    Exclamation controlling cutoff

    hey everyone
    i did tuned many cars of gen3 and all of them responding very well.
    but i did tried today to tune gen4 and gen 5 , and as usual i did make changes to the cutoff tables to increase the RPM speed limiter and to get the popping noise when the pedal hitted at full throttle for a while, but in fact i did not get the results as gen3 cars the engine rpm speed hanging a little and the popping noise is a little slow.
    can any one help me write steps or send me files for gen4 and 5 already tuned
    mean sound like this : https://www.youtube.com/shorts/9lnuIwjJRpM

    First off, I don't agree with the reason for doing this, I think it is for Honda Civics in high school but..... Many of the gen 4 and 5 rev limiters are set to use throttle body control, i.e. it closes the throttle body to control the rpm so you get the smooth quiet limiter. This can be changed to spark controlled or fuel controlled or any combination of the three. For what you want I think you want spark limiter only, it will dump fuel into the exhaust and make the boiz go crazy lol.

    Go to Fuel > Cutoff, DFCO, in the RPM Limits column there should be a Control Methods section with a couple of drop downs to disable or enable Spark, Fuel cut or ETC. Disable ETC and Fuel and enable Spark only.

    Oh and there might be another box, I think it is called Wheel Speed Limit, this is another limiter that will work at speeds below like 15mph, as far as I can tell this limiter is always throttle body controlled so if you don't max out this limiter it will never hit your spark limiter when standing still.

    Make sure you are editing the correct load tables for the different engine types - don't just copy Gen 3 tunes.

    You can't simply copy Gen 3 songs and paste them into the other engine types' load tables; you need to be careful.
