6g74 route

fml. wish i'd known that before i got the maft 1.0

As a safeguard you MUST run the highest octane fuel you can buy.
Same deal when people convert from the SOHC 24v 72's to the SOHC 24v's in the magnas running the 3L ECU. You have to run the 98 octane fuel or else it'll ping it tits off.

For those contemplating this at high elevation, this is actually good news.

Got a 99 VR4 ECu for mine. Will be fully tuned and suited to a 3.5L early next year. the hopefully don't have to touch it again, Ahh, that'd be the day!

What'd you end up doing with the harness? Custom adapter or replace it? Or did you get that far yet? Is your old ecu 3 or 4 connectors?
