MegaSquirt II Successfully Running on 7M-GTE!!! (Lots of pics and walkthrough)

[87_7MGTE]

1. so for ac, what exactly do i need to do, im still not understanding fully. do i need anything from the stock ecu or stock harness?

2. as of now, yes, MSII can only monitor knock, but in the next release, it will be able to control timing:

(i kept the images big so you could see the settings)

and here are the wheel decoder settings:

I don't know were the switch power comes from on a MKIII but on mine I ran power to the a/c on switch then through my hi/lo pressure switches and then to the a/c clutch. The a/c compressor power isn't on the engine harness so you don't need anything from that. The only thing that was on there is the plug that send the signal (+) to the ecu to idle up. The expansion valve controls the refrigerant flow. The switches are there just in case there is a problem with either no pressure and to save the compressor or too high of pressure, maybe a fan stops working.

do you guys know what values to fill in for the trigger wheel settings, and how to wire it? (pic above)

 

[Clifton]

This is on MS. I don't really know the difference yet. One guy has done a few 7M's

for the guys lookin to go megasquirt with the edis ignition, you may want to check out that group buy. its for a bolt on crank trigger for use withthe edis setup.

also, i looked at the pics again and didnt see pics of the bracket you made to mount the sensor. did you ever get a chance to get pics of that?

 

[87_7MGTE]

yep, just forgot to put them on my website

before i painted it:

Ummm good idea on the Braket BUT you MUST use thicker material!!

That one WILL vibrate and you will get inconsitant readings! Trust me on this one!.

I took the easy way out and used the Flywheel as a crank trigger and the plate between the trans and block to mount the Sensor .

ooohhhhh, I like that idea. Cleans the install up a bit, any pictures?

car runs awesome with that bracket. its been modified a little since that pic, and im going to make a new bracket soon so i can use the stock fan.

IJ: thats awesome! if my motor was out i would totally do that.

I know this is an old thread but I need some info:
1.Is your car overheating with 2 x Permacool 12"s

2. can a 36-1 wheel fit on the back of the pulley instead, which would allow you to retain stock fan

1. car overheated in the beginning because of cooling system problems, now it is fine. i have stock radiator.

2. no idea about that. didnt seem possible because it seems like the pully wouldnt sit all the way on the crank/key. you can make a different style sensor mount and keep the stock fan, which i am planning on doing shortly.

Easier to do what Duane does and that is do the 60-2 or 36-1 cut outs right on the pulley itself.

i wanted to do this, but i didnt know how much it would cost, and i dont know a shop around me that would do that. i love how duane did that though.

nice but i don't have the time for mm2 and to learn how it works

as in tuning

i just going to weight it out to if any mroe new stuff comes out mabye maft pro that can chnage timing

Only have to pull the Trans and Flywheel to do it no need to pull the motor out!

Could you take a close up pic of what the VR sensor looks like?

I just helped a buddy mount an Electromotive 60-2 wheel and magnetic sensor on a mazda block and was curious how similar the sensors are to see if I can use a similar bracket.

Havent had a chance to get to a junkyard to get the 36-1 wheel and sensor yet.

Also for the electromotive sensor, the bracket has to be made from a non-ferrous metal, is that true for the VR sensor too?

:naughty: Bump

 

[87_7MGTE]

ill take a picture of the sensor tonight when i get home.
