To my knowledge, all of the ignition circuit stuff on the truck is 12V. Only the engine state sensors are 5V.
They are Pro-M 75 lb./hr. I just reached out to them to get the full data on the injectors. I assume I will need to enter all of that at some point.Yeah, wesk can be a little "terse."
Be sure you follow the timing setup, along with entering the transmission voltage values as they describe.
I found their base tune to be a bit lean, both on my stock truck and another truck I tuned from startup. If it gives any issues starting, increase "req fuel" a little at a time (say .2). After that, autotune will do a lot of the work.
Plenty of us here can help, too.
What's your injector size?

This thing came with an "expansion" card but no instructions were given on anything to do to it . Hell I don't even know what it does. I see it has some jumper spots on it but nothing was mentioned in the set up guide.
Our trucks get a VSS signal from the differential. From what I can see that signal passes through something located under the dash and then to the #6 pin on the ECU. Since the Stinger unit doesn't change that pin I am assuming it is already set up to read the same way. However in the Jumper list they mention "Spare VSS" on several slots. All of them just say to reference the "speed input guide" for details. I searched the forum and the flash drive and couldn't find this data. I am not sure if a jumper is required for our trucks or where it goes. I hope not because I installed the ECU last night without one.
Yes sir... that is the card I was referring to. Now that you mention it it makes sense that they would be adding that board to do the extra stuff. Any jumpers required that you can recall?It should run OK with the default injector curves. It'll idle better if you have the exact values.
You mean the little board that's inside the ECU, on top of the main board, right? If so, that's the transmission controller.
I can adjust the tune from my red truck to your injector size and displacement and send it to you as a "Plan B" starting point. It may be closer than the Stinger base file for your combo, and it's already setup for sequential injection and such.
I did get the USB drive. I have searched it manually and even did a file search on each file folder for the key words and can't find anything about the VSS jumpers or the "speed input guide". They have been pretty good about responding so hopefully if someone on here doesn't know they will reply today.Did you not get the USB drive when you bought the kit? There's a huge amount of data on it, but I definitely understand that it can be overwhelming.
Thank you! This looks like what I need. I am guessing there will be a step in the setup that will ask for this.The Pro-M 75# curve is on their web site - https://www.promracing.com/75-lb-hr-fuel-injector-ev1-style-e85-compatible.html
Man you have no idea how happy it makes me to see that one little highlighted statement. I did not want to take that ECU back out to add a jumper.Was just looking through the setup guide. Looks like there's nothing you need to do for the standard VSS. There's also an appendix at the end of the doc that specifies jumpers. I also meant to add there's verbiage in the instructions around MAF kits.

It's in the item titled "PiMPxshiftStartupGuide" in PDF or Word format.Man you have no idea how happy it makes me to see that one little highlighted statement. I did not want to take that ECU back out to add a jumper.
Can I ask what section of the setup guide this was in? I searched for this last night and didn't see it anywhere.
Thank you very much for going to all of this trouble. Sounds like this is just what I need. The FMU came out last weekend. I do still have in place a boost referenced regulator. My compression is around 9.25:1. Until now I used an MSD 6BTM to pull .5 degrees per pound of boost. I was seeing around 15 lbs total boost. I also buy 93 octane and run Klotz octane booster. I have never had an issue with pre-detonation with this setup.
If I understand it correctly. Turning off the authority table for WBEGO correction would prevent the self tune from making automatic fuel corrections based on wide band inputs? Just trying to get my head around this new world of "tuning speech".
Wow..... I got a lot to learn...
Thank you guys for all of this support.
