I've been searching the web for the last two days trying to work out how to go about doing this without much luck. If anyone can help me with this issue i would appreciate it a lot.
So to begin with I have a MM9495 ECU these supposedly can only be used with the 94 - 95 models.
My MX5 (or miata) is a 1990 1.6ltr Manual, no A/c No Power Steering - this may or may not make a difference
I've looked at the pin outs and i've come up with this picture below:
Now i have a few questions on how to repin this so i can get this to work on my 1990.
Also forgive me in advance as electronics aren't my forte.
On the 95 model what does this data link do? Is it the same as the 1K on the 1990 (Igntion adjustment connector)
On the 95 this is the radiator relay, to which wire should i splice this into on the 1990 harness
How should i connect the VSS sensor again to which would i splice?
Is this needed? or can i just disable in the ECU to make things easier
2H & 2R
How would i connect these? Would i have to change the injection system?
Am i right in thinking that i would just have to repin/splice this to the 1R
Heated o2 sensor Vs Standard o2 sensor do i have to change the o2 sensors?
i'll also be using a LC1 wideband if that makes a difference
Where would i connect this too?
2U 2V 2Y 2Z
These are all per injector 1-4 respectivly. where as on the 1990 model 2U
does injectors 1&3 and 2V
does injectors 2&4
is used by the Transmission control model
So please tell me what i need to do to get this to work. This is not my daily driver so it can sit in pieces while i get things done.
Thanks in advance!
