So I recently traded in my Hondata Stage 2 for the newer Hondata S200, I was lucky enough to have DynoSpot Racing work a deal with me. I had Monday off so I decided to make the drive down to visit the shop about picking up the new Hondata unit and about a possibility of a bolt-in 4 point cromoly rollbar. Since I was there I decided to throw the car on the dyno to see what was going on...

Setup is the same for both runs except the ecu:

Comptech icebox and intake
Mugen headgasket
Hondata intake manifold gasket, street setup
Hondata S200
HyTech header and exhaust, test pipe
toda cam gears +5, +5
Prelude '97+ 290cc/min injectors

Red - stock ecu
Blue - tuned Hondata

As you can guess that I was running quite rich with the stock ecu on the car, lots of black smoke.

Wow that's a big difference, how long did you guys spend tuning to notice that much change?

 

Good numbers man, now that looks like where your car should be.

 

nice and smooth...

cut and paste the link.... Lazy!

 

Damn, that is a big jump. Nice work!

 

what cams and comp

 

very impressive

 

hela nice numbers.

 

that is very very nice.

 

is there really a huge difference in the stage 2 versus the s200 hondata systems?

 

good lookin power curve...

 

AFAIK, stock ITR and whatever the mugen hg gives, 11:1 i think

 

Wow, thats very impressive. I can't wait to get my car s200 tuned. How long did you guys spend on the dyno?

 

great numbers austin. congrats to you and dsr. Hopefully I can get mine back down to dsr soon to fine tune the new goods that are coming in.

 

The reason why the gain appears so large is becuase I was running really rich with the 290cc/min injectors installed while running off the stock ecu.

It was initially a 1-1.5 hour tuning session...I was only there for the new S200 and since the dyno was open decided to hop on to see how well the car was holding up.

There were no changes from the initial tuning that was done back in November(I think).

The S200 gives you the ability to have vtec turn on via map signal and rpm vs just rpm as in the Stage 2-4, as well as air conditioning cutoff, cold idle fueling, and a few others like some sensors can be disabled, the majority of the gains are for the tuners as there are a lot of changes and benefits for them...I just wanted it for the load based vtec and the air conditioning cutoff.

That's some mad gain right there man

good for u

 

well, that does it. you've convinced me. i was trying to hold out on it, but i guess i'm going to have to call up lawrence and get hondata s200. great numbers!

 

Very impressive numbers and gain from the Hondata.

 

 

Nice!!
Looked like the 1.5 hrs of dyno tune is your best mod!!
