Tuning Accel gen VII

[Bosv]

Hi everybody

I am new at this forum. I live in Sweden so there are very few people to talk about Accel DFI to. I have found one !!
I have -73 Corvette with 454 LS7 in it and using the Accel Gen VII.
I started up using the uttilities to get my first map. It runs badly.
At idle it's using the lower part of the V/E table = to fat mixture.
Perhaps I have t go to Alpha/N. How do I know?
Is there any place where people are sharing their maps so I could get info from there.
It would be great to get some hints from some using the Gen VII.

best regards
Bosv
