If you decide to go trully sequential on the ignition, then you need to change the wiring on the COPs. So far, you have cylinders 1&4 and 2&3 tied together brought in to ignition A and ignition B through the stock wiring harness. You will need to split them, and bring coil 1 to ignition A, coil 3 to ignition B, coil 4 to ignition C, coil 2 to ignition D. Ignition C and D will be waiting for you on the DB15 connector, ignition A and B are brought in as usual through the stock harness.
To go back to wasted spark, you will need to disconnect ignition C and D from coils 4 & 2, and reconnect coil 4 with coil 1, and coil 2 with coil 3.
You will receive instructions on how to do that for your units.
Please note that a unit that is received as wasted spark CAN be converted to COPs without reflashing of firmware or anything, but you will need to move the two wires that control the fans from the MS to my own board - a 5 minute task. You will not however, be able to adjust the fan temps, as your board will come preprogrammed with the default values (200 for the main fan and 208 for the A/C fan, 6 degrees of hysterisis on both fans).

Rotrex requires dual throttle?

Payment done.
450$+30$ for the IAT
It had a payment fee of 4.80$, but no matter, it's like having two beers outdoors

Payment sent! I've sent $470.
1998 UKDM 1.8NB with PS, VICs and no AC.
I have added $20 for an open-element IAT sensor without a bung.
In terms of customisation, I want to run the MS-2 with enhanced features, VICs and fan control. I might do COPS at a later date once I get hold of some.
Thanks again for organising this group buy!
CRAIGO.
p.s. I take it these units will come with a document listing what mods are on it and also how to convert to sequential spark with COPs? It would be great if that is the case

I am pretty interested in this but have no idea what COPS or IAT are? I am 29Guy off MX5NUTZ.
My car is a UKDM 1.8iS NB 2000. It has VICS and power steering but no air con. At the moment I'm staying Normally Aspirated but plan to go Turbo or S/C in a couple of years (maybe).
I guess all these extra features could be added at a later date? And still retain the OEM plug?
If I did decide to go for one; how would I go about paying the $450 initial payment?
Cheers

EDIT. It's definetely a mk2 and not mk2.5 btw. Thanks

OK
I really am a newbie and still don't know what Coil on plugs means, is it something to do with the Coil Pack? Which replaces the distributor on older cars?
And Air Intake Temperature; is similar to the Manifold Air Pressure sensor that replaces the stock MAF sensor?
I have sent Reverant a pm as he is in Europe and I'm in the UK, but if I decided to, could I send the payment to you instead - not 100% yet but it sounds good. Is it PayPal or bank transfer as my online transfers seem to take about 3working days to go through, etc.
Thanks

It replaced the stock coil pack with individual coil packs without plug wires; they sit directly over the plug, hence the name. They have a better spark output than stock coils and there will never be need to change the ignition wires again. This is not a necessity by any mean and you can always upgrade later.
See under useful saved posts: upgrading to coil on plugs.
the AIT simply reads the intake temperate, the air pressure sensor reads the pressure. It's the only thing within the MAF we need to bother with, so we typically replace them with the GM unit and remove the the restrictive MAF. They are "open-element" which updated the MS of any changes in temperatures much faster than the stock sensor.
I'm taking Paypal payments.

Just sent you a pm, I'd like to order one then please.
Would you recommend any specific options for my Normally Aspirated setup? I would like to eventually fit a Flyin Miata Turbo in about 2 years but at the moment all I have is: -
IL Motorsports short-intake Cold Air Induction kit (same design as JR CAI but for mk2)
Racing Beat 4-1 header/exhaust manifold
Flyin Miata high-flow CAT and resonated midipipe (no middle silencer)
MAZDASPEED backbox
Magnecore plug leads
Uprated plugs
Will be getting the standard injectors cleaned soon
Is the 'GM unit' that replaces the stock MAF included in the price? What about the sensors; seem to remember reading there is one built into the ECU?
Sorry to keep rambling/repeating jusy want to get my order right, etc.
Cheers

Guy, for a naturally aspirated NB, I wouldn't recommend bothering with changing the factory air temperature sensor, it is just fine. If and when you go turbo, then you can fit an open element IAT sensor.

Argh I'm so confused... If I fit this extra AIT sensor and bung does it mean I can do away with the stock MAF and stay Normally Aspirated?
Thanks as always for the advice

Think I'm beginning to understand; just need a vacuum line from the inlet manifold instead of a MAF? So the Air Temp sensor is the little one that usually sits in the cross-over pipe/airbox...

They said it can be done for 89-05 miatas, but not vvt control (01-05 models). If your car is an NA, then you can go ahead in the GB.
