Glad to help...BTW its Les.

Sorry les... I always thought it was with a z hahaha my bad. One other question in the csp tune what is the csp5 program switched graphs for. Are they for when you switch tunes it goes to those graph tables then goes to the new tune you selected?

Good news was able to data log all the way to work today. So now I have multiple files to start looking at. Deff getting excited to start doing this again since its working the way it should!!. Big shout out to Les for helping me.

OK after logging some stuff am i using the correct pids for this is check duration? I cant tell if this is correct or not. It doesnt seem thing that i wouldnt use any fuel pressure below 50

It looks to me like 50mpa of fuel pressure is the lowest you recorded. Which is about 7250psi. So all that is saying it's that your fuel pressure never went below that number.

So that is for the high fuel pressure then? Well why would the table in the tune tool go from 9,15,20,25,30,40.....
It seems ridiculous but I guess the cp3 could drop that low if someone is dumping a boat load of fuel correct?

50mpa is your fuel pressure at idle. The 50mpa column of your fuel pressure actual populated the cells in that column. You can see that the 50mpa column was only populated at 0 to 35mm3 which is light to no throttle conditions.

[tylerltr450]

oh ok now it makes sense. So mm3 is throttle in this case. Now it makes sense on why it starts at 50mpa. I thought I had something wrong.

ok well I just finished creating my csp tunes and I have them all done. I went flashed the truck but only the v2 switching works the csp5 switch doesnt work. Do you have to enable this with csp tune? Also on start up I increased the high idle speed to 1100 but when I gave it some gas the rpms spiked and wouldnt drop untill I switched into another tune with the v2.

Also I have this weird cell and its on all the maps. Any idea whats up with this lost cell.

That is just how the factory set it up, we are showing what they have, that isn't an EFILive decision you see there. I guess they wanted to accommodate all possible scenarios.

Should make no difference, both should work (is your CSP5 switch a genuine 'approved' by EFILive)?

Do you have to enable this with csp tune?

No, when you do the conversion to CSP5 everything is automatically enabled.

I don't know exactly what it is, it may have just been a pressure 'spike' when you lifted causing a back up of pressure that pushed it out to that cell.
