Default 99+ ECM conversion

I am looking to build a forged 402, but want to upgrade to 99+ ECM so I can tune it with MAP (HpTuners???). How easy/hard is it to convert to 99+ ECM?

No 3 bar yet. 2 bar OS support only so far. Still keeps us limited to 14.7 lbs of boost.

we don't have a 3bar option for the 98. Although you can easily use the 2bar setup and tune right at the top end for 18psi. Anything between 15psi and 18psi would just use the 18psi fueling etc. which would be slightly rich but nothing too serious.

Chris...


Thank you for the reply,
Are you planning on a 3bar setup for the 98's?
If I buy the 2bar and you release a 3bar what is involved to upgrade?

P.S. Thanks so much for the 2bar on the 98's by the way.


we are not planning a 3bar for the 98's at this time.
