well stupid question.. does the knock sensor override your prgrammed ecu? your engine may have ended up running way to lean and then it is trying to compensate?

just a thought from a person who really has no idea how your ecu setup works h:

 

they are overrated, but only to a certain degree... I would much rather run an ems over the others though b/c most of them have many more flaws as apposed to an ems, I know I've seen more ecu upgrades screw up b4 an ems, assuming both are set up properly... but i'm not taking sides either b/c i agree to disagree, because one is also fifty million times cheaper to get than the other. Each has it's pros and cons, and i'm not even gonna say one outweighs the other...

 

I was thinking about that, but the only effect the knock sensor would have on the setup would be throwing off the ignition timing. IntegraType-R ran that by me last night and I totally agree, but it has nothing to do with the AFR's.

I am still stumped because it ran perfectly one day when I tuned it and then the next day, it went rich everywhere in the powerband and hasn't been normal since. I have even subtracted 20% fuel from the first three columns and it doesn't even affect the AFR. :dunno:

If I had the money, EMS is a great choice, especially for an OBD2 car because you don't need a conversion harness. The problem with the EMS for me is that I like to do things myself and tuning it would be out of my league. I could probably get the AFR's pretty good, but to make it run like a factory turbocharged car would be very difficult.

 

we'll get it. ..

 

just out of curiosity, have you reset the ecu at all through this whole matter, if you reset the ecu, and still have this same problem, there is a single wire you can cut in your ecu in-order to take it back to the STOCK map. if you dont know about it, look it up on ff-squad or something of the like. Cut that wire and if it is still rich as a mofo, get rid of the ecu and get a new one that is not murdered yet. Or maybe buy a ecu, p28 or the like, and pay 60 bucks from a hondata dealer, for a open chipped ecu, and then, you will have an acu that is for sure good to go that has been tested and benchmarked from hondata.

 

Yeah, I know which wire you are talking about. The problem is that I am running a wideband w/o a heater, so the ECU will be spewing codes at me once I go back to the stock map.

I am going to test my map with GSSR's P28 that he just bought and see if it is a problem with the ECU. I really think that there is a wiring issue if that doesn't work, though. After smog I need to completely rip out the blue box and solder everything up nicely to eliminate any voltage problems at the harness.

 

:werd:

i was looking at them and they offer so many options it's kind of pointless unless you really have the time and mnoney to put into research and teching yourself how things work.

alas, i'm going to be looking for one when i turbo, i like things fine tuned

 

Thread Revival!!!!

Anyways, the problem wasn't with the program or my crappy tuning ability, but rather the wideband itself. I got in touch with Zeitronix about the problem and they walked me through some trouble shooting to figure out what the problem was and they speculated that the O2 sensor harness was bad, but my buddy ordered another one and it was doing the same thing on his car.

Finally I convinced Zeitronix to let me send it in for repair and they said that something in the controller malfunctioned and it was a 1:100000 odd that it happened. So they repaired it, free of charge and sent it back to me. I plan to tune both mine and my buddy's turbo GSR this weekend, so hopefully it works.

But anyway, Zeitronix has the best customer service I have ever encountered. The emails were responded to within 24 hours, the repair took two days, shipment took 1 day and they even emailed me when UPS delivered it to my door.

 

best service i've ever encoutered was for my dad's minimed pump (for diabetes) i called them up cause he was pissed it was busted... but i called them and they were like, it's broken? alright, we'll get one there tommorrow.. sure enough there it was at the door the next day, no questions asked
