A9M Automatic ECU in a manual car???

[keepinitoldskoo]

Hello,

I just discovered the ECU in my '89 is A9M. According to a list I found
online this is for automatics, however the car has a manual
transmission. How will this affect the tune and drivability? Is there a
way to fool the A9M to act like a manual ECU? What's the difference?

Thank you,
Eric

The auto puter works fine in an AOD car.

To exactly mimic an A9L, you'd need an A9L or a chip with an A9L tune (or an RT).

The auto puter should have a little more off-idle timing advance (to help a converter), amongst a couple other small differences.

The problem I had with mine after the AOD/T-5 swap was that the car would intermittantly die coming to a stop with the clutch in. The A9L has a function that holds the idle up between shifts that the A9M lacks. The chip with the A9L program fixed the problem.

no problems with my auto computer in my manual car, it surges a little everyonce in a while, but I think thats the nature of the beast...
