i didnt see any search topics...

has anyone used the perrin ebcs? we have good luck with the utec...works like a gm...

please let me know

I've done the GM solenoid thing, without the UTEC the stock ECU is a little picky about the impedence of the solenoid.. So you have to measure your stock solenoid, It may be different than the earlier Evo solenoid, but you need to match it for two reasons, first is you don't want to burn out the driver on the ECU, the second is a mismatch could cause a persistent CEL.

 

Yeah, some guy I know told me to get one and I am waiting for my buddy to install it for me. I will let you know when it gets installed. TTYL.

 

I called Perrin about the the other day, they said it would work great with a reflash, however, with the reflash, you have no way to control the gain, only the duty cycle, utec on the other hand has the gain setting you can use to fine tune response. Also, you have to wire it up yourself, no plugNpray connector. Still thinking about getting one, but I think I have some boost leaks to sort out before I give up on the stock solenoid / blled valve combo.

 

I "thought" someone had already confirmed that was not an issue in our application... I could be wrong.

 

the Perrin should work no problem.. the GM one gets quite hot without the resistor.. but it does indeed work. You have to be careful about the current because it can burn out the driver if you don't match it. The main reason you try to match the impedence is if the load is different than what the ECU expects it may throw a CEL. Last thing we want to do obviously..

 

The Perrin was the one I was talking about...

 

i used them with the utec.... on our project evo before....

but, we also use them with great success on the subies...

u can basically T tap into the stock BC wires and hook up the utec, and it doesnt matter which wire goes to which....

Ive done it with the UTEC, since the UTEC controls the solenod directly its not as picky about the load.. it loops back the stock ECU signal to keep the stock ECU happy.. With only the stock ECU, you have to be a little more careful about hooking it up directly to the stock ECU, but it does indeed work using either..

 

Has anyone figured out how to install and use Perrins EBCS (or another manufactures) with the stock ECU and a reflash?

I've been reading the lengthy HOWTO on controlling boost with the stock solenoid and restricter pills..... and I'm wondering if this might be another option.

 

Absolutely.. The trick is to make sure you don't burn out the Solenoid driver, which means you need to put a current limiting resistor in the line so you don't burn out the solenoid you put on, and damage the ECU's driver..

Read through the boost control tutorial, there are a few boost target tables (the targed is ECU Load) and Duty cycle values, you have to start by disabling the boost target and work only with duty until your roughly where you want to be..

Also, be aware that the solenoids you use have to be hooked up correctly.. For a restrictor system you have to hook up the common to the actuator side, and the NO port to the boost source and leave the NC side vented..

For a bleed system (either stock-like or with a wastegate) you hook up the boost source to the external wastegate inner port, then you T off that (similar to stock) to the solenoid NC port, the common port goes to the outer port on the Wastegate (or vented if you don't have an external wastegate)

The lower the duty, the lower the boost when its hooked up properly..

 

With the Perrin Solenoid, Its already made to hook up to the ECU, you dont need anymore resistors.

 

^^ Ya don't say....

I sent Perrin's tech department an email to see if they have any information regarding install on an Evo.... Got and auto-reply: Their out of the office @ SEMA till 11/6

Hopefully it can just be plugged/wired in without too much fuss. We'll see what they say.

 

Yeah, I talked a lot wit perrin about their solenoid. I believe it would be a great addition to my How- to control boost using the stock solenoid.

 

Since internal diameter of the stock solinoid is the last "biggest" restriction to running boost higher than 21psi, then I would think the perrin unit would do the trick.

I was looking at this a couple of months back, but have not had the time to investigate.
