Although I know very little about what 'mash is selling, if it'll work with your bike I recommend a "reflash" solution first.
It uses the stock ECU, which means no rewiring (although it seems ignijet has a plug and play harness)
You're using a proven, mass-produced hardware unit that's shown itself to be pretty reliable vs. a 3rd party product.
It seems like the reflash has all the same options as the ignijet in terms of tuning.
Now if only there were still options out there for the Weber 1.5M ECU
