leaning the engine out makes the car run hotter and stronger right??
are there any repurcutions??
i can go 10% either way what do you think i should tune it for
daily?
and
Performace?
oh d16a6(CRX si)

 

NOBODY??? plz...

 

leaner mixtures burn MUCH hotter and can cause serious damage to the engine. The idea is to run right at the point where all fuel is being burned, but the car is not actually running lean (too little fuel, too much air). You need to get a professional to dyno tune this for you.

i thought a little richer than stoich like a 12 or 10:1 af ratio would be the best for power.

 

so if i run lean i just cant watch the oil temp to get a good gague of how my engine is doin?
what %?

 

A/F RATIO COMMENT

9.0:1 BLACK SMOKE (NO POWER)

11.5:1 RICH BEST TORQUE @ WOT

12.2:1 SAFE BEST POWER @ WOT

13.3:1 LEAN BEST TORQUE @ WOT

14.6:1 STOCHIMETRIC AFR ( CHEMICALLY CORRECT )

15.5:1 LEAN CRUISE

16.5:1 BEST FUEL ECONOMY (EXCEPT FOR HONDA MOTOR COMPANY)

18.0:1 CARBURETED LEAN LIMIT (EXCEPT FOR HONDA MOTOR COMPANY)

22.0:1 EFI LEAN LIMIT

I'm DUMB
no a/f gague

 

Nebody gonna help?
Can i just watch my oil temp?

 

Hey Eresuncabrun, we gotta get some dyno tuning soon. Let me know if your guys want to go and i'll talk to some people. Anyway what i'm thinking is 10% more than stoich (14.6:1) is approx ~ 1.5 % more fuel in terms of ratio's. So in turn each % you raise/lower your computer it should add/subract .15 to your A/F ratio. So lets say you want to run RICH BEST TORQUE (according to CRX_91si) which is 11.5:1...all you have to do is lower your precetage to about 7.5%.
Bottom line (if i'm right) Each time you lower your A/F controller 1% you are taking .15 from the top of your 14.6:1 A/F ratio.
