Re: EcoBoost V2 in Jerry (Miata NA 1.6) #47

Re: Standard NA6 Miata 89-93 Configuration

It doesn't, but it turns out that isn't necessary. The barn-door style AFM (as well as hot-wire MAFs) measure mass flow rate, not volumetric flow rate. IAT and baro pressure are already accounted for! The hot-wire MAF indeed accounts for IAT and baro, but the barn-door AFM doesn't, it does measure ...

Re: Skoda 120L + ITB

If russian is up for it, I think that support for multiple maps is the way to go. AKA tune each cyl individually. Think of it like 4 ECU's in one, but with one crank, and one temperature sensor, etc. What problem are we trying to solve here? I'm a big fan for keeping stuff as simple as possible. Mu...

Re: Standard NA6 Miata 89-93 Configuration

Sweet, this would be a great step for RusEFI. I'm a bit worried about the AFM though: it's very sensitive to transients in airflow. Just hookup a scope to the AFM output and move the TB quickly. If we have a big board anyway, why not add a footprint for a 10$ pressure sensor and skip the ancient AFM...

Re: Skoda 120L + ITB

MAP has mixed results on ITB engines because of the very short runners with low volume. Some engines are tunable with MAP and ITBs, some keep struggling. Rusefi does have great options in software for MAP filtering (you can select min-max/avg/at a certain angle), so you have a fighting chance. Usual...

Re: 2001 Mazda Miata - Engine #46

You could also put the DMM in current sensing mode and connect it to Gnd - signal and also 5V - signal. See how much current flows when forcing a voltage, should be very low. Another possibility: one lead of the DMM to the TPS side of the wiring, other DMM lead to the pin on the opamp on which the s...

Re: 88 Toyota Camry 2.0 (3SFE)

By far the easiest way to invert a signal is by using a buffer transistor. Since you only need to control the input of the TC4427 you could use a tiny small signal MOSFET/BJT with a pull-up on the drain/collector like in the below schematic: main-qimg-d49bd7ccd25f9fd159be7c8a3dbc5a34.png No need for...

Hai guys! Number four is indeed usually a bit low but yours is okay. First compression cycle numbers aren't very useful because the engine doesn't always stop at the same point. It may already have been right before the compression stroke on the "50" reading, which doesn't give the starter...
