I don't know what the tuning is like on the Cali specked ECU, but I would bet they are less aggressive than the A9L.

I assume less aggressive to keep emissions down? Do you know if there is enough difference that will be noticeable?

Not 100% sure, but I'd bet you could feel the difference in acceleration.

Well thats no good. Lol Is it possible to make up for the loss with bumping the base timing up a couple more degrees?

Without knowing exactly what they did to the tuning, it's hard to say, but if you had to bump it 2 degrees to 12 to get to where an A9L is at 10 degrees you'd be forever behind the tuning curve of other cars with the A9L.


I did find this:
Quote:
The 8LD follows the GUFA strategy. A9P follows GUF1. And A9L follows GUFB. You cannot load them up and directly compare them to each other since they follow different strategies.
Since they follow different strategies and you cannot directly compare them, it is hard telling what the differences really are. I wouldn't use the 8LD if it were my choice.

Strategy is just how they go about tuning the engine.
Each of those ECUs does it differently is what they are saying.
