I'm scanning a friend's car and this car looks like it only has 1 oxygen sensor working. Do you think this FWD car needs 2 oxygen sensors working? I would think so. Anything else wrong with this? ...

I didnt install the pinion nut to 150 ft/lbs so after a year of driving on my 4.10s they fell apart
It was great! Hey, at least I know how to put gears/posi in and rebuild my engine!
I bet I...

Will plug it back up

What is all this data I have in my histograms (1 & 2) Each time I log then?
Is that a v8 thing? It Seems to be working... BUT

If you were to tell me "it looks like its working but actually will...

yes, that has Always been the best option
or new car

Here is another deal:
it always seems that I get KR when (LTFTs & STFTs are -negative = rich) . also (low rpm). also (o2s at a high mV = rich) ...low timing

It just seems like I shouldnt be...

You said I was too rich
Plz check out these LTFTs and KR tables
Why am I getting KR if I'm too rich? :crazy: :banghead:
DFCO IS OFF
thanks

mine dies alot
it can reach 400 rpms (or less) and stay running LOL
Its like its searching (surging) for good AFR
I've turned DFCO off
Once I get in the very low rpm range, I have to watch rpms...

I've been having this same problem since I do know when
Upped the Idle Rpms a little... didnt fix it

nice post

f0ff667 is right
You are just telling the ecm to not turn on the SES light when the maf fails.
In your case the maf is still working fine
You should set the "maf fail hz to 0" or just unplug
I...

it would seem that way
but if I lean the VE table out by -1 or -2 points on the VE table
it will get KR in that area

o2s show lean most of the time (under 900 mVs)

I cant get LTFTs into the...

Is .17 or .18 soon to have a release date?
Probably wont benefit from it... but its cool to see a fine product improve

how can I have such KR at 500 rpms and -23.4 LTFTs? lol
917 and 892 o2s (I know its slightly lean)

1) Upon my rebuild... I broke the plastic on my cam interrupt.
So I made my own and it set off a DTC
Recently I put in a real, new cam interrupt and the dtc is still there.
I've tried doing...

When the MAF is NOT plugged in..
does the ECM disregard the LTFT #s?

I've started working on my VE again
and it really seems I have gotten it alot closer and better than from when it was
messed...

why do you prefer one side over both sides? 2 > 1 ?
thanks

:crazy:
interesting! thanks!

In OL (just started the car) my Real AFR is perfect 14.7!
but once I get in CL the NBs make my Real AFR jump around (normal)
Thanks guys

I'm sorry what do you mean by injector error?
Are you saying my injectors are not setup right? (hope so)

The thing I was trying to say is that in the description it says the injectors are:
...

It does this for my tune file and for my friend's.
Its obviously my HPT editor though

No biggie

guess the description is just backwards

Does this really say the MAX LB/hr I can have is 7.9 ?
We're trying to get it tuned for 65 lb/hr
60 lb/hr static (630cc) mototron from zzp.
thanks

I never had that one, but thats just me
