I have been looking at the wiring for the megasquirt 1 V3.0 main board and there is no place for the MAP sensor. Does this board not use a MAP sensor?

Hello,

I am trying to create a VE table to tune a CNG engine using throttle body injection. When I try to generate a VE table it asks for the MAP at idle and peak vales. I am not sure of the MAP that are predicted for my specific engine running natural gas. Does anyone have an idea of which MAP I ...

I have a megasquirt I with a V3.0 main board. I am trying the tune a CNG engine and have been looking for a base 12×12 volumetric efficiency (VE) table, the 12×12 air/fuel ratio (AFR) table, and the 12×12 spark advance table. Does anyone know where I could find such tables as a base reference for ...

Hello,

I changes the fueling algorithm to speed density fueling algorithm and the EGO O2 sensor to Narrowband in a new project and now the system is working. I have asked this in another section of this forum but I will ask here also. I want to run an injector with a 8.7-9.1 ohms coil resistance ...

I am trying to choose injectors that I can use with a megasquirt system. Which level of resistance (ohms) injectors can I use standard for a megasquirt ECU?

Thanks,

I got a large error message today which caused my tunerstudio project not to run. It reads:

A problem was encountered loading this project.
Reported Error:
A critical Error was encountered in this projects ini file.
The following message was provided:
"MSnS does not support MAF"

Any ideas on how ...

I worked on this all of yesterday and found that I had not set up the project correctly. Now TunerstudioMS is working great. Hopefully I don't run into any more major problems. Thanks for all the help

Wow, I feel really dumb right now. That was it and now it works. Thanks so much.

I cannot select anything under the communications tab other than miniterminal. Everything else is light gray and cannot be selected. I am guessing I should be able to get to the settings tab to open a connection but I cannot.

Where is the detect button in tunerstudio MS?

There is no longer an error message with Megatune but I would like to used tunerstudio MS which I have already bought. How do I get tunerstudio to communicate? When I open tunerstudio with the megasquirt 1 connected I cannt open the settings under communications.

I just wanted to add that the MegaSquirt I just successfully connected to my computer using MegaTune but I am still receiving the error message right when I open MegaTune:

Controller code version does not match signature in MegaSquirt-I.ini

Expected "0x14" (found in ini file)
Received "0x51" (from ...

I downloaded Megatune and tried to open megatune but got the error message:

Controller code version does not match signature in MegaSquirt-I.ini

Expected "0x14" (found in ini file)
Received "0x51" (from controller)

Table corruption may occur, this is usually a very serious problem.

When I open the COM check program I get the message "Bowling and Grippo v. 2.xxx or 3.000" for COM 1 at 9600 baud.

I tried checking the circuit board by jumping pin 12 to pin 13 on the 40-pin processor socket [near R44], using a snipped-off component lead and checking for a loop back with ...

Hello,

This app is great but I not specifically tailored to natural gas so I can get an injector size but not for natural gas. Thanks for the thought though I will try to compare this apps calculations to mine so far

Hello,

I am trying to use my megasquirt MS-1 V3 system to convert my car engine to run on CNG. I have been looking for options of different CNG injectors I could use but have run into some barriers. First, what would be the best way to calculate the fuel flow rate I would need for my engine? Then ...

Hello,

I was given a three year old assembled V3 main board which was working correctly three years ago. I connected the board to my computer via a DB9 cable but TunerStudio will no recognize it at all. Are there specific tests I can run to make sure my V3 main board and stimulator are still ...

Hello,

I am new to megasquirt and was given a preassembled ECU V3 main board (which is 3 years old). It was working perfectly three years ago. I have TunerStudioMS loaded on my computer. From the assembly directions online it sounds as if when you connect your computer to the ECU which is being ...
