you can attach the log to the post if you want to so that others can see the log. you can also posts tunes too.

tables b0902-b0904 can be used to adjust what timing table you use based on the MAF if you choose to have timing tables to be selected by MAF

If you select MAP then based on what your barometric pressure is you will have to change the values in tables b0905-b0907 to make sure your using the table your tuning with for which is table C most of the time since dsp5 tunes use timing tables C

you would then have to adjust those tables based on what your altitude.

The barometric pressure at seal level is 14.7 psi.

so then i convert it to metric (Kpa) by multiplying it by ~6.9

6.9 x 14.7psi = 101.4kPa


so i then can check tables b0905 and b0907 and see if my barometric would tell my ECM to use timing table C.



looking at the picture below you can see my barometric pressure of 101kPa is greater than 83kPa so based on my location my ecm will use timing table C.

 

if you choose you use MAF draw in more than 32 grams at idle so you would be using table C all the time unless you re calibrate the MAF sensor.

that just gave me and idea

 

 

Justin, I think I'm having a similar problem with the fuel rail. Randomly it'll just drop off the face of the planet whereas other times it holds steady with my tune no problem. Possible pressure relief valve?

 

hmm I don't know that would make sense i was just reading somewhere that it can spike, which would sense since mine seems to drop after the shift when it does it.

 

if the fprv pops ur rp will fall off the face of the planet.

you can shim it or plug it. im poor so i pugged it

 

hmm dont you have a writeup somewhere around here danny? Do they even make a shim kit for ours?

 

you use the same shim kit from ppe o do it iirc, the FPRV can be taken apart on a lb7 and be shimmed.

 

this...
2004.5-2009 Release Valve Shim Kit for LLY/LBZ/LMM [FGSHIMKIT] - $9.99 : Pacific Performance Engineering, Innovations in Diesel Performance

also what about this, will this really do anything performance wise...
Ported Fuel Rail Fitting [FGPRTRLFT] - $39.99 : Pacific Performance Engineering, Innovations in Diesel Performance

 

you can take a .125 drill bit and port your own out, i did that to one and i have on ppe one, but the early lb7 have a different rail design than the later ones like yours, so it would help in rail pressure recovery
