Hi, just bought a 2003 evo viii last week. It already has several mods done to it, including a greddy e-01 ebc. Problem is that it will only go up to 10-11 psi in any gear. Its not an indication thing, because it is slower than it should be. I dont know a whole lot about turbos but from looking at the manual, the e-01 appears to be hooked up right. I've heard that the wastegate spring pressure is around 10-11 psi so i'm thinking that possibly the greddy solenoid is blown? Anyone know any way to troubleshoot this further?

Thanks

 

The EBC is just not configured properly. You will need to learn how to configure/tune it or get rid of it and buy an $85 Forge UNOS MBC.

 

Are you refering to the settings in the menu like SET, GAIN, and DUTY CYCLE? Because I already set those up in manual mode like others have said to in other posts.

 

hahaha, i know what is wrong with ur ebc. I waste 3 months of my life with that piece of ****. The short version of my suggestion, sell it and get something else. u wont be able to get it to work. u have an old version and the softwear is no good with the evo. lol. I wish someone would tell me that when I had it. Now i just save u 3 months of work, what prize do i get?

 

LOL thats comedy

 

I found an update card thing for the PRofec e-01. So for $20 that i'll try before I scrap a $600 part.

 

WHERE IS MY ****ING PRIZE!!!!

 

The E-01 is an excellent unit that has many features that most other boost controllers on the market do not. Specifically for the stock turbo Evo, the RPM offset is a great asset. It is not the simplest unit to use, however.

If you are only seeing 10-11 PSI, you probably have the boost controller set to OFF. You want the unit set to Manual, not Auto.

Start out with the "Start Boost" at approximately 2 PSI less than your target boost. Start with the "Gain" set to 10. Begin with your "Set Boost" value at 10, start a datalog, and do a 3rd or 4th gear pull. Rinse and repeat until you have the boost where you want it.

When you are ready to mess with RPM Offset to hold ~21 PSI over 7K RPM, let me know and I can help you out with that.

 

Yeah, like I said earlier, ive changed all the settings in the menu and it doesnt change anything. The boost controller is set to manual, and is on. Which is why I was thinking perhaps a solenoid, or a software problem like cityhugo suggested.

 

K, waiting for the card update thing. Does anyone have any ideas if it doesn't work, cause i'm kinda doubtful.

 

Alright, after quite a while of being stumped by this one, and much researching, me and a friend discovered this. Looks like the actuator is jammed in the open position. Also, does anyone know if it is supposed to be bending at that angle? I know there is a bend in it but i thought it was kind up and towards the turbo. Anyways, i have a new forge WG actuator and am just waiting for a day off to put it in. Hopefully this will fix it. I'll post when I get it installed an try it out.
