i know most of the people here hire somebody to tune their car. but a question to those that tune theirs.
do you tune from 1000 rpm all the way to 7100 rpms on open loop? (open loop =>40% throttle)
if you tune from 1000 to 3000 rpms, what is the ratio you tune it at? 13.0 or 14.5?

 

nobody tunes their own car?

 

f/i or n/a?

 

14.7 is the most effiecient for emmisions 13.6 makes the most power, 12.6 makes good power and is still safe

 

WTF You cant just say XX.X A/F makes the most power you are WRONG. Every car is different. Some NA Z's make good power at 13:1, others at mid 12's A/F. And your 12.6 for safe power is BS with FI, that is way to lean for anything above 3500rpm's...

 

n/a. I understand that every car is different. Usually there is a range where you tune at. most popular is between 12.5 and 13.1.
Do you guys tune from 1k rpms or 3k up?

 

Most Id say from 2500-3000 and up....my UTEC with TN kit is tuned 3000 and up, below that its the stock TN flash.

 

I guess tn means technosquare? cause i did that too and my car seems to be on 13.0 at wot between 1k-3k. some people tell me it should be in closed loop between 14.5-15.0.
