its not supposed to be going to ground its supposed to go to one end of a 100ohm resistor for my ebc. not at home to verify but im pretty sure i diddnt make a mistake there...even though the pic looks like it goes straight into ground. ill check my wiring there too.

i diddnt know what to do i panicked...i figured since they were both for a similar motor and they both were for tunerstudio i diddnt think it mattered i just started looking for random maps to get the car started :(

how far off track am i????

you're missing the Green line above the blue which is the cam. blue is crank, and red is the error. where the spikes are where it's not seeing something it expects.

use the DIYPNP basemap. that could be an issue trying to load a msI map. http://www.diyautotune.com/diypnp/ap...93-16b6-mt.zip

you leave it as it. all you need to do is change the wide or narrow band.

ive established that im getting continuity between the coil trigger wires and ckp and cmp wires all the way back at the pcb.

idk what the problem is could be a bad cas but i actually bought a new BWD brand cas for a 97 miata with a brand spankin new pigtail from a alternator that just happen to plug right in.

ben from diyautotune says it wont start unless it gets a cam signal as well. how would i go about testing the cas does it directly output a fluctuating signal that i can connect to a cheap Chinese multimeter and confirm that it is functioning?

ok so i went ahead and probed the ckp and cas pins on the sensor while spinning it with my finger the results are that the ckp sensor goes from 0-5 volts but the cam angle sensor pin only fluctuates by .15ish volts.... it goes from 10.9v to 11.05. :( think its a defect??

Check for a short between JS10 and 12V.

If he's loading the DIYPNP base map isn't that going to set up for a microsquirt module instead of a full MS2? I don't know how big of a difference that makes, but I would think some of the pin assignments might be off.

itll convert over. but yes you're right some pins might be off, it's just a better start than going with a MSI map.

not really sure how to hunt a short circuit down... i mean js10 is a hole. i have 2 wires going to it...neither of which are 12v. one goes to 5v trough a resistor and the other is just connected to the cas
