look at the bottom part of the page. Doing a non-seq mod without even having under the hood. A lot easier and easy to come back to seq.

please tell me what you think about it

Could it be that simple?? Now we just need someone (alot smarter than me) to figure out if that will actually work.

 

That looks like a very neat setup. It's definitely not the "real" non-sequential mod, but it would be cool to be able to switch from one to another on the fly. I might try it out and see if it works. I'll keep everyone posted.

 

Mach2, can you tell by looking at that diagram exactly what it's doing? What exzctly is the switching doing?

 

I would think that it forces the Turbo Control solenoids to force the turbo control to stay open, as well as the charge control solenoid to the charge control.

 

That is exactly what it does. Sounds like it should work.

 

Question: Do you think the Boost Limitation Switch do the same thing as those electronic boost controler? If so, save lots of money.....

 

My question above may be silly..... since I am still searching for a FD.. so I don't have any knowledge yet.

 

Yes and no. Yes in the way that you'll have a hi/low selector for two different boost settings. No in that you won't be able to control how much the hi/low would be. You would still need something to control how much the boost is. i.e. bleeder valves or a manual/electronic boost controller.

 

Actually, if you tap a potentiometer into the wastegate and precontrol solenoids, you may be able to manually adjust the rate of the duty cycle . I think it would work not by modulation of intervals, but by amplitude. I could be wrong though.

 

Thanks for the asnwer Lost Time and spooledUP7

 

Sounds like it would work to me ... you must control turbo control solenoids, charge control solenoids, and precontrol solenoid to have non-seq @ flip of switch. I believe looking at that diagram that system is shorting out the turbo control solenoids w/ 1st connection, charge control solenoid w/ 2nd conneciton, and breaking the precontrol solenoid w/ 3rd connection. Wastegate solenoid is left working in normal fashion which is ok because you don't have enough boost @ low rpm to have a problem anyway. I would think 4000 to 4500 would be questionable though. It might want to really boost spike depending on mods.

 

that was a question i was going to ask, what does the wastegate solenoid do?

for the record, it is on the turbo control, the charge control and the charge relief (3rd).

the precontrol solenoid isn't touch with that switch
