VERY high AFR's and erratic TPS

[MarkyMark203]

92 Civic
12.5:1 JBRE 88x99 K24/K20
Xcessive centerfeed
Q45 tb and TPS
New OEM o2 sensor

Im seeing mid 20's:1 air fuels. I even tried scaling the injectors and adding 10% overall fuel trim and nothing seemed to get it to go down. Car is up-idling on its own.

Heres the log...

SPUNK? HONDATA?

You have not posted a calibration to look at.

I will first thing in the am. Unless you have an email I can send it now

Your TPS does not appear to be reading correctly as you have it adjusted with very high numbers and I never see it really sit at 0 in the datalog form more than a split second 2 or 3 times.

Your O2 sensor does not appear to be reading correctly as well as it is just fluctuating back and forth but never holding a stable AF.

I would suspect a vacuum leak of some kind and also either a faulty or poorly adjusted TPS.

Ok, so you don't think the primary o2 is wired incorrectly? I also suspected a vacuum leak but don't find any. I thought the Q45 tps was just hard to calibrate. but the whole time im logging its idling, im not touching the gas at all

I don't know what the problem is as it sounds like there are multiple problems at the same time.

I'm more concerned about the VERY high AFR right now I mean realistically a motor cannot run at that ratio. What gives?

Start by fixing the other known issues.

Fixed the TPS last night with a new one. Still experiencing the 25ish:1 air fuels.

[MarkyMark203]

Anyone know what could be causing this?

[MarkyMark203]

I got high af when I had a split fuel pump pipe... Don't know if that's your issue just another possibility

Can you elaborate?

[MarkyMark203]

I changed my pump to an aem 320lph pump I used wrong pipe first time and the pressure must of balloned the pipe to cause a split (no sitching to straight rubber pipe) the pump would prime and the car would start and it was fine for pottering round town but under load the car had much less power and my gauge was hitting 18s aem don't read to 20s I never needed to check a datalog, but the car never splutterd or skipped a beat just high af.... I'm not saying that your is pipe is split just maybe a fueling issue somewhere

I managed to fix the TPS issue by getting a new one today..

But now i am still experiencing this bogging when i blip the throttle. not so much when i slightly get into it.. heres a log.

Is there anything i can physically check for fueling issues?

[MarkyMark203]

Are you still getting high afr? I can't check the log as I'm using phone.... I only knew my fault as it only happened after I changed pump.... Could be so many things

Tuned the car last night. No problems. Air fuel was fine on his innovate lm2. So the abnormally high air fuels HAVE to be a wiring issue. Just don't know what.
