Well if you are talking about the VREF for the TPS and things like that i havnt measure the voltage coming from that wire yet but i know when i was assymbling the megasquirt in the first couple of steps, after installing the 40 pin connector it says to check the voltage at pins 19 and 20 for 5 volts ...

Well you see there is another issue i am having. i will be sure to test those tonight and see how things turn out but my map reading is pinned all the way to about 290 or so and my battery is pinned also and reads like 29 volts when im only using 12 volts on the stim itself.

Thanks for the input matt. now are you talking about removing the daughtercard and testing the pins on the daughtercard or removing the daughtercard and testing on the 40 pin connector on the pcb board itself. or just leaving the daughtercard plugged in and testing it right from the top of the pins ...

I dont know where exacty to check the adc inputs. i checked at the DB37 connector to see if my stim was working and when i turn the pots the voltage did change no probem but obviousy thats on the end of the stim lol. where can u test the adc inputs coser to the ms2 daughtercard or on it so i can see ...

Hello any help in this field would be greatly appreciated. I built my MS-2 v3.0 board and i am currently in the process of testing things and figuring out right settings for my car but ive hit a dead spot. I have the stim plugged in. MS-2 has power and everything but I have no control over TPS, IAT ...

Thank you for the response. When i have the megastim hooked up and i give it an rpm signal by turning the pot the fuel pump light shuts off and the IG light comes on and I1 and I2 alternate turning on. The IG, I1, and I2 being on when i give the comp an rpm signal i would think is normal. but the ...

When i plug in the megastim v2.21 into my megasquirt2 v3.0 the fuel pump light is the only light on. Ive been told this is normal. after loading the firmware it flashes i have been told this is norml. Now i have no control over the coolant temp, intake temp, or throttle position, and i can only turn ...

Also if i move the O2 knob just a hair it works but turned anymore it stops working. Also when i jumper those and the switch on the rpm knob is on pnp the pump light goes out and the IDL light stays off the entire time. but if i switch the rpm knob to npn the pump light goes on and nothing works at ...

I have also just found out something. I did not install D1 or D2. Instead i ran jumpers bc it was what was recommended. I found out that if i run a jumper wire between both the D1 jumper to the D2 jumper i can control my RPM's on the stim and to the computer. The IG light lights up and the I1 lights ...

I ordered the MSII V3.0. in step #38 it says to install Y1 on the pcb board itself not the daughtercard. Should i remove it then? I was able to install the software but i am having communiction issues aparently. Im talking about the Y1 that goes on the little silver rectngle on the PCB board itself ...

I am having the same exact issues. LED D14 is constantly on and when i first load the firmware my fp light is blinking but when i go and same the msII settings under megatune the fp light doesnt blink anymore it just stays on. No knobs are working at all and both temp gauges pinned at 170 and my tps ...
