S-AFC tuned KA-T Reliability

[ExoniX]

Im just wondering how many of you guys are running a walbro pump, 370's and a S-AFC with slightly retarded timing which is the setup i want to do.. How reliable is this ?I know that the Nsport kit simply brings an FMU and runs at 7 PSI im only gonna be hitting 5 PSI off my spring..370's, S-AFC and i think ill retard the timing to 18 degrees to be on the safe size.. Should i get a step colder spark plugs ?

You should be able to make it reliable. But it depends on how well it is tuned. You're question is too broad to answer with any certainty.

this is the same set-up i plan on using but ill also be buying a wideband )2 sensor so i can tune it nicely. if u kno how or kno sum1 that can solder u can get the DIY sensor unit from tech edge which will save alotta money

Yea, Where can i find info on the tech edge ?I already got some temporary fuel maps for the S-AFC Figured out, Just gotta make sure thta 18 Degrees timing is fine since stock is 20 right ?And also I dunno wether or not i should get a step colder spark plug, I know stock is 5, Maybe 6 ? I dunno

well i have no idea about the timing or spark plugs. i suggest u get a FSM since ur going to be doing alotta tuning and such but about tech edge this is the site: http://www.techedge.com.au/ the site provides plenty of information about their products

I got techedge 1.5 Not installed yet tho. Looks like a 30 minute install tops

With the 370's an SAFC and a fuel pump you should be able to run 5 psi just fine. Just be careful leaning out the injectors. You might be able to get away with simply leaning out the off boost rpm's and leaving the on boost alone. I just hate to see people tuning fuel without a dyno or a very accurate A/F meter. Actually, an aftermarket knock sensor has always helped me.

The timing is tricky, cause its the total timing that hurts you not the preboost timing. If you retard it, your liable to hurt the off boost driving. But safety is always a good thing. Losing a few degree's should be plenty.
