*** Zip's EBL Preview ***

**NuSiEr** · May 8th, 2001, 07:57 AM

JRSC people have been waiting to hear how Zip?s EBL is coming along. I?ve been using the EBL for a few weeks now and it works as advertised. Zip is still doing minor revisions on the programming, so I can?t say exactly when he?ll go into full production. It will be very soon though smile

Components & Installation:

The boost controlling section of the EBL is installed near the bypass valve. In order to install the unit, the S/C needs to be lowered temporarily from the intake manifold to access the bypass bracket screws. The unit is mounted with a new supplied bracket. This wasn?t a problem for me since I had my S/C pulled for a gasket replacement. I also needed a longer heater hose to make clearance.
Of course there is the Brain. I highly suggest whoever is installing this have good knowledge with reading wires and soldering. There are a total of 16 ports but not everyone goes to the ECU. There are approx. 5 cut/splices and 2 taps to the ECU. The rest is for the boost controlling unit, beeper, power/ground. Lastly, you need to hook a vacuum line to the EBL MAP sensor.

Here are the features of the EBL and comments:

Auto Boost mode ? Easy to use. It?s selectable anywhere from 1-14PSI in 1lb increments. All you do is select how many pounds of boost you want to run and the controller takes care of the rest. Zip says the auto mode ?may? give a lower boost reading than set, but I didn?t notice any lower readings during my testing.

Manual Boost Mode - This mode is very accurate in controlling boost levels
because you manually enter the boost controlling regions with respect to
throttle position. The EBL reacts in four stages directly relating to the
position of the throttle position sensor. So basically, each stage will ramp
the bypass valve closed, with the 4th stage being what boost level you want
to achieve.

Scramble boost ? Self explanatory. With the hit of a button, you get full boost!! I?m trying to keep off that button until I hit the dyno. Very hard to resist. 

Digital Signal Processing Mode- This is the mode where you manipulate the ECU signals. Each mod is user selectable, so you can turn them on or off depending on your needs. You can also select when they will activate by reference of the EBL?s MAP sensor.

TPS Mod ? This is Rjaffey?s TPS trick, but with an improvement. The original trick worked off the JR pressure switch. This one works with the EBL?s built-in MAP sensor, so you can activate it anywhere, even before it sees boost, whereas the JR pressure switch triggered at 1 PSI.

MAP Mod - Modifies the MAP sensor voltage to richen the fuel mixture.

IAT Mod ? Replaces the JR fuel enrichment relay.
VTS Mod ? You can select Vtec engagement from 2500-5000 RPM in 500rpm increments. (I believe Zip is changing it to 100rpm increments) I have mine set at 4500 and it seems to pull stronger at WOT than when it engaged at 5500. I haven?t been to the dyno yet, so I can?t say for a fact which rpm is best for Vtec engagement. The nice thing about this mod is it only activates when you are at WOT, so regular driving is not affected.

AF Mod ? This is a safety feature which I experienced and must say is a plus. User selectable to warn when you are running lean. If the A/F ratio runs lower than what you selected it will give a warning beep. I had my rise rate too low and was running lean at WOT. Good call on adding this feature.

Valet Mode: Don?t want those punks beating on your ride? Put it in valet mode and you have zero boost.

So those are the features. I?m currently using manual boost mode since I like the adjustability. If you?re lazy then use the Auto mode. I just like to tweak smile

Since I?m using 310?s now, I?m not using the IAT mod or the MAP mod, but that?s my situation. I no longer have any tip-in detonation in any way. I think the combinations of mods provided should make tuning a lot easier for any JRSC.

Sounds great!

BTW, I don't know if anyone else works in a medical field, but as soon as I saw EBL, I thought "Estimated Blood Loss"

HOLY CRAP! I had no idea the unit was going to be that robust! I thought all it'd do is the set the boost like the auto boost mode.

Very trick ZIP!

WOW!!!!!!!!!!! I want I want I want, how much how much how much, when when when is it available to us?????????? smile

Is max boost dependant on your pulley size? Or does it matter?

ZIP: Speak to us, when is the news conference? wink

Thanks for the update,

Is this a boost controler for the supercharger. How can this be? I'm lost
What is EBL?

**BoostedEX** · May 8th, 2001, 01:36 PM

So this boost controller regulates the boost by physically moving or restricting the bypass valve itself?

I had the opportunity to take a brief ride in NuSiEr's car (thanks, man smile

) and can say that the EBL is a very nice piece.

The way Zip modulates the onset of boost is a very nice feature. You get a nice smooth transition instead of a sudden blast to maximum boost.

Tip in knock was completely gone, too. biggrin
