Who is throwing a code 43 with hondata?
I've been throwing the code since my car has been tuned. but now with more frequency and part throttle is doggin it seems. I can't tell if it's the bosch o2 sensor taking a dump or if it's because part throttle is tuned too rich. My plugs are also turning black. I think I might try an OEM o2 and if that doesn't work it could be in the tuning I guess. The car didn't throw any codes before hondata with the same o2. Any of you throwing the code? Could be time to change my plugs too maybe. Thanks.

What is your static fuel pressure? And which orifice did you use in your AEM fpr?

yes. I have an bosch as well and my car constantly runs rich even after tuning. used an OEM unit and everythjing is gravy. also i had my fuel pressure at 38. turned it down just a tad.
I used to blow huge clouds of black smoke and I coundn't figure out why, as the Bosch was new. Black fouled plugs were the norm and black spaater out the exhaust was common.
EDIT: I also tried NTK O2 sensors. crap as well
OEM is the ONLY way to go.
when i went back to OEM the pugs cleamed themselves up and no more smoke also popping is gone.

Cool, thanks for the info I'm leaving black clouds everywhere. I don't remember it bogging this much after tuning so it has to be the o2 taking a dump or something. I have an OEM on the way and will pop it in and see what happens. I'm still in the 90 day warranty for the bosch but who knows if they will take it back or not.

Re: (Turbo E 604)
What a coincidence,
I just got my car tuned about 2 weeks ago, and it's doing the same thing, it's thrown a code 43 about 5 or 6 times, a little stumble at 3K occasionally, and going into open loop for no reason while cruising at 60 to 80 mph. We are going to do some highway tuning with the wideband attached to see if we can shed some light on this. I suspected the O2, but I never got a code 43 with my previous setup (vafc and 440s).....I don't want to spend the $200 for a new one from Honda. Does anyone know if the secondary o2 is the same part as the primary...since I have one laying around that's barely been used..

My cel will come on within 5 minutes of cruising. I made sure after tuning that they switched it back to closed loop. Also when taking off in first if I put the pedal like a little under half way down, it just bogs until it finally "kicks in" followed by a black cloud when I go to WOT. It wasn't like this right after tuning. o2 comes today so I'll let you guys know.
You should be able to find a used 4 wire oem o2 for around $50-$60 boost psycho.

Re: (5thgencivic)
It worked! No more CEL with the OEM o2. Car still bogs a bit, but no where near as bad. Part throttle needs tuning, but it doesn't bother me the way it is

Re: Who is throwing a code 43 with hondata? (bluep3)
hehe, I still need to get this rom updated to the newest hondata version to see if it takes out the hesitation at 10in of vacuum above 2600rpm That annoys me more than some bogging.

Do you think that the new O2 is a temporary fix though, running rich should contaminate the new one as well, I would think, unless the O2 is really at the root of all this. The only reason I'm confused about it is that I never got the code before going to Hondata, and my car ran really rich with the old setup..

Hmm, not sure. I will soon find out. However, I remember throwing the code like 2 days after installing the hondata and getting the car tuned. The hondata might magnify things like that since the o2 wasn't oem. Not bashing hondata at all. Hard to say I guess.
egturbo, code 43 also is the code for fuel supply system. The Helms manual has good troubleshooting procedures.
I'm off to autozone to get my $87.99 back. Made the 90 day warranty deadline by 10 days

Re: Who is throwing a code 43 with hondata? (5thgencivic)
Well, I have resolved my code 43 issue, it was indeed the O2 sensor. I just used my secondary sensor that was sitting in my toolbox (since I now have an obd1 ECU, I had no use for the secondary sensor).
the result: no more code 43. the vehicle stays in closed loop and EGTs are back to normal at cruising and idle.
