Dunning-Kruger is a bidirectional effect, btw, and it's easy to be caught on either end of it, for exactly the same reason. In this post I might achieve both ends at once, but WTF. For $250 you can get a USB device to make your laptop an oscilloscope with logic analyzer. It would have given...

Good news. The gauge is not working, will replace. Strange that resistance test checked out fine, but pulled the sensor and it maxed out the gauge at room temperature. Got your post hvyman, don't doubt you, but I'll try extending the neck of the coolant reservoir, test the radiator cap, and...

I forgot to mention that my coolant reservoir was relocated slightly more towards the right and is mounted maybe 2cm lower than stock position when i put in a large intercooler. I wonder if that is giving some spillage from the overflow tubes. If so I just have overheating or gauge issues and...

I'm a convert. Even if it turns out to be okay, it was totally not worth the aggravation of wondering if it's okay. I have a new one on order, and I'm even thinking of swapping for the old one anyway just to eliminate one source of uncertainty in the future.

I checked that sensor over and over with resistance at different temps, got a new one, pulled an old one known good from a donor car, but I will do one step more. This time I'm going to remove it, leave it connected, and test the whole sensor/guage system with a cup of boiling water. That will...

I block tested mine: negative. I do have a cheap radiator cap. I will be testing the thermostat, upgrading the radiator cap to a better brand, checking the overflow lines for clogs. If I don't find anything I will do static and dynamic compression, and do more testing on the dash guages.

Block test was negative. actual Radiator coolant temp at the pressure cap after idling 20 min was 170 degrees with a separate thermometer. The dash guage was off the scale. I'm checking the thermostat tomorrow. Will do compression and leakdown anyway to be sure. Since this thread is...

same exact symptoms, same situation. Did you do those tests? After reading this, i'm going to do the same tests on mine.

Thanks for your response. This isn't sitting well with me and i'm giving it a week or two before tearing into the job. 1) I did compression test it and all were within specs, though some a bit lower than others. Sadly, I can't find my data sheet to say what cylinders were relatively lower...

Actually not so slowly overheating. Got the right temperature sensor in. I was surprised that it overheats within 1-2 minutes of starting the engine, just sitting at idle. I didn't even know that was physically possible. I wonder if that's the water temp or just the temp of trapped gasses in...

Actually more about when it is necessary to refinish deck and head - sorry about the mistaken title for the thread. Barely have driven the car since I did a full rebuild on 7m Turbo, redecked, head done professionally, but reused my titan motorsports MHG with the copper sealant spray, torqued...

Thanks for clarifying the goal of controlling dwell time. Of course that needs replacement of the internal circuit.

Yeah, this is the fun part. I have had trouble finding a tuner with experience with this type of car in Michigan, but there is enough published and online that I'm not worried. It's nice to have a piggyback unit that starts from the stock tuning, and a car to tune that has some much information...

Updated: Engine is working with EMU - updated wiring diagram and jumper settings. I have all the inputs and outputs on the EMU verified by DVM or oscilloscope except the IgF modification circuit. When I bypass the added circuit and connect IgF from Ignitor to TCCS ECU normally, my care is...

Just an idea for the group: Why not use three 7m-GTE ignitors wired to a piggy back with ignition function like Emanage Ultimate? Just preset each to trigger one channel each time by sending IgDA to one, IgDB to the other, and and both to the third ignitor, then use different EMU ignition...
