Accord Euro Dyno Results

**Suntzu** · 15-09-2008 09:30 PM

Crap!

Just had my car serviced and the door lock fixed under ext warranty.

I thought my header was a bit loud...so I got them to check the bolts and they were all loose! I forgot to tighten them after i fitted the header 12 months after the header heated up.

Cars smoother and quieter now and seems to have more low rpm power/torque.

Looks like my car was dynoed like this so I must have been robbed by at least a few kw.

Oh well ill do my next mods and redyno!

just curious mate would you say the jtune mild flash was a good buy? or better to spend the 1grand on something else?

Honestly i kinda forgot what it was like without it. I pretty damn sure my basic combination of I/H/Cat + reflash has done a fair bit. Its a lot more drivable. Im hoping it will come alive with some basic additional mods like RBC etc. I fairly confident its knocked off about .7 from 0-100km conservatively. Not that thats a real useful comparison.

I prefer to deal in facts than approximations and seat of the old butt. This as as close a dyno result you can get, Similar cars, similar temps, same dyno, same configuration on dyno:

Im about to order the RBC intake manifold. My question is:

Given I have the Jtune Mild flash, which leans the car out a bit, you can see how flat my A/F is in th above graph versus justins with a stock tune, and given I have a 5000rpm vtec point...

..Do you think the RBC might make my car a bit lean? I mean it does richen up a bit at 6000rpm due to the reflash, and justins really starts to lean off, so im hoping i got plenty of safe room for any extra leaness that the RBC should deliver.

It looks like Jtune have removed the leaness spike at 6000rpm and made it stable. Im hoping this will be an avantge when i install the RBC.

Any comments engine gurus?

dont forget your prob actually running one unit richer than what the dyno graph says... my wideband a/f logger says its 12 when the dyno reads 12.5-13...

aslong as your below 15 you'll be fine! plenty of room to play with... besides, the stock ecu will learn and adapt to all that extra air

13.5:1 is the leanest I'd ever go....
Some say my balls are big, but they are not big enough to go for 15:1!

heres my dyno:

btw mod list is
j's racing intake
maxim headers
2.5" xforce metal cat
nst pulleys

**aaronng** · 08-10-2008 09:02 AM

^^ Excellent! Looks like a slightly earlier VTEC point might help with that torque hole. Maybe 200-500rpm earlier.

**enkay** · 08-10-2008 09:29 AM

^^^ cheers =D
haha yer torque hole sucks! damn too bad ecu aint next on ma list haha

You don't have the Toda header... that makes the biggest difference!
