Well the MS2e arrived. Unfortunately without instructions, cd or the USB adaptor I also paid for.
I am not having much luck communicating with Reverant so hopefully can ask a few basic questions here....
I have the IAT sensor and a Innovate MTX-L AFR. Can someone point me in the right direction on how to wire these in to the existing harness.
For example does the Wide Band 0-5v lead go to the existing narrow band pins on the ECU harness?
Where do the IAT leads go? (I don't believe this is a factory option, at least on an 89/90 model, so it can't have an existing pin out on the ECU harness to substitute...?)
I have been through the link in the above post but nothing I can see relates to hardware connection, just software settings....I am sure I am missing something obvious (instructions, manual etc...)
EDIT: Typical, soon after posting I just found a generic hardware pinout table!
- On the megasquirt page they give a v2.2 and V3.0 pinout guide. Does this relate to the Miata harness as well or is this an internal/generic connector..?
Megasquirt 2 - External wiring layouts
If it is accurate to Miata, then
- WB AFR to pin 23?
- IAT to pin 20?
- Do the grounds HAVE to be to the MS harness or can they be direct to chassis?
