first rusEfi dyno run. Stock ECU run: 121hp/127 lb-ft 1st rusEfi run ever - wooping 44hp/69 lb-ft. Right, 12 degrees advance does not work so cool 8 runs later: 123hp/128 lb-ft. More then stock ECU! better timing. We did not tune fuel at all (Speed Density with default table), the plan for the day w...

Is not this BIP373 low side (N-channel)? It looks like I would need a hi-side for alternator control.

My electrical engineer is busy at the moment, I hope he gets back to me or I would order FQB12P20TM just as a random P-channel

I wonder if you could use a mosfet to handle the current. The rusEfi control could switch the mosfet for PWM. I am using a mosfet right now - TC4427 - but looks like it's just too weak with it's 1.5A peak rating. What's your favorite mosfet for this application? I have a DPAK breakout module I can ...

Are the voltages above actual measured at the field connector, or just mathematical equations? that's actual voltage measured on my control wire while it's not connected to alternator (the pieces are not connected yet since I am still trying to figure this out) I've removed the 100R resistance but ...

It's hard not to understand electronics, so far I am failing to control the alternator with my ecu. Here are the details: Resistance between field wire and ground: 12 Ohm With the car running with rusEfi, if I manually connect field wire directly to battery positive terminal I can see how the car RP...

might be easier to go with an external regulator

Great link but they do not specify if 1st gen or 2nd gen

Looks like 2nd gen the wire goes to battery, not ground.

Does anyone know anything about alternator field wire? Is it ground or battery +, is it on/off or PWM?

So my 2ng gen does not have a timing mark right? I've made my own mark more or less where TDC should be - that's the longer mark. the other marks are 10 degree apart (at least I hope they are - 16mm should be 10 degrees considering 93mm pulley radius) http://www.youtube.com/watch?v=QHzr-K8jmqA that'...

When I've started this two years ago I did not realize that making an ECU from scratch would take so long. At this point I am just enjoying this as a hobby, hopefully I will run this ECU at a Lemons (amateur endurance road racing) race in 2015 or 2016. We'll see :)

2003 sxt - rusEfi test mule

My 2003 sxt is a test mule for my open source ECU project. http://rusefi.com/images/forum_posts/dodge_neon_2003.jpg I hope I've got a great deal - less then $1k for a 101K miles manual with current inspection. Looks like there was a hit into one of the rear wheels or something since the bearing and ...
