I know this is mostly a turbo board but I just wanted to share my dynoruns w/ the EBL equipped Si vs Hondata equipped Si. I know some of you have been following my efforts to build a boost controller for the JRSC and the project has finally come into fruition. Here's a repost from the other FI boards.

I only had a 1hr, $125 session, prior to Sonny's Hondata runs at DynoSpotRacing, DSR. I really had no time to extract all the potential from the EBL but I made the most out of it with the alotted time. I wanted to see how the different features on the EBL affected the dyno plot. The conditions were the same as Sonny's session.

Test conditions:
- 83deg F
- ~200ft above sea level
- 91 California octane gas
- peak intake temps 190deg F, as indicated by an OBDII scantool. It's about 10deg F warmer than Sonny's setup.
- max boost 11psi indicated by autometer, 10psi by EBL (more accurate) for comparison Sonny's stock JRSC setup indicated 9.5psi on the autometer but the Hondata read 8psi
- static timing 18BTDC (for great off-boost drivability)
- idle fuel pressures 20psi, static 38psi
- J&S ultra sensitivity 11 o'clock, 2 deg mid-range (2500-5000rpm) retard, 0.7 deg of retard per pound of boost
- for the rest of the mods, see link below


Here's the initial dyno run. The VTEC controller was set at 4400rpms and no other features were activated on the EBL.

I had my setup dialed in pretty well since there was no activity from the J&S.

This run was made with the IAT feature ON, armed at 8psi of boost, 5K of resistance, and to turn off prior to fuel dump at 5500rpms. MAP mod voltage was set at 2.80V, armed at 8psi.


For comparison here is Hondata's peak run:


On this run, VTEC was set at 3000rpms, IAT mod at 2.5K of resistance, set to activate at 8psi and turn off at 5500rpms

You can see that by activating VTEC earlier, some power was gained in the low end.

This was the final, 9th, run of the session. VTEC at 4400rpms, IAT mod 2.5K, armed at 8psi, and off at 5500rpms.

Here's a 500rpm, point by point, torque and horsepower comparison of my peak dyno run compared to Hondadata's.

RPM---H tq--my tq----H whp----my whp
2500---87-----115------41-------55
3000---107----123------63-------70
3500---115----125------77-------83
4000---117----128------87-------100
4500---123----140------105------123
5000---125----143------120------137
5500---132----145------135------150
6000---131----147------150------168
6500---128----144------161------180
7000---126----141------170------187
7500---125----137------183------195
8000---123----135*-----187------203*
H= Hondata

The 3.8" pulley setup does have a tremendous advantage in torque over 4.2" pulley setup. At 2500rpms my setup has 28ft-lbs of torque over Sonny's. :eek: The main problem with Sonny's and my setup is that the motor is struggling at 6500-7000rpms+. We believe it's the catylytic system being clogged up over time, prior to our more efficient present setups. Here's proof on how rich the mixture was prior to the EBL:


I'll be purchasing a Carsound cat, or testpipe , in the near future to determine if there's lost power at high rpms. I'm hoping the upcoming JR intercooler project will become a reality since there is another 20-30whp to be gained if the intake charge was intercooled.


The EBL will now be sold in three different flavors to suit different JRSC needs, from base kits to higher psi setups.



1) The traditional EBL with all the features. $480 shipped

2*) EBL with only the boost control feature. Optional features can be added upon request. $380 shipped

3*) EBL with only fuel/vtec control. This is made to compete with the JR MAP converter and JR Vpak. This is essentially an EBL without the boost control option but with all the rest of the features described here: http://www.clubsi.com/whats_hot.shtml.
$360 shipped, [for comparison the vpac and JR controller will cost $180 + $280 = $460 :eek: ] It should be called the EFVC, electronic fuel/vtec controller.

For a limited time, all EBL's for the SI and EX JRSC kits will also include an OBDI intake air temperature sensor free of charge.


*Can be upgraded and rechipped to the traditional EBL in the future. Contact zipzoo_22@hotmail.com for more info.



Thanks for your time!
