Ok guys, here are Jim's plots. Unfortunately, the early runs are scaled differently, so it's hard to compare curves directly, but you get the point.

As you can see by the charts, Jim has done one hell of job in getting his car tuned. Do not be thrown too far off by the a/f charts. The difference from the top of the a/f charts to the bottom is less than 2 points. Most charts we see show a range of about 8 points. (10:1 to 18:1)

Jim, what is the proper range for fuel pressure with Hondata on a GSR? Also, if it is off, do you use the FPR to adjust it?

------------------
It's powered by GASOLINE damnit!!!

Boy's and Girls, this also proves one other thing.

It's not always important how much stuff you have, it's how well that stuff works together. Jim has very little (by comparison to some, myself included) done to his car. Yet he was able to pull a 224 using only the butt dyno as a tuner and minimal goodies. I was there for the first 2 runs he made, even he was surprised at what the car did (I was more pissed http://www.hostboard.com/ubb/biggrin.gif). Where the hell were you when I started my project Jim????? http://www.hostboard.com/ubb/biggrin.gif

Congrats.

Hondata is the shiznit. Look at the A/F ratio plot! It's practially as smooth as glass compared to the "band-aid" setup.

I knew this system would be a huge step ahead...and in the right direction this time. http://www.hostboard.com/ubb/biggrin.gif

Jim and Sonny, keep up the good work.

OT but, 232.1 from the DC 4-2-1 makes me wish he also had a couple popular headers to test (like to see if the Kamikazi would have put out even more on the high end for instance)

OK ladies and gents...
The wait is over.

For those who did not see my post from Saturday, here is the deal: I traveled to Atlanta to do a solid test of the Hondata engine management system. The idea was simple: Tune my current JRSC set-up (using the mechanical fuel tricks and components that I am accustomed to) to the best of my ability. Once completed, I would install the Hondata system and its supplimental components and re-tune. After TEN exhausting hours on the dyno, here are the results:

BTW, I faxed the necessary dyno sheets that I am about to discuss out to Sonny today... hopefully, he can post them to illustrate this story.

Here is my initial set-up:

'93 Civic HB with 91K mile B18C1 hybrid swap, JRSC with 3.8" pulley, Venom 320cc injectors, NO "OE" FMU, Cartech 20005i FMU, Walbro GSS-342 fuel pump, DC Sports 4-2-1 header, "lightweight" cat, Tanabe' Racing Medallion Cat back exhaust, and a 3" filter on a stick.

DYNO run #1: 224.1 HP and 161.7 lbs/ft Torque.

I made 2 additional pulls integrating small fuel tweaks in each, gained slightly, installed the Cartech restrictor, made 2 partial runs (the car went very lean, so both were aborted), removed the restrictor once again and made 2 final adjustments over two pulls and came away with the following numbers:

DYNO run #7: 229.8 HP and 167.1 lbs/ft Torque.

At this stage, I removed the Cartech, installed a set of Venom 420cc injectors, a B&M modified stock FMU, the Hondata modified ECU with Emulator, power programmer and a laptop.

After a lengthy power-up (due to a misaligned emulator chip) we got the car to fire. The first THREE runs were aborted due to an EXTREMELY rich fuel problem which turned out to be a problem in the initial set-up. After correctly inputting the fuel modifier values, the car made its first healthy pull with the Hondata system:

DYNO run #11: 204.6 HP and 155.1 lbs/ft Torque.

We immediately attacked the fuel and timing maps, and in a few short pulls, we were nearly matching the original power output of the stock ECU set-up.

DYNO run #13: 222.8 HP and 160.3 lbs/ft Torque.
DYNO run #14: 226.8 HP and 163.5 lbs/ft Torque.

By this point, we were VERY close to reaching a near perfect A/F ratio throughout the powerband during WOT. Two pulls later, after a lengthy cool down, we pulled HIGHER than the OE set-up for the first time !!!

DYNO run #16: 235.2 HP and 164.7 lbs/ft Torque.

Note: If you examine the A/F numbers at the bottom of the graph, you will see some deviation due to the LOW coolant temperatures. Dyno run #17 looks as flat as the one that you will see in #19 below.

DYNO run #19: 232.1 HP and 165.2 lbs/ft Torque.

This was the final run in which changes in the fuel tables were made. For Datalogging purposes, four more pulls were completed to provide sensor data for future tuning and analysis.

I would like to thank Doug at Hondata for all of his support in this endeavor as well as Ed and Chad at Engineered Performance for their assistance and dyno facility.

I have not driven the car under normal part-throttle conditions as of yet, so I will hold my final analysis and opinions for a few days. My initial impressions are that this system has serious potential... and the graphic system display is AWSOME... if you take your car to any street fight with a lap-top in the passenger seat showing this screen... most potential opponents will run for cover.

Looking good Jim.........can't wait to see the Dyno charts http://www.hostboard.com/ubb/biggrin.gif

BTW, did my "Secret" part(s) come in yet? http://www.hostboard.com/ubb/biggrin.gif

Uhhhm, maybe im MISSING something, but it doesnt seem like theres a WHOLE lotta difference there. I mean, 1100+$$$'s worth anyway?? Am i just missing something?

The HP/TQ figures look about the same(give or take 10), and the A/F mixtures of the HONDATA seem more "factory" type, but thats about it?

I think ill be happy with just my 290's/cartech, and 9psi pulley thank you. http://www.hostboard.com/ubb/wink.gif
