So I have a L28ET that I put into my 240z and I am going to run a supercharger on it. The supercharger needs an oil feed, so I hooked it to the old turbo oil tee that is just before the oil pressure sender. I wanted to make sure that it was working correctly so I left the line disconnected from the tee and cranked the engine, but no oil was comming out. At what RPM should I expect the oil to start being pushed out of that tee? I have the stock pump and everything.

I just set it up from the instructions on the page that Clifton provided. It works great. Thanks alot for sharing that!

O man, that is great. Thanks alot guys!

Im using the MSII code, not MSnS_E. What I was thinking is that since the FIdle is a tepreature related on/off circuit anyway, I could just set the temp that the FIdle is supposed to turn off at for the temp I want to turn the fan on at. Ill let you guys know how it works, Ill be wiring it up later today to tomorrow.

I have a Taurus electic fan that I want to wire to my megasquirt. Im not using the fast idle circuit, so I was thinking that I could take teh FIdle output form the DB37 connector and run it to a normaly closed relay that would control the fan. That way I could set the FIdle in megatune to whatever temp I want the fan to turn on at. Will that work?

Well, Ive been working on this project off and on since winter and today I finally got her up and running. Still not driving yet, but atleast it idles. My only real question at this point is about the narrow band O2 sensor I have. I know the green and red graph across the bottom of the main screen is to show you if you are running really rich or really lean, but which side is which? When the car starts up its it all the way on the left hand side (only a couple of green circles are lit up) and when I rev the engine it goes about half way up and a bit into the red. I am using mobys fuel map, so I would assume that it should be really rich, atleast thats what ive been told. Also, when I was looking at this reading, the car had not warmed up all the way... or at all really. I didnt was the thermostat to open because I didnt have the radiator attatched at the time. Thanks!

OK, so Im pretty confused here. I just bought a Mr Gasket adjustable FPR for my carb set up. When I blow into the port that says "in" there is no restriction at all. When I blow into the port that says "out" it gets harder to blow through the higher I turn up the pressure. Shouldnt it be the other way around? If there is no restriction on the gas when it goes into the "IN" port, how will that creat pressure?

Why is there a vacuum line going to the stock FPRs? I understand that RRFPRs need it so it can increase pressure under boost, but why would the stock ones need it? Isnt there job to provide constant fuel pressure? I can see that on the NA FPR maybe it would be used to open and shut a valve inside, but on the Turbo FPR it would need to be on in both pressure and vacuum states. I was just hoping someone could clear that up for me, thanks. -Warren

Just a little FYI everyone: your car will probably NOT start if your crank timing is 70 degrees advanced....

Prox: Yea, I got it saved in my AI log. Moby: I dont have a setup that can open that file either, but thats ok, I think that I will be able to get it with the settings Prox gave me. This has got to be the most frusturating part of the install, I can get the car to fire a couple of times and spudder a bit, but just not quite enough to get it to start up... sooo close.....

well, what I think ill eventually do is use the EDIS coil pack and fire it with the new MS router board and use an optical trigger for crank angle sensing. the points are just something to get me up and running for now

My EDIS setup was abandon a few days ago in favor of points and MS-II firing the coil directly. Thanks though.

I have an L28 with 440cc injectors. I was wondering if someone with a similar setup could post their cranking pules width settings. Thanks, Warren

awesome. thanks guys!

Anyone know which way the fuel is supposed to go on one of these? http://www.arizonazcar.com/injpump.jpg Towards the electrical contacts or away?

After further testing it seems the MS board itself is working great. The issue seems to be in my EDIS wireing...

What I have: V3 board, MS-II, EDIS-6 ignition. So in my previous posts I have mentioned that originaly I could not get a tach signal into my MS. I basicly pulled some of the wiring out, and remade/repositioned my sensor mount and when I put it all back together it worked. Unfortunatly I then set off to solve my problem with the TPS. Pulled the MS board again, fixed a bad solder point, reinstalled. TPS now works, however the tach signal has disappeared again. I have done LOTS of tests, and here are the results: Voltage between PIP and GND is 12V when disconnected from MS Voltage between PIP and GND is drops to 3.7V when connected to MS Meter reads aprox. 1.2-1.5kHz between PIP and GND when cranking (that translates to about 200-250RPM) I have tested all components referenced in the MS V3 optoin circuit (http://www.megasquirt.info/ms2/v3pcb_3.gif) except my opto-iscolator (U3) and I have double checked continuity between all points on the board with my meter. I am absolutly stumped here. Is it possible that the MS-II chip would have all functions working except the tach input? Also I found it very strange that the voltage between PIP and GND drops to 3.7V when connected to MS. Any ideas at all will be greatly apriciated. I want my car to run really bad! EDIT: I scrubbed my board with Acetone today to make sure I wasnt getting any shorts from excess flux.

and it all works. yay

OK, I think I traced the problem to one section of the board. Attempting to rewire now....

specificly the 240sx TPS

Anyone know what resistance range the TPS is supposed to provide? EDIT: OK, a while back I was trying to fix another problem with my MegaSquirt. During this time my TPS was working like a champ. I was getting frusturated with the problem at hand so I took a minute for the simple pleasure of playing with the gas pedal and watching the MegaTune gauge move up and down (I know, Im an idot). Well, after about a minutes of playing with it the meter just got stuck at about 50%. At first I thought maybe somehow a wire came loose, so I pulled all the old (shody) wiring out and ran some brand new wire with good connections. Nogo. I thought maybe the TPS went bad, which lead me to my original post in this thread. But I figured out what resistance range my TPS is supposed to be putting out, and it tested good. I am 100% sure that it is wired correctly, I have 5v comming out of the MegaSquirt all the way to the TPS and I know the ground has a good connection. It seems that the MS isnt accepting a signal input for some reason. I checked continuity all the way from the TPS to the MS board and there is a solid connection all the way. I tried taking the +5v and running it directly into the signal line and there was no effect at all on the Mega Tune screen. Im really stumped on this one...

Well, I literally ripped everything that had to do with the EDIS out and remade everything, including sensor mounts, LOL.

So I missed the MSA show this year back in april becuase I couldnt get my MS up and running. I was trying to get it running with an EDIS ignition system, but I coulnd get the MS to receive any tach signal. So what did I do? Didnt touch the car for well over a month ofcourse! Well a few days ago I got the Z bug back and went back to work and as of tonight the MS is regestering the incoming tach signal. YAY! Now I just have to figure out what the hell is wrong with my TPS and Im off running!

Awesome! thanks, I will read through it later

I am going to be running supra injectors with my megasquirt. I dont want to bother with the flyback board and PWM settings, so I just wanted to convert the Supra injectors to High Impedance. I have searched around but all that I can find is that I need to put a resistor in series with the injector. So my question is what is considered a high impedance and what type of power handling rating does my resistor need?
