6.5 diesel .xdf and adx

[brian617]

Here is a work in progress xdf. I have found that it matches all bins that I have except BRMM which is odd because it does have an EC mask. Anyone have any idea why a bin with the same mask has a different calibration layout, and any good ways to detect that (or inform the tunerpro user how to easily and confidently check). Maybe the BRMM bin is from an already modified memcal done by a 3rd party vendor...

I have successfully used this xdf to modify shift points, fuel, and base timing (starting with a stock BPBS bin), so I know that the checksum etc works.

It's still fairly basic at the moment but does have a lot of the common stuff that one would want to change. If anyone has any requests please speak up and I'll do what I can. I do plan to continue to expand it so expect updates in the next few weeks. It doesn't currently have any EGR stuff except for the DTC enable flags. I also haven't yet added a way to modify the pump calibration tables (or emulate changing the resistor), but I'm not sure if that's very useful since you can change base timing and base fuel.

If someone with permission wants to copy the xdf to:

that would be cool.

With some of the tables, the graphs don't work?

[newellshk]

Probably because one or another axis label isn't filled in. I've been slow doing the axis because I want to ensure they are accurate. I'll try to get those finished soon but please tell me if there are any specific ones that you need and i'll prioritize them.

In the meantime you could fill them in with a simple sequence (0,1,2...) and the graphs should work.

Got it working. At last some tool to make changes.
Can you tell what to change to get firmer shifts?
Shift time or pressure maybe?
Thx.

[newellshk]

I would start by lowering the desired shift times. Do you have a 4l60e or 4l80e? Which shifts are soft?

[brian617]

I turned off error codes 13, 17, 18, 35 and 43 but error codes 17 and 18 come back. Any ideas?

[newellshk]

It looks like the code doesn't check the DTC enable flags at all for those two. I'll find another way to disable. Do you care if the codes are actually gone or just that the MIL isn't illuminated?

[newellshk]

I found a way to disable DTC 17 by changing the instruction that increments the counter to a NOP. In tunerpro it'll be a simple scalar where you change the value from 4C to 01, with instructions/explanation included. I'll figure out 18 then post a new xdf.

The shop that did the manual pump conversion 20 years ago just pulled the SES light bulb. I'd like to re enable it. They also did a super crappy job with the pedal conversion, coolant temp sensor and few other things. I reworked the pedal already, I'm super picky lol.

I see that now about the axis, I'll fiddle with it some. I don't have any in particular yet, was just playing around with it.

I have a truck that is a manual pump conversion and I'm looking to try and fix the shift points, and turn off error codes.

Thank you very much for your work.
