View Full Version : .cax file table numbering

I was playing around making a cax file last night & came to a blank when it came to the table number to use.(I was on my other computer) This had me thinking about when we share .cax files & end up with similar table numbers for different parameters. So here is the list of table numbers I have used on top of the transient tables that MICK first made. I figure if we keep a registry on what table numbers we have used it will make it much easier in the future.
Can those others making .cax files add to the list?
{B0121} Dynair calculation hysteresis
{B9000} Impact factor
{B9001} Stomp make up fuel
{B9002} Impact factor modifier
{B9003} Boiling time constant
{B9004} Boiling time modifier
{B9005} Wall mass factor
{B9006} Wall wetting min rpm
{B9007} Wall wetting max tps
{B9008} DFCO stomp compensation tps min
{B9011} Prior stomp compensation reduction
{B9012} Initial stomp compensation time
{B9013} Stomp compensation delay
{B9014} Minimum stomp fuel
{B9015} steady state enable/disable threshold rpm
{B9016} steady state map
{B9017} low map delta kpa
{B9018} high map delta KPA
{B9019} Delta tps low
{B9020} Delta tps high
{B9021} Min pulsewidth in transient conditions
{B9022} A/C Default airflow drive
{B9023} A/C Default airflow P/N
{B9024} End of injection timing trim
{B9025} End of injection timing Normal
{B9100} Lean Cruise enable

Also these (I have to check if they're correct):

B9100: LC Enable
B0121: Dynair calc hysteresis


Edit: correction: this should be B0121 and not B0105... I also updated this on Mick's list above.

Didn't I start a thread somewhere about keeping the CAX files upto date?
Anyone care to ad to it.
I haven't played with my Burb for a while....but am again now.

I'm curious to know where the latest set of .cax files for the LS1 are.

I'll update the .cax files with the new table id's soon...

I have new table id's for 12212156, 12202088 and maybe one other... I don't have them for the other .cax files (by table id I mean having the address and conversion also).

Cool! I'm curious to see what people have been playing with in my 'absence'.

Now...1:45am here...at work...time to find a dark corner and contemplate the insides of my eyelids for a bit. :hihi:

Howard, get some sleep and then check your pm/email... :) ...the .cax pixie left you a present... :hihi:

Blah....sleep's overated anyway. (had to go fix a machine...damn it).
I sent you my current .cax file...which has a few differences to yours.
Are you able to merge the two so the numbering is correct?
Mine contains the transient fuelling as well as the Dynamic fuelling tables.
Also PCM lock 'stop', platform, 4x4 etc...

Howard, I'll merge the two when I get on my other PC...

Shhhh......LOL...don't give away all them secerets Howard.

Anyone played around with those steady state paramenters?

He! he!... I'm just starting to get back into tuning the Burb....now that I have the dual 3" system on it.
Had it running hard enough to snap the serp belt the other night. Lol!
Gonna start looking into some of the 'extra' parameters a bit closer.

Arrr so you got the extractors on yes?

Had it running hard enough to snap the serp belt the other night.

And on the seventh day the Good Lord invented nitro and Kevlar.

Lol! Yeah...extractors and twin 3" stainless system. It's amazing what can be accomplished on 'nightshift'.

As soon as I put the extractors and 3" system on....the tune was almost bang on. AFR is steadier than it was with the old exhaust. I guess being able to breathe makes quite a difference.

Here's a thread on my progress.

Howard,

Sorry mate, I don't have the offsets for your OS... I only have the ones for 12202088/01250003 and 12212156/0202005 which I got from Mick/5.7ute.

I should be able to change 12212156 to suit though....right???

I should be able to change 12212156 to suit though....right???When I diff the old cax files for 12208322 and 12202088 they are identical in the address offsets.

Hmmm...not sure I understand what that means Joe?

Howard,

Lol, it was late for me...:doh2:

Is your COS3 based on 12208322...?

What I mean is: edit whichever of those two files that has the address offsets closest to your current cax file (i.e. minimal editing).

Email me a tune file Howard & I can check the .cax out for you.

I will be shortly MICK. Now that the injector stuff is near finished I can log the transient contributions to the pulsewidth with some certainty. This will aid immensely in getting some accurate table descriptions & units out there.

I was reading something (Greg Banish's book I think) about the relationship on AFR on a WB and exhaust pressure. I would assume a NB O2 is just as susceptible too. But exhaust backpressure really screws up AFR as the O2 reads it.

Cool! I just started a new from scratch tune on my 99 454 Burb using the 2000 OS. Not sure if the 2000 OS brings anything to the table, short of factory rear O2's turned off. I guess they determined the 2000-2001 454's didn't need them....

But it runs like gangbusters..... Still runs out of steam over 4600 rpm, it will rev to 5500+, but power drops off fast, so over 4600 rpm is practical limit for me and this cam and exhaust (2.75" duals crammed into one trash can muffler)


As soon as I put the extractors and 3" system on....the tune was almost bang on. AFR is steadier than it was with the old exhaust. I guess being able to breathe makes quite a difference.
