I actually have a 2 part question. The first part, does anyone know if the A604/41TE was ever used on the 2.5L 4cyl engines? The second part is, what is the earliest engine control that can be used to transmit the data needed to the transaxle computer? Specifically, can an 89 TII SMEC do this? If I need to go up to SBEC or SBECII, then I will have to see what rewiring of the car would be required, but I would gain full sequential injection. What I am looking for is a way to slow down the engine at higher cruise speeds, like the 70 mph (that everyone ingnores) in WV. The other trick would be to use the transaxle computer for the autostick so it can be driven like a manual. Thanks,
