No problem. A check valve lowers flow at all pressures (I used to work in the valve engineering industry) but it may not be enough to cause what you are seeing. I ran my wires from the relay and...

What pump are you using, the 255 external? I have built several Camaro aux pump setups, I run a 2psi hobbs just to make sure it comes on early enough, along with an indicator LED so I know when it...
Not out of pump, likely out of injector. When injector DC gets close to 100%, they are basically open all the time, so pump cant build pressure.
Yep. I set mine to 14.5 because the 5th gens are set to 12.5 from the factory, so it reduces voltage, but it cannot increase it. So 14.5 is about what the alternator can put out, so going higher than...
The injector tables wont match, in the FSCM they dont go about 63 lb/hr. Just set your desired pressure to 65 psi in the FSCM.
Yes, the fuel tank pressure sensor is how the FPCM gets pressure in a stock system. It works for logging data for sure. I set the FPCM to not fitted in a retrofit applucation, and have not had an...
His truck doesnt have a fpcm from the factory, he is just trying to add one in an E67 retrofit application. I have added the sensors without the fpcm in refrofit applications with the E38 and E67, it...
Not where i can get to it on my phone currently. I need the diagram, it is one of the 5v reference pins and low ref pins.
yes, as long as sensor is wired in, the pcm will use IFR table to compensate for pressure spikes or dips. If you put the sensor near the fuel rail, it works better than back by the tank like the...
Connector C1, pin 48 on the PCM is the fuel pressure signal input. I dont know what you are trying to do, but if you are running a return regulator, there is no reason to run the pump through the...
You dont need to do all that. The FPCM wont do anything hooked to a return style setup, as your pump will be running 100% DC anyway. The E67 PCM has the input for the pressure sender, the FPCM gets...
To answer your concern, the Livernois dual pump setup is a CTS-V module with an adapter for the Camaro venturi pump pickup tube and internal wiring for the fuel evel sensor changed to work in the...
Tried to read a 2010 and 2011 SS with stock FPCMs, wouldnt work with the beta I downloaded today.
Now that I know it isnt an actual read, it is fine. But I already know my FSCM isnt a stock file for my car, because I installed one that was flashed with a ZL1 file with TIS2Web. But it wont let me...
I guess that is what I was getting at, it gives me a read option for the FSCM. When I did that for my car, it won't let me edit my file. Maybe that is why it won't let me edit my file, because I have...
Several of the other tables are different, i.e. the duty cycle tables. If I can't read the file from the car, how am I supposed to edit it and flash the calibration? It gives me the option when I...
Yes, I've tried to read my car, which is an SS with a ZL1 FPCM, which is just a blank new FPCM I got from GM then used a ZL1 VIN to pull the calibration from Tech2Web and flashed.
I get an error...
With just a quick look, a section of your IAT sensor curve is off where I highlighted. Top is correct. 67641
It also looks like some of your injector data is wrong compared to ZL1 injectors,...
I'm in the Birmingham area during the week, and do tuning on the side in the evenings. Haven't been on the forum in a while.
I got 3.0 working today without freezing finally. Had to switch to my other, older laptop that has an AMD A4 processor and Windows 7. I had been using it with 2.24 for logging to get me by until...
Thanks Ed! Being a customer of your training program has payed off numerous times, and this is just another example!
Thanks Ed. Keith is still working on my issue, has been since yesterday, still not fixed. I don't generally get an actual error, it just stops logging either the WB channel or all channels, which...
Keith-
Sent the email.
I have already done that twice this week, this afternoon was the last one. I will do it again.
I do appreciate them updating every day, but my issue has been going on all week with minimal communication. I have made repeated requests for a copy of 2.24 to be sent to me so that I can reinstall...
