Hey guys, just wondering if anyone could point me in the right direction into getting a temporary air/fuel gauge that i can use to see what my car is doing without going on a dyno?

im not after one to mount permanently, just want to see whats going on for a tune..and i need the exact ai/fuel ratio reading, not just "rich lean stoich'

anyone got any ideas?

unless your willing to spend a few hundred on a wide band afr set up, your only option is a aftermarket narrow band guage ...or one of those jcar kits but they only tell you lean, stoich or rich

techedge, google it.
