Managed to upload it this time.
It's quite odd as I replied with a MMS to the number you used to SMS me.
It comes with all shown in the picture plus I will get a USB for you with the base 1zz na map and base 1zz turbo one
As I stated in my other thread, it either has a very poor base map or one or more of the wires in the PnP harness is incorrect as it would always misfire bad with any load applied and also would refuse to rev over 3500rpm in neutral but as I really have no idea how to tune I kinda gave up.

Now that I have a Haltech elite 1500 in the car I believe it is a very poor base map as I have the exact same cel codes that both ecu caused when they controlled the motor

Not included in the pic is a folder with the instruction manual for this unit.
If I find it that is also included

As far as I'm aware it just needs to be plugged in and tuned, it has a very poor starting map on it for a turbo but I should might have the Na base map it came with somewhere.
It also comes with a map sensor so that will need to be installed also as the ems4 uses map instead of maf.

I tried to upload a pic but it keeps getting stuck at 54%. Got another way for me to send a pic of it?

Hmm, that's a good question and one that I'm not 100% sure about but I think you would have to change a few wires as the SMT spyder and MT spyder do have a different throttle body set-up

I still have it and judging from the lack of interest in it will properly have it for a while.
Drop me a pm if you are still interested in it and if I still have it

Hi all.

I have decided to sell the EMS4 I brought for the Spyder as I'm taking a different route (converting to E85) and as the EMS4 does not support flex fuel it has to unfortunately go.

It has been installed in the car but has never been tuned and only has a base map installed.

I will be leaving it in the car until I sell it so the buyer can see it works on a SMT spyder.
If your Spyder has traction control and stability control those will be disabled unless you wire in a 7.5 ohm resister to fool the stock ecu into thinking it still has control of the VVT-i as only the ems4 is wired up to see the oil control valve that controls said VVT-i and any CEL will cause those systems to be disabled

This ECU will work on any 4 cylinder with any aspiration as long as the fuel is not E85. The included PnP harness is for a Toyota MR2 Spyder with the SMT but the harness should work on any 1zz or 2zz powered car with a few wires changed or added (For 2zz cars), any other engine may require the harness to be either heavily modified or scrapped

Below is a link to the company I purchased the EMS4 off

https://monkeywrenchracing.com/product/mwr-aem-ems4-ecu-kit-celica-gt-00-05-gts-00-02/
Looking at the description it might be possible to put a 2zz into a spyder and keep the SMT gearbox but I am unsure if anyone has tried as of yet

I'm looking for $750 but Ill sell it to a fellow MR2 owner for $500
