Would you like to add fuel injectors to your list?
Ah yes. 42lb injectors. Apologies, this car has been modded over the years and doesn't get much attention these days. I should add no cats, 3" x-pipe, aluminum flexplate, bigger alternator and turn one PS pump.Originally Posted by statesman
Now we're getting closer to full disclosure.
Do you intend on tuning this thing properly, or do you just want a quick fix to stop it taking a dump everytime you pull up at lights on a hot day?... there's no right or wrong answer here, I just need to know what you want.
I'd like to tune it properly. Any advice is appreciated.
First thing you need to do is to get the B9021 cax file. It's somewhere in the cax section of this forum (I don't have a link to it so you're going to have to go and find it for yourself). Read the instructions carefully and put the correct cax file (renamed to your OS) in the calibration folder. When you next open the tune tool, it will appear under Injectors > Parameters.
Then...
Change {B9021} to 0.55
Change all values in {B4003} and {B4004} to 0.55
Zero out all values in {B4005}. (It will be wrong, but not as wrong as what you have now)
Then do a log for me. Include in your log...
MAF Frequency
MAF airflow
RPM
MAP
ECT
IAT
GM Volts
Short term trims
Long term trims
IAC counts
Wideband (if fitted and calibrated)
No need for any WOT pulls, just normal driving.
Post your updated tune file with the log.
See post #12: need-B9021-for-01250003
Ok I'll get that set up. Don't know why I haven't read anything about the B9021 cax.
It's a closely guarded secret... there's probably only a few thousand people in the whole world that know about it.
Probably only a few thousand.
