    Question LMM Table Changes

    Been having issues lately since I updated my V7.5. I upgraded an OS to DSP5 and the base fuel table in the Non DSP section is the same as it has been but the base fuel tables in DSP 1-4 are all different from the Non DPS table and they do not go into the timing calc field anymore. I have attached 2 screenshots. Also, in DSP2 Low Alt Fuel, it will only display NM no matter how you set it. All others will display FT/LB in the torque side pane. Screenshot of that is attached as well. Thanks in advance.

    When you make a DSP tune, the new DSP tables are populated using a script file to fill in the values. Some OS's have different values in the base file than others, so that is your issue with the non dsp tables not matching the dsp tables(it's a pain, but if you want them perfect, you have to go in yourself and correct them). As to the NM, theres several anomolies with the LMM's for about 3 years now or so. I know I posted up about the fuel pressure tables a few years ago, don't know if that one ever got fixxed or not. It just goes with dealing with computer codes and constant upgrades going on.

    Thank you for the info. The issue is the tables no longer cut and paste into the timing calc which they used to. I've used this OS to make other DSP5 tunes and I have not had an issue like this until recently. I will revert to my laptop which has not been updated yet. My PC crashed so I had to buy a new one and do a fresh install of everything. That's when the issues started.

    Yes you are correct the new DSP maps are just populated with data from a stock tune we used at the time when the DSP patches were created, unfortunately I can't think of a way around that. Pretty sure it does say in the tutorials something about this and users should be aware that the maps in the DSP (and CSP) upgrades may not match the stock values for all trucks.

    Sorry guys, it is just one of those things that because we are a metric country I just forget to ever check if things are ok when set to imperial (I think that is what you mean?).

    Thank you but I think my point is being missed. Maybe I have not stated it right. I took my stock tune, made it a DSP5 and have had no issues. I downloaded the latest release and opened the tune to do some more editing and now the tables are as I have posted. Was not an issue before. I will double check everything and go back to my last version and compare. Thanks again.

    Yes. I have only found the 1 table I posted to not switch over to Imperial. Thank you for your help.

    You mean the RPM axis isn't matching between the two screen shots?

    I think you just need to keep a copy of this somewhere..

    I know this is going a bit off topic but I think the USA is officially metric but they haven't actually changed everything (well, anything).
    They started but it never continued....

    Correct. I didn't notice it until I copied and pasted into the timing calculator that something was off. That's when I noticed the extra RPM's are in the DSP tables now.

    To add to this, the fuel pressure is not scaled right. At least in the lower RPM's. At Idle in the DSP 1-4 Tables, it calls for 60MPA at idle.
