spectre ems pro questions.

bbbrad · Post by **bbbrad** » Tue Jun 11, 2013 1:25 pm

I know i should have done my homework, but have just got myself a new spectre ems pro and have a few questions, due to the lack of detailed documentation supplied with it. I can get my head around most features and wiring but am confused as to what the "nos in" and "nos out" wires are for? There is no mention of them anywhere. The launch control... there a wire that is labled "2 step" , I would assume it is for the clutch switch? and it is switched to earth? What is the "option" wire for. Also no mention of it.
I have more questions but this it a good start.
Thanks.
Brad

You may find it difficult to get support for that system here on the MS Extra forum..........

You need to be looking for a forum that supports "spectre ems pro"!

Of course, you might luck out and find someone here that knows what you're talking about.............

Yes support seems thin anywhere! This was my best bet I think. I did read a post while searching that this place would be a help. There was talk of a scott that had alot to do with spectre ems pro. I would love to talk with him, or someone in the know. I need more detailed wiring diagrams that show the whole picture, not just the bare basics of getting the engine running.
Cheers everyone.

Actually it IS supported here and is a licensed Megasquirt variant.

The one I've seen looked to be an MS1 V3 with coil drivers where the injector current sense resistors go.

However, if you bought it new, why not just ask the vendor?

Input is for arming the nitrous system, out is for a relay for a single stage of nitrous.

Yes and yes.

What is the "option" wire for. Also no mention of it.

It is the negative wire for the opto-isolated RPM input. Whether to use it depends on your ignition.

Wow, thanks alot, you guys are the best. I have been in contact with "efi source" who I bought it off and am trying to talk with the tech guy there by email instead of ringing him. As im on the other side of the world. Im getting trough it slowly, i'll keep in touch with you guys. Thanks again.

bbbrad · Post by **bbbrad** » Wed Jun 12, 2013 5:38 pm

Hey Matt, just reading your bit on that "option" wire. If I was running a vr sensor off the crank would this wire be used instead of just a standard earth (for that sensor)?
Thanks again.

You sure its not "optoin" if so thats only used with hall senders. Generally the ms1/extra manual will have feature details that match the EmsPro as thats what It is based on.

Been awhile since I have seen one, they didnt really catch on.

bbbrad · Post by **bbbrad** » Wed Jun 12, 2013 11:47 pm

Hey Paul. Funny thing, just got home from work and had a look. The instalation guide labels the wire as "OPTOIN", but the real loom has the wire labeled as "OPTION". Ha ha. Anyway likely that i wont be using this wire. But I just like to know what everything is for and what it does.
Thankyou all very much for your input. I think I have the wiring pretty much sorted now.

If you can't get the info you need from the supplier, get a refund and buy an MS.

I checked the link I posted and the "link to the manual" has been changed at the other end. I've sent out an email requesting a copy of the PDF manual. When I get that I'll post an updated link to this topic.

PS. Spectre EMSpro IS a Megasquirt.

Thanks for your input jsmcortina. Those 3 manuals are the ones that came with the unit. But they are lacking in alot of areas. But for a progress update, I have been in touch with the vendor and they have helped me a little so far. I am pretty sure I have the wiring 99% sorted. They have also told me that I should use tunerstudio rather than megatune...I cant see much difference between the two myself?
So anyway...I still have the spectre unit in the box still. But was wanting to familliarise myself with the tuning /configuring software. So I have been navigating around tunerstudio and having a play. Obviously I get a error popup to say im not connected etc.
This is where my next problem is...The spectre unit comes with a nice labeled loom. So how do I go about setting the "codebase and output functions" when I dont know what wires go to what parts/pins on the board?
Same goes for alot of the "more settings" outputting options like "fan", "tach", "shiftlight" and "outputs" etc. Some of them like "fan", cant even be enabled to set the temps etc???
Is it a matter of connecting to the spectre and powering it first, before I play on tunerstudio, so that I get an accurate array of the options available to the spectre unit?
I hope that makes sense.

Ok everyone, please bare with me. I have been in contact with a mike from efi source. Good guy. I have sorted quite abit. So this is where im at..
My engine is a 3000cc v6, 24 valve, running a holset turbo. has 6 cop's and 6 port injectors.
-I will be running a 36-1 hall on the crank
-running a simple on off idle valve
-Will be running spark A C B outs, splitting them each into two, to fire the internal moduled cop's, (2 at a time in wasted spark setup).
-i want to also run...thermo fan, tach output, boost control, launch and shift light.
-want to have a play with knock control at a later date.

Sooo, i have set the "Codebase and output funtions" as follows...

fidle ---idle control
d14-----spark a
d15-----spark c
d16-----spark b
multiplex ig----normal
x2(js0)-----fan control
x4(js2)-----boost control
output 3----output 3
pin 10----shiftlight
knock in---knock input

Now there is one area im confused about. The spectre manual says, (one of the few things stated) is that if using a tacho, it must must be set to "x4(js2)". Now how can I set this when its already been used for boost control?? And to add to the confusion I have two nicely labeled wires coming out of the spectre loom, "boost" and "tach out". So how can I have two different outputs coming from the same "x4(js2)" output.

I am a newby to all things ms related. And I am having a hard first time setting one up. I have wired "link" ecus up in the past with no probs and have wired a few race cars. I am abit down at the moment trying to work all this out. I would be most greatfull for any help on these matters.
Thankyou
Brad

Anyone out there help???
Can I not run tach out and boost control at the same time? Because the "codebase and output funtions" can be only set for one or the other, not both!!! Am i missing something?

Post by **jsmcortina** » Sun Jul 07, 2013 7:08 am

Looks like there might be an error in the Spectre docs for Tach.

Checking the EMSpro schem and cross referencing the Megasquirt V2.2 and
V3.0 mainboard annotated schems in the MSEXTRA manual I believe:

Tach = PTA2 = X5(JS3)
Boost = PTA3 = X4(JS2)

Hi jmscortina, I have been going over everything and was wondering about the x5/js3. There was no mention of it at all. What your saying would make everything fall into place nicely. I hope your right, make sense to me. I havent even unpacked the ems unit fully yet because I like to get my head around a product fully before i dive into it. Im pretty sure I have enough info to crack into it now. Wish me luck.
Thankyou all very much. I'll buy you all a beer.
Cheers
