sweet i thought about doing this myself i wanted to build a stroker and thought about putting a twin screw on top of it.
would be great because you could go to the junkyard and grab the coil on plug setup off a 00/01 cherokee 4.0

got it figured out... turns out i had a strand of wire touching inside the db37 connector i soldered it back in place on the pin slipped tape in between the pins so no more problems and its working again..

it was hard to see the strand as it was touching behind the pin..

everything working good ...

umm ok .. yeah it uses the ford ones sold on the DIY website i cant recall the exact value of them off hand but yeah its the right ones plus is a single one no switching.

like i said it worked fine before fan functioned and it read the right temp

but how about the TPS?
when i checked battery ...

i got everything connected in the factory computer, i got the wiring for MS either touching the pins that come into the factory computer or i have the pins in the factory computer completely remove from the factory computer and only touching the MS wiring.

if you know what a ford computer looks ...

i can understand i guess the sharing of sensors you guys keep mentioning but the thing is it never had a issue before and if its being a issue why isnt it messing with the IAT and why do i lose TPS when the engine starts? but not before with just key on.

i guess ill get my hands on another spare ...

everything is shared with both ECUs only difference is MS has control over injectors and spark

i had to in order to keep the fan control setting and cruise control i needed to keep the use of sensors to the factory computer

the factory fan control is used by speed sensor and temp sensor it kicks ...

anyone?

ok i just reflashed then i imported the saved msq i had saved of it before the flash and also checked all the wires... nothing it touching anywhere that is remotely related and i even double checked the resistors i have installed on the MS mother board both are reading perfectly to each other yet ...

they both just read the same voltage. i didnt add tps to one and then the other they both read from the same source

all threw the factory grounds. see the factory had the grounds all on the same wire which all fed right back to the factory computer, it works a lot like the MS does but i did add another sensor ground since i have a LC-1 wideband i wanted a good reading there also and so i wired in another ground ...

i got a MS2 version 3 and ive been having weird issues where tomorrow im gonna reflash the MS completely because i made the mistake of calb the thermo sensors while running and i think it is causing the issues anyways the issue im having is this.

the tps signal when watching the datalogs and all is ...

nevermind after about 45 mins of looking i finally found it... thanks any who

been a little since i messed with MS2 i have and i was gonna play with it tonight but i cannot find the wiring diagrams for my ms2 v3.0 everything has changed there used to be a diagram that shown the connector and what pins went to what... if someone could help would be great

never mind this can be ignored i noticed on the DIYAutoTune page it has the resistors to buy for the ford clt and iac

i figure somebody might know what resistor i should use in my MS for on a ford taurus SHO im running in parallel with stock ECU im using the stock computer to control my cruise control, digital climate control and most importantly my fan since the stock computer uses the VSS and coolant sensor which ...

works like a charm i am able to control the butterfly circuit without a relay or transistor

got it figured out now thanks as always matt..

one thing i found out was the ports are reversed when i pick IAC1 it controls IAC2 and vice versa

im using the IAC to directly drive a device.

im gonna check about what i got jumpered but since i dont have a stepper IAC i didnt do anything to set up a stepper IAC probley there in lies the problem.

weird thing is the IAC2 outputs had battery voltage

im trying to setup controls for the butterflies on a taurus SHO intake but i dont know if its im tired or what but im not understanding how i set it up in spare port settings..

could someone just type it out for me so i know what to set..

im using IAC1 port since it can handle .5 amps which the ...

nevermind i found the awnser to my question...

i dont know if its just me or what but im having a heck of a time figuring out the guide on how to set up the spare ports...
