Hi I have a green maf in my Classic 95 and I am going for more power and am going to be running a apexi pfc and was going to fit a orange label maf but my green one has 4 wires and the orange has 3 I did do this to one of my old cars years a go and just can't remember well hop some one can help me with this

Thanks

 

if your going for an aftermarket ECU then why not just run mafless?

 

Hi well with the apexi PFC you can't mate

 

Bump still need this info if some one can help thanks

 

better to go for an ESL board then, sell the apexi if you've already bought it and run mafless it will be cheaper in the long run than replacing the MAF every time it dies.
