SAFC tuning

[TSiTalonawd96]

Just wondering if anyone else has a SAFC with stock injectors on their DSM and what % correction factors. Im trying to get as close as I can to 11 to 1 without knocking (just trying to get some more power out of a stock setup). When I log with my dsm its f's up the ECU and thinks im getting knock completely stock. Just wondering if anyone else actually used a wideband and a logger to tune with stock injectors and what your lowest correction value was before it started knocking.

I know someone has done this before... I'm using Evoscan but my ECU is so slow that it can't calculate all of its values and give my logger the info it needs at the same time so its causing me to knock only while logging. Hince, why I can't just figure this out myself.

I would figure out the ecu problem first. As far as messing with the s-afc, everyone's car is different so you would be better off getting a wideband and figuring it out yourself.

There is another guy on here with the same problem, its something with the computer.. It doesn't affect anything while im not logging so im not worried about it. (In these times I don't even have a spare nickel). I had a wideband but I sold it because of this problem... It would go down to 9.5 to 1 then once it hit the certain rpm it would make it go completely lean and take about 5 to 10 seconds to recover. So as of now it was pretty much useless...

I know every car is different, I just wanted to get an idea of what other people on here had their settings at..

IMO you need to get a wb no matter what because you need to watch your a/fs at all times with these cars... and tuneing is going to be hard over the internet because it all depends on your elevation and the weather outside...

Definately need a wideband. Otherwise I would leave the safc alone, all zero'd out.

Afr's insn't the problem. Its 9.5 under WOT so I know I have a lot to play with. Knock is the problem, I recirulated my BOV the other day and the car runs much better now. I'm hoping that was the cause of the wierd knock while logging.

On a side note, while monitoring with the SAFC I have no knock at any time. Could I just watch that if it is the logger slowing my computer down causing me to knock?
