I have read brain's right up found here

Engine Management Megasquirt DIYPNP "How-To" - Step-By-Step Instructions - Miata Forumz - Mazda Miata Chat Forums

On page 3 he says how to wire for the gslender mod.

I wanted to verify that I can use the same wiring setup for my 94 as what brain stated.


I understand most of gslenders mod guide but I am confused with his wording regarding wiring.

 

1Q > Input1 IN > Input1 OUT > PE1

PA0 > Relay 1 IN > Relay 1 Out > 1J&4S
or
ALED > 1J&4S
or
WLED > 1J&4S


really depends how it's wired up right now.

 

Right now it is wired 1q>input 1 in>input 1 out> 1J

If I go 1Q to Input 1 IN, The input 1 OUT to PE1.
Then from PAO to 1J.

Problem is PAO is already being used for boost control.

Attached is a picture



sorry for the retarded pic im out in the sticks today on an old *** computer and dial up internet (in laws)

 

That looks like I built it!

move boost to pt7 and do the rest as outlined.


also, you can't go directly from PA0 to 1J, it has to go through the relay circuit first, or through WLED or ALED instead of PA0.


it should end up looking like this:

 

It is one of yours. I am the third owner I believe. I will try it out and come back with results. I finally got my turbo installed this weekend and COPS. So im official.

 

What I have so far. When you say 1j and 4s. I notice there are a lot of them so I just jumped Relay 1 out to 1j where input out was previous wired too. Im not sure if thats correct but heres another picture.

 

looks good, they are probably jumper elsewhere on the board.

 

Worked Perfectly! Thank you very much for all the help and quick responses.

 

I have hit one little speed bump and that is now my ac fan(on the radiator) will not kick on.

 

you need to make sure 1J and 4S are connected together.

1J is the a/c compressor and 4S is the a/c fan. You want to tie them together so that the MS turns on the fan with the compressor.

 

Oh ok. Well it looks like the are connected on other terminals. Before the mod the were both tuning on together.

 

i dunno then. if the compressor is coming on, so should the fan then...

 

Well I guess I could just hard wire it to a switch. Wouldnt that work? I was thinking of hard wiring the fans to switches anyways.

 

NO! why?! no! HISSSSSS booooo

 

My compressor quit kicking on. So I think both of my relays took a crap on me. I took them out and jumped them and sure enough the fan kicked on and so did the compressor. I would normal jump to conclusions and blame it on the ms but I noticed this issue the other day when I was driving the ac fan would turn off and the temp went up and shortly after the compressor would cut off. After a while they would both kick on and go back to normal. his was before I even installed the ms. So long story short I think I just need relays.

 

So the relays were not the problem. So I could just put the wiring back the way it was and just jumper wled to 1j&4s?

 

do you have r14 installed? you need to install a 2.2K resistor in r14, and might as well pop one in the input 2 circuit and run 1V to Input 2 IN, and input 2 OUT to FLEX and use that for launch control.

 

I dont have any resistors at the moment and radioshack is and hour from where im at right now. However after reading gslenders mod guide again comparing it to the pic you posted did you really mean


1Q > Relay IN > Relay OUT > PE1

PA0 > Input 1 IN > Input 1 Out > 1J&4S

 

come on bro, dont **** with me.

 

What are you talking about man? Im serious right now I fried my last ms and im not about to do it again. Please help me out. For real
