@D0nny94
do you have any info regarding connecting the PNP?
perhaps post some images of connectors, or a link if you has a positive one.
I guess what I'm really after is are you plugging it in correctly, as its still showing weirdness in the log at the moment. However, you still have wires to cut, and those additions were for a different board.
Looks just like this i cut my links out to see if cam signal returned but it didn't
so ill have to re apply them however none of them go to cam sensor the links i added did fuel pump and coolant fan
Ecu Plugs straight in so no adapter boards
the guy who asked a while back sent me this on facebook so i will do this tomorrow
Speeduino pin out mod to suit 1994 1,8 BP engine:
V-ref moved from 1N to 2K with pin 1N cut.
i haven't put this link in before so if anything this is the fix but i dont understand what its doing
Tps signal are same 2M but I did cut 2L as it is rear heater vindow
relay. Already done on pcb remove relay in boot or cut 2l ..... My Tps is not working
Fan moved from 1R to 1L with pin 1R cut.
fuel pump moved from 2O to 2T with pin 2O
The ECU has 2 ways to control the fuel pump on an MX5, the primary way
is by toggling 12v on the ST_IGN line, the alternative way on
different setups is using pin 2O (Like you were trying to).
All that should need to be done is the fuel pump pin in TunerStudio
should be set to A9.
Sorry I didn't realise this sooner.
I'd advise jumping the fuel pump in the diag box during the initial stages as that was tricky to get working
It's been a while since I've sent/helped with that. But i hope it helps.

That's the method mentioned, it grounds what the MAF flapper would have
so you need a jumper in the MAF plug and speeduino uses that
As for the tachometer.
If you do need a tacho out.
The 1.6 does not take a tacho feed from the ECU so in v1.0 there is no
provision for that.
Firstly does the tacho not work at all as it is now, as on some 1994
cars the tacho pin on the ECU is actually an input from the coil pack
as feedback.
It can be seen on one of the diagrams here.

It does require a small internal modification and adding of a
resistor.
You need to run a small wire from the pad labelled LS1 on the board to
pin you want to use for tach out.
You'll also nee to add a 1k resistor between that chosen pin and 12v.
Then set the tacho out pin to 49.
I can provide pictures if needed.
