Hi, I just got my Hymee Scanalyzer and was able to do some WOT runs.

The Air/fuel ratio dropped to a low 11s at WOT. I know our cars run rich, but 11s seems awefully low (rich).

Is this normal? Or is the ECU doing this because of some reason? E.g. Cat failing?

I know this topic has been discussed across the board, but I havent seen anybody with readings lower than 12..

Thanx

They will go down to 10.5 ish or slightly below.

Ever wonder why we are down on power

mysql101

yeah - you should be able to pick up 10-15 hp just by leaning it out.

that's why we all had canzoomer ecu piggybacks a few years ago

and why i have the RB flash now

Zoom.
So the RB flash leans it out? Did you get the racing flash or just the street flash & where can I get this canzoomer, if I still can get it?

zoom44

forget canzoomer- get the rb flash or wait a little longer for the Cobb AccessPort RX-8 version.

i have the "street" flash

anybodys flash remove the limiter?!

i dont trust cobb.....leave them the subarus, when it comes to MOPs ill leave my pcm for RB

RB Flash moves the limiter from 9000 to 9300.

What other "flashes" are there right now? I know of a few separate management systems, but no other flashes.

BTW - anything above 10k rpm is bad news for for the stock and most aftermarket flywheels for the 8 - and I wouldn't want one of those failing on me.

restiller

is it safe to assume that the RB flash will increase mpg WHEN DRIVING CONSERVATIVELY since it leans out the mixture?

Jax_RX8

RB states most of the changes are above 5000 rpm with the most impact at 7000+, so low rpm normal driving will have little effect on performance and mileage.
