Re: Skoda 120L + ITB
Just arrived :) rusefi1.jpg rusefi2.jpg Now I need some more time... All the passives are populated on Frankenso. But I have too much projects in parallel... Building rusEFI, doing a complete bodywork on my pickup. If it would not be enough, last week I bought my house which needs to be renovated......

Re: Skoda 120L + ITB
Thank your for your checking and suggestions! The PCB is already in production so no chance to change it But will be fine for the first tests.
BTW, you mentioned the LSU4.9
Any experience with the cheap ones from ebay? (~30USD)

Re: Skoda 120L + ITB
If you aligned the via's with the Frankenso board, you could simplify the connecting wires. Yes, that was my first thought also. But as I mentioned, this is a proof of concept board only. Maybe I had to switch to 4 layer that case. It's chepaer for the moment :-) (+ have more flexibility) Unfortuna...

Re: Skoda 120L + ITB
I do not want to put in too much effort. This board is just for proofing the concept. If works, I will integrate the whole stuff in one board.
If you are still interested, I can share the files.

Re: Skoda 120L + ITB
Just finished with the proto of my adapter board.
It includes the WBO circuitry with CJ125 and the throttle motor driver. (it was my first project in KiCad, just starting to figure out how it works...)

Re: Skoda 120L + ITB
I'm developing the electronic throttle body stuff on this guy: https://www.pololu.com/product/1212 A bit cheaper, and it's a chip that was designed to be an ETB controller. You're also guaranteed good support from rusEfi :) It's too late, I've already ordered some VNH5019 to develop my own module :...

Re: Skoda 120L + ITB
Just found, in the OEM ECU the idle motor is driven by TPIC0107

Re: Skoda 120L + ITB
As mentioned earlier, there's a position feedback pot for the idle motor. Here we have two options: - create a small circuit which receives PWM from rusEFI, drive the motor and handle the pot signal (no position feedback to rusEFI) - drive the motor directly from rusEFI's PWM, feed back the pot sign...

Re: Skoda 120L + ITB
The current is not known yet, but I guess it's not more than 4-5A. Will check it when I come closer to realization. Maybe an other output FET will be needed. I'm not afraid of HW side, but SW...

Re: Skoda 120L + ITB
Noone used similar config till know? I thought this kind of idle motor is more common... Than it will be a nice challenge

Re: Skoda 120L + ITB
One question is still remains open from the initial post.
Can I use my current idle motor (DC motor)? Just use as a simple idle solenoid and drive it with PWM? Will I need the feedback pot?

Re: Skoda 120L + ITB
I once created a PCB which would takes several MAP signals... Yes, I found it already when digging around the possibilities. 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...

Re: Skoda 120L + ITB
Yes, each TB has a dedicated vacuum port which are connected to a common MAP sensor. I get ~500-520mBar at idle.

Skoda 120L + ITB
Hello All, First of all a little introduction of me. I'm an electrical engineer, but dealing with cars in my free time as a hobby. I repair everything including engine, suspension, electronic, bodywork and also doing paint jobs as well. In parallel I'm building my old Skoda's. I have a 120L which is...
