Will safc damage our engine?

[et5828]

Setting the a/f ratio different from the default value will damage our car?
Any long term side effects?
need sifu to explain

Yes It will damage your engine if not tuned well.

But the S-AFC itsrlf will not damage your engine. Your own hands did it.

oh...thanks for all the info
in other words...too lean is not good then
how bout too rich?

 

[drexchan]

not good for your wallet lor..
excessive carbon built-up lor..
You get to know the petrol station attendant more lor..

 

[stroker_kit]

ya...TOO rich (AFR<11.0) is also not good(which is the case for most factory standard ECU settings)...thats why, u need SAFC to re-tune it to be somewhere below stoich (AFR=12.0-13.5) so that u can get the best out of ur engine...

Ideal A/F ratios :
Stoich at iddling

Lean at cruising

Rich at acceleration

Rich A/F ratio condition over long term causes many problems. Among them are higher compression, preignition and excessive sludge buildup.

So its pays (literally) to send your SAFC to be tuned by a professional using either DYno or at least a Wide Band.
