  1. Your cat would be colder from all the unburnt fuel, not hotter if your ignition system wasn't keeping up.

    The factory ignition system is more than capable, Honda's engineers built it to happily run for 300,000km - it'll run a V8 and still have enough spark left over to start a BBQ... 

    Post up what you've got in the 'Ignition Main' section of your setup here.

    Have you checked your base timing?

    Awesome !.....now I'm more a happy camper with explanations being sent from what you saw in the cal file and log ,ok  progressing when I increase master fuel because I too thought fueling was an issue ,there was no combustion happening but the strong smell of fuel was evident with every exhaust stroke exiting the exhaust 

    That is correct , but what is confusing which bought me to this point is that it will  not do this all the time and (2) on a random crank it will  stumble on and fall out , this will happen two, three times and won't happen again ,not even the backfire , and another time  a few stumbles and then a massive backfire . 

    Have you tried adding/subtracting 360 degrees from the trigger offset?

    Could it be sparking on the exhaust stroke?

    This would be my thought, if it's sparking, the timing is set and has fuel I'd pick it's trying to fire 360 degrees out of phase.

    I'd hazard it's one of the most common things that folk do...

  4. I have a G4+ Plugin ECU w/CAN-Lambda connected via a NZEFI CAN cable that is not connecting all the time, sometimes it'll be fine, others it's not, I have it wired to power up at the same time as the ECU to minimise the chance of a timeout event for device detection, and when it's not connected it still detects it in the PCLink software.

    Any ideas?

  5. Had a Seal Autocross yesterday, we developed a issue where halfway through the course the car wouldn't go over 3000rpm without hesitating and backfiring, it would come right after the run, and wouldn't manifest itself until the same point on the next run.

    At the end of the day when we got home I went to pull the logs from the ecu to see if I could get some clues as to its cause but my logging memory was empty aside from a four minute log from what it recorded when I took the car off the trailer and put it in the garage.

    Any ideas what would cause this?, ecu logging is set to run at 10hz over 200rpm, with no IO conditions, even the log from when we unloaded the car at the track and warmed it up was absent.

    However as a general comment the Link stuff seems to be fairly error tolerant and I think most of those standards are very conservative, I have never had any drama with longer stubs so Im pretty sure you would get away with the "double adapter" and a 1.0 or 1.5m stub as you planned.  I just cant guarantee it as I usually try to follow the rules so dont have enough experience at breaking the rules... 

    Canbus stubs can be quite a bit longer, most modern cars are a veritable spiders web of the things! 

  7. I'm just running mine off its battery for the moment but will eventually run it through a OTG setup, I'm just going to make my own - a OTG cable is nothing special, it's 4 wires, two for data, two for power with the power negative tied into the sensing pin at the device end.

    It means I can use some decent cable that will stand up to vibration better than one made in a factory for 5c.

  8. The first order of business is to test the components you have, there's no point in getting out the Visa card until you know whether something actually needs replacing.

    What is the Wideband/Lambda value doing immediately prior to when the issue presents itself?

    There is no "long term fuel trim" type functionality.  You typically want your fuel map to be tuned properly first an only rely on closed loop to make small corrections.  If you are looking for an aid to tune the fuel table then look at the mixture map and "quick trim" functions which allow you to correct the fuel map from logs.

    As far as tuning goes, what functional differences are there between using the mixture map and the quick trim feature?

  10. There's not much point in even looking at what your boost controller is showing until you sort out where the misfire is coming from, test all the ignition components and then work from there, have you determined whether it is one specific cylinder that is misfiring?
