I understand the fuel pump solution. That's easy enough.

Not following on your PA0 usage. It looks like to me PA0 istied directly to something at the adapterboard, and you have your boost control input going to the CANBUS pin. Maybe it's just an illusion on the picture? But you shouldn't have a processor in or out tied directly to the adapterboard. And the CANBUS is for MS to MS communication. Am I wrong here?

PAO is definitely not going to the boost control. It looks like the pin directly across from PA0 is hooked up to the boost control. Out is going to a DB port which is correct.

HI,

I tried to set up my MSQ for the DIYPNP and noticed, that I am not able to assign any other output then "FIDLE" to the boost control. WTF?

I thought PA0,PT6 and PT7 should be able to control boost...

I haven't tried anything in tuner studio yet.

Here is a link for the I/O extender board. Looks like they are also making a a GPS logging system with 3 axis accelerometer.

I have the answer. I had to deactivate Microsquirt full inside the Project Properties in TS and leave only Microsquirt Module activated.

Thanks to Matt!

After some searching and thinking about what Matt said; the above comment made more sense. I didn't realize the 90-93 cars didn't have their fan controlled by the ecu. I can just leave my fan controlled by the thermosensor and life will be good.

Just for clarification. 90-93 miatas do not need the ecu to control the fan. It does not need to be wired into the diypnp.

Yup, there's only one wire coming out of it. It goes to ground at 97°C. Install in your 1.8 and you save a spare output.
I'm going to use one in my next build and use the spare output as a shift light.

WestfieldMX5

It only comes on when temp is >97°C, so I don't see why you'd need a switch at startup. Unless it's a hot start? You could put your clutch switch in series, but than it would cut the fan each time you shift .

Ben,

Would you post your msq. I am trying to learn TunerStudio and MS for that matter. Since you are using the same ECU it might be nice to look at your settings. It may make things a little more clear as to what's going on.

Basically I want to understand the ignition, fuel, accel enrich, and output settings and why they are what they are. I don't want to just plug in numbers and be happy that it works. I want to know why I'm changing these values.

I don't want your time or ignition map so feel free to change them before you post if you are sensitive about others having your tune.

Thanks

Ben

I'm not unwilling to share my .msq, but I don't think it will help you as much as you think. Our cars and are builds are different, at least half the settings will be very wrong.

It might help me with the ouput settings.

I'm looking in tuner studio right now. Under output port I have selected PA0. This will be my boost control. I don't understand what I should select for the conditions. I don't know what all the ouput channels area. What is the threshold, < > = ????? It is this are that I will need to setup for my sequential ignition and fuel, boost control, etc and I have no clue as to what I'm doing.

Press F1 for help on most any screen.

If don't know what < and > mean, then there's not much I can do for you!

I don't have MS stuff on this computer, but you set up the condition you want the output to switch states, if you want it to switch states if the condition is true or false, and if you want the output to go high (+V) or go low (ground).

You can also set up a second condition with basic logic.

For instance, these are my cooling fan conditions:
CLT> 190°
AND
RPM >500
True
Ground

What's your email address? I realized I have a .msq in my hotmail.
<edit> n/m I had your address, I forwarded a file

F1 fantastic this will be of significant help.

< > **** man, I am a physicist, at least pretend I can grasp a few concepts.

I am now getting a better understanding of what MS needs as inputs. The LINK was very straightforward in comparison. If I wanted 12 psi max boost, I just put the corresponding kpa in the rpm range.

I'll see what I can do with this new info

Zaphod

You don't need the boost output at the output ports menu. You set this at the Boost control settings menu.

xitsam

You are all right..

I use PA7 for Boost-Control and PA0 for FAN (FAN agreening with Manual NA 90-93 from Matt)

EDIT: I just read, i dont need the Fan Wire? Ok, the i will unsolder them.
Thanks all.

xitsam

Ok, i have now unsoldert the PA0 to 1R.

But i will still use the PA0 for an Extra FAN, so i soldert the PA0 directly to the DB15, so i can program the PA0 for switching the secod fan with MS2.

Does it work this simply ?

miatauser884

iTrader: (11)

That will be easier. It seems like setting up tunerstudio is becoming a little easier. I thought I was going to have to set all of these variables for the outputs, but it appears that isn't the case. Thanks for the heads up.

Anyone know what wire the tach comes into the factory harness on the 90-93. I looked at brain's diagram put didn't see a pin for it.

VTPS jumpers needed: SG goes to 4C and 4D, tps signal to 4K, and VRef goes to 1M

Ben

iTrader: (33)

No, you have to run it through one of the on board relays.

Tach signal to dash is generated by the ignitor.
If you're going to go with different ignition (like LS2 coils like me), then you'll need to worry about the tach out. If you're using ignition with on board tach drivers (stock or toyo coils), you don't have to do anything.

Zaphod

Hi Werner,

I am going to explain at the Turboforum in German.

xitsam

Thank you, i thought that, that ist´nt that easy

Edit:
Now i changed my wiring to PA0 to Relais#1 IN and Relais#1 OUT t DB15.

By the way..
Please make at the next Version of the DIYPNP the DP15 HOLES BIGGER
