Hi Highlander,

Thanks for posting.

What does % A/D refer to (the axis looks a lot like TP%)...?

Hi Highlander
For Which ECM is this ? I think E67 ?

December 20th, 2016, 04:30 PM
Umm it seems to be for LS1B

EFILive has both IAT scalers in the software already for the E67.

Is there a similar table/cax for the TPS?

I.e can you modify the voltage scale to TPS position, would be handy in some conversions that use different tps or limited throttle blade movement.

as an example, a friends burnout car uses a ford tps on a big and ugly hat and based on the position he only gets to 65% at wot. it would be good to re-calibrate the range for his to indicate 100%. I'm using 01290005

Hi Highlander,

Thanks for posting.

Instead of %AD (taking it as meaning percentage of analog voltage range), do you want to make this axis the actual voltage range...?

The vehicles using LS1B used 0-5V range for the IAT.

There is for TPS scaling...
A/C scaling too and a few others.

Any updates on this? I want to use a card style maf but am unsure since I don't know what the units are.

Thanks Highlander. I will give those a try.

Thanks for sharing this Highlander.

What program do you use to make this an actual CAX file? Can I use a text editor and then replace the coding with yours and then change the extension to CAX when done? Seems too easy that way, but thought I would ask. Can you have multiple tables added in one CAX (B9996 and B9021 for example)?

Regular notepad

i use notepad++

Great, thanks! And combining coding into one cax file shouldn't be an issue?
Highlander

No. Each parameter/table/function is separate. As long as its compatible with the os, you will be fine. My cax for this os is 600kb big. And the one for 12587603 is 12mb!

My small contribution. I used this and made it work for 12593358 / 02040003. In prep to convert to LS3 card MAF.

I switched over to LS3 MAF today and found a small issue with this if you use Farenheit. Need to change the "offset" to "32".
