    Thanks. I'll look into it. I have a pretty good tune currently, it's evolved a pretty long ways from the basic generic gen-IV file but I need to get those pesky transients under control. Not bad when...

    Thanks. Since both you and Scott endorsed the obdxpro I ordered the GT. Personally I think the expense is a bit much but if it allows me to tune out the transients it will be worth it. I'm hoping the...

    Yeah I did that and the blue led starts flashing fast to indicate it is trying to connect but it never shows up. I'm pretty sure it is FUBAR at this point. These have gotten pretty expensive, I would...

    It seems my OBD Link has lost it's mind. Blue light flashes but it doesn't seem to send out a signal. Neither my laptop or phone can detect it. Not exactly a robust bluetooth connection there. So......

    Great! I already have that on my laptop, and just installed the latest version. Just have to learn how to use it again. I hope to load my latest tune from HPT and go from there. I'll check out the...

    Thanks for that, I guess I will have to sort out where to find this throttle stomp compensation. Been using the HPT VCM Editor and I have never seen anything like that in that app. Can I assume you...

    '411 Transients

    Anyone here know how to tune transients in the '411 ecm? I've been using HPT and it may be a bit lacking in that area.

    Slowly creeping up on it. It's got this thing right now where it idles down to 800 but then when I start driving it the idle stays up around 1300. I need to sort out what is causing that. I think it...

    OK I'll do that.

    What I'm seeing for AFR Commanded ranges between 13.2 and 13.7 which seems rich to me. My measured AFR is running 12.2 to 13.5 mostly, with an offset generally under 1.5 and this...

    OK thanks. So do I need to zero out the PE tables to work on the rest of the VE table?

    Hey guys. Thought you'd want to know the outcome. To make it short, a self inflicted wound of course. Be careful and methodical when turning off error messages. Turn off the wrong ones and (so I've...

    OK I'll try that tomorrow. Having some fun with the MAP and AFR traces and trying to sort those out which I really need before doing much more but at least maybe I can get the idle steady. The AFR...

    Good idea. That sounds like just the sort of thing that might do the trick. At present the advance is rock steady at idle. I'm not seeing any evidence of misfire and the surge is too consistent and...

    Idle Oscillations

    I have an oscillation cycle that is about 2 seconds long.
    I've made minor and major changes to the idle PID settings to see if the IAC could control it but it may not be capable of it as it is too...

    Good call. Not real sure what exactly that PID was, it was the only MAP channel labeled as 2 bar. However once I activated the SAE and voltage channels I got a better picture of what was going on. I...

    That's part of the oddness. Baro should be somewhere around 99 at 600ft above sea level where I am, though I don't know where to look for that reading (any suggestion?) KOEO the MAP reads zero until...

    I have power to the injectors. The controller is not switching. I will check the power and grounds to the ECM and then recheck the CKP and CMP.
