I had my Euro dynoed today

Hey guys,

Just had my 07 Accord Euro on the dyno today together with the guys from Toyota Owners Club

Never had my Euro dynoed before so I thought that it'll be fun just to see where I stand at the moment so that when I do further mods with the car I'll have a starting number to work with.

Anyway I pulled 112.6kw with my current mods. Hmmm, not sure that it's all that good cos I was running really rich at around 10 for my air/fuel ratio when it should be around 13.

Question: How do I get this adjusted seeing that it's got to do with my ECU?

The Euro is going to run rich from the factory. It is worth your while to see what the reflash or some of the other ECU options come up with. There is heaps of potential in the motor waiting to be unleashed.

How many kms does your Euro have on it now? It probably is not even run in fully yet so don't expect an optimum dyno run until after 15,000kms. I noticed you have some nice mods already, trying to catch up to Peeaky? :D

Haha, yup, Peekay's too far ahead and I need to catch up. I figure that it's a few things, firstly my car's not really been run in yet (3000km) and my VSA was on.

Will resetting my ECU help with the AFR issue? Or is this really a standard thing with all Euros.

3000km is nothing. I found a significant difference in how the motor felt after 10,000kms and then after 20,000kms. Every oil change felt better and better. The VSA on will not make any difference on the dyno as they are testing in a high gear where traction control will not activate.

The Euro ECU is always adjusting and learning so resetting the ECU can alter the maps but there really isn't much point in doing that if the car is going to adjust it again. And the AFR is not an "issue" for the vehicle - it is normal. That is how the car was designed from the factory to protect the engine and keep it cool. The fact the Euro is running so rich is an indicator that power can be unleashed by taking out some fuel from the mix with ECU tuning.

The engine is not fully run in yet imo. My Euro ran so much better after around 12,000-15,000km.

Nice. In order to adjust your A/F ratio, you can either use an interceptor like the VAFCII or go for a full aftermarket ECU like the Motec or Euro1.

It gets better as the engine ages since it is an engine with hi-cam. Young engines like yours will have more friction at high RPM, and that affects dyno figures negatively. I had 38,000km on mine and got 119.6kW on a dyno similar to the one you used (Dynamics Test System).

I got comptech airbox,comptech header, FGK cat back, metal cat, 64mm TB, UR pulley, HKS spark plug,and comptech flywheel and exedy clutch( well actually, I don't think helping on making power):D

Hey, i also went there with ALN and one other euro in the afternoon session. i got 111.5 kw. its too low actually for my current engine mods. my current engine mods are Comptech header, Skunk2 Racing catback, Injen CAI, & Unortodox Racing Pulley sets.

that's low for a manual i guess, since i got an auto and achieved 112kw with my current mods on the dyno dynamics.
