Re: 2004 Mazda MX5 1.8 VVT #50

Hi folks ! I now run my NB2 on straight E85. We have that chance in France to have E85 stations popping everywhere, last time it was 3 km (2 freedom length units) from home. Modified my injector rating to accomodate for lower energy density and the car runs really great. Timing was a bit too high be...

Hi everyone ! After a few weeks daily driving my NB2 on Proteus I'm now con fident enough to drive it 100% rusEFI. So I decided to swap my trigger plate in favor of a more precise one, coming from Mazda Protege. This wheel is 100% bolt on crankshaft pulley, just have to swap the old one out by remov...

Re: Another rusEFI K4M build, 1986 Renault 4 swap

Hi ! I'm not sure about any manifold yet as space is a bit restricted on a R4, I might need to use a R5 alpine exhaust or similar to make it fit under the hood. The R5 alpine engine is a cleon bloc too with 85mm spacing, only issue being the round exhaust ports.LAst option is cutom tubular header, e...

Re: Another rusEFI K4M build, 1986 Renault 4 swap

First meeting with my future chassis, which needs some work but is in a very nice shape considering its price tag. Got the engine out on a stand to disassemble it and see what was inside. I bought it in unknown condition and unknown mileage, and I was worries it was just a piece of crap. Opened the ...

Hi everyone ! Here to present my second RUSEFI project running a Renault K4M engine (https://en.wikipedia.org/wiki/Renault_K-Type_engine) using Proteus board. Proteus is way way overkill for this project but I have one spare so why not use it ? So the engine is currently experiencing maintenance as ...

Re: red 2003 VVT test mule Miata NB2 #27

That's only the EGR sensing solenoid, and not the EGR valve itself which I think is a separate stepper.
As for the solenoid why not grounding it altogether ?

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 ?

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...

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
