hi,

does someone know which bin and definition file i need for a 91 firebird 3,1 v6? and which eprom can i use?

thanks,
nebu

 

That is a SD system, uses the '730 ECM, a '256kb chip, maskid $88. Only definition file that I know of is Tunercat's. There is a hac of it around.

If the vehicle has an auto then it is the AZTY1407 bin.

ok alright. now i only need a $88 def. file.
the only one i've found is here
But it is the wrong one because the tables look weird
I also think its for a manual car because of all the 1/2/3/4 shift gear light on stuff.

Edit: The 730_ATTA.ecu is for mask $88. Even if atta is a manual bin it doesn't change the rest.

Which tables look weird?

RBob.

 

take a look at the Main VE1 table. (graphical view)

 

Yes, looks crazy. The actual VE used is the addition of VE table 1 (either idle or off-idle table) and VE table 2. On top of that GM played some games in getting this calibration tweaked in.

To look at a graph I used Promedit and Excel.
