749 $58 experts inside. Fuel, wtf?

Hi,

I've been messing around with a $58 bin for the past week or so, looking at differences between that and my $8D stuff.

Ignoring AE, heres the differences I found..

$8D adds fuel via:

1) VE tables vs RPM
2) Power Enrichment AFR vs RPM

Looks like $58 adds fuel via:

1) Ve Tables (0-199kpa) vs RPM
2) BPW Boost Multiplier
3) VE add vs RPM
4) Power Enrichment AFR vs RPM


Now I thought I'd get the injector constant to be about the same
via "BPC vs EGR", then import my VE table from my $8D bin. Then I thought I'd use Traxion's method to tune VE to get everything at 128.

Will the RPM vs MAP ve points be the same in these bins though?

I assumed the $58 stuff simply had ve, some pe, and BPC adder for under boost. But it has 4 fueling metods. Do they all work at the same time?

Does VE adder and PE turn off >100kpa ?

Another thing. the BPW boost multiplier. The multiplier is like 1.0, 1.05 at around 140-150 kpa. Now thats like 8psi of boost.

What is it multiplying? inj pw? I can't see 1.0 doing anything at all, and even 1.05 would be minimal in fueling difference.

best thing to do is import the VE table then ply with the BPC vs EGR to get the fuel trim correct. thats the easiest way to handle this. Then id highly suggest using the stock BPC vs boost multiplier as its gonna be fairly accurate but take your time. work up SLOW. actually AE tunning in $58 is a snap compared to all the BS in $8f $8d $88 $6e $32 $32b i really like the AE setup in $58. its nuts easy to tune. as for the ve adder. once you import your tables id highy suggest using the 100KPA coloumn from you $8d bin to populate this area. then set you BPC to ge tht eBLM int corect. itsnot ideal but its a cheaters method that is fast and easy. Don be suprised however if you need to dropsome of the VE adder.
