Exclusively engineered for use on JRSC equipped Honda/Acura vehicles with high boost pulleys. The EBL, Electronic Boost Limiter, is the first ever boost controller for a roots type Eaton supercharger developed by ECG electronics. It has allowed many enthusiasts to run high boost pulleys for the track and allow lower boost for street drivability & fuel economy without the need for swapping pulleys. The EBL has two methods of controlling boost, fully autonomous or user programmable (manual mode). The autonomous feature is a â€œset and forgetâ€? mode, which the user programs the amount of maximum boost; then the EBL will take care of the rest. The user programmable mode allows the user full control of the maximum boost attained through five distinct regions with respect to the throttle position sensor. The manual mode either extracts full linearity, or exponential production, of boost from the supercharger. Which is useful in autocross and drag racing events, respectively. The production of boost is faster than the mechanical actuator found on JR kits because the EBL boost control mechanism utilizes a sophisticated electronically controlled positioning system to moderate the programmed boost level precisely. The EBL not only controls boost, but also eliminates the dreaded tip-in detonation that is synonymous with roots type superchargers and also has a built-in VTEC controller. The EBL utilizes a 20MHz RISC processor, which samples a number of sensor parameters thousands of times per second for real time accuracy control of boost. A built-in 1 bar Motorola boost sensor, as equipped on J&S Ultras, is used to accurately measure boost pressures. The extra features found on the EBL are:

a) TPS mod: to help eliminate tip-in detonation
b) MAP mod: to richen/lean out fuel delivery (i.e. similar to the Apexi VAFC)
c) VTEC controller: adjustable VTEC engagement from 2500-5300rpms
d) IAT mod with intelligence: allows enrichment of fuel in the low and mid-range rpms but will cut-off at a user programmable rpm before the Honda ECU fuel dump to allow a perfect mixture across the motorâ€™s rev range.
e) AF warning alert: audibly and visually warns the driver if the air and fuel mixture is getting to lean at WOT
f) VTEC light: this mountable LED informs the driver that the VTEC solenoid has begun to spool
g) Scramble boost: this feature allows maximum boost at press of a button
h) Valet feature: keep other drivers from tampering with your settings and allows no boost to be produced by the supercharger

The EBL has a handheld, mountable, user interface that has a built-in 16X2 backlit LCD display with large tactile buttons for easy menu selection. The LCD informs the user of real-time sensor outputs and the amount of boost produced. So if you want total control of your JR supercharged equipped Honda/Acura place an order for your own EBL today.

From my knowledge (out of date) Zip hasn't made a Prelude application of this as of yet. I'd so much rather use this than what seems (going by people's experiences) like a really junky EMS. If I actually went the JRSC route I would need this device available before I actually commit since the EMS seems to be crap. The intercooler would be nice too, but... I guess I gotta dream for now.

Oopps my badz, I thought it was available for the JRSC ludes too

I've talked to him a couple times about this. The fuel and VTEC controlling portion are universal to all OBDII honda's meaning it will work on the Prelude. The boost limiting portion he is pretty sure would work on the Prelude setup but he just needs to see some up close pictures of the bypass valve to be sure.

schwett · 03-21-2002, 11:48 AM

yeah, he was pretty sure it would work. he lives just a few minutes from me - we had talked about hooking up at some point so he could take a close look at the kit and make any changes he needed to.

keep us posted on what happens with this piece, it sounds VERY interesting
--what kind of price would we be looking at?

schwett · 03-21-2002, 12:31 PM

price would be the same - i don't remember but you should be able to find it by searching on the fi teg forum over at hostboard/pwrhouse/whatevere they're calling it these days. or just email him. i pm'd you his e-mail. (and oh, my pm box isn't full anymore - you should be able to resend the one that bounced)

schwett, do you think that you'd try to go this route before you go back to stock if the problems continue? Since it just seems like the Prelude EMS from JR is really buggy (in terms of failures). Everything that I've been able to pull up on this product shows high promise especially if it's able to be used with the Prelude system.

nah, bandaids are bandaids. standalone or stock, if the problem turns out to be related to the EMS/POS.
