Re: AFR's guess work or science?
 

Just put those lambda values into my calculator. Came up with around 12-12.5:1 AFR's for high boost, I guess thats about right, but my N/A friends go as low as 11.5:1 on their ITB'ed up all motor racers. I guess i'll have to have a trawl through a few crome .bin's just to get a feel for what other tuners are having success with.

I guess the area it will show most improvement in, is the ignition advance you can run without experiencing knock.

thats why you disable it

yep but what would happen if you hook up your wideband in o2 stock hole?

Re: AFR's guess work or science?
 

It'll work.

Re: AFR's guess work or science?
 

so runing toooo rich will not damage to wideband like o2 stock?

Read a damn book.

Ah give him a break. He reads books too.

Yes running very rich will lessen the life of a wideband sensor too.

I just said that it would work if you put it in the stock O2 hole, it's not ideal. That doesn't have to do with running rich, but your EGTs are higher in the manifold than say a foot down the downpipe where it should be.

i know it will work fine if you hook up wideband into o2 stock hole.. ok ... i just had the doubt if youre runing too rich could can to damage your wideband too. ok. and yes.. it doesnt have to do with to run too rich..

that be the only question.. ;) and yes.. im reading a book about this ----.... ;) i readed if you hook up very higher your WB in the mani , it's possible your wideband could read only mixture of one cilinder or so.. and more shits about it.... ;D

if i had a perfect english i would learn faster about ecu and tuning :-[...

jagojon.. thx brother ;)

12:1 AFR for low boost on most water cooled engines. Richer for more power. At a certain point, more fuel = detonation, but most the HMT guys will never hit that point.
