I'm using the Spectre eMS-Pro (HELP!!!) - SRT Forums

DarkDangler · 06-05-2007, 02:39 PM

I just ordered up the eMS-Pro and wiring harness and would like someone (or all of you, actually) to let me know if there's anything else I need. Sorry if there are answers in the posts that I haven't looked at yet (I am reading as I go along), but I have precious little time to get everything ordered before I go home on leave. I spoke to Matt at DIY and in addition to the eMS-Pro, he recommended I get the MSD DIS-2 (so I did), the ford CAS (haven't got that yet), and a wideband O2 sensor (just ordered). Will I also need;

Boost Controller?
A/F Gauge?
Ford CAS?

If there's anything else you guys can think of, let me know... I'm not totally mechanially inept, I've just never tackled a project this in-depth before.

First of all, that is a really nice unit you've ordered there. Interesting that you went that direction seeing as how new it is though. If you ordered just the wideband without a guage (such as the LC-1) then I would probably get one so I wouldn't have to rely on having a laptop hooked up just to see the A/F ratios. For boost control you can just purchase the GM solenoid and pigtail - GM boost solenoid for Typhoon, GM Part # 1997152 Pigtails, GM Part # 12102747. It'll take a bit of testing on your part to get the settings dialed in though. Otherwise you may use any form of aftermarket boost control you'd like. You will also want to get the GM IAT and CLT sensors. I'm guessing this unit is using the MS2 chip (I could be wrong) which is why they are suggesting you run an MSD/Ford ignition setup seeing as how the MS2 MSnSE software is in the alpha stages.

No, its an MS1. No idea why he's suggesting a ford CAS. They probably don't know that there is a decoder for the NGC crank. You'll need to make sure its setup to handle a hall sensor input and can do spark outputs (for the $ it should).

Ah okay. Should have figured with all the features advertised that it was in fact an MS1. It seems it's required to run external ignitors though which from what you were saying is superior to the internal ignitors.

boost junkie · 06-06-2007, 06:26 AM

Honestly I think the internal and external ignitors are electrically the same but the MS board is susceptible to electrical noise so its better to keep the high power transistors off the board. However, that's a completely different subject than the spectre

Post all of your troubles and findings. I planed on getting the ems pro and would like a how to or a sticky for this. This unit is brand new and people will need all the help they can get. If i get the unit soon, I will post my findings.

boost junkie · 06-06-2007, 10:46 AM

I suggest buying a box from rs-autosport.com. It's $400 cheaper and is setup specfically for the neon/srt-4. The spectre box is way over priced for an MS1 IMHO....

DarkDangler · 06-06-2007, 10:55 AM

Thanks for the help, gentlemen. I've still got a little more fact checking to do. If I have any more questions, you mind if I pm you guys? And to the other guy, I will be listing my progress here as I go along. Thanks again.

i saw a srt 4 pull 350 to the wheels with the eMS-pro on it, and that was on pump gas.

What code was it running?

You must have been at St. Louis NOPI!

BoostJunkie, there are a few things you missed about our "overpriced" version of the MS. We have made significant design changes to reduce susceptibility to noise, ground loops, etc. We include native USB (not a USB-serial adapter), and a warranty on the unit. Also, our box does not require the user to open the case and use a soldering iron to switch ignition inputs, install output mods, etc.

If you guys don't mind, I'll be glad to help get the emspro running on adambaum's car here.

Also, we're running a customized version of 029w MSnS-Extra on our box currently.

adambaum, post up questions when you are ready. You don't NEED the DIS-2 but it makes a nice hot CDI spark. You can also go cheaper and use DSM ignitor and 4-tower coilpack that fits your engine better, if you like to spark on a budget. DSM coils are some of the hottest OEM coils we could find.

Any other questions? post up and I'll answer, or come to the spectre forums and ask there. Don't worry, we'll make sure you get the engine running,

For the cost I would like to see ms2 cpu, beefed up integrated IGBT circuit, PWM hardware injector drivers, etc. I like the idea, however the MS1 cpu turns me off. Especially since ms2 is really coming along fast (sequential injection soon!).

I agree with you, I'd love to see an MS2 version with USB, warranty, free tech support, etc. for even less than $800.... but the reality of production and parts costs wouldn't allow us to do that very long.

Also, when we started development of the MS1-based version, MS2 didn't even have multiple spark outputs (about a year ago). Meanwhile, MSnS-Extra MS1 unit compares in features to many other standalones, and there are still quite a few things missing from MS2-extra that kept us from going that route.

And finally, sequential EFI on the MS2 is a bit farther away IMO than you may expect. Market research on my end shows that commercial standalone users are more concerned about sequential COP ignition control than they are sequential injection (I'm only seeing guys at the 8+ hp per cubic inch level that are needing trimmable fuel per cylinder, raise your hand if you make 8hp per cube, meanwhile we can't run an LS1 native ignition because of no sequential spark over 4 cylinders).

From the position of an intrepid MS developer (you), I see your perspective exactly - I know, because I have spent a lot of time assembling and tuning MS1s, MS2s myself. But from the commercial perspective, where we're up against Holley, Bigstuff3, etc. - the MS1 Extra platform is more developed & stable, and more competitive for the price, to these guys.

Just to be clear, if someone asks me about EFI and where to get started, I point them to assembling their own MS1 or MS2, and if they aren't comfortable wielding a soldering iron - we built the emspro for those who don't feel confident doing things the normal MS way...

turbogui · 08-25-2007, 12:59 PM

You price is OK, there a lot of R&D in this product. I have take a look on and congrat! A Good way to go for the one who are not confident whit electronics.

Again, nice work!
