Im looking at going 2 bar os But what enables PE to kick in once the MAF is removed? Have Hptuners.

 

TPS and MAP... PE enable has nothing to do with your MAF....

 

How come when I disabled the MAF tuning my VE PE wouldnt kick in?

 

post up your tune and we'll tell you why

 

Oh thats right because the 1bar map Im exceeding that, should have my 2bar few days.

 

P.E will still come on. PE is also controlled with a delay, ramp rate (enrichment rate) and torque. make sure you are exceeding all values to enter PE....

Here is another little tid-bit of info. Boost enrichment once you go two bar will NOT activate until all settings in Power enrichment have cleared. In other words. you can have 150kpa of boost, and no enrichment.... Fix your P.E settings BEFORE going to 2 bar...

 

One more question when I go to 2bar OS in fueling you will still have the PE table and then the Boost enrichment table. Which one do you use? Ive seen setting 1 in one of the two tables across the board and use just one of them, could have been setting 1 in the boost enrichment table and using the PE table. Not sure

 

P.E is RPM based, B.E is Map based....

Typically, you will use your P.E and B.E. For instance, Set the P.E to command a 12.5:1 and the B.E to your target air fuel, 11.5:1 or so...
Like I said though, B.E WILL NOT activate if P.E is not enabled.
Also, the PCM will take the richer of the two settings.....So if you command a 12.3:1 with the P.E and a 12.5 with the B.E, the pcm will command a 12.3:1 even under boost...
