Please lets keep this thread clean. The IAT sensor is not included, you need to get that seperately.

Staffah (Canada) 2000 NB with MP62

Out of curiosity, if I add COP's in the future is it just a mater of changing some values in the software?

COPs will have to be prepared beforehand so that there will be a minimum of fuss when you decide to upgrade. By going to true (sequential) COPs you will lose the ability to change the temperature that the fans will turn on as these will have to be moved to the extra board that we provide.

The main difference is that you can go fully standalone with this unit, and the firmware is open to development and getting better all the time. The support from the Megasquirt community in general (including this forum) is astounding. The only two major advantages of the Adaptronic as far as I know are VVT control and the "timing advance autotune".

So this is full standalone, whip out the OEM ECU, plug this baby in and turn the key? Will it ship with a base map enhanced for whatever year car you order for?
Also I have a wired IAT sensor connected to my MS-1 s all I would need to do is wire this to the IAT input on the MS-2? Is the MS-2 configured to use Mazdas CLT sensor so I can rid the GM unit I've plumbed in?

I've got a UK 1998 which is an NB. They didn't release the NB in the US until 99. I'm guessing I'd need a 99-00 build. Can anyone confirm?

Yes on everything. You need the 99-00 unit.

Specifically, you will replace the car's plastic IAT sensor with the GM open element (which I am guessing you have). The unit is plug and play, which means you can use the stock plastic sensor IF you want to, otherwise I would recommend that you replace it for FI applications.

If it is an NB and not VVT, then you need the 99-00 version.

Is it wired into the MS-I through the stock harness?

My GM open element ait and 3 bar MAP sensor I got from diy autotune that I'm currently using with the Adaptronic will work with this right? I don't see why not but thought I'd ask anyway.

Also will I have to re-wirethem elsewhere into the system, or will they work in their current configuration? (ait is a no brainer, but the MAP sensor us Adaptronic users have wired in so that signal is coming off green wire that would go into the MAF sensor and + and Gnd are tapped into TPS wiring)

Just curious, why are you switching from Adaptronic to MS?

If you let me know exactly where have spliced them on the stock harness, I can make it happen, no problems there. FYI, on Mk2.5 cars, I usually place the GM 3bar sensors in place of the stock barometric pressure sensor, which provides a nice location for the MAP sensor and exactly the 3 wires I need: +5V, GND and signal out.

It is an NB without VVT. I'd use my open-element GM sensor though.

No.
Currently my MS-1 is running both the CLT and IAT GM sensors wired separately from the factory harness. The OEM sensors are still wired into the factory ECU as they are still needed for the stock ECU to do mundane stuff.

One more question, what provisions are made for the OEM immobilizer? I'm not bothered if it doesn't work any more under the control of MS2, I just don't want it to prevent me starting the engine or get in the way.
My car is also without AC, so I guess this isn't an issue - I just won't benefit from all the AC goodies you've put in?

If it's any help, my factory ECU is labelled "BP5C".

Craigo, I've replied to you on the nutz forum. Long story short for anyone else looking for the same answer here: The immobilizer continues to work properly.

Interesting, since I've never heard of a stock barometric pressure sensor on our cars (though I THINK i know what you're talking about). Your way actually sounds even better. Where is this sensor located? Is that the one that is next to the EGR equipment/charcoal cannister?

Your way actually sounds simpler. if you have a picture of one mounted/hooked up on an NB that would be FANTASTIC.

No big reasons, just a few little ones:
-DIYPNP doesn't require a bulky harness, but just swaps in replacing the ecu. No extra wires or anything unneeded.
-From what I can see MS has MUCH MUCH bigger support and user base. Adaptronic has a very limited user base on here (even though all the guys running them on this forum are GREAT and super helpful).

Tha'ts about it.

Oh and just cause I want to try something different and see how the two compare back to back. if I don't like it I'll sell it, and if I do I'll sell the Adaptronic.

That's cool. I would be interested to find out how they compare, thanks.
