Should I just give up....?

[UAE_77]

Hi guys..
Should I just give up HP Tuner? some people where really helpful and thanks to all who helped me. But because I'm learning and I have too many question. People don't need to help me anymore :'( If I know where to go and what to do I wont ask.
Thanks to all of you.....I guess I will just put everything aside.

There's no need to give up. This board is pretty good about answering questions quickly but you can't always expect an answer to your questions instantly. Sometimes it may take a few days to get the answer you are looking for. The other thing is your car is a little different than what we are use to since it came from the factory with no emissions equipment and runs in open-loop only. I'm not use to that nor have I ever tried it so that's why there is sometimes a lack or response to your questions. Again, I wouldn't just give up on it. It's hard starting out, sometimes harder for some than others, but you will get the hang of it eventually.

Another thing,
That's what makes your car special, the fact that it operates in open-loop only. You can be a real asset to the HPT community if you (and we) get your car squared away.

Thanks Mike....I guess you are right. When you are ecited and you need to do something, and you can not do it. You will feel that no one need to help you. Thanks brother....

There is no such thing as too new or too many questions.

What exactly are you having problems with?

Yah...from my side I will my best. I'm at this moment searching some information at the internet to try to follow you guys. And I can give you guys all the test that I’ve done and charts if you guys wish to check your selves.

Well are you trying to tune the engine after you modified it?

I assume the cam headers were not original factory parts.
I'm not a Holden expert, so I have no idea what that thing came with.

If you did change the cam and add headers, you will need to re tune the VE table. I understand that car runs in open loop? Did it come that way when you bought it?

If the car will not run closed loop you need another way to determine the Air Fuel Ratio going out the exhaust so you can make changes to the VE table.

If you are having problems with understanding the terminology used for the VCM parameters (like what is LTFT, STFT, IFR, etc) just ask.

Before you can tune it, you need to know what its doing. If you car runs in open loop only that presents another challenge, but its not impossible to tune. It will just require a different method than what most people are doing.

Honestly you guy are the best from all the fourms that i've been in. And I'm not just saying this to make you gys feel proude.

I would like to get to the VE table and edit it.
I think the VE table is :Engine>AirFlow>Main VE>Primary VE VS.RPM VS.MAP. is that currect.
If it is yes, how do I know what to edit.


(I post my first run at this site where you can find other people bin files.
if you like to have a look just go to model and choice holden then search the file name is Ali.)

Yes the car came from the factory without the cathelc convertor. I changed the CAM to Comp CAM, pacesetter Headrs, ASP Pyllys and I did take off the K&N fillter.

Did you ever confirm whether this is an open loop car
(no O2 sensors)?

If so then this means you will have to find some way
of measuring your air/fuel ratio, most likely a wideband
meter, because you do not have the "built in resource"
to use the way others do. But with that resource (the
wideband) and the enhanced I/O you can directly log
AFR and commanded AFR, and use that to determine
how much to trim the VE table (with the MAF disconnected).

I'm with jimmyblue re only running on open-loop. I am in oz and I have seen quite a few late model commodores ( I live in the HSV owners capital of Australia, just kidding) and they run O2 sensors and therefore run in closed-loop. I could be wrong, and GMH export a non-O2 sensor car to UAE, but I wouldn't have thought so. Are you sure you or someone else hasn't disabled closed loop?

BTW, One can never ask too many questions here....
at the very least they jog our memories........
I would suggest you concentrate on one aspect of tuning at a time though... be thorough and get one thing set correctly then you can move onto the next.

Posting a few pics of a log file histogram or chart might help

Hang in There
