seattlejester Posted March 9, 2014 Share Posted March 9, 2014 (edited) First off, I would like to apologize for the short info, I will add to it once I get some food in my system. Setup MS 2 pcb 3.57 3 spark output drivers Toyota CPS (24 tooth missing two teeth, 22 remaining teeth) GM Coolant temp sensor GM Intake air sensor 7mgte, coil on plugs Connected to tuner studio and it is reading an rpm signal of 65000 or so RPM. I tried changing a few settings, even unplugged the cam position sensor and I could not get the 65000 rpm signal to drop. Power cycled, but TS keeps displaying the setting configuration error. Following instructions the mini terminal is blank and does not load any error even when power cycling. When I was testing last week, the ecu would read the signal fine when I rotated the CPS by hand. All the other sensors work (AFR, CTS, ATS, MAP), although the TPS didn't seem to want to be reading anything as well. Any thoughts? I will attach my msq momentarily CPS setting is 24-2 cam speed, starting 3 teeth ahead for 90* btdc for tooth number 1 angle.

winstonusmc Posted March 9, 2014 Share Posted March 9, 2014 What are you using, the diy wheel? I use that and have it set at 12-1 crank speed. Quote Link to comment Share on other sites More sharing options...
seattlejester Posted March 9, 2014 Author Share Posted March 9, 2014 (edited) I'm using the stock toyota wheel which was a 24 tooth wheel with a separate wheel 1 tooth wheel. I removed the 1 tooth wheel and ground off 2 opposing teeth on the 24 tooth wheel turning it into a 22 tooth 24-2 wheel. Hmm hbz isn't letting me upload the msq. msq here And mind you, the computer is reading 65000 rpm on startup with just ignition on. Megasquirt asks that I turn off the engine before even entering test mode. The engine is not running during this whole process. I mean if I look at it logically, the ecu is receiving a signal says that is reading a pulse every ~1/1000 of a second. The ecu is DC powered so I can't fathom how it can read a signal of that nature. Edited March 9, 2014 by seattlejester Quote Link to comment Share on other sites More sharing options...
Metro Posted March 9, 2014 Share Posted March 9, 2014 65k+ rpm is a software configuration error. Specifically, error #27 I think. A forum post about the error messages says this: "If you are seeing 65,000 rpm, but no message, go to Communications and Mini Terminal. Then turn your Megasquirt off then back on again. You will see a message displayed telling you why the code found a problem with your settings." It's late, but I don't see anything obvious that's wrong in your MSQ. Double check all the settings you've changed and maybe start a new tune from default and try again. Quote Link to comment Share on other sites More sharing options...
seattlejester Posted March 9, 2014 Author Share Posted March 9, 2014 Thanks for taking the time to respond. I did find this. Which also says it is some type of configuration error. That megasquirt actually isn't reading a signal that it is an error output. When I open mini terminal and power cycle no message shows up and it won't connect until mini terminal is turned off. I did open a new project and loaded the msq to find the same thing happen. I may have to just open a new project from scratch and see if that results in the same problems.

Matt Cramer Posted March 10, 2014 Share Posted March 10, 2014 Those wheel decoder settings would be right for two consecutive teeth ground off; if it's two opposite teeth, set it for a 12-1 crank wheel. Setting the spark to "wasted-COP" will use all three LEDs, JS11, JS4, and JS5 as spark outputs. If using three spark outputs - even if wired to COP coils - this should be wasted spark. You've also set JS11 as a boost control output and as a programmable on/off output triggered by coolant temperature. So you have set JS11 for three separate functions. This needs to be fixed.

seattlejester Posted March 10, 2014 Author Share Posted March 10, 2014 So steps to be taken... It is two opposing teeth that were removed, so I will reconfigure for 12-1 crank trigger. Change settings from wasted-cop to wasted spark. Change JS11 so it only is used for one output. I actually ordered a custom board from your website. On my order sheet it says... I have PAD1 spark A outputs DB37, PAD3 Spark B outputs DB15 pin 10, and PAD2 Spark C outputs DB15 pin 11. Boost control is output on DB15 pin 5. To get the actual pin designations, I would have to open up the ECU to take a look inside? Thanks for taking a gander! I thought maybe the update or the fact that my laptop is a mac was playing haywire. Glad to see it's just some type of user error. Quote Link to comment Share on other sites More sharing options...
seattlejester Posted March 11, 2014 Author Share Posted March 11, 2014 Changed wasted spark output, tooth wheel settings, and the boost control and error went away. Thanks guys! Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted March 11, 2014 Share Posted March 11, 2014 Boost control would be set up as JS11 normally, so you'd turn off the other uses (coolant based on/off and ignition). Quote Link to comment Share on other sites More sharing options...
seattlejester Posted March 11, 2014 Author Share Posted March 11, 2014 I believe I am using D14 as the ignition, I will have to check on the coolant based on/off. Thanks for the help! Just had trouble starting last night from the lack of voltage from the RPM signal. Will be adjusting the pots for the VR and hopefully will have good news later tonight.

sabaozinhox Posted January 28, 2016 Share Posted January 28, 2016 good morning friends, I am Brazilian! I am facing the same problem I have a ms1 v2.2 , my reading 52000 rpm is what can this be , I have a tone wheel 60-2 GM omega 2.0 someone could help me ? sorry the English by the translator is , I do not speak much English. grateful friends , have a good afternoon!

seattlejester Posted January 28, 2016 Author Share Posted January 28, 2016 Msq available? Or even screen shot of the settings? If you make a new post with all your settings and the msq or screen shots it may be helpful to others who can chime in. If it is similar to my problem then it is a configuration error with too many shared inputs. A quick look at the settings to make sure there is no overlap may help.

sabaozinhox Posted January 28, 2016 Share Posted January 28, 2016 beauty, I will put my msq and I will give more information , sensors are all ok , in ms2 he was reading the normal signal 230rpm , now in ms1 it does not read right, I do not know if it's because of the tone wheel , 60-2 GM Msq available?
