yeah the ECU is acting as the regulator, but I am open to any alternative so I will contact abeFM

Can anyone explain these to me ( the dummy version will be ok :oops: ) as I need to understand them a little better. Im doing alternator control via EMS PWM output, so I need to understand this a little bit better, Im just convinced Im going to cook my ECU. And before anyone says it its a cast brack...

Yeah I like JAW but have been told they are a bit high on latency...

has anyone made a DIY AFR controller or recommend an accurate one for use with a EMS?


regards Paul

thanks mk e, I was well aware of that, your input is welcomed I was going to try to avoid signal issues altogether with a ra10 substitute, but had been reading the haltech forum and learned as you just said about try it first. the dual channel board I will still get as I plan to use it as road speed...

the ra10 is only needed if the ecu doesn't get a clean enough signal apparently. still curious if I could have got away with scotchy diode or not, altho I acknowledge your board does it properly. just want to make sure I got this right so bip373 for the IGBTs insulated to heatsink The ECU (has 4chan...

thanks jbelanger I will be ordering 1 of your boards very soon. now all i have to do is find a cheep 4 channel igniter and a WB controller and im set to go... (yes Im looking at your 4 channel inj/igniter board.. is that suitable?) a little info Haltech are an Australian ECU producer with fairly hig...

Hey peeps, The ecu Im using haltech e11 wants a square wave (digital) signal can i do this by rectifying the signal of a reluctor.(as Im a cheap bast@rd and dont feel like spending $400 on the alternative ra-10 dual channel box ) Can anyone recommend diodes to use? or is there a cheap alternative. O...

hope Im not hijacking here Abe (8inch)
but Im interested where you mentioned alternator control, is this the MZR (duratec) engine that is in the miata? and what exactly is the ECU controlling on
the alternator is it on/off or output voltage control via the field?

I had a post in here its gone missing ...hmm strange. Was just a TY to Longracing on explaining the igniters so well. I say they're EVIL as on a high hp engine more power to ya, but I recently drove with a little brother of a friend, the standard heavily worked shit box ...you know full exhaust 5foo...
