If I have MTH Tuner file on my car, am I gonna be able to use SAFC II with 380cc ?

If I use SAFC with MTH how many more ponnies will I gain?

 

I guess nobody has a clue.

 

forgive my ignorance.. what is SAFC?

 

Why would you use both? If the MTH map was correct, then you'd gain absolutely nothing with the SAFC. If you did gain anything with the SAFC, it just means that your MTH map is off.

 

I was searching thru forum and I found a someone mentioned SAFC II will give more horsepower with the 380cc JCW.

 

It's like Vtech controler piggyback to tune the Air Fuel ratio.

 

Try asking in the MTH Official Support forum. You may get more support there. -- Johan

 

I was thinking about a combo like this. just get the base MTH for the DSC and red-line mods, and then tune A/F with the Apexi. But you should have a wideband on the car as well, otherwise you won't have a good way to tune mixtures.

The MTH chip alters the ignition timing, something that the SAFC does not.

 

Andy put it perfectly- AF/fuel trim is only half of the battle. You can and most [all?] softwares do alter ignition timing to optimize power extraction.
