Hi ı wanna learn whats your general afr ratios when you tune normal mod cars, for example my mod list.

 

Check out any of the $117 so called "case studies I have posted on these forums" Pick onme that matches your mods and you will see how i tune it

 

Yess thanks but ı just want to ask 11,5 afr is dangerous at 21 psi for daily car?(ofcourse it depends on the tuning but pls answer generally)

 

Of course not. 11.5 still leaves plenty of room. Our cars can handle 12.0 on pump gas at 21psi, but people don't tend to tune to 12.0 so that there is room for bad gas or weather fluctuations.

 

hımm ok than what is your afr ratios?

 

Mine are in the 11.4 - 11.8 range on pump gas (22psi Custom Dynoflash).

Why is it you're asking? You plan on doing a mail in flash?

 

No ı have already ecutec reflash but now my afr is 10,9-11,0 and ı feel tha car is stiil rich and ı m planning to buy this week tme turbo+jıc headers so ı need to retune and ı am searching the safe fast tune thats all

 

i just got an evo 9, but had an 04 8 and had the basic dynoflash flash. Put it on the dyno at topspeed and doug said it was amazing how well my afr's were for being a non custom flash. 11.5 all the way to redline at 21.5 psi. Made 284 whp with dynoflash/tbe/mbc

 

Okk thanks for your reply and need more reply
