As the title states. I currently have an mspnp2 for a 91-93 Na. Instead of purchasing a new unit, I'm assuming it can be modified to work on my 1994?

Looking for info and advice in regards to accomplishing this.

Thanks in advance

 

So, uh, where did you get your EFR for 1250?

 

You would need to repin your stock ecu connector or build a boomslang harness. Will be on your own doing all that, as I am not sure anyone has really documented it.

 

Ok here's an update.
The jumpers need to be changed for use on a 94 miata.
J5 and J8 jumpers are not used in the 94+ so those will need to be removed, if they present.
There is also a start signal fuse that will need to be removed.
Once that is complete, load the 94 base map.

To those who are more technically versed...Let me know if this sounds right or wrong.

Thanks
