Hey all,
I have a 86 toyota 22ret with ms2v3 2.905 code. It will start run for aprox. 2 min or so then it starts to miss and eventually dies. mega tune tach goes to 0 then will run for a few secconds or minutes then the tach will bounce to zero again. its like someone turned the key off. i switched ...

I have a toyota 22ret i put a megasquirt 2 v3 on. The stock harness has resistors between the battery and the injectors. My question is would the resistors cause a problem when tuning the INJECTOR OPEN TIME and PWM TIME THRESHOLD it only will idle when those numbers are above 1.5 - 1.7. I really ...

yes i am getting a rpm reading on the hall circuit now.

i need to use the vr circuit for its what the toyota uses. i read in the forums to change it to a hall or opitcal to see if your o2 works. down the road i might switch it to a hall sensor so it needs to work also. but for now i need the vr circuit to work.

i didtn have anything in d1 d2 was jumpered. i looked a the instructions again and found a missing jumper in d1. would the missing jumper in d1 cause the vr circuit to not work? If it wouldnt matter if it was there or not how would i start to trouble shoot the vr circuit?

i have nothing on either side of r39

I dont have a megnifiing glass handy ill have to go to town to get one in the next day or so then inspect the solders. i started out using too large of solder and too large of a bit then i bought the right tools to do the job. those were the first ones that i tried to solder.

with the mega squirt powered up i have 5 volts at TSEL. when i add 12 volts to TACHSELECT nothing changes. When I ground it I still have 5 volts.

any ideas or suggestions on how to trouble shoot my rpm issue? is there any way to check the q22 and q23 transistors? i had a hard time soldering them in the first time

i have the mega stim v2.21 i have tried the switch either way in the pnp and the npn positions and it doesnt make a difference.

MS II V3 2.89 code

i assembled my kit all the way to the rpm section. i i selected the vr circuit originlly but had no success in getting the pots tuned for a rpm. so i read in the forum to change it over to the hall circuit so did that and no success again. as of this moment i have xg2-xg1, TSEL ...
