BZPT 51 xdf injector scaling

[efidyn]

Do both addresss need to be changed? I can see them and in decimal one is way larger than the other.

its 16 bit... set the xdf item to the first byte then 16 bit and it will use both bytes in the equation.

Dont quite understand as I have not gone this in depth before. Are you using tuner pro with this? I can use tuner pro, but am using another editor at the moment and need a little more help with this if you could.

well its a bit hard to help without knowing what editor yourt using, Jayme is referring to Tuner Pro 5 though.

As the vehicle in question is using super 6 injectors I used the hex data and set them both to the parameters in the info sent. This worked good but need just a little more taken out. The editor I am using is just a very basic simple hack that another bloke did you a few of us many years ago and I can see things in 3 formats to be able to change my data. I basically have access to all site addresss even if they are not in the menu and all I need to know is what it should look like to find it if this makes sense. Is this setting a hi and low slope factor like a ford? Do both need to be alter the same amount? Thanks for the help so far as this has been invaluable and at least I am now getting back to where I should be.

no its a stadard 16 bit value. one byte is 8 bits FF hex is 255 dec. this is a 2 byte value 16 bit so FFFF = 65535 dec.
1CE8 hex = 7400 dec.

Sorry mate, but you are talking to someone who is not totally hex literate and I need it in laymans terms to be able to understand this more. I am totally computer illiterate but I am not a computer geek either. I can see the calcs on the info provided but dont understand how you got there. I have tuner pro 5 also which I can use to edit but not totllay familiar with all its functions yet.

Regards.

use windows calculator in programmer mode.
1CE8 hex is 7400 dec direct hexadecinal to decimal conversion. want to reduce the fuel rate by 5% take 7400 * 0.95 = 7030. 7030 in hex is 1B76. that is your new fuel rate thats 5% leaner.

Thanks all for your help, the final result was 173kw at the wheels na VS V6 man.

Cheers all.
