not sure if this is the right place to post Hey guy im new to use a innovate lm-1 wideband AFR meter. i have coule of question? I have been haveing trouble knowing whats right or wrong. I know that 14.7 to 1 is the perfect mix when NOT under load. What im unsure about is what is a good ratio to run at wide open throttle, full load?
My set up is a 11 to 1 CR forged 355 with a cc305 cam and some mild porting i have a madz28 tune now. i still use stock injectorS (witch is not good because my duty cycle is up around 90-108%
)
Hear are some on the reading im getting:
driving around town and idleing it stays between 14.5 to 15.5 sometime it will go up for second to 16.2 or so.
going through the gears not hard just shifting at 5000 rpm it will stay around 12.5 to 13.6. At this time i will come close to 3/4 throttle no further.
NOw stopping and really going throught the gear it will dimp to 11.8 real quick then go right up to 12.8 and will hold until i get into 3rd and 4th then it will go up to 13.0 to 13.5 and floats around there.
I just woundring what you guys think about these readings??? I know my duty cycle will is really bad i planning on a injector up grade!!! Thanxs for the reaply.

Im looking into getting a wide band (the Lm-1) seems like a good product from what you are saying...
Driving around town you will want to get your air fuel ratios at 14.7 to 1
Under WOT a safe ratio is 13 to 1. Do you tune the car yourself?
