Which way does electricity flow? From GND to + or + to GND?

From the out side to inside.

I need a little help. I'm on the very last part of my turbo install and think my megasquirt is giving me some troubles. Basically, the fuel pump is not priming when I have the megasquirt plugged in and turn the ignition to the on position. However, when I plugged the stock ecu back in without the megasquirt in the system, the car is fine and the fuel pump will prime. I misread the instructions and grounded out the grey, brown, violet, and green wires since I am not using them. Even when I taped them off and took them off the ground, the fuel pump will not prime and tuner studio will not even recognize the megasquirt. What should I do?

blown fuses?

What worries me more is that you had the top and bottom harnesses swapped.

Do you have a digital multimeter so that I can give you instructions on what to check?

No, just tape them off like I told you.

Electricity is like water, it flows from the point of higher "pressure" (aka voltage) to the point of lower pressure.

Gnd is effectively 0 volts, so it will flow from 12V (or 5V or 3 or 1.5V) to 0V, aka ground.

I did then was 1/4 trololololol on hustler and brain.

Yes I do. Just let me know what to check :)

Ive now read all 309 posts in this thread and my resulting erection has lasted for more than 4 hours.

I have already contacted Reverant, but should I also contact my physician?

Thanks.
While waiting for the part to arrive, can the ecu be hooked up with the vac/boost hose running to the port in the box. So it receives the signal that it needs, but it's not controlling anything yet because the manual boost controller is still being used?

Yes, no problem with doing that. It just won't control the boost.

Well, after over 40 emails back and forth, Rev was able to figure out my problem :). Thank you so much for the amazing support!

Hi Reverant, I'm looking to ditch this Hydra Nemesis 2.5 EMS for the MegaSquirt. The Hydra wideband isn't working and their replacements are freaking ridiculous @ $450/each and they do not allow you to wire in any non-proprietary wbo2 like my LC-1 wbo2. Tired of dealing with trying to tune out the little kinks with this ECU.

Are you still waiting on any outstanding orders from the current batch? I removed the supercharger from my track Miata last year; do you have base maps for a stock 99 Miata or is this directed to the boosted folks only?

The wideband issue with the Hydra is a major pain in the ass, indeed (speaking as an ex-Hydra owner myself).

I'm still processing orders from the group buy, however I am taking new orders as well. Current lead times are 4-5 weeks.

Dimitris

You doing anything with MS3 yet?

Do I have an ETA yet for my early 1995 car? Is there anything else I need to do to verify the "earliness" of my 1995 aside from counting pins on the coil pack? I'm still planning on putting this computer on the stock, early 1.8 engine and swapping the VVT engine over using the CKP and 2001 CMP.

I do plan to migrate from the MS2 to the MS3. If you need to purchase in less than a month or two, go ahead and build yourself an MS3+MS3X. If you can wait, then I promise you that I will be totally worth the wait.

Dimitris

As far as the group buy is concerned, right now, I only have one paid unit that I haven't shipped out yet, all the rest are not paid (I have not requested payment) seeing that these units do take longer to manufacture than anticipated. In other words, I can't give you an accurate estimate - lets say in two weeks time.

Having said that, I do not have a problem if you want to get an MS3 instead on your own - I have enough orders to keep me busy for a while.

My car needs to be running on whatever by early April. I'm debating upgrading my MS1 to MS3x (leaning heavily this way) or maybe even going AEM to avoid any more "building". I'd rather drive.

Hi Dimitris, do you have received my PM with the informations for my car?

Thank you ;)

You ECU has shipped with UPS; France no longer accepts EMS so I could only ship with UPS. I expected you to have the ECU today, let me know if you don't have it tomorrow.

Dimitris

Upgrade to an MS3 now to have your car ready and fully running by April.

I know I asked earlier, but with the launch control, if I were to hook it to a switch would it constantly limit the rpms with the switch grounded out? Or is it only when the clutch isn't engaged? I just don't fully understand how it works.

Exactly. Use a momentary switch to achieve a proper launch. Hold it down when you want the RPMs limited, release to launch.

Keep me on the list, please.

I'd like to start running MS2 on my daily on the stock early 1995, but convert to CMP/CMP from a 2001 in a few months. This is only settings and external wiring, right?

So I've been researching and apparently with the AEM unit for a 9093 car they simply cut into the brown/white wire of the clutch switch. That takes care of grounding out the launch control switch. Does the flat shift feature also work off of that switch?

Edit: I'm simply trying to make the flat shift and launch control work without having to use a toggle switch.

Yes, that will work with the MS as well. I would still advise to use a master on/off switch between the ECU and the clutch switch.

So yellow wire to toggle switch to clutch sensor. Seems easy enough. Thanks for the clarification, it took me about 3 hours of searching to find that info, and I couldn't find any to confirm it so I just wanted to hear from the horse's mouth.

GREY wire. The yellow wire is the wideband input.

Sorry, at work on break, going from memory.

Want to tell me how to do sequential now that it's up and running?

Megasquirt is arrived !

Thank you Dimitris ;)

This look right for wiring up a switch and LED for the EMS?
https://www.miataturbo.net/attachmen...ine=1327199568

You will need a resistor before the LED+. Is this to activate the switch tables/launch control?

Yes. What resistor?

For normal LEDs, a 1K resistor is fine. For high brightness LEDs, a 680R is needed. This assumes that the LED+ is connected to 12V.

Hi i just found this post is the group buy still open and if so how much for a 2001 1.8

I have sent 2 PM's, Please let me know when you think you will be finished with the megasquirt. Just looking for an update.

All PMs and emails replied.

Pm'd about a unit.

To the few members whose ECUs I still haven't built nor collected payments:

• MINI-P (99 1.8) mt.net
• kingkong15 (2004 MSM) mt.net
• Kingspeed (2004 MSM) mt.net
• hustler (1995 1.8) mt.net
• midpack (2004 MSM)
• slopokes123 (2003)

Please PM me if you still want your ECU. It has been quite a while since you declared interest, so I would like to know if you still want it or not, so that I can arrange it.

While on the subject, after jeff_man's recommendation, I've made the adapter harness longer. The ruler is in cm.

https://www.miataturbo.net/attachmen...1&d=1330850741

I put half down months ago. Should I be on that list?

No, I keep separate lists for the GB people and the regular orders. You are 1 ECU away from being built.

How long does it take to get from Greece to the US?

If you lookup the tracking number I sent you (use USPS' track & confirm), you'll see that it has landed in the US since Feb 28, and is in US customs.

Thanks! I tried looking it up, but it's in Greek. I couldn't figure out to view the details in English.

Hustler just got done making the ecu work. Seems Ve auto tune does not work with it. Going to pull the harness and make it longer sometime this week.

I didn't "make the ECU work", I got my head out of my ass.

I wouldn't say "VEAL doesn't work". I'd say "don't rely on it the way I have in the past". I don't know enough about VEAL and tuning in general to criticize.

You made it work because I didn't :giggle:

MS2, VVT controller, adapter harness for 01-05:

https://www.miataturbo.net/attachmen...1&d=1331152107

I will say that is pretty ------- sweet looking.

Dimitris,

I'm sure you're super busy, but if any of the guys on the list for the MSM ECUs fall through, I'd like to jump on one for your regular price if it's possible or would help you out in any way for parts you may have already ordered.

Thanks

I want that. Can you add that to my order and will it work if I don't run VVTuner initially?

My order finally cleared customs today :)

I am on the list for my MSM euc too. have not seen anything yet....
Any update ?pls

How long? I'm getting impatient.

11 days in customs. It got to customs pretty quick, I forget how long. It was definitely in customs longer than it took to get there from Greece. I imagine it will show up mid next week...

PMed.
