My secondary air system is saying not ready, which it is connected and the tune is the EXACT hypertech tune, except the PE table and the spark table.
Air pump on time is 190 and all the other settings are default(stock)

ALSO the oxygen sensor heater says not ready. I deleted my rear O2's (put sims on them, and then ended up putting them to not reported)
I do not know if the heater means the front oxygen sensors, or the rear. I THINK the front. But why wouldn't they be ready???


I have a wideband hooked up and I'm reading excellent AFR across the board(~14.6 at idle and part throttle) and the car has been driven around 225+miles. Several of the 'not ready' items have become ready...do i need more driving?

[ZL1Killa]

......maybe??

[Black02SS]

Email me your tune and I'll take a look at it for you.

[ZL1Killa]

can 01 cars run without the MAF and not have the DTC codes shown in efi live or when testing for inspection

[ZL1Killa]

I THINK I FIGURED OUT THE PROBLEM.

THE secondary air pump runs with the 02 heaters when the AIR PUMP runs and it performs a test by seeing the changing voltage(i think)

HAS ANYONE GOTTEN AWAY WITH PASSING INSPECTION with the AIR PUMP REMOVED

[ZL1Killa]

and as my car is a 2001 it can only have 1 not ready code

[BowlingSS]

and as my car is a 2001 it can only have 1 not ready code

I setup a special tune that shows everything ready and no codes. Did not need a driving cycle. I just stopped before the inspection and downloaded this tune , passed no problem. IT WAS JUST SETTING UP THE DIAG CODES TO SHOW ALL READY. I do not have AIR, MAF,CATS or O2's.

now when i turned off my maf codes (to NOT REPORTED) the car didn't want to run??

Now, when i did turn the MAF codes to not reported the MAF was OFF of the car. Then I programmed the tune in and cranked the car and then it
idled funny and then cut off.


or does switching all those codes off that you sent me, Bill allow for the car to run? I saw the 02s(open loop of course), the MAF, AIR,...etc





Right now I'm going to run as is to get inspected and pass, as the AIR crap is back on.

Me and my friend are going to dial in the MAF, AFTER INSPECTION and turn off the air pump completely, so that it will never come on and cause bad readings on the wideband during dial in.
Nick Williams is running the MAF and I'm curious as to how my car will perform with it calibrated correctly, as my past dyno numbers were my best with the MAF....however if it doesn't go good, I will DEF. go Open Loop...as before the car was running fine

[ZL1Killa]

how do you get the car to run without the MAF, (the DTCs set to not reported)?? my car didn't want to run after simply cutting these off

[ZL1Killa]

someone.....anyone....

or do you just cut all the MAF DTC's off and its supposed to work?

[joecar]

The MAF DTC's trigger the PCM to failover into SD;
without these DTC's, SD won't happen (I don't know what airlfow values get used).

[ZL1Killa]

so how in the hell is BowlingSS running with his codes off...... to not reported.

I understand what you said, as that is what i was told, and I know.

[ZL1Killa]

I'm being left in the dark somewhere....WTF is going on here...is it a custom os on BowlingSS 2001 camaro??
........

maybe...kinda...anyone know?

[joecar]

From what I remember, I do believe that Bill is running COS3.

[ZL1Killa]

COS3; So if i go ahead and go custom OS, then i can run without thost dern DTCs....at least i'm assuming

[joecar]

I haven't been doing COS's... yet...

It would be best if you talked to Bill (BowlingSS) and Andrew (Tordne) since they have been running COS's.

[DrX]

I have been wondering the same thing. I have COS3 and it won't run without the MAF if the DTCs are set to "Not Reported".

Yes I am running COS3. :exactly: My car ran fine with the MAF set to X but only set them to X for the inspection. They are also set to No MIL. I only drove it a couple of blocks that way. They are set to C: Non Emissions now.

I can't find your email anymore. I just thought of something and want to double check it. Can you reemail me your file?

Thanks Bill, but I was talking about ZL1's tune. LOL

[BowlingSS]

Thanks Bill, but I was talking about ZL1's tune. LOL

Sorry about that.

Bill

[Black02SS]

I don't think a custom os has anything to do with it personally.

[Black02SS]

Sorry about that.

Bill

No worries. It actually might help this situtation.

[BowlingSS]

I don't think a custom os has anything to do with it personally.

I also do not think the COS has anything to do with it but could be wrong.:exactly:

hahahha....that was good guys.. I'll get it out to ya right now chad

Just got it and sent you a new one back. I need to have a tune where the VE table is dialed in with the maf disabled/unplugged. If you use the tune I sent you, watch your AFR at idle and make sure it doesn't go lean. If it does, add that amount to your ve table just to get it in line for now to see if it passes the tests.

[ZL1Killa]

gotcha...yeh i haven't gotten around to actually tuning the car yet as I have had school and got the car inspected yesterday(passed) and once I get down to flashing it I will be going over everything to make sure it will be ok going OL

I am going to say the reason your car didn't run right was when you removed the MAF and set the codes to no reported, it wouldn't let the car fail into SD and was still looking the MAF table, causing the car to run so lean it wouldn't stay runing. That is my theory and I can check it out on my car tomorrow for you as well.

[ZL1Killa]

I really appreciate the help. Thursday I will be dialing in the MAF....with that all you have to do is disable LTFT and set the closed loop temp to a high temp....(then have your VE dialied in before hand)..then drive around and log the MAF, correct?

[ZL1Killa]

I had to tune my friends 98 and I turned off the EVAP, AIR, EGR, 02 heater performance..etc like shown in BowlingSS tune he sent me(and chads) and the 98 still had the 2 not ready tests for AIR pump, and 02 heater

?? Does Paul or Ross know anything about these ready tests?

any way to get around these codes and have them read ready...obviously it has to be due to the custom OS

I did not have any ready problems with the COS 3. I removed my AIR a couple years ago.

[ZL1Killa]

you say COS 3; does that mean operating system 3? I have not gone COS yet but I'm at this rate VERY interested...and I know tordne already volunteered himself to help me every step of the way.....lol.

anyway what do you mean by COS3? is that the COS from 2003 installed on your car, or what?

I remember seeing on the downloads page
custom_01_cal_20051113 for 2001
custom_02_cal_20051113 for 2002....etc for the rest of them..does that mean you have custom_03 for 2003 model??

EFILive Custom Operating System version numbers contain the following features:
Version
Feature Set
01
• Dual spark map speed density enabled.

02
• Dual spark map speed density enabled.
• Valet option.

03
• Dual spark map speed density enabled.
• Valet option.
• 2 and 3-bar forced induction enabled, but will
still work on 1-bar systems.
• Open-Loop, RPM/MAP based fuel control.
(on selected operating systems)

I am using 03.

[ZL1Killa]

gotcha....i finished looking at it last night and saw that. Right now, I'm taking the COS to be the case where it will let things be ready like they were on your car; as on my friends 98 it says the AIR and Heater are not ready and I turned them to Not Reported

[ZL1Killa]

nevermind...I will play more with these DTCs and what not once I get everything tuned...at least to where i want it

[hpcubed]

I think custom OS 3 should not look for the maf at all ! :grin:

How bout it Ross?

[ZL1Killa]

...custom os here i come...lol
