Help. I used to have HP Tuner 1.4 for my 03 Z06, now I bought an 02 Z06.
How much for the latest software and how much for the pro setup?


Thanks.

Oh yeah. I like it. Now, I have an LSU4 bosch wideband sensor. Do you connect up direct to the 5 wire or do you read in the converted data from the driver box?

What degree polynomial is that? LINEAR, 2,3,4,5,6??

Dude, you are in the dark ages. Move up to XP.

I find the o2s are quite accurate for tuning. With stock around 890mv, I can see a direct and constant change after tuning. If you don't have a wideband, you can use them.

If you DECREASE the flow rate of the injectors, the car's computer thinks it has smaller injectors installed and will
command a larger pulsewidth. A good example:

given lb/hr x 454/3600 =...

:huh2: I didn't think it was that bad. Let me simplify:

Increase the flow rates by 1%, expect a 1% lean condition
Decrease the flow rates by 1%, expect a 1% rich condition.

THANKS for checking the idea out... :cheers:

For whats its worth:

SET NEW FUEL INJ DATA: Measure resistance at the poll. A stock LS6 for example is 17ohms. Noting 0 adj at 18v, the amperage is
18v = 17ohm * amp
amp ~= 1.05 or so.

New...

Please add the following:

Example:
Changes to the fuel injector slope are not always linear
when tuning the car, nor spark. Today for example, I needed to add 3% fuel up top and -2% on the low...

Thanks for the info.


:cheers:

Well, I see that you are able to READ the data (its displayed in the software), so I thought you could write it as well.
Can you point me to the inline executable address? Also, is the executable...

Chris,

Why can't the hz scale be changed?? Its just data like the rest of the file right??

I notice the scaling for the MAF is in hz. I want to
rescale the table w/respect to hz. For example, change the 12000hz to 16000hz and then shift the other values to data I have from flowing my...

Ok, I tested and this variable works for my DPXL.

don't know what csv means... :huh2:

see if this helps: from my 03 z06

40 44 47 46 45 47 44 52 54 62 68 64 59 55 50 46 40 40 40 40
43 48 51 52 50 57 52 61 64 71 77 75 72 ...

I am using the scanner and it works good, but there are a lot of params not in the program I want

In my HS3000 reference book there are a bucket load of
PRN (Parameter Reference Numbers). I have...

???

THANKS!

Is this table in the software somewhere?

What causes this error? I'm hoping one of you assembly guys can point this one out. IE, how is it derived?
We are tuning a 2004 car that has a blower and about 5600rpm, it suddently goes rich and...

I have not tested it, but will tonight and let you know...

How do I know when an update is out and where do I download it??

Thanks.
