Hi all, I've got a few queries about running an EMB on my Miata/MX-5 99 NB and I'm hoping you knowledgeable guys might be able to help me out.

Can anyone tell me:

1) Do you need to bypass the MAF signal around the EMB on the '99?

a) if so, do you still need to put the resistor in for the MAF signal?
b) can anyone suggest an outlet where I can get the resistor holder
to hold the resitor in line (I don't really want to solder my ECU or EMB)?
c) I assume the EMB will have to run off the MAP if the MAF signal is
bypassed?

2) Why are there two tables for adding fuel in the EMB manual (Air flow adjustment and additional injection setting)? I can understand that the Air Flow map tricks the ECU into adjusting the fueling by altering the airflow signals, but why do you need a second table to add injector duty cycle?

Does the duty cycle map take care of transient throttle situations?


3) Do I need to jumper my injector cables into the ECU as per the idiot's guide to the 1.6 NA:



Many thanks in advance for any help offered.

 

Awfully quiet in here, am I asking the wrong questions?

 

I dont know much about the EMB but i would say no to bypassing the signal. ever considered EMU

 

I considered the EMU for about 5 seconds, but realised that the EMB can do everything that I want from an aftermarket management system. The only problem is that I can't seem to find anyone to help out with the model specific queries that aren't answered in the manual.

I guess it is old technology and there are better management systems out there, but it seems that if all you want to do is tweak the ignition and fueling maps on the stock ECU then it's ideal.
