What are you doing with the fuel pump and PA0?

 

I'm wondering why you wired S1 -S4 as well. I don't believe that you need those wired in. Even if you are going to run COPs I think you wire ign1, ign2, Aled, and wled.

 

Alright, I'm back for some help. I appear to be out of i/o circuits that I need for the fan relay.

PT6, PT7 sequential injection
PA0 boost control
wled, aled used for ignition

How should I wire my fan now that I'm out of on/off controls?

 

Doesn't matter. Directly out from the drivers is more convenient to the DB15.

S1=IGN1
....
S4=WLED

To risk sounding like a broken record, you get the sequential card for injection. That frees up both those outputs.

 

The sequential card still uses PT6 and PT7 it's connected to them through the sequential plug in. I emailed Matt about this.

"PT6 and PT7 are connected to the sequential board through the 10 pin

wheellll then, that's a problem. I have PT6 to cooling fan and PT7 to VICS

 

In case this helps anyone, or anyone can help me.

 

I may have to get rid sequential spark. It seems this would be a better option than removing sequential injection.

There is one more output that is yet to be determined with new firmware. Maybe we should request that this be another on/off output. Looks like we need another module that will supply more outputs

 

I personally would rather have individual spark than fuel.

There is a I/O board coming out soon. That would give the ability to get crazy with stuff like dual stage cooling fans n junk.

 

Well motherf*****. When's the new board supposed to come out? I just spent $38 bucks for sequential injection not realizing it was going to screw up my setup.

If I had known this, I would have waited to buy the sequentail chip until the next i/o plugin came out.

I'm aggravated, I'm going to get a beverage.

 

You could give up the fan output and use a 1.6 thermosensor to activate the fan. Alternatively you could modify a Velleman mk138 to the desired temp range. Here's the schematic.

 

I wonder if I could use the thermosensor with the clutch switch so that the fan would only come on when the clutch was pressed. Maybe a main switch that I could turn on and off so that it wouldn't come on when the car was being started. Of course I plan on bypassing the clutch switch on startup anyway.

I really just need a temporary solution until the i/o add on comes out.

 

I just wired them because, we will make that easy to use in the future, just setting the next 2 jumpers 3 and 4.

 

But I think you don't have to jumper S1-S4 AND IGN1&IGN2 S1/S2 should be the same as IGN1/IGN2.

And Ben is right, why did you wire the fuelpump to PA0? Fuelpump goes to wherever the fuelpump is on your model at the adapter board.

@all:
How do you wire IGN1/IGN2 for wasted spark with this tiny holes in the main board. Jumper at the adapter board?

Nothing, it just crossing over together

PA0 goes to 1R

and

Fuel Pump to DP15 Pin 15

 

Maybe it is the same, but for a Plug&Play solution it is easyer to use the DP15 pins, simply wire them up to the Coils, otherwise you have to lead of the correct wires from the stock wires.

And i think, if Jonny goes coil, he also make sequential inj as well, so the wiring gose at once.

I just think what is the cleanest solution, not the easyest.

 

Hm? Stock?

 

More specifically, what are you doing with them? Why does FP goto the DB15? Why do you have a processor output connected directly to something?

 

I just follow the hints you wrote here..

Fuelpump is switching the ground, because the 90-93 dosent switch with the ECU (using MASS AIR FLOW).
Corrected in the new manual from Matt posted here in the forum.

And the PA0 i asked:

If I remember correctly I jumped PA0 to the IN and the Out I jumped to pin 15 on the DB15. I believe the IN will become more apparent with use of the tunerstudio software. I assume that PA0 will be the value you change to define the max psi/kpa that you want to run.

And this is, what i am doing with it.
If i am wrong, please correct me, i dont know what is realy right, spezialy for the boost-controler thing.

 

I think I know the answer for the fuelpump - as the 09-93 Miata doesn't seem to have a fuel-pump wire to the ECU so you have to wire it separately via the MAF connector.

About PA0:

You have to wire from PA0 to BOOST (at the main board) IN and from BOOST OUT to the DB15.
