I also lowered the PID update error...

My inability to understand is not your fault. The issue was my misunderstanding of how the VE table works. I was under the impression that those numbers were fuel numbers. Because if you make them...

I don?t know for a fact I was just told based on my logs. I don?t know a lot about tuning and I definitely don?t know how a lot of the ECU functions work. Deatschwerks said the data was copied over...

I was wondering why my cold starts were down around 5 degrees advance instead of 18 like it should. I didn?t know that catalyst spark correction and EGR spark tables had that affect. I made the...
