Expanded Support for Transient Fuel.

[Chevy366]

Am I reading this right ? There is no .cax LC or transient fueling for the 1 mb PCM , or can the LC be used and not the transient fueling ?

There might be a .cax for the LC for the 1mb PCM's, not to sure, need to check out the part numbers that are hanging around.

Have not fully worked out the Transient parameters for the 1 mb PCM's as yet. Really need some serious info to make sure everything is correct. Personally don't want to be responsible for suppling dud info which could burn down your engines. If some body would like to share info to unlock these parameters I would be more then glad to include them.

Sorry been side tracked, building definition templates for the early model OBD1 Holden's. Got some really cool updates to TC's OBD1 RT Tuning software that will support Craig Moates Ostrich V1 and V2 emulator and those 1 mb eproms. You folks that have been chasing tuning support for your Holden VS/VT V6 and V8 will be impressed....

One day EFI V8 will support OBD1 tuning so this might make things interesting.

Was just looking to try LC out on a OS 12592618 , 1mb PCM .
When this first got going I DLed the original .cax file (think it is for 512 PCMs) , but got side tracked and then saw that this line of development is going on so thought I would check it out see how far it had gone .
If anyone has a .cax LC file for the 1mb PCMs or has used the original .cax file on a 1mb PCM successfully .

Gil,

Could not find an operating system with this part number OS 12592168.

Found a Hummer with this OS 12592618 and the jump was at Ox29AB4.

Could you post your tune and I will have a look see for you.

Crap I think I had it already .
Had backed up HD and forgot about the data .
Thanks for the help MICK , let me know if this is the wrong .cax file .

Gil, your zip attachment contains the .cax files which patch lean cruise only (and do not have transient fuel merged in).

Yeah that looks good from here.

Ox6606 at that address is what your looking for.

Just out of curiosity what is that address Ox6606 , hex decimal added to transient fuel text ?
Keep up the good work Mick !
