Guys can you check my HPI file

[UAE_77]

Thanks guys....Matt, Brian , Mike and all of you guys who are tying to help. I hope all of you will get some new knowldege from my car file. to all of you.

I went through the log files and looked at the .bin from
the repository site; here are my observations.

ali1

No KR except tip-in, one event. No WOT KR
MAP is low, good idle, max is about 14.1PSI?
IAT is high, needs cold air induction? Comes
down when moving.

ali2

IATs rise at idle. ECT is higher than I'm used
to seeing. Fan settings? Several part-throttle,
steady-throttle large scale KR events about 2KRPM.
Almost certainly false. Adjust KR sensitivity,
attack/recovery rates. Seems like KR happens at
higher IATs, or coincidence?

.bin file IAT adder does not pull out spark at the
CylAir levels this car draws. This means high IAT
can contribute to ping with no correction.

ali3

0-60 in 5.9sec. ECT runs up to 201F. Believe fans
could use adjusting. Low level, false KR. Peak
timing is low. Probably can take at least 5 degrees
across the board. 2-3 shiftpoint is low in RPM,
can raise MPH to maybe 80-81MPH and RPM for all
shifts to 6000.

PE table is fat above 2800RPM. Make this 1.151 all
the way up, then check WOT spark advance tolerance.
Open Loop fuel/air is leaner than F-bodies, possible
contributor to part-throttle ping (tip-in)? Try a
stock F-body table as an alternative.

Hi All,
Here's my observations of the HPL files. I can shed some light on some of the settings in a commodore for you.

Considering a non-stock cam has been fitted... I would look to set the idle at 700-800rpm for tuning puposes at least. That should help with the shaking and the stalling.

I have looked at every table in Ali's bin file and compared them to my 04 Commodores. There are some differences in fuelling and airflow but the timing advance tables are very similar. So I would leave the spark for now.
The ECT and IAT's in the log files are typical for over here so I wouldn't worry about fan settings ( they are the same as mine). The IAT adder settings are different. Mine reduces advance at lower rpm for the same temperature.

I looked at the Injector Pulse times compared to my logs and at close to WOT his pulse times are up to 5msec longer. His IFR table is pretty close to mine, so I think his car is running rich. Combine that with a comparatively low airflow it leads me to believe it is very rich at high throttle positions.

I agree with reducing the WOT PE to 1.151 across the table to reduce fueling.

Question: If the cam has been recently installed, would a case learn be in order?

Cheers
Brian

I forgot to add, 0-60 in 5.9sec is good for a stock 245kW 2004 commodore. So with the right cam, exhaust and tune should be able to do better than that.
I think Ali needs to obtain a Wideband O2 sensor to do this properly.

Brian

Thanks all for your efort...
I will try to take all your points and do it.....

[brh26]

Hey Ali,
Do you think your car is running rich? High fuel consumption, black exhaust etc...
Is the cam only very recently installed into the car?
Do you think we are on the right track? Only you can tell that, coz you can see and hear the car.

Can you get your hands on a Wideband O2 meter?

So many questions


Brian

Ali,
I have one more question,
somewhere I think I read you had a K&N filter installed.....
Could a small amount of the oil from the filter accumulated on the fine wires of your MAF? It only needs to be a very small amount. If it needs cleaning, you have to be very careful. Do not touch the wires or you may damage them. Search the forum for how to clean a MAF if you think it needs it.

jimmyblue, do you think it could be a contributing factor?
Brian

[jimmyblue]

It's hard to say about the MAF, since we have no LTFTs
to look at (usually the give-away).

I was kind of surprised about the very low CylAir numbers
however, given this is supposed to be a cam & headers car.
The difference in elevation doesn't look enough to make it
be .65g/cyl (14.1 MAP) when my stock cam, manifolds car
sees 0.76-0.80 at 14.5 MAP. So there could be some airflow
low error (then again my setup is highly fiddled, non-stock
MAF and VE tables, so maybe mine is faked high; however the
commanded vs actual AFR seems spot-on, in my case).

Pulling the K&N and cleaning out the MAF, though, is just
good hygeine and no reason not to take the time (and,
if it's an actor, tuning to a sticky situation is a waste of).

Hi guys,
Ok, I think all of you are right. The exhust are black, and not only that if you stand behind the car for 10 sec you will feel the amount of gas coming out from the exhust. My brother mentioned that he did TB bay pass, Ported throtel body. And the K&N is out for about 4 months. I do feel that the car is rich...
From where Can I find wideband O2 senser? I just need any place to order from.
I found one of my friend had his computer sent to Astralia for modification, if you guys are intrsted to have a look let me know.

From where Can I find wideband O2 senser?

http://www.innovatemotorsports.com/ <-you want the LM1

There are others out there but I can only recommend this one since it's the one that I use. I'll try to find some more links for you right now.

This is the specific one I'm talking about:

Thanks guys,
Mike thanks for the websites....I will look know and I will make my order as soon as possible.....

[brh26]

Ali,
I don't suppose your friends car is the same year of manufacture as yours?
Or even if you can find another car the same year as yours and download their bin file. You may be able use the settings as a guide or even use that bin file.

Well worth a try

Brian

[UAE_77]

Hi Brain,
The car is the same year with almost same modification. His car with poster heads, Comp Cam lope 114,rockers, lifter, springs all the hradrs with full catback system, Thermostat 180, K&N filter, gear ratio 3.73,Custom computer, RK sport MFA, 8.8 spark wires. When I went throw his bin file...Most of the numbers are the same except for the gear shifts, it is better for racing. And some other stuff I did find it diffrent. ex.

mine in the top and my friend is down.

Question: I took his gear shifts to mine...Normal and Performance and I left the hot stock is it OK.

Thanks guys.

Ali,
check your mesaages, I sent you a PM

Brian

[brh26]

Ali,
I sent you another PM and an alternative email address via email.
