Re: Nissan on Frankenso #47
Can you send me your Honda TS project so I can try your settings in my car? I want to element ate the possibility that I am doing something wrong here. Tune is really out of date with current version, a lot of config-breaking changes since then. I'll take a look at the tune, and I'm sure a few othe...

Re: Nissan on Frankenso #47
See my edits above, your setup is already more than sufficient to run full sequential fuel and ignition. I'm having a hard time articulating this, but I think the part you have wrong is thinking that more precision is better, when that's not necessarily the case. I'm not familiar enough with the mat...

Re: Nissan on Frankenso
How can an engine work on guessing game between 180 degrees and pretend to be accurate? Are your all other engines like this?

Re: Standard NA6 Miata 89-93 Configuration
I've seen some discussion on other forums saying that many IAC solenoid valves have a built in air leak at 0% duty cycle, and are meant to be at some nonzero value to be completely closed. Something about a failsafe if the valve loses power.

Re: 88 Toyota Camry 2.0 (3SFE)
Although I suppose it depends on what side of the head you put the dizzy.

I don't have a good source for the angles, but luckily we...

I've done a lot of research on this over the past few years, so get ready.

Honda "4+24" was a side effect of trying different combinations of the three Honda signals. I am not sure if that trigger is enough to synchronize and identify your exact shaft position Honda wheels are evenly spaced. 4+24 can get you running batch fuel, but no sequential. No idea if the ...
Re: KICAD
For Windows builds kicad bundles all the dependencies in the same folder so it's pretty self contained.
As for Linux, it will probably not be as easy, considering the work I had to do to go back to 4.0.7

Re: rusEfi Use Scenarios for Next Hardware Iteration
these are bad examples - I believe these features have nothing to do with hardware. factory narrow band 02 sensor is just a universal analog input and EGR and EVAP is probably just a generic low side. I don't really mean these examples in particular, the same could be asked about AC control, MIL, o...

Re: rusEfi Use Scenarios for Next Hardware Iteration
In PnP applications, what sorts of OEM features are we planning to support? Do we want to support factory O2 sensors? What about EGR valve? EVAP purge?
I guess what I'm trying to say is, how far do we go? What about features only on some models of a much broader range?

Bit of a side question, but do you have a hot air gun? If not, they're totally worth it. $30 on ebay plus $10 or so for a syringe of solder paste and you'll wonder how you got along without it.

Something I would like to pursue is VTEC w...
