I saw where someone suggested starting with the ART BIN, in my 7747 ecm with prominator.---ive been using and adjusting one i got from the crossfire forum for my 82 z with crossfire.[asdu bin].------comparing the two there is quite a few diff in things reading with my tuner pro??-and they both suppose too bee stock bins.------anyone have oppion on which is better ??? or which is stock ??? or are they just diff years ???.--ive been chasing a surge on decell, as if your applying e brake on/off with the asdu bin , and the arht bin seems too as fixed ??? i could list a few things i see diff between the two if interested.

 

I started on my first 355 with the ASDU(fullsize van 350) .BIN filled with the AKTX(4.3 Astro/Safari) timing and TCC tables.

thanks fast.---i currently modi, the arht bin with my tcc, and timing tables. but see stuff a newby like me LOL THAT IS diff between the two bins. and thought they were stock ? and if so why arnt they the same [years ? ]

 

There are many differences in the stock bins of different vehicles, even with the same engine/transmission.

Differences account for
A.)Emissions requirements
B.)Vehicle weight & aerodynamics
C.)Transmission used
D.)Rear end ratio
E.)Leaded fuel compatibility
F.)LD vs HD

For example, I am going to compare fueling/timing requirements on my 5,500 lbs van vs a third-gen. The car will use less fuel and more timing. The reason is that the car cannot be left turned on so to speak near as long as the heavier vehicle. A truck may stay at or near WOT for miles when it is pulling a heavy load uphill. The truck will be setup to run richer and the timing slightly more retarded to keep heat from melting down expensive engine parts, the trade-off is emissions, power, and mileage.

 

so the asdu bin is from a full size van.---------what is the arht from--?? -pick up ????? and/or is arht bin set up for auto or stick,
