    Are you saying no data shows in the GRAPH/TABLE when logging. If so then you are not logging against valid axis or your data PID is not valid or last your filters are stopping it.

    So is the TB the stock 90mm just ported? You need to log a considerable larger group of PIDs. MAF appears off by about 7-10% lean. Some logical assumptions. If the timing goes down but the RPMs...

    Without tune and logs with the right PID list of the issue it is impossible for anyone to give you solid advice.

    It will always pull timing base on the other modifiers. No one was arguing it didn't. However, setting the two tables the same does not allow the low octane routines to work. Meaning: you are...

    This is common misunderstanding.

    Not true. Is 100% correct. If you set both tables to be the same it has no room for the Low octane detection to pull timing. Yes it will still...

    [ECM] 2154 - Idle ETC Area Scalar should be set to 5060 for a 90mm TB. That will help some with idle. You will want to multiply 12940, 12941, 12942 by 1.07. If you do not have these they your will...

    Post tune and log if you want help and unless you have some new way of increasing TQ without air you should put the Virtual TQ back to stock. Higher lift longer duration cams will reduce TQ down low...

    Tuning OL VE via WB is the hard way. Use math there are many posts about this. Tune the MAF then use it to tun the VE.

    First should tune all on pump gas and then use a alcohol sensor and the...

    You need to log the other timing PIDs and fix your fueling issue. At 15 PSI you should be able to get 15 degrees on 91 and 18 on 93 without the meth. 825hp is the best you can get on 91 even on a...
