06 SI ECU RRB-A03

I have seen this ECU for sale. On your Hondata reflash information for 2006 Civic SI it states the reflash is compatible with RRB-A04 and A05. I assume it will not work with RRB-A03?

The reflash should work with the A03.

I have another related question since you guys are the ECU experts. Are the 2007 ECUs for the SI (A11, A12 that I know of) the same computer? Are they backwards compatible with the 2006 SI (A03, A04, A05)?

Thanks

We have not tested that substitution.

since 07's have VSA and this is controlled by the ecu you cannot swtich between the 06 and 07.
