24v duster - input? :D

[Ondonti]

nope, only reason the original ECU was in the car previously was for the speedometer and due to the fact I hadn't had the available downtime to re-wire the car. straight MS and body wiring only now.

What wideband are you running that has a lot of wires? the LC-1 only has like 5 now... I have a few grounds, 2 outputs, +12v and the serial connections... In this install version, I have the LC-1 under the MS mount and essentially permanently wired in with the LED and calibration switch.

Any reason you didn't use a spare output on the MS to trigger your Meth injection?

I don't even have an output wired up for fan so I have to manually switch that on/off.
Zeitronix has 2 egt wires, 3 map sensor wires, 2 grounds, 1 power, 3 output wires, and I maybe others that you can use for their alarms setup.
I like the progressive nature of the alky controller that I have instead of on/off. I don't know if there is a real purpose to that when you have megasquirt. I don't know how accurate it would be for fuel to be pulled back right as the alky controller turned on 34 gallons per hour.

Updates are now going on the project log thread for all those interested...

[Shadow24]

So, in my wiring work, I have discovered I am missing a couple connectors I need. If anyone has spares' I'd be grateful and can probably throw a few $$ your way.


1) Manual trans speed sensor connector (later 3-pin, not SDS sensor)
2) Manual trans backup switch connector
3) firewall blanking grommet near the trans tunnel

new update on project log thread (rust carnage included!)

[Shadow24]

Another update in the project log - nearing the point of attempting to start the car for the first time in 3 years!

[Ondonti]

New fuel?

[Shadow24]

brand new, with stabil. Tank was bone dry previously. (learned better from last time lol)

[Sundance 6g72]

Safe to say my parts worked out for you?

Safe to say my parts worked out for you?

The sensor was from a different type of transmission, but I needed the gear so it's all good.

New update on the project log, engine fired up tonight briefly, still a lot to do though.

[Shadow24]

More updates in the project log, getting closer!

[Shadow24]

Even closer now, update in project log

Update - Lucy is now prowling the streets again! Over the weekend I returned to Ohio and got the last touches done for Lucy to be put back on the road. This was mainly an alignment (Firestone Lifetime Alignment FTW ) and ensuring the A/C was working. We were able to get everything hooked up for A/C and it took a charge well. I consider this quite a success as Lucy is using a 2001 Mitsu compressor coupled to the factory 1994 shadow condenser, receiver/dryer and evaporator system. Unfortunately while charging the system, the low pressure schraeder valve is no longer fully sealing. The valve cover appeared to stop or heavily mitigate the leak, but I suspect I need to replace the valve and re-charge to permanently keep the A/C working.


We also ran into issues on the 900 mile drive from Ohio back to Tulsa. The fuel gauge is not accurate (I suspect a wiring/resistance issue) and we ran out of fuel once. Luckily a good Samaritan stopped and I was able to get a ride to pick up a couple gallons of fuel to limp Lucy to the gas station a couple miles away. Lucy is not making anywhere near the power she did in the previous iteration, and her fuel mileage is an astonishingly low 19 to 20 MPG. I believe I have a fuel supply issue as she was running lean and a good 15* to 25* hotter than usual. I used to never see coolant temps over 200*, but we were pushing 220* cruising at 70 on the highway. First thing to check I think, will be the fuel filter. Hopefully it is just a clogged up element and not a bad fuel pump or other issues.

[Shadow24]

Well, I bypassed the Jegs filter I had installed and it did fix a good bit of the fuel starvation issue. Still not back to 100% of pre-swap power, but it at least drives a heck of a lot better. I believe the wbo2 and the TPS on the 65mm throttle are now what are giving me issues. the TPS keeps changing so my accel enrich is all over the place and the o2 keeps conking out on me, requiring a reset to start working again.

[Shadow24]

So...I figured out one reason why I haven't had full power on Lucy....Some idiot forgot to properly secure the throttle cable! The sheath had pulled toward the throttle enough that matting the petal only netted about 1/4 to 1/3 throttle angle. I think I will be building a proper bracket this time instead of the pseudo-bracket clamp thing I used on Lucy 1 (or the zip-ties that are currently holding it in place). It still feels like I am not running right above 5000rpm, but once I get the throttle fixed, fuel filter replaced, fuel pressure verified and o2 sensor rectified, I should be able to see what's truly going on with the AFRs.

[Shadow24]

So I got a little more work done on Lucy today. I made up and installed a throttle bracket to keep the throttle from moving around on me. I also located the major exhaust leak (about 1" from the o2 sensor). The gasket between the collector an the catalytic converter was shot and 2 of 3 mounting bolts were MIA. replaced the gasket and got new bolts with lock washers to seal up the exhaust system. I still have backfires occasionally going between deaccel and tipin, but hopefully with the leak fixed, I can see if the AFRs were reading off and correct the issue. I suspect a possible over-fuel issue due to the exhaust leak skewing the sensor readings. I also STILL haven't upgraded to the latest MS-II/E code, yet. That is definitely on the list due to the massive number of refinements from my current code variant (3.2.1) to the current 3.3.2 or so.


I haven't had time to diagnose the A/C leak, (I suspect the ONE hose-clamp connection in the system slipped due to high pressure) but I did replace the one valve core that was a potential leak. Hopefully I can get the system vacuumed down and re-filled soon (A/C was nice to have in 90*+ weather!)

[Ondonti]

Nice to see you have a custom bracket holding your throttle cable now. Spiritman needs to do something about his!

[Sundance 6g72]

My 3000gt is missing the throttle bracket (cable was held in by zipties) :facepalm:

[Shadow24]

Well, another wrench in the works. Lost both the power steering and alternator belts, resulting in the timing belt jumping time again. I haven't been able to test to ensure valves aren't bent, but I'm hopeful. The crank pulley is only 2 teeth off, which is 30 crank degrees. The serpentine belts tore up the lower timing cover so I have to get a replacement. Upon dis-assembly, it appears my tensioner is shot as well as it had loose play in it. Additionally, the roll pin indexing the crank pulley to the crank sheered and had to be drilled out again. I'm also looking at replacing the crank sprocket as I have drilled out that roll pin twice before and it is showing signs of wear from the re-drilling. I just have to scrounge up the funds for a timing belt kit...


In other news, the issue with the A/C going out was the pressure relief valve blowing on the compressor (exceeding 500psi). It looks like the rest of the system is OK, but I think the Dodge high pressure switch is not functioning. I am going to see if I can adjust the wiring to tie the multi-switch on the compressor into the circuit instead to stave off an over-pressure situation again.

[Ondonti]

serp tensioner shot or timing belt?
