Having an issue with the MS3 providing ground for my fuel pump relay

I did voltage checks everything is getting power, but my ground provided by the ECU isn’t working so no pumping.

It’s wired into a toggle sw. relay can anyone think of an issue if it just comes on with the key and stays on? I can shut it off with the switch.

Thanks Ben

I don't see why it would be a problem. Unless you crash! Maybe you could power it with an oil pressure switch if your concerned about that. But especially for testing I don't see why it would hurt. You do have a return system right?

[Chip Birks]

Are you trying the test mode when attempting to fire the pump? Or just key on?

[Schweg]

Buguy- I’m worried about the crashing part more then anything. Not that I’m planing to but I’d like to be safe.

Chip- I haven’t run test mode. Just key on. I’m still trying to figure out TS. I haven’t even been able to put in my sequential settings.

Fuel pump is good after back probing.

Now on to software issues!

Fell like I’m missing where my cam sensor information goes? I don’t see it under ignition or fuel settings?

Also not seeing the bbdc setting for the crank.

Trying to set up full sequential.

UPDATE:

So after talking to Mario and getting some advice I'm going Batch fired and wasted spark just to get going.

Got my settings in TS and no major errors. Entered test mode and checked my injectors.

Tried testing my spark but got nothing. Using LS2 coils. I'll check wiring again tomorrow for coils. Should have a first run video this weekend for sure.

Need to attach some couplers when they get in and swap a throttle cable. Also LETS GO BLUES!!!

Sounds like a good plan. Get it where you know it's working then tackle sequential when you can change things one at a time in case something weird happens.

Update:

Mileage: 1.5

It runs! Drove it around the block!

Couldn’t get the idle down it was hanging around 2500 rpm.

Saw 2 psi of boost then it falls on it face!

I have a log but I’m not sure exactly what settings are affecting what. Anyone want to take a look?

Schweg, I would turn the beveled cut on the exhaust system around. As you move the air is going to want to go up the exhaust pipe because of the direction the bevel faces. You want the diagonal opening facing to the rear of the car.

Lee,

Thanks I will, i need to add a muffler in so I can use this thing more often then the middle of the day. I’ll swap it around once that goes on.

You will need to add fuel once it goes on boost.....Especially if you aren't injecting Water/Alcohol.
Post a screen shot of your fuel table and a screen shot of the log where it falls on it's face.
If you are logging....you can mark the log by hitting the spacebar...that will create a line you can find when right clicking the log to find the marked area for quick reference.
You can then see what is happening and fix it.
Most likely it needs a bunch of fuel to compensate for the boost.
Timing will be ok until 6.0 lbs as long as the IAT's aren't going way up. Just make sure your timing is around 32-30 degrees BTDC after 110 plus kpa and ramp down to 26-24 after that.
If above 10 lbs boost and no IAT cooling capability you might need to be down to 18 degrees timing to stay safe.

Clone,

Have not spent any time on these yet. Also having an idle issue I need to address. Thinking that my CLT never got high enough to kick off enrichment.

Also I guess I never actually got boost according to my data log. But.... hopefully soon!

Thanks for taking a look.

Bummer that your having troubles, but it has to feel good to have it start, run, and move under it's own power! That's exciting!

Couple things I see.....
You need to calibrate your TPS.
It's showing -7.1 and plus 101.3. Go into the calibration tab and fix that....it's easy to do.

Your VE table is all the way to 400 kpa???
That's a little over kill. I would do a "Save AS" and name the file some name with a "bak" in it to designate a backup file.
You then want ot go and remap your VE table to something realistic to give you better resolution for tuning.
Set your max kpa to 200-250...it will be a while before you get to that.
Rescale all your fuel cells. Better yet set up your AFR targets and your Lambda delay and let "Autotune" do the work for you.
I run Autotune on the easy setting and it fixes my fuel map pretty quickly.
The hardest part is figuring out what afr your engine likes at what load and rpm.....that just takes a little trial and error and you will get used to it after some time in the seat.

Congrats on a runner!!

That looks like most certainly like sync loss on the RPM signal. Did you install the 10k resistor on the VR wires? It will be needed.
