What it looks like, adjusting RPM up and down, activating A/C.

I have an spare 1998(99) 1,6 euro ecu here, including 1 key, the lock and the immobilizer unit. I could send it to you if you would be interested.

Absolutely! I'll cover the shipping, I don't need the lock, just the ECU, immobilizer and key. I already have the coil (antenna) that reads the key. I'll PM you my shipping address.

It already does.

At least, it does it you have your cranking RPM configured properly.

At least that explains why the OEM ECU cranks and fires so quickly compared to the MS.
?

My MS1-equipped car fires up at least as fast as one with a stock ECU. You gotta wait about a second after switching the key to "ON" before continuing to "START", as it takes some time for the ECU to boot up, but that's about it.

The MS2 fires all injectors simultaneously during cranking...if you have untimed injection and not sequential injection. Booooh.

Btw the MS1 did start the car as fast as the stock ECU, as it didn't wait for a full sync on the wheel pattern AND it fired all injectors simultaneously as well.

MS1 does not = MS2 :P

Seriously?

(I mean, I know that MS1 MS2, I just assumed that this specific behavior was so fundamental in nature that its inclusion in MS2/MS3 was axiomatic regardless of injector timing or configuration.)

It would be interesting to see what the ecu does to fuel and spark by atifically altering the atmosphereic pressure it sees.

Btw did anyone one that the 90-93 ECU does barometric correction? It has a baro map sensor inside it...

Some region cars do, not all. That baro map sensor isn't always populated.

Read about it on the 'slocketing ECU' thread on m.net

Interesting. This ECU came out from a euro-spec 91 if that matters.

The Adaptronic can do batch fire when cranking too, which seems to help.

I have a JDM 99 ECU that has no EGR and runs fine without any emissions stuff, so if you get stuck hit me up! I'd love to know how the OEM ECU is dialled in!

The $1,000,000 question is whether it needs the immobilizer to work...which would it make significantly easier for me if it doesn't need the immobilizer module.

I don't think it even has an immobilizer, my key is just a chunk of metal??

Message me your email address.

The ECU is currently running my race car but I may be able to get my hands on a spare tomorrow. I'm flying to London on Saturday so if it works out I will post it from there otherwise you will have to wait a couple of weeks.

Cheers

What does it do for fueling with high intake temps, especially after startup?

I haven't been there yet, I've extracted all the data on cranking PWs at various system voltages, and a single running PW at 250rpm and almost zero load, again at various voltages, coolant temps and time stamps. This is a really long and painful process, as I have to change multiple parameters by hand (ie potentiometers) and then measure with the oscope, switching between the stock ECU and a MS to measure the parameters I am sending (CLT, IAT, RPM).
