Re: Peugeot 106 1.6 16V '97 TU5J4 NFX

Can you try with +5V instead of +12V ?

Re: My Build ,2005 Honda s type K24A3 Accord Help needed

Hello,

did you check the sparks with plugs outside the engine ? Are you sure about dwell ?

I don't know "ind coils". Is it smart coils ?

Re: Peugeot 106 1.6 16V '97 TU5J4 NFX

The VSS with 12v is probably an hall sensor, but they aren't all the same. Basically, an hall sensor has 3 wires, +12v (or 5v), Ground and signal. The signal is commonly a ground signal, so you have to put a pullup for testing (commonly a +5V with a 1 - 3K ohms resistor) You will have a square signa...

Re: "Proteus Little"

Nice ! I like new boards :D But, don't you prefer a more personal name ? It is confusing. And I don't understand the analog input, if you send 5V to the analog input from mcu, it's gonna burn ! 330ohms and 10K behind MCP6004 looks wrong to me. But I am maybe wrong too :P Same problem with 12V_DIVIDE...

Re: Discrete components VR decoder with zero firmware code

I forgot to share on the forum ! I tested the board on my MRE, with crank and cam input. My cam is more interesting, because of single tooth. (lot of noise, and more than 85ms between two signals at low RPM, it is a problem with MAX) I used "AUX J2 PB9" from the "general purpose PWM&q...

Re: 89 Nissan 1JZ-GTE non-VVTi with MicroRusEFI

I finally change the crank wheel by a VVTi one. It is now 36-2 instead of 12 without missing tooth. It is a 20$ crank wheel from china. If china sell it, there is probably a reason and a lot of trouble on the JZ without vvti. VR trigger.jpg It allows me to use the MRE without additional boards, but....

Re: Forester SF SOHC

Did you try to change the polarity of your VR when you set "use only rising edge" on true ? Without a scope, it is complicated to know if your VR is well wired. With a MAX (like proteus) your signal has to go up then down. (rising edge then falling edge, to be precise) But with some OEM or...

The problem is with 2JZ_1_12, the pattern for 1JZ and 2JZ without vvti. It is 12 teeth crank and 1 tooth cam. The only thread that I found with this pattern is a russian post and translation isn't fine. Here is a video of a coldstart, without tune, without idle and without throttle. https://www.yout...

Re: Discrete components VR decoder with zero firmware code

Wow fast response ! There is no voltage input in the DAC without resistors, it is only when there is resistors, it is why there is a 100K / 310K divider before STM, it sends 0-2.5v. The "threshold" in the schematics is a room to solder resistor when STM pins not plugged. It allows to have ...

There is no simulation of the complete circuit, it will be done for real. (in approx 20days :roll: ) In theory, there is no delay/lag for an engine.
