Would be interesting to know which par= t of the A controller failed.
0) 5V power regulator
1) Injector drive= rs
2) Ignition coil drivers
3) Crank angle sensor input.
4)  = MCU itself.

Do the injectors click when you press the Store button o= r when you put it into injector test mode?
Do the spark plugs fire when = you put it into test mode?
If either of those work we can rule out 0, 3 = and 4.

As for compatibility, the main difference between 13B and Ren= esis is the crank angle sensor output. The 13B has magnetic pickups and the= Renesis has a timing wheel, so you can't switch them without reprogramming= .
Then there is dwell time -- depends on iginition coils you use.
I s= uspect that other differences can be handled by tuning.
