correction points on SAFCII

To adjust or not to adjust

I have just installed my SAFCII and want to adjust the setting to lean out my air/fuel ratios. Can I use my past dyno graph as a guide to setting the SAFC? I don't want to over do it just lean it out a little for better performance.

I am getting a tune with a service in around 2 months time, but I don't really want to wait until then.

What do you think and how much should I adjust the settings??

thanks,

Mike

Dont touch the settings unless you are doing it on the dyno!

The SAFCII will lean it out, but it isnt 100% accurate. for example when i was tuning mine on the dyno i had a real dip in my a/f ratio at exactly 4,500rpm so i set the safc to decrease the read out at 4,500 but it actually moved the a/f ratio at around 3,500rpm. they work well but you really need to use a dyno to make sure.

its really easy to get it to lean out in a particular spot unintentionally - it did that with me on the dyno, but once i worked out the variance in rpm it was easy, but what ever you do dont do it without immediate dyno runs to check.

Dyno it for sure, they are so easy to adjust, mine had to be leaned out to a maximum of 20%

I was hoping that wasn't going to be the case. I suppose I will just have to wait. ....... but I suppose doing a service early isn't a bad thing...... hm.....

thanks guys.
