Variables

[toilet2000]

Although I am quite new to the forum, I've been playing Automation for a long time.

Here are some suggestions to the Engine Designer, which I feel could really adds to engine building.

- Variable ignition timing (less advanced at low speed), a little bit like VVL. Two options : *Variable at a shift point, e.g. let say 4000 rpm to switch between two selected timing (like the profiles of VVL)
*Continiously Variable, varies in small increment throughout rpm between two selected timings.
- Variable Geometry Turbochargers : the fixed AR ratio in the present build prevents the use of turbo chargers. Either you get lots of torque and economy at low engine speed but no power passed 4000 rpm, or you get lots of power and no economy at 4000 rpm with lots of lag.
- Single/Twin-Scroll turbochargers selection : helps turbo'd engine building like VGTs.
- Single/Dual Intake runners : used extensively during 1980s-1990s to help produce potent engine capable of producing low speed power and smooth operation and high speed power and responsiveness. (Ford SPI-like engines)

Oh, and keep up the good work! Amazing game!

1: Every engine has that, old distributors have centrifugal and vacuum advance, new EFI stuff has a complete 3d spark table taking into account loads of parameters for deciding the best timing.

2: We need to fix the turbocharger calcuations, as you can't get realistically quick spooling modern turbos right now. VGT might come later.

3: I think that's probably a good idea yeah.

4: I'd like to add this eventually, it's pretty cool tech (and is used on a few of the cars I own)

1: Wow, didn't think you had all that simulated. Great!! (Maybe a "hard" mode where the players has to parameters those?)

And thanks for the response!

It's kind of broadly simulated, the ignition timing slider is considered to be general instructions to the engineers of how agressively to try and advance the timing, given the control systems available to them. You'll notice you can run a lot more advanced timing on newer EFI engines than old carby ones, as the more complex timing control is considered to allow you to push things further.

Ok yeah I see! I already noticed that. Anyway, it works very well like this, simpler for a lot of people! (Though my engineer-to-become self would love to pass hours tuning those haha!)

Thank you!

Ehh.. I've DONE spark tables for an ECU, it's mainly just hard work...

[toilet2000]

Hahaha! I believe you! But it's easier when you don't have to take the car for a run to test the tune

If only someone would buy me a Dyno...

If you ever find someone, tell me his name!

My old Ford Taurus SHO had variable length intake runners... and with aftermarket "big bore butterflies" the transition from the low-speed runners to the high-speed runners was pretty dramatic. I hope, if they are added, we can make them just as loud with the "performance" intake.

edit: Now I come to think of it, the Mark VIII also has a variable intake. It's just the exhaust is so loud, I never get to hear it.

Yeah, my Lantis (with the 3 length VRIS manifold on a KF-ZE 2.0 V6) makes a LOT more noise when it swaps runners @ 4000rpm.
