Default System Lean after header install

Hi guys, I am having trouble with my '00 SS Camaro. It has BBK Header system(with their Y-pipe), Corvette O2 sensors, K&N FPIK air intake, and am running E85(just changed the stoich). I haven't figured out how to tune the MAF because the method I was going to use couldn't be used with the Beta version of HP Tuners(I had found this method on the HP tuners forum). After installing the headers today, I got a P0171 code, and also noticed that my intake temps got in upwards of +100*F! ISn't E85 suppose to cool things down? Can anybody offer any advice? I have the HP Tuners software, and have asked this same question over on their forum, but nobody wants to offer any advice.

I tried to upload my scan and tune here, but wasn't able to do so, so here is the link to my thread on the HP Tuners web site:

Yes of course it will change the way things read. And yes it is very common for it to read lean after headers. I have been using HPT since the day it came out and yes you can tune the MAF on this car with ANY version<beta or not, of HP Tuners. PM me if you need some help. BTW E85 doesnt run thru the intake as a LS1 is a port fuel injected engine so it will not cool down in coming air.

The KIPK has been referred to as the "Hot air intake" Only make good numbers on a dyno when the hood is up.

The E85 has nothing to do with your 100+ degree intake temps.

Is the FPIK the kit where the filter element is open under the hood?

Yup, that's the one. It came with the car when I bought it. I'm going to cut an opening on the bottom plate, where air is suppose to come in through. K&N really messed up on this one.

^ I've had K&N intakes on two different vehicles... Haven't been a fan. The forums for my DD don't advise them either.

Here are the scan logs, and the current tune as well, with the green top injectors.

B1 S1 looks like crap. really no response, how many miles, what is the installation like on that one? is it plugged it all the way? etc, check for insertion length into the exhaust, check connections, etc.

Did you have a wideband reading on that? I didn't see it in the log or what loaded when I opened the log file. how can you say lean if no wideband? Were the corvette 02s used? I suggest swap the 02s and see if the problem moves or stays on the same side. if it stays on the same side, then it is an installation/insertion issue. If it moves , then its the 02 sensor.

as far as the intake temps...well get it some fresh air and go driving, stop sitting still.

Everything is set all wrong to start tuning but as the above poster said, the B1 O2 is either very lean or dead. You have an exhaust leak, open headers with no extension off of the header or a completely dead O2. If you check these out I can help you out.

Unless you're going to be pouring fresh fuel through your intake tract, I'm gonna go on a limb here and say that E85 is not going to have any effect on your intake temps.

I finally got time to swap out the O2 for one of the stock ones that I modified. The new sensor that I put on was bad and now it is working properly with the modded Denso O2. It still lean, as it needs 30% more fuel with E85, but no more rough idle, or bank 1 lean code/random misfire. I don't have a wideband hooked up, and the HPT I have is the standard version, so there is no provision to add the wideband. I will take it out tomorrow with the scanner hooked up, and post a new scan log.

I didn't look at the logs, but why wouldn't you have a P0174 as well?
Seems like a bank 1 specific problem vs. being a tuning concern that would affect both banks equally.

Not sure, butas soon as I installed the modefied stock O2 sensor the problem went away. Now I'm just waiting to get the exhaust welded behind the Y-pipe where it meets the back pipe to get a more accurate scan log.
