3 maps on 1 ECU...

[Straight Success]

Are there any ECU's or stand alone management systems that will allow a person to run 3 maps on a single unit? If this is possible, would you need a switch with 3 different positions?

I've seen a device that will switch between 2 maps, but never 3... It may exist, but I'm sure it's not common.

I'm sure a full stand alone system, or even running something like the Ostritch, will allow you to load a new map on the fly at any time... essentially giving you infinite options.

in the ford world, yes.

Chevys HPTuner has an option for that as well.


Ive seen a few speed density setups on imports (skyline, evo)that had 5-6 maps loaded, but Im not sure if they used an ostrich type device or ??? since they had laptops in the car.


The owners talked about atmospheric pressure effecting the way the car runs, so they adjusted it frequently.

i have a feeling that is using an ostrich-type realtime device.

the memory chips that are used in our honda ECUs are twice as large as they need to be - meaning there is room for a second map, and the Moates 2-Timer can switch between them seamlessly. I am not aware of any chips that are pin-compatible and are any larger than 2x the size, so I think you are out of luck.
