Engine Check Light...OTRCAI

[stukes]

Hey I just had my car serviced @ Kevin Dennis HSV and told them about my engine light coming on.

They threw theses codes at me... P0171, P0175, 26ABS.

Seems that because of my OTRCAI (sureflow) the engine was running rich/lean. He also said that this configuration caused a lot of crap to get into the throttle and injectors and they had to be cleaned....

QUESTIONS:
I still have the MAF on there and want to keep it for added engine protection but will a MAF Tune fix the engine running rich/lean??

Does a OTRCAI (sureflow) really screw the internals because there is more air/crap being pushed into it??

I see many others have OTRCAI and i think it defiantly improves performance, smoothness and fuel. Should i be doing more maintenance on the air filter??

P.S. The 26ABS code appearing is because the module they think is stuffed and that is why my traction control isn't working... $950.... i can do with out TC

Thanks.

You really shouldn't make massive changes to the intake (like changing to an OTR jobbie) without a tune to suit. 99% of those runing an OTRCAI have a tune. Getting a tune will definitely fix up your AFR's to suit the new intake.

Yeah i am pretty set on doing it. I was meant to get it done pretty much straight after i installed it at G&D Performance but i am struggling to find time. Will have to put it high on my list of things to do.

What about the crap they are saying getting into the throttle and injectors... will a tune help this in any way??

if you always run the car with the filter in it i dont see how any crap could get into the motor. Fouled injectors are often caused by many things like shite fuel, not crap in the air???? WTF????. I personally wouldnt pay too much attention to what holden tells you, be guided by the reputable sponsors on this forum

a lot of crap to get in the injectors eh. thats a good excuss to get a clean job done for nothing. even if you ran no filter it is going to make the injectors get crap in them.

if the filter and unit is sealing ok it shouldn't allow dirt in. even with the fully sealed oem airbox the TB gets dirty from the PCV system. although i expect the high flow filter do let more fine dust particles in, however the dirtier they get the better they filter. How well is it sealing when at wot with the motor is pulling to the drivers side, that would cause some stress on it.

Yeah i always make sure it's on. Never driven with it off. I clean it once a month as well.

lol yeah could be a bit dodgy. He also said that a OTRCAI and a tune makes no diff to the car performance....

Agreed.

It sounds to me like the Holden dealer can't explain it and is looking for something to point the finger at. Dirt through the OTR affecting the injectors is total BS.

Code indicating rich & lean most likely indicates something in the tune may need adjusting to compensate. 2 options I'd suggest:

1. Do a PCM reset yourself and see if it rectifies the problem.
2. Get to a workshop that has access to tuning software and ask them to have a look at it ... preferably on of the forum sponsors in your area. :yup:

Before you ask re: PCM reset ...

Basic PCM reset is as follows....


Run car to normal temp. A good 10 to 15 min of driving will do this but if you just idle the car it could take longer.
turn the car off and pop the hood.
open the engine bay fuse box and locate the BCM/PCM fuse. It's normally a 10A "red" fuse.
Using a suitable puller ( as fingers probably won't fit, needle nosed pliers do ) remove the fuse.
turn the ignition to "ON" ( NOT start, just to where the dash comes up and the self check is done ).
Wait for the error message to come up on the dash accompanied by 3 cycles of 3 beeps.
turn the ignition OFF.
replace the fuse.


Now the procedure will differ depending on your mods. If you car has had virtually no tuning work done to the "base idle" ( read no adjustment for a new cam or other mods ) then...


Turn the ignition to "ON" again a pres the throttle to the floor about 5 times. the number has been listed as being from 3 to 5, there is no hurt in doing it more times.
Turn the ignition OFF.
start the car normally and check that it idles OK.


If you have had some idle tuning done, you may need to allow the PCM to relearn the idle settings.

Ensure the car is still up to temp ( unless you had lots of trouble getting the fuse out / in this isn't a problem ).
Start the car and let it idle in neutral for 5 min.
For autos, select "D" and allow idle for another 5min.
Turn off car.
restart car and ensure correct idle.


Thanks Simon.

The dealer mentioned a PCM reset as well. His way of doing it though was to leave the battery disconnected overnight and then connect it up in the morning. Let it idle for 5 mins (it idled real dodgy at first then adjusted). The turn it of and on again and off ya go..... Is this wrong??

Yep this guy really knows his stuff, sh!t in the air filter fouling injectors and a tune + OTRCAI making no difference to performance

:bs:


Time to take your car to a place that actually knows something about cars me thinks :)

Effectively the same but a PCM reset as described above doesn't catch you out if you can't find your radio pin code ... which will need to be reinserted if you disconnect the battery.

PLUS a PCM reset can be done in about 10minutes as opposed to leaving the battery disconnected overnight.

With regards to the fuel injectors, i'd say thats on of the services they refered to as "extra work" where i used to be employed. Basically it was a pointless excercise they'd bullshit the customer into and charge an arm and a leg for...

Stukes, from someone who has run a Sureflo otrcai with maf, yes
dirt can get past the filter if you dont pay particular attention
to the sealing of the unit. I ended up buying extra sticky
foam for the lid as I was getting what I considered too much
shit past the filter and into the T/B. You may also note your
filter will get very dirty in one particular spot, a big round circle
that is suspiciously similar to the size of the maf lol. This has
been commented on in another thread regarding restrictive
otrcai. Go mafless and seal your unit properly and you shouldn't
have any further problems with it.
By the way, I ran the Sureflo item for 2 years with a maf in the
extreme temps of the NT without a tune touchup and did not
have any major drama's. Just be aware that you wont get the
most out of it with the maf in place. Hope this helps :)

Thanks mate awsome response.

I think i wanna keep the MAF as i'm not overly concerned with getting the best possible power. I just want reliability first.... better with the police as well.

I will check mine maybe stuff is getting in around the top of the air filter but i doubt it cause it's pretty tight.

Yeah i get the black circle on my air filter thats why i clean it once a month. Need to get a K&N Filter Cleaning Kit (http://knfilters.com/search/product.aspx?Prod=99-5000) to make sure i clean it properly. Last time i cleaned it i didn't re oil it.

Another thing just sprung to mind (has been a while since I fitted
mine). How did you seal the maf into the bottom of the intake?
This is critical. If you dont seal it properly unmetered air will
get past and trigger your check engine light (had the same
problem myself). I ended up using the same sticky foam as the
lid and wrapped it around the maf, then force it into the otrcai tube.
It needs to be pretty tight and then hold it up to the light and
make sure their are no gaps.

I think i will just get a heap of that foam padding and make sure everything is sealed again.... just to be sure.

Then i'll get a MAF Tune for the car.

:rofl::rofl::rofl:

And all this from the same blokes that when I traded my old car (cam, mafless etc etc) in with them rang me up telling me that the car was stuffed and wouldnt run after they had flashed a stock tune back into it.:lmao:

This was after I specifically told them NOT to do it.

If they can't tell a car is mafless & cammed etc - how are they going to fault find anything on your car?:confused:

They probably wouldn't even know what a cam was anyway! Its funny how they are in the business of selling cars yet they know f all

Forget the MAF just go straight for a MAFless tune you won't regret it. As far as the police are concerned shouldn't be an issue, the GTS was MAFless from the factory.
