IO expander is interesting I rang haltech but no reply yet, as I'm sure there's something I can use as I really want tps fuel supply. I got 1250cc rated @3bar which is more once std reg is under boost so should be fine and I'm looking for 450rwkw and not a kW more.
On a single walbro 460.
The Aeromotive unit says it needs a 12v old school trigger so I'll need a msd or autometer converter they reckon.
I'm spending more Money on trying to turn my fuel supply down then most prolly wanna spend on the fuel system upgrade lol.
Anyways well sort her out.
