why the hell have I written all my mails in English, Matt! Nice German, well, sort of...

 

*LOL* Matt.. you are right, better in english

Yes i understand that all, the current status of the diypnp is fresh, but you know...

Maybe have you a PDF of the current Manual anywhere?

 

There are some things i dont understand...

Where is the O2 Sensor Jumper? Is this the O2 Sensor Contact? *Kopf rauch*
If i use a Various TPS on a 1.6 91er Miata (like from Automatic Miata), what have i to do?
What if i dont have a MAF ?

Yes i read a bit in the Manual, but i dont understand that what that means at most.. and no online translator can help me there *lol*

It is for a Mazda Miata MK1, 1.6, Year 1991

 

It was originally written on the website, so there isn't a PDF at the moment. I will see what I can do.

This connects to the MicroSquirt's O2 sensor input, so it either connects to the O2 sensor signal wire in the harness or the LC-1's analog output.

Splice it into the wiring and wire the TPS signal, VREF, and SG pins to the three wires you're using for the TPS.

Wire an IAT sensor to the temperature terminal on the MAF connector, just like with the MSPNP.

 

Because your English is a lot better than my German.

 

So if I'm installing this in a NA6 with the standard wasted spark do I install all four Ignition drivers or just A and B? I presume I'm not jumpering the high current jumpers?

Is there anything I should be doing different from the standard instructions to suit a NA6 with standard ignition and injectors?

Edit: So do I install all 4 drivers but jumper A and B?

 

How many stock manual trans TPS wires come in on the stock harness???? If it is less than the three needed for the VTPS we should use the DB15 and then jumper to VREF and SG. I'm sure at least the TPS signal wire comes in through the stock harness.

The pinout has both SG points used, so what do we do about that?

AC circuit question. Pinout lists and input and ouput on adapter board. Are these two supposed to be jumpered together, or do they go somewhere on the main board ? relay?

 

The stock manual 1.6 TPS has 3 wires to the ecu.
Red VREF is at pos 1N
Black/Light Green is Signal GND on 2C
Light Green/White is SG on 2L

You should not need the DB15

 

Are the positions you list for the diypnp jumper harness, or the stock harness? I don't want to solder to the wrong jumper.

Do the diypnp pin identifier (i.e. 4p) correspond to the stock harness (4p) positions etc.

Here are a couple of camera phone pictures. When I'm done I'll upload the pics I have taken with my good camera.





Thanks

 

Install and jumper A & B. You don't have to install C & D if you don't want to, though I'd just go ahead and do it. Don't jumper them though. You can use them as GPO if you need them.

 

You're makign this too complicated. Just bring the TPS signal on the TPS wire. Everything else is handled, assuming you make the VREF and SG connections as indicated. Pull out your car's wiring diagram if you need to further clarify.

 

You need more cooling paste

 

I didn't notice.

Dude you use the teeniest bit of that stuff, like the size of a small grain of rice. It will spread out when the transistor gets hot. It just fills in the gaps between the surfaces of the transistor and heat sink, you don't want to actually have a coating of it. Maybe you can remove the setscrews, pull the transistors out, and clean it up some?

I'd probably try the 5V power supply first. It's probably the least important transistor.

 

Hi Ben,

some more questions about the sequential stuff.

What is to change in the MSQ? Alpha Firmware of course. Else?

How do you wire(jumper) the injectors? In the order of the cylinder numbers?

As I am running out of outputs, when I wire sequential injection AND sequential ignition - I have to choose. And I would choose to do the injection and leave it wasted spark. Dumb? Any other options? I need at least the fan output and the boost output, PWM idle valve.

Thanks for your help.

 

I haven't read up on or completed it yet. I need to make it over to DIY to pick up my sequential card. Because sequenital injection is accomplished with an add on card, I'm not sure if there will actually be any changes to the .msq. I'm thinking there won't be.

I'd assume you'd connect them in firing order.

There is no relation between running sequential fuel and individual spark. You already have enough outputs on board for individual spark, idle control, fan control, and boost control. Sequential fueling will require the add on card.

 

You have? (enough i/o)

 

VAR TPS

I build this in the past for the MSPNP, so the harness should be correct, right?

 

You use the add-on card for seq injection, so yes there's enough I/O.

Assuming you wired it up like stock, yes.

 

Here a shot of "my" DIYPNP fitting for Miata 1.6 MK1, 90-93

Stock Ignition, No MAF, VarTPS (Stock wiring), KnockSensor, LC-1, Boost-Controller

 

Ah, cool then...

@Werner - looking nice. Already wired for sequential ignition?! Why did you wire all 4 ignition outputd as well as the ign1 and ign2?
