Eboost2 cuts out

null@example.com (TINKRD) — Fri, 04 May 2012 17:18:15 +0000

Anyone ever have any issues with their eboost cutting out on high psi? There's been times where I hit 18+psi the eboost screen goes blank. it still has power bc the led gauge will still be lite up. Buttons won't work. I have to turn car off/on and then it works normal. Gonna check the power/ground but would think that if it's that it would do it all the time.

You can see it in the below video on the 2nd run.

Dual Bovs?

null@example.com (diesel1) — Thu, 12 Apr 2012 18:02:40 +0000

Can I control 2 of the seloniods from 1 of the tps controllers? Im trying to control 2 bov's using only one controller to reduce the wiring. or should I run the signal wire to a relay?

Supersonic BOV

null@example.com (Evo9) — Tue, 10 Apr 2012 17:47:01 +0000

My Supersonic BOV opens at 21psi during boost leak testing with all vacuum lines properly routed and with the BOV cap all the way tight. I need to hold & achieve 30-40psi with my turbo setup. Do I need a heavier spring or is there something else I should be aware of?

Love your product, Thank You in advance!

Eboost 2 psi raises per gear at track

null@example.com (jodadejss06gt) — Mon, 09 Apr 2012 20:08:27 +0000

Hello, I have an eboost2 on a 06 mustang gt with at 67mm precision turbo, other brand 38mm wastegate with a 5.7psi spring, 4.6L V8 and I also have a QTP electric cutout. Target boost is 9psi. When I tuned the car with the controller I had it set up with an SP of 25, GP of 5.5psi, and SN of 20. This held a good 9psi once fully spooled w/o the QTP installed. This past weekend I went to the track and had the qtp cutout open and at a lower SP value(started low-SP5) the boost would start low around 6.9 and climb to about mid 7's in 2nd mid 8's in 3rd, and then ramping up higher in 4th before I crossed the line at 124mph. I did try to adjust the SP value up to 15 to gain a little more pressure in 2nd & 3rd and adjusted the sensitivity up to 21. It seemed to help a little bit but I still crossed the traps with about 11psi. Thats too much for what I'm shooting for in 4th but less than what I want in 2nd and 3rd. I've considered just wiring the grounding wires to switches to adjust between boost groups but its hard to shift and then have to worry about flipping switches too. Is there anything else I can try? It doesn't seem to do that on the street, but I don't normally go WOT for 11seconds on the street and 1st thru 4th gear. Its also hard to do any 4th gear pulls as I shift from 3rd to 4th over 100mph. This is using a 2step and wot box as well so between shifts I'm keeping the go pedal matted. Thanks in advance!

Here is a video of the vehicle from this weekend. In the 3rd pass or so you can see the eboost2 in a vent pod and can notice the bar graph under the digital display start to increase as the gears go up. Please help.

Boost spiking during shift, eBoost2

null@example.com (kingkiller) — Mon, 09 Apr 2012 02:42:47 +0000

What are some reasons or things I could check that might be causing my boost level to jump significantly during shifts, then come back down? I have an automatic transmission, using the 2-port connection method 1. Thanks,

Mike

let me know if/what other info you need, thanks

Re-mounting an eBoost 2

null@example.com (AFF Motorsport) — Sat, 07 Apr 2012 01:26:02 +0000

I'm re-mounting my eBoost 2 and was wondering if I unplug the unit would it loose it setting?

I don't want to loose the current set up I have as it works Great.

Which RPM setting for 04 Cobra

null@example.com (kingkiller) — Fri, 06 Apr 2012 03:30:10 +0000

What's the correct setting for an 04 Cobra for the RPM signal? Is it something other 8 cylinder because of how the ignition system works on this car?

Thank you,

eboost street wires connection

null@example.com (BB4G63) — Thu, 05 Apr 2012 11:39:15 +0000

Hi all
I just bought a new Eboost street 40 PSI, but I am a bit confuse of connnecting those wires
I dont have aux devices and external switch, so I leave white, green and orange disconnected.

And now I just connected the power,ground and solenoid wires,
but Is necessary to connect the RPM wire?

cause at the moment, the controller is working fine, however the solenoid seems not working,
I got overboosting even the controller is well set, and live boost is totally different from the boost gauge.
Then I have disconnected the solenoid wires, the live boost doesn't change on the controller.
so I suspect the solenoid wasn't connected.

can anyone give me some advices?
of I must connect the RPM wire????

thank you

E Boost 1 Boost Cut Input

null@example.com (crum) — Mon, 02 Apr 2012 11:12:02 +0000

I'm looking at installing an Aquamist water/meth injection kit into my vlt and was wondering if there was a way to hook up the failsafe option it has into the e boost so it will drop from sp3 back to sp1?

Theres a couple of different signals which the controller outputs

F. SAFE OPTIONS:
CLP, FS0, FS1 configure the “map-switch” output,
- CLP (factory default): Output voltage is clipped
from 8V to 5V.
- FS0 (factory default): Fail-safe output to ground
upon activation
- FS1: Fail-safe output switches from 0 to 5V or 8V
upon activation.
(this fail-safe output option is on the pink wire of the
grey harness.

Raceport BOV and supercharger

null@example.com (sagec1001) — Sun, 01 Apr 2012 20:19:01 +0000

I recently purchased the raceport BOV and need to use a different srping. I have a procharger supercharger set up that can/is vented to atmosphere. At idle the car has approximately 8-10in of vacuum depending on engine temp. What spring that turbosmart sells do i need for the supercharger to function properly and have the valve open at idle? i've read that a 3# spring is recommended for superchargers but can't find a good description of what is included in the spring kit, etc. What spring/model number for spring could you recommend for my application with the raceport valve?

Thanks,
Cody

Turbosmart Dual Port RED: TS-0205-1020 (Mits. Evo 8MR-JDM)

null@example.com (pangyau) — Sun, 01 Apr 2012 02:25:23 +0000

Application on Evolution 8MR (JDM/Stock condition)
Location: Malaysia

I just bought & install the Turbosmart Dual Port RED: TS-0205-1020, replacing my existing BOV (stock). Previously on stock BOV the car managed to boost up to 1.5 bar (DEFI reading) then after installed the Turbosmart it could only manage to boost up to 1.3bar (DEFI reading).

During installation I try 2 setups.

1st Setup.
Fully recirculation similar setup to stock condition. The back pressure/surge are too high can be notice by loud of noise produce back to turbo. I tried by turn the dial from Soft to hard. When at Soft dial, I unable to boost up only manage to get 0.7bar. While on Hard dial, it’s able to manage around 1.1bar but resulting the back pressure/surge to high. Worried of the out come, proceed to.

2nd Setup
I try 50/50. After tuning the dial around close to Hard dial, I manage to boost at 1.3bar. That’s the best I could get but the back pressure/flutters happens while changing the gears (less noticeable compare to 1st setup). While at Softest dial I could only boost up to 0.7bar. Very weird for me.

Luckily my idle still normal for both setup.

My Q, is it normal the boost reduce after changing the BOV?
What is the Maximum capabilities for this BOV to hold boost (what Bar)?

Your assistance very much appreciated.

eBoost2 sensitivity level

null@example.com (Paulyy) — Wed, 28 Mar 2012 14:45:40 +0000

i've got an eBoost2 in my car, the problem is that it's not a consistant boost curve.

I'm not really sure how to tune the sensitivity value.

is there a specific way to do this?

I was thinking to put it on 0 and work my way up by 5 until it straightens out

What should i expect when i put it on 0?

Here's a data log from my Innovate LM-2 using a GM 3Bar MAP Sensor. IICR the sensitivity was set at 10 on this run

****Boost line is red

EBoost2 solenoid connections

null@example.com (LRGElise) — Sun, 18 Mar 2012 16:14:11 +0000

Hi,

I just have a question regarding the connections to the EBoost2 solenoid. Per the instructions that came with the unit, for an external wastegate using the 2-port connection method 1:

Port 1 goes to a boost pressure source
Port 2 goes to the top port of the WG
Port 3 goes to atmosphere

I was checking out an online setup tutorial from turbosmart for an external WG setup on an EVO and they set it up as follows

Port 1 vents to atmosphere
Port 2 goes to the bottom port of the WG
Port 3 goes to a boost pressure source

This seems to be the setup for an internal WG per the included instructions.....

Can anyone shed some light on what the proper connection method is?

I have a WRX with GT35R setup, external 44mm HKS WG.

Thanks

Ian

E-Boost street wiring.

null@example.com (mattmac) — Sat, 17 Mar 2012 20:30:08 +0000

Hello, i am in the middle of installing a E-boost street on my Z32. Now my questions may sound a little newbish so bare with me, this is my first EBC install so i'm going to play it safe.

At the moment i have the EBC wired up with just the ignition/ground and RPM signal wire. I don't have any Aux source so i take it i leave that wire disconnected. As for the green wire. Does this need to be connected? From what i gather its so i can externally switch my boost setting?

So at the moment the green, orange and white wire are disconnected. Is this alright?

Thanks.
