How to get from a set of initial conditions, to a set of repeatable while loop functions.

Several questions in one here!
I am trying to write a lap simulator. I have a series of equations that needed to be processed to get a range of initial conditions (initial speed etc). I now need to iterate the same series of equations in time steps of 0.001s in order to get constantly updating values (as the vehicle travels down a straight). How do i get a loop to read these initial values, but then create itself a log of the constantly updating values to use for the next iteration?
I am using a while loop (probably with incorrect coding grammar) as a repeat loop would be perfect, but is unavailiable.
This is where I am;
while true
if Vn > Gear4max
TractiveForce = TracForce5;
elseif Vn > Gear3max
TractiveForce = TracForce4;
elseif Vn > Gear2max
TractiveForce = TracForce3;
elseif Vn > Gear1max
TractiveForce = TracForce2;
elseif Vn < Gear1min
TractiveForce = TracForce1;
end
if TractiveForce > (MuAcc*Downforce0*Mg)
An = ((MuAcc*(Mdistrear*Mg+Mdistrear*Downforce0-Drag0-RR))/Mg)*9.81;
elseif TractiveForce < (MuAcc*Downforce0*Mg)
An = ((TractiveForce-Drag0-RR)/Mg)*9.81;
end
Vn = Vn+(An*Tstep);
Sn = Sn +(Vn*Tstep)+(0.5*An*Tstep^2);
Tn = Tn + Tstep;
Downforcen = CLA*Vn^2;
Dragn = CDA*Vn^2;
if Sn > 500
break;
end
end
Secondly, how can I put an upper limit on the value of Vn, for example. It is limited through gearing to a certain speed, how can I make it recognize that?
Thank you for all help :)
