Accel Factor

[SVT_Z06]

Hey all!

Does the Accel Factor only help control what Aggression map you are in? Or does it also look at something else that limits power output?

For instance, I log on the same road for 1/4 hits. With stock wheels (21) the Accel Factor starts at 1.00 and increases as I go down the track. I get good times here.

I tried smaller wheels/tires (20) and the Accel Factor starts at 1.00, but then starts to decrease to 0.57 at the end of the run and I am about a tenth slower on similar if not colder conditions. Basically making the car think that it's going downhill (accel factor senses g forces).

I do end up in a different aggression table, but all of my aggression tables are exactly the same.

Is there anything that can be done in the map to make it so that the acceleration G's are the same with smaller diameter wheels/tires? It appear that smaller wheels makes the TCU think I am going downhill.

Are you swapping all 4 or just rears?

Are you changing anything in bcm?

Can?t trust any of the factory onboard timers what are you using?

All four.

I'm using dragy for the timer.

The question would be when accel rate is less than 1 is there a power limiter or torque limiter?

Post the tune and a log

Hello SVT_Z06,

No, there is no proble to have acc. factor below 1. This parameter is used to a different thing other than "cut torque or power".

I saw the email you sent to me. I was travelling and didnt have time to reply yet. I will do it shortly.

Thanks.

Well, answering here:
- with smaller tires, the internal calculation on transmission will be different
- as tires are no longer stock, it will influence this calculation
- yes, it is possible to have the calculation "always 1", but as I mentioned in the post above, there will be no negative influence in the "torque, power or rev limiter"

If you want me to change it to you, let me know.

Thanks.

Thank you for responding and looking forward to learning more!

During WOT, the 'Aggression' or ShiftID did change from 8 to 3 with the smaller wheels.

With the stock wheels, ShiftID stayed at 8.
