Just checking to see I couldn't find any reference to a pin that is used unless I just didn't see it thanks for your help David.

I am little unclear on how user definable the Color CAN display is. Can you display any of the logger channels in either text or graphical form? AT what point does Jason need to actually program it at the shop? I want a screen format like shown below, but with Lambda1 and Lambda2 on the top...

My car cranks, but it will just not start. It's getting fuel and spark, it'd kind of sputter once in a while but it won't start. I toss in the stock ecu and it fires consistently it would run like shit but it'd actually start. Would a "bad" base map cause it not to start. My engine set-up is a...

Here are the steps I took to update my V2SQ firmware to the latest V3 AAEABA firmware. Please note, I use kpa and desired EQ units. I find that it works best to keep units in kpa and desired EQ while doing the conversion. After I am all done, I then switch units to PSI and AFR just to be sure...

I just wired up my Can Display tonight, it a fresh install I haven't started the vehicle yet, just wiring everything up first. Whats this error sign that pops up on my can Display mean?

I'm looking for an ECU for a GTE motor that can: -Give the ability to program boost limit depending on selected gear -Give the driver an on-the-fly rotary adjustment to select pre-set definable boost maps -Incorporate traction control -Give the driver an on-the-fly rotary adjustment on the...

i cant reach larry last days but want drive ! Props: Check engine (oil press not current for now) Maybe i boost and some other probs because of it? i will fix it later this weekend hope somebody can help with short words i send larry the map hope he can send the corrected map ADC Exhaust...

edit: nm , i figured it out i think , at least output voltage from the sensor with 5V in Voltage out = ((sensor resistance/ (sensor resistance + pullup resistance)*Voltage In)) i think 0 ADC = 0V, and 1023 = 5V in a linear fashion, but I am not sure about this, becuase that seems WAY...

Hello all I was long time reader of drag racing and dyno tuning sections on Supraforums, today posting my first question. Had my v1 AEM for nearly 9 years, sick and tired of this box, seems like ProEFI 128 is what I need. Especially like fault/protection features, looks like it will be nearly...

Hi, I’m about to order some sensors for my Proefi install and I was looking for some recommendation as what sensors to get. Here are a few questions. 1) I'll be running NOS, and so far I have narrow it down to using a 1600 PSI bottle pressure sensor; will I be alright using this sensor or...

Hi, I am trying to get my drive by wire working. I've setup the two TPS inputs and two APP inputs. I've tried using the H1,H2,and H3 bridge for the motor output however there is no activity going on when I depress the throttle. I have all channels connected to my scope to look for anything and...

Is there different data stored in the srz vs the xcal files? I know you are merging the 2, but it seems that the Xcal has all the values, so what actually is stored in the SRZ? For instance, when you updated the fault actions, do you do that in a SRZ file or in an Xcal? My overboost protection...

I just installed my pro-efi 128, and the data-logger isn't connecting it is saying "Unable to connect to online ECU, please ensure power is on. Weird, tried that a billion times never worked. Tried trouble shooting to find the problem, and it seems the main relay connected to my ecu doesn't click,...

I set it to psi and I see a current psi number displayed in live read when I switched from kpa. Two items: 1. The digital needle gauge scale is annoying in that it goes from 0 to 38 to 76, is that based of a base setting on the pro-efi? It would be nice to be more like 0 20 40 or something........

So Motec has done it again, taken a 300$ product and jacked it up 10x. It's HD and it overlays simulated gauges fed data through the CAN cable. The very simple solution for us ProEFI users requires nothing more than some software. If someone (Jason) can make a program the reads a data log...

What is the difference between the items in the drop down below? Currently I have my faults set to "enable." However I learned that it will flash the MIL while it happens but the code will disappear shortly after and you will have no idea what it was. I want the code to stay stored on my LCD...

What is the difference between Please explain the differnce between "O2 error %" and "O2 Feedback Multiplier A." Any input is appreciated it. Thanks!

I purchased a newer style flex fuel sensor (pic in link below) and I'm having trouble connecting the plug with the ProEFI pigtail. The pigtail connector is the pink/purple/white one and it seems like something is just a small fraction off. The latch on the proefi connecter appears to be in line,...

Ok so I am in the works of of installing my PRO EFI and it seems all wiring for the trac button is cut out of my car or deleted. So I am ordering a new trac button which 97 and up are what is available. I will also be buying the backside plug with pig tails or wiring. My question(s) is I am...

To control your auxiliary fans, both pusher and puller you need to connect one output of the ProEfi to the Engine coolant temperature sensor. The sensor is located on the bottom of the radiator. You can cut or de-pin the red with blue stripe wire and attach it to an input on your ecu. ...

Just wondering if there is any chance ProEfi was thinking about developing a platform/software that would allow read out to a tablet such as the Galaxy S7. I was just talking with a friend who has the software working on his LS1 powered car using the Torque App on the Galaxy S7 and I have to say I...

My personal laptop is a Mac . . . I'm assuming ProEFI software doesn't work on macs. . Ideally, I'd like to just go pickup a little netbook or similar to have for the car. For the life of me, I can't find any minimum specs or operating system requirements for the ProEFI software. . can anyoen...

Hi, I have a ProEFI that has been tuned for c16. I moved and am now pretty far away from my old tuner. I upgraded my fuel system and want to switch to e85. What do I need to do to the ProEFI to run e85? Is a retune necessary? What's a ballpark cost I should expect for that, if needed?

What is the purpose of the analog outputs on the ProEFI 128? Are they programmable 0-5V outputs that can be used for various parameters? Like if I wanted to have 0-5V analog outputs for the a/f ratio for example or for fuel pressure, etc.

I feel this hasn't yet been covered?? I noticed that when you buy fan setup from PHR it comes with ecu and whatnot I'm guessing to control speed of the fans in coordination with the sensors?? Is this still needed with ProEFI??

I was wondering if it is possible to set up a scramble boost button with proefi? Im thinking a steering wheel button to scramble up to i-boost setting 5 or a preset boost number. Something like that. Can I make this happen?

Larry or Reid, My can gauge (52mm round) seems to have an issue. It will not scroll through the menu. After doing some troubleshooting I have found that if I bend the wiring (gauge side) at the connector the screen will flicker, flash, and sometimes just plain go out. I have contacted ProEFI about...

I just wanted to verify that when you guys go ONLINE and change the time that the fuel pump primes, it actually changes the duration. I hooked my primary fuel pump up to a relay that is triggered by Primary Fuel Pump pin (lsd5). But when i turn the ignition on, the pump primes for a long time...
