1-2 hours. It all depends on how much you want to beat on the car to extract the most power.

Hmmm. Okay, maybe I should rephrase. Will four runs be enough to tune the S-AFC so that it is within, say, 10% of optimal? I'm not sure if that makes any sense since this is completely new territory for me, but I gather that you start with a run, check power and AFR, tune the S-AFC in the rpm ranges where it doesn't look optimal, do another run, compare results, do some more tuning, etc. Is this basically how it's done?

I've been trying to get in touch with a few places to get my car dyno tuned. I want to take it where MardiGrasMax recently took his here in MD. Someone told me he spent 2 hours tuning, maybe because he has more mods to configure, I don't know. Hopefully I get the same S-AFC tuner and hopefully he knows how to work the S-AFC2.

took me about 7-9 runs, if you have your stuff ready to go is just all about how good the tech is with the adjusting the SAFC.

Everything is ready to go, just have to get my baseline to figure out which rpm points to set and and adjust. I have a session tomorrow for an hour or more. I'm still learning the math, but I'm planning on adjusting the S-AFC2 myself and if he's available, he says he can probably help me with the adjustments. Hopefully I don't need more than 1 hour, I don't want to pay another $85 for the 2nd hour and come to find out thta I only needed like another 10 minutes.

In any case the SAFC is not hard to tune, you should dyno first and then set the RPM points. It is set up to 8000RPMs he removed those and added the other useful RPMS if you know what I am talking about since our fuel cut off is @6600 somewhere around there.

IT took me like 20 runs to get my car tuned with a S-AFC. We did it in 1 hour! Yeah , the car was really HOT. Make sure u take an ice pack with u to put it on your charge pipe. It helps a lot with the cooling of your compresed air.
