spark advance vs safc2
 

Worried a bit because of spark advance with safc2.. got cold sparkplugs and will run rich and with IC and oil cooler.. how can i bring back spark ??

Sell the AFC ???

hi, yes, i'm selling it already but i know some guys use the SAFC anyway with turbo and have some method to retard spark... i want to know how they do it !

Re: spark advance vs safc2
 

Some use an MSD BTM. It's much better to use a chipped ecu.

Re: spark advance vs safc2
 

i will use megasquirt... hope it works ok, never programed but will have some help from some more experienced guys.

You can retard the distributor timing.

Re: spark advance vs safc2
 

the distributor is not mechanic, how can i do that ??

Re: spark advance vs safc2
 

Ouch, that's hardly a solution.

Re: spark advance vs safc2
 

hope i dont have many problems tuning and installing megasquirt, as i see this is impossible to do without proper ecu tuning.

safc2 would work nicely under boosts till 0.8 bar i gess, but even at those pressures it wouldnt be safe.

good octane gas and cold spark doesnt garantee it.

Assuming you have a Honda, you would retard the distributor/ignition timing by pulling the distributor towards the front of the car. I have used the VAFC-1, and that's the same thing I did to mine. I had to retard mine to 7 degees BTDC to avoid pinging. FYI...I made 225whp/211ftq on a SOHC using this method.

As stated before a chipped ECU will yield better results.
