Fuel pressure
Is anyone having luck with controlling the fuel rail pressure? I'd like to be able to bring pressure up sooner to help with my bigger nozzles, but this table isn't correct to begin with. At 720RPM idle speed I see 30 MPA when up to operating temp, not even close to the 60MPA shown for the area I'm idling at. Cold start never gets that high either.
there are multiplier tables at work between the ECT, IAT , and baro tables. dont know what software version your running but my desktop has been updated to the DSP beta and my fuel pressure column is way different than what you have posted. my lap top is not updated yet but its not here to look at. i'm guessing that the ultiplier tables are takeing affect and why your seeing less than what the base tables are showing
The rail pressure table are not correct. I just loaded a tune into my truck with 30MPA additional across the board, on every rail pressure table. Check rail pressure at idle before and after loading the tune and it is the exact same, 30MPA.........
hmmm interesting
what version are you running Down load the latest Dsp release that went out last night the lmm tables are fixedOriginally Posted by DuramaxPowered

I'll try them, I updated my desktop to the LMM DSP calz, but not my laptop......
It was brought up on another forum by Dustin from Diesel Addiction that there may be a table similar to {B1012} for an LLY that we're missing.......
The rpm axis is off. Use the LBZ

No, it's not the labels. I added 30MPA to the entire table, on every rail pressure table, flashed the tune and the rail pressure didn't change at all.
Didn't mean to be premature. I will be following this as well. I was given that guidance and was passing it along.
If you are correct, this is a big problem for me.
Ross, can you squeak this in, buddy, pal, prettty please. ??
