For boosted applications.....what are you using?

Any benefits for one over the other?

I thought I would need hybrid AlphaN with my turbo engine using large overlap cams but I didn't.
Good old speed density works really well as long as you map it properly.
Also from memory with Hybrid Alpha, the ignition is controlled by TPS only which is obviously useless for boosted applications (however somebody may have updated the software by now)

Speed density (or Speed/MAP) everytime for me!

Hi Dave. send Phil @ Extra EFI a e mail.
I think he will say Speed density

Speed density for me, just group the KPA values around the most used, I threw the logs into excel and pivoted on count to get the most used easily.

May not be the most economical but I just want to go fast!
