Re: 2004 Mazda MX5 1.8 VVT #50

Hi everyone ! After butchering the Proteus soldering I was able to plug it into my car. My harness adapter kind of worked well, I was able to get crank and cam signal and RPM sync, as well as all digital inputs working. Vbatt wasn't working because I did not solder the 82k sensing resistor. I could ...

Re: red 2003 VVT test mule Miata NB2 #27

For referencing purposes so that nothng get lost, here is the MAF transfer tab for 94+ miata. I'll run it but just to monitor flow, nothing more.

Re: Proteus - Waterproof, High-feature ECU!

I plan to order 5 JLC partially assembled boards for now in europe (France), 2 of which I will keep, 2 will go to simon, and 1 for Jokeri. I can ordrer 10 boards if there is some interest in it from some european folks but I won't finish the assembly for 10 boards myself, so you'd have to solder the...

Proteus Plug and Play board for Miata/MX5 NB2 (72 pins)

Hi folks ! I'm here to present you my first creation (at least the first one I developped from scratch) which is a 72 pins PnP adapter for the Proteus board for 2001-2005 Mazda Miata (or MX5). It's equipped with the stock connector and can be equipped with two ampseal 23 pins connectors for extra fe...

Re: Rusefi driving of ecu relay

The main relay is either powered by the immobilizer/steering column or by the ECU depending on the OEM will. If it is powered by the immobilizer, you can power the ECU through the main relay output and it will be transparent both on the car OEM harness side and for the ECU. In that case you don't ha...

Re: microRusEfi pnp Miata MX5 NA

Yes perfect Miata time.
I'm tidying up the routing on the board (a few days), there is approx 12-14 days from ordering to delivery, add the dropshipping time to that and you have it. I will update design status as often as possible.

Re: E85 / Flex fuel logic

Sure, I've programmed in C++ before and done a bit of Object programming, but I'm not very used to git and just made it work this afternoon.
I've compiled the firmware for the first time too.
I could not find a "tree" of the code structure on which I could work.
Does someone have that ?

Thanks

I think the first step would be to implement a flexfuel sensor control. The GM type sensor is frequency related, so using th...

Hi ! I've built a small test rig with an arduino and a VNH board to play withy throttle body and all the variables I can set for the PID, and noticed that if you do not calibrate the ETB potentiometer range, the I term lead to very high current because it cannot reach the desired position.

Re: red 2003 VVT test mule Miata NB2 #27

What afr are you running at idle ? What is the CLT output ? This engine heats up pretty quickly, even when driving softly, I don't know why but I was surprised to see the coolant reach 70° in less than 3 minutes. Maybe it's just the fact that you're standing still and running at 2000rpm. Does the fa...

Do you still have the PCV valve connected ? The vacuum leak may come from it. Considering how loud is my idle screw on my mitata you should be able to easily spot the leak, or with the good old flammable liquid spray technique. What is the position of your throttle body without any power ? Is it ful...

If you are using the base VVT tune I think it is pretty rich at idle and low load and quite fine while running. At least it is what I observed

Re: 2004 Mazda MX5 1.8 VVT #50

Yup I'll leave the mechanical TB on the stock position, so it can eventually act like a failsafe.

For the TB I'm ready to try it out, I can try to tune the PID using an arduino before so that I can write a code quickly

Re: red 2003 VVT test mule Miata NB2 #27

If the catalytic converter is still in place it sounds pretty normal to me for an exhaust explosion. With the stock ECU on my full stainless exhaust (including cat removal) I sometimes get some pops like that on overrun (with a little bit of help tickling the gas pedal).

Re: red 2003 VVT test mule Miata NB2 #27

Yeah backfire on the exhaust, it seems to happen when the throttle opens and air is allowed in again. No big deal except if you had a catalytic convertor, now it's probably toasted 😂not as scartly as when I had my ignition reversed in a closed underground parking ;)

Sounds promising tho

On the 2003 Miata page low side driver is specified, but on the 2003 alt which is working for me it's stated that high side driver should be used. So as I see it it's just a question of switching the wiring to an unused low side driver. Will try that tomorrow eventually and give you some feedback on...
