R4ultra, 1.4...

So I have an R4ultra, ds lite and DSi 1.4 firmware, I heard it is possible to use the acekard fix on the R4ultra to get it to work with DSi.I tried and failed.how can/ can you update R4ultra to work with DSi 1.4?

You would need to get an R4i for the dsi.

:(

Just get an Acekard 2i and you'll be set :)

Do I need to run the update on the ackard2i?

Yes, if your DSi is on 1.4, then the Acekard needs to be updated with the 1.4 compatibility update in order to work.
