Hello. I've got an 89 T/A, 305 TPI that I have done some minor mods to, as well as just adding 4.10 gears. I'm using the 89Z305*.bin file with the 89v4.ecu(Winbin).
Are there any variables/array/flags with the above bin/ecu that I can take advantage of using 4.10's?
I'm using a pocket programmer with 27C128's.
Would Tunercat be any better for this(ie, more options)?
thanx

With the change in gearing you'll be able to add some timing faster, and enrichen the fuel some. THOU, there are some exceptions to that.
With the 4.1s the engine will never see as much of a load as it did before, so making heat maybe a problem. By heat I mean HP in the combustion chamber.
It's easy to over gear a car and have it slow down, because it revs so easily that it can't make any serious heat. It heat that is converted into mechanical energy, ie HP

 

Thanx for the info! Gives me a starting point to work from/on. Much, much to learn.
Building them is easy--getting them to run right is rocket science!
