EMB Reversed signals!!!

[ake1ro]

Hi!!
Nice forum! I know some of you from emanage forums!!
I hope you're ok!!
Now!!!
I've got some kind of problem!!
Im using EMB with injector harness, bigger injectors, ignition harness, GReddy map, bigger fuel pump, on mazda bp 1.8 dohc about a year ago to 1 bar! Everything's fine!
The thing i wanna know is why my AFR signals are reversed!!
When i put -1 the mixture is rich and lean with +1!
Same for the ignition!
Answer will be appreciated!!
Thank you

Welcome back to the community ake1ro.

Is this the same car as you were using a year ago?

My next question has there been any sort of electrical change to the car since just before the problem started? Jump start? Floating ground? What it sounds like is your circuit got flipped as a result of an electrical short which can be remedied by disconnecting the battery for awhile and then reconnecting. This should reset your circuits if that is the problem. If that does not work then we will start narrowing it down.

Again Welcome back =)

Hallo my friend!!
Yes!! Same car more power!!!!
This "problem" it was from the beginning! Not now!
All the wires are placed the way it should be!(Triple checked)!!!
Its not big deal though cause is working fine but.. reversed!!
Is there a way my resistance dead? All the mazdas need that resistance right?

Hi ake1ro,

I did not have to use the resistor for my 1.8 bp miata. What are the rotary switches set to? For mine it's 3 A 0. Also, you might try asking over at miataturbo.net. The guys there know the BP engine better than anyone but mazda. (Not trying to redirect away from the forum, but the emanage section there is pretty good, and posting in the diy section will always net something helpful).

3 A 0 yes!!
About the resistor... using it or not cant say there's a difference on my car!!
I'm going to check it out.
Thank you

Your not outdated. We just need to find some people that are having wiring issues. Actually i have an idea for the forums that maybe you can help me with will pm you so we dont jack this thread.

I'm in the process of wiring up my 99 miata and everyone says to set it for 3 A 0 but isn't the first one for how many cylinders your engine has? I'm not rolling a geo metro damnit.:rolleyes:

Anyone got an explanation on that one? 4 A 0 instead of 3 A 0

oh, and what size resistor are you guys using?

[Accord2nrz]

no becuase my rotary settings are 2 8 A and I have a 4 cyl engine.
