Today it was my turn to bring my car to the Honda dealer for the yearly technical inspection (in holland called APK) 1st time with eCtune!! After some instructions about the MIL and the code blinking procedure (throttle > 50%) I left the dealer... leaving the guys stunned and full of disbelief about what eCtune is and does. Well... after some hours one of the guys called. We are having a minor problem. We can't get the CO level within the valid limits. (Something I was already afraid of) \"So we think we have a real life opportunity for you, to proof eCtune.\" So there I went... with my laptop... with my girlfriend ... in a VW Lupo (My girl was so curious about this whole eCtune stuff for months, and now she had the chance to see it in action. My girl is soooo cool. She can explain to a nOOb what open and closed loop is, and where an O2 sensor is for and what the ECU does with theO2 signal) Hooked up the ECU and Ostrich. Hooked up the dealers exhaust gas sniffer thingy. Started the engine. me: Ok.. guys.. how worse is it? hd: Well... we have a 3% CO now. (I did some lowering of the mixture) hd: It just dropped to 1%. Cool! (I lowered the mixture another small step) hd: Sweet... now it's spot on.. Oh wait it drops a little bit more. hd: Ok... is 0.35% now. This is perfect. (it should be lower the 0.5% to pass the test) So.... ten minutes later everything was done. The guys at the dealer were even more stunned then this morning and were asking lots lots lots of things!!!! Yet Another Honda dealer who knows what eCtune is, and what it's capable of. Ain't it sweet? I like this kind of situations.
Nice it worked for you. I've tried to do the same a few months ago but with no success, when i lowered the CO, the HC value (in ppm i think) would skyrocket and couldn't get both in approval range.

I'm driving a 1990 EE8 (similar to EF8) Because it's build in 1990 the emision levels aren't that strict. Only thing: CO must be lower then 0.5% That's it. No HC check. Only CO. When the car is 1994+ things are getting more difficult. I don't know the exact details for 1994+. I love it to drive a 1990 car with 1994/1995 engine and stuff. Sounds a bit odd, but everything in holland is odd
I Know a guy that runs a test. only smog Station, so if the correct parts are there, he will look past the rest. I took the Car by today, he was pretty surprised to see what Was under the hood!

Just wanted to mention, you can find a chart on the intraweb about how fuel mixture affects emissions. If HC skyrocket, you'd probably want a little more timing (longer burn time). It increases drasticly below ~12:1, and above 18:1 (for whatever reason). CO is supposed to skyrocket <14.5:1. Less timing if your NOx is too high, which peaks with high cyl temps and ~16:1. BTW a clogged injector (or multiple) can create NOx/HC issues, since the overall mixture is spot-on, but total particles is above limits. BTW last time I went for emissions was 4 years ago. But I still run cats, go figure.
Hey, thats good info. I sometimes have a customer car which barely comes to the desired values. This test is done at 3500rpm. Lambda should be 1 with a CO below 0,3%. Giving extra timing should do the trick! Thanks!

DAMN!!!! That was the info I was looking for, for a long time!!!!! Thanks a million times!!!!!! Mind if I put this on my personal webside just as a reminder for myself? (Very very veeery few visitors. It just for myself.)
