    Oh, I forgot to add that an quicker way to reach me instead of PMS (I've not been checking in that often) is to hit me at superlen*hellfireproducts.com. The webpage is just a hello world, but the...

    Time for an update & some pics. Don't get too excited, I'm still mucking about with the AFM and flow bench pulling some numbers, but it's somewhat interesting so here are the pics. The first is my 3d...

    Hi All,

    Sorry for the slow/non-existant updates. I've been playing with the new baby & friend/family projects have been needing my attention when I did have some free time this summer. I had...

    Captain,

    Bob's definitely got a spring loose. :) However, his AFM offset is primarily because the wiper is mechanically shifted on the carbon track so even at rest it can't show a small enough...

    Undefined,

    What you called the transistor unit is in fact the ECU. (Drivers side kickplate) What Datsun calls the ignition module, but is could be called the transistor module, is much smaller and...

    Scary stuff!

    You're right on the return line. If everything is working properly shouldn't have high pressure on it. Having said that, I would do the same thing you did, use FI rated hose on it...

    sscanf

    I think once you dig in to it, you'll find the drift is actually in the multivibrator stage, not in the conditioning circuit from the CLT sensor. Not the entire multivibrator just the...

    Just a quick update.

    We have finally settled into a routine with the new baby & I can slice up some time for HellFire. :) I began flow testing the AFMs I have today.

    Captain,

    No that was with his extra AFM. I have his original AFM that's out of whack. Tomorrow it goes on the flow bench and I'm going to pull the numbers we spoke of the other day. I've already...

    Everyone,

    Thanks for the accolades for the princess. :) I'm already dreading the years 2028-2034. And thanks Blue for noticing my pedicure. LOL Note, also I'm working in my PJs quite a bit lately....

    Greg,

    It sounds like you're back up and going. (For the record, after reading this post & BEFORE you did your last round of cleaning, I was thinking the same thing Blue said...the WOT pulse...

    Everyone,

    I'm still around, just been preoccupied. Much like the HellFire, her mixture isn't quite right yet, but she's doing better every day. I keep feeding her fuel, she keeps wanting more. :)...

    Zed,

    There are definitely pullups on the INPUT side of the transistor to do exactly as you said....hold the transistor in a known stable state when you aren't firing it. The pullups I noted...

    Zed,Sarah

    There is a weak pullup on the transistor output inside the ECU. That is what keeps the voltage up at 12V when the injectors aren't being energized. I'm not sure why Bosch decided they...

    Thanks for all the well wishers. I'm realizing now that my normal 6hrs/night sleep was a luxury. I miss sleep. :)

    Chas,

    Interesting failure mode for sure...especially for something that is essentially a resistor. I would have put money on open circuit or abnormally high resistance as well.

    Chas,

    I have several AFMS if you need me to pull an air temp sensor for you, just yell. I've never had one off the AFM meter and never heard of one that confirmed failed. Lucky you. :) Nice hack...

    As far as sensors, the big three for poor running (usually rich) are AFM, CLT, & ECU. The IAT, AAR, Cold Start Valve, basically everything else can be removed and/or disconnected and you will still...

    Chas,

    Thanks. The free flow flowrate number is good info to know. As much garbage and rust I had in my tank before cleaning it out, I should really test mine to see where it's at.
