MS Beta: Dual table - no MAP response

Post by Philip Lochner »

When implementing dual table on MS2/Extra beta 2, I get that MAP sits at total vacuum (0%) on VE table 2. Is that a bug?

MSQ attached.
Kind regards

Oops. Yes there is a bug in the code on this one when 12x12 fuel tables are used.

If you export your fuel table 1 and fuel table 2, change from 12x12 to 16x16 and then re-import your fuel tables it should work.

The lack of map for the second table as displayed in Megatune should not impact running but it was a very simple fix and will be in the next beta.

Thanks James

I prefer to use 12x12, so I'll wait for the next beta. In the mean time I'll run on single table, although there are spots where the one bank is significantly leaner/richer than the other.

Running 3squirts/simultaneous rather than 2/alt has unlocked an uncanny amount of torque.
