flared shifts with Scaled engine size and injector values.

[paxvor]

This is my first post here but I tuned a 2008 G8 with a Vortech on it 60LB injectors larger maf all the normal stuff.

I had to scale all of the normal things for 60LB injector scaled the maf to get commanded AFR. Car made good power everything on the dyno looked to be in line.

Under all driveing conditions the car flared the shifts I did abunch of work on the transmission with out much succes.

I redid the tune with out scaleing anything I know this isn't the correct way to do it but. I had to see if the scaling was the problem.

With no scaleing the car shifts perfect.

Has anyone else had this issue?

Thanks

Scaling the MAF is wrong except when you know
for a fact that -it- is giving wrong airflow info.
MAF airflow goes to engine load, goes to trans
line pressure.

Step back to what you know about the MAF,
and try to "stick to the truth". Like if it's stock,
screened and clean then use a stock table.
Or if it's a hack-job, maybe buy a virgin to use
in tuning up the rest of the stuff and then put
the hack-job into a clean system and you'll
only have to deal with one unknown at a time.

What if you have said car that has 62.5 lb limit on injectors, how to correct air fuel?
