Arduino as ECU?

are you just trying to build up your post count??
having read your other posts (all on this thread) I can only imagine you're a non-miata guy and you joined this forum because of this thread. That said, please spend 5 minutes before posting questions to do basic research.

But I do have an Arduino, three of them in fact (a Mega and two Uno) and am a hardware guy. I was reading this thread and got interested.

the rpm enrichment is probably a mechanical design. the wind that is passes through the afm will kick back the plate initially further then the air that is passing through was suppose to be at. it's all inertia i would assume. because it levels out real quick
i'm mean we are talking about a small albeit minor flac that the afm
also a question for whoever had made this graph... did you swap into a full range tps? also can you get us a read out of what it looks like to be 3 k rpm 5th gear cruising down the freeway. i think that's the most important thing about our cars.

woot sorry for the late response myself. i decided to give up on the arduino as an ecu subject. it seems the capability of the unit itself is limited. i also don't have the knowledge to write the code for it. i guess i was just brain storming to see if it's possible. i actually was more interested in it as afm eliminator.
but however i still have no experience in coding.

Is this thread still alive?
I happened to stumble across this forum and post way too late in dev, I have a 91 miata I am trying to use an arduino to control or replace my ecu all together, I have roughly read all of the posts but got lost alittle here and there... so did bloodline loose all interest in using the arduino altogether

Reading a good bit of this thread before I realized it was ancient got me thinking. Trying to use an arduino as a full ecu seems like a bit of a stretch and we're already got good affordable solutions for that already. If there was an arduino variant with 4 high current pwm drivers and 4 vr/hall inputs it would be interesting to try to make a motorsports abs/traction control system with it. Race logic traction control's price isnt too outrageous, but a motorsports abs system is around $10k.

Egads, you just made me feel bad a year later for just joining these forums because of this thread. (building myself a Locost 7 using many Miata parts off of a wrecked non-turbo, a way to save a great car which served me well for many years)

Latest 8bit Arduino code here:
https://sourceforge.net/projects/mia...ataBrain_v3.1/
Will post up 32bit ARM code at some point.

arduino crank and cam simulator
thanks mate just programing another arduino as the crank angle sensor to trigger the arduino efi
thanks will have a look
QUOTE=JasonC
SBB;1139942]NA and NB motors have different cam pulse patterns.
NA are like the old Mitsu motors that have 4 crank pulses per crank revolution.
Search this forum for my posts on the VVT setup. The NB non-VVT and VVT have the same cam pattern, just that the latter moves around.[/QUOTE]
