I just installed the kit along with the flow gauge,failsafe and boost bypass.
my failsafe is defective, it will not send out the 0-5volt flow signal NOR the 12V boost bypass signal. The controller is fantastic in that it flows at the correct setpoint and turns off imediately when it suppose to.The kit didn't come with enough tubing, was about 4 ft short. The boost bypass solonoid only enables 15psi of boost if your not using a MBC. the kit comes with the nice push connectors so no need to use clamps. I did come up with some nice custom failsafes. I will provide pics of all of it as soon as my install is done. Hopefully my i can get a replacement failsafe quickly.

 

Still have failsafe issues. Tried hooking it every which way and no luck. Every time is waste gate boost only.

I so wish I could figure what I doing wrong or what is wrong period. Need to call Labonte and talk to them.

 

there is no way around it using that solonoid. it creates to much back pressure thats why your not getting full boost. I think the best way is to use the 12V output of the failsafe and connect it to a relay to disconnect your stock solonoid so the ECU powers a dummy solonoid doing nothing. That will drop you down to wastegate. as shown below

 

I think we should use the bypass solenoid in NC position and tie the inlet to the turbo nipple and the outlet to the WG solenoid (all connection bypassing the pills).
That way, normally the the bypass solenoid is close and not doing anything with the system but when it opens it sends full turbo pressure to the WG actuator.

 

the only problem with that is during a failsafe yes it will direct boost to the wastegate. BUT the factory solonoid is still open so all that boost will do directly out of it instead of the wastegate as shown below.
red path goes to orange path because of least amount of resistance.

 

Labonte is AWESOME, They responded over labor day weekend to my defective failsafe. Now that is customer service at its best. When the owner is out doing the dirty work traveling and trying to make his product known instead of hiring salesmen. That tells me something about the company. I am completly sold on this company. Way to go Labonte!!!!!

 

I currentlly have the coolingmist stage 1 (which I got from my cousin).

I want to install the VC-25D for control purposes.

What else do I need to connect this?
Do I need the flow control solenoid? or is the pump activated by the controller itself?

Verifing Labontes diagram for the VC-25D , I dont see any solenoid or check valve, just the tank-pump-injector.

thanks in advanced

 

run the coolingmist stage 1 with a solenoid valve.

a progressive controllers will add nothing to performance but tuning headache.

invest the $ in a good failsafe like the aquamist dds3 or/and zeitronix

 

Yes I understand about the failsafe.

But getting into the controller, isint it better for the injection to enter gradually insted of full on or off. Is there no hesitation, what about driveability??

 

in theory its suppose to be...in reality, your AFR will be all wacky because of the systems inability to respond to the rapid changes ( both +ve and -ve transients)

the consistency of a on/off injection and a good tune - you will NOT have driveability issues.

 

My progressive controller has progressed to an on/off unit over the years. Stock turbo just hits boost and high airflow too rapidly to make any use of it.

Another thing is the peak boost is where effects are most needed but boost is fighting volume of methanol. As rpm go up near redline and boost falls you start to reach a preignition limit with alcohol due to it's characteristics but the system is spraying more.

An ideal system might be to have higher concentrations of methanol at high load with an increasing H2O concentration as rpm goes up. Cant find the chart right now but shows the knock and preignition limits for gas, water, and alcohol.


Found the chart:

 

My Failsafe has been giving me a headache for a few weeks now..The red light will go on(failsafe) as soon as the meth is activated and will stay on until i let off. I havent touched anything or messed with anything. A/Fs are good so i know the system is working properly just the failsafe is sensing some sort of issue..

Anyone?

 

k2, my failsafe has been acting up like that as well.. i msged dan week ago and he gave me instructions to test the failsafe unit itself to see if its acting up but i havent gotten a chance to see if its working properly or not.

But ya sometimes itll be activated as soon as it sprays then stops when i let off...while some other times it wont.

 

My failsafe has been doing the same thing. Can you send me those instructions on how to test it?

 

Not implying this is the case but depending on the settings of the controller (start/full), the rate of control parameter increase (boost or airflow hitting hard), the setting on the pump, and length tubing or other restrictions, the controller may be sending a pump driving voltage high enough to energize the boost defeating solenoid before your flowing fluid outside the trigger range.

I had this problem with the first gen solenoid with lower resistant coil (2 port). Try adjusting the control settings
