What's the best air/fuel meter, where in the downpipe or where manifold should I put it? It's a h23a1 in a delsol. I've heard people putting it in the leanest cylinder so that when that cylinder is rich then the rest are. I'm not sure which one that is for me. Thanks,
Matt

 

Umm Your question doesnt make too much sense... but My Autometer Air/Fuel gauge wires into my o2 sensor... Maybe your thinking of an EGT gauge??

 

autometer A/F gauge is not accurate by any means, @ the minimum you want the Greddy gauge, comes w/it's own 02

 

Yes, EGT sorry miss print. Thanks,
Matt
