AFRs at dump vs exhaust (external)

Post by Matt » Mon May 14, 2012 2:00 pm

Doing some Innovate LC1 + LM2 daisy chain testing today but with two wideband sensors installed differently

LC-1 is in the dump pipe but LM-2 is in the exhaust. About 0.2 AFR difference (leaner reading at exhaust)

Mostly these stay consistent except for on decel due to air fluctuations in the exhaust. Probably about the second time I've linked the innovate into each other but they seem to work well (apart from one empty selection item in the drop lists)

Nice demonstration of transport delay.

Was the tail pipe sniffed with or without a cat?

No cat... the one that was in there had melted and ended up being the culprit limiting my boost to about 6psi so was subsequently 'fixed'
