   OMFG this is brilliant... if it's done right. it's so obvious i'm mad at myself for not thinking of it!!

yup, it's crazy, and it only serves a tiny niche, but most of us here are right in the middle of that niche.

this thing adds a plate with an injector under the carb, and based upon feedback from the (provided) O2 sensor, enriches the mixture. it's the easy part of EFI, skipping all of the hard parts (idle, enrichment under load, choke/warmup, etc). 

in my case, i'd set my carb on the lean side of acceptable, and let this thing manage the 90% case; all warmed up road driving and highway cruise. choke, idle, pedal squirt, etc, that stuff is easy to nail down with a decent carb.

of course complete conversion to EFI is better in all sorts of ways, this isn't a replacement for that. but it's potentially a huge boon for carbed cars.  

i'm a perfect candidate; i have a new Weber 38/38 but i just battle tuning low speed to high speed changeover, and the large altitude changes i'm always driving (sea level to 8000 feet) no carb can do.

anyone tried it? it's new... 

sorry if i sound like i'm shilling for K&M. i'm not, and though i have one of their aif filters, who cares? they're air filters.

of course this is marketed for 4 barrels, as always i assume id fab my own base adapter. what else is new.
