Which version of TunerPro are you using?

I think you will find the stock tune to be very, very rich.

Guess you need to check the output from your oil level sender.
If it is just an ON/OFF switch you could wire it with a +5v from J2-2 and then configure one of the unused pins (like J2-4 - Fuel Pressure) to act like a switch showing OK with +5 and LOW with 0v.
Are you logging a wide band?

According to the ADX file 0x2C is the packet offset for the TPS sensor. Is the J1-18 pin an input or output? According to the connector diagram I have the J1 connector is an output connector. The J2 connector is listed as the output connector, but J2-20 is shown as Oil Pressure Input so I am not sur...

You can purchase scanning software for the MEFI controller here:

Does your ADX file have an existing channel for a wide band or are you trying to modify an unused input to accept the wide band voltage? I am using an old ScannerPro program, but here is a link to how I modified an unused channel in my ADX to accept a wide band voltage: www.carols62.com/ramjet/wideb...

Innovate LM1.

I realize that this is an old post, but does anyone have a link to the plugin information on the Innovate site?

Which MEFI controller do you have - 4a, 4b, 5, 6 ?

Contact Bob at OBD Diagnostics. If you purchased their software they may furnish the files you need. If your MEFI4b computer is from a GM RamJet 350, Bob may be able to furnish you with the password.

When you say "A copy of ScannerPro comes with an ADX file", do you mean it comes with the one I need or it comes with a generic one? Thanks. As far as I know, when you order the scanning software you get a copy of ScannerPRO and the appropriate ADX file for your MEFI controller. Call OBD Diagnostic...

Thanks for the response. I have the cable pinouts so I am good there. Since all I am interested in is reading data (had an oil pressure switch go out on me this weekend and would have made troubleshooting much easier), where would I get a copy of the older Scannerpro software that works with this E...

I have a Volvo Penta with the MEFI 4b ECU. I would like to read parameters, codes, etc. Not interested in changing anything right now. My understanding is that tunerPro will allow me to do this. From my reading, it appears that I need an ADX file to tell the software how to interpret the data from ...

I asked a similar question several years ago: http://forum.tunerpro.net/viewtopic.php?t=3221&highlight= Are you trying to modify the tune in the MEFI3 or just wanting to scan the outputs? Most of the MEFI tunes that I am familiar with (the GM RamJet engines) are password protected so that they canno...

Need a lot more information.
Is this on a RamJet 350 engine?

You say it stalls at 1500 RPM. Does it run correctly below 1500? Above 1500?

Did you check the injector pulse with a Noid Light?

Does it idle at all? Can you rev it up to 3000 RPM?

What are the “weird numbersâ€￾? Do you have the correct XDF file loaded in TunerPro?

Normally the BIN file in the ECU is password protected. How were you able to download the BIN file from the MEFI4b ECU? Do you have the MEFI Burn program to download and upload?

boggero wrote: i remove the injector rail and it doesnt shoot gasoline from it

Have you checked the fuel pressure?

boggero wrote:i have the bin files but where do i upload them?

Once you have changed the BIN file you upload it back into the ECU.

I also have the MEFI Burn software suite running on an old Dell laptop running Windows XP. I tried TunerPro RT and had the same problem as you. I could load the old ScannerPro definition file into RT and the gauges would display correctly but it would not communicate with the MEFI controller. I assu...

This may not work with your Audi, but I logged my wide band data by redefining my LM-1's analog output to read from 0 to 5 volts and routed that output to one of the unused input lines (in my case oil pressure) on my MEFI engine controller. Here is a link to how I did it. http://www.carols62.com/ram...

!!!!! Problem Solved !!!!! It turns out that the USB plug has some "issues". Bob at OBD Diagnostics was again very helpful and after all of his remote checks to make sure I installed everything OK, he asked me to squeeze the USB plug where it plugs into my computer... and Ta-Daaa, I was able to rea...

Hi Charles, I found an old XP laptop (Dell Inspiron 8100) and gave it a try... no go... still same SEND COMMAND FAILURE (0x00000006) error notice. I tried 2400, 9600 and 19200 bauds... all on port 4. Thanks again, Bill Well, I have a Dell Inspiron 8000 with XP that I use with the OBD software packa...

There are several wires from the mefi to the DLC. According to the folks at Rinda, the codereader LED is driven directly by the mefi through pin E. The Serial Data Port goes through pin G. You are correct. The GM DTC code reader (and probably also the Rhinda code reader) has 4 pins in the connector...

OOPS... I should have said TP; throttle position sensor instead of TPC. Anyway, all documentation I have points to a mefi4a. My 250 page manual is overwhelming. :shock: The Rinda Tech Codereader works fine. Per a discussion I had with the nice folks at Rinda, the Codereader LED is driven directly b...

JEGS sold me the 12499121 engine back in '08 which has the O2 sensors and TPC. The model number of the MEFI is on its bottom and taking that off is something I wish to avoid. And yes its been sitting around for many years. What is "TPC"? The MEFI3 and MEFI4a controllers look identical, so there is ...

OK I purchased the ScannerPro software and cable from the very nice OBD Diagnostics folks. When I tried to connect, I get SEND COMMAND FAILURE (0x00000006) error. Per OBD tech support, I checked my preferences and port connections using the Hyperterminal on their disk... (very nice to supply that)....

i have an ADX for a MEF3 unit, but I have no idea how similar they are. Hi there, Just stumbled over this site, searching on how to read diagnostics from my MEFI4b ECM. Unfortunately I don't have the protocoll definition for the MEFI4b, so I would like to try the MEFI3 ADX mentioned in this thread....

First of all make a copy of your ADX file in case you mess it up. Open ScannerPro and load your ADX file. Click on Edit Definition, click on the ‘+’ on Dashboards, then click on Main Dashboard. Click on ‘Add Gauge’ and enter the Top, Bottom, Left, and Right location values and the Gauge Type (Analog...

Thanks Charles, I found the parameter list and I'm working through it now. I'm trying to figure out what each parameter means or does. Some are obvious, others I don't understand. on the Scannerpro software that comes with the mefiScan, I can't add items to the dash. When talking to Bob at OBD diag...

To view the codes in ScannerPro select the "Items Lists" tab a the bottom of the screen. The malfunction codes are listed about half way down the listing. Not sure what you mean by "I think that the ScannerPro software that comes with the MEFI scan tool is limited or I cant figure out how to use it ...

Does the engine controller have a GM part number on it, something like 12569494, or 88962717 ?
The part number will probably be on a sticker on the underside of the controller.
Does the connector look like this?

Guys, I am looking to read the engine parameters such as RPM, Coolant, and Fuel flow from my MEFI 3 engine controller, does anyone have the datastream definition files for it? I don't want to modify the cals I just want to look up the data so I can put it on the canbus of my boat. Any help would be...

Can anyone explain how to copy screen shots of tunerpro? The only option that I can make work is export to text. I would like to print some VE tables as they appeared on the screen. Thanks If you are using Windows, when the screen you want is visible, press the PrintSC key. This will copy the curre...

I have the MEFIBurn scan and tune software for my RamJet 350 engine with the MEFI4a controller. I'm not certain but I think the only difference between the 4a and 4b is the CAN bus interface. Unfortunately I do not think there is a specific setting to increase idle for a/c, but you should contact Bo...

Need help coming up with the correct conversion formula for TPS data sent from an Arduino to TunerPro5.

I have an ADX file that works correctly in the old ScannerPro version 5.0574. I would like to be able to use it with TunerPro RT ver.5.0. I downloaded RT, installed it, and loaded the old ScannerPro ADX file. The dash board looks correct, and the Header data looks the same, but I have some questions...

This should get you close
(V-0.5) * 17.5 = PSI

Using the above formula will get the following:
0.5v=0psi
1.2v=12.2psi
1.65v=20.1psi
2.2v=29.7psi
2.75v=39.3psi
3.45v=51.6psi
3.9v=59.5psi
4.6v=71.7psi

Are you trying to add a new gauge or change the item that appears in an existing gauge?

In ScannerPro if you want to change the item that appears in an existing gauge, right click on the gauge and a list of items should appear.

What version of ScannerPro do you have?

Charles

I have never tried TunerProRT, but I just downloaded it and installed it on my desktop computer. Offhand it appears to me that you create gauges pretty much the same as in ScannerPro. I was going to try to see if I could get RT to communicate with my MEFI4a controller, so I installed it on my laptop...

If changing the Mode commands does not work, try this. With the MEFIBurn USB cable unplugged open Windows Device Manager (Under control Panel, System) and click on the “+” next to Ports (COM& LPT). You will probably see a printer and Serial port (depending on your computer’s hardware and perhaps som...

Make sure that you do not have the cable routed near the distributor or any of the spark plug wires. Are you using a true serial cable or the USB cable from MEFIBurn? If you are using the MEFIBurn USB cable, did you install their driver? If you are using a true serial cable does your computer have a...

I have never tried TunerPro V5, but I would assume that it would require that you have the command syntax for the particular ECU in order to communicate with it. As far as I know this information is not available (at least not in the public domain ) for the MEFI ECUs. Also I believe most of the MEFI...

if some other diagnostic tool can do it, tunerpro can as well.... if you know the commands to do so. this is what i thought...anybody know the commands for mefi4.adx to run fuel pump ? From your previous posts I was under the impression that you have only the ScannerPro definitions (ADX file) for y...

To really tune your engine you need the TunerPro definitions and the MEFIBurn program.

Charles

I think the scan tool the manual is referring to is one of the commercial shop tools, not the DTC tool or any of the programs that you have. At least that is how I interpret it in my MEFI4a manual.

Charles

Are you trying to change the item in TunerPro or ScannerPro? ScannerPro only reads and displays data from the MEFI controller. TunerPro works only with the BIN file, it does not communicate directly with the MEFI controller. Changing the item in TunerPro just changes the value in the BIN file, assum...
