In this case "as expected" would be in regard to the conventional ion sensor systems as used by SAAB etc. image.png Very similar to what we saw here with the SAAB system. https://github.com/rusefi/rusefi/wiki/Saab-Trionic-8-Combustion-Detection-Module-on-Mazda-Miata-running-rusEFI The irri...

Is this a case where getting engine info over CAN would be useful?

20V 1.8T Golf, p/n 4D0905351. One of these would be required in a wasted spark configuration, or two in sequential. Due to the nature of the twin spark design, I think two (or four) in sequential is best. Two vs four depends on answering Q1 from the OP. These are proven to work pretty well with the...

You are correct, it requires investigation of a new chip and possible modification to an existing platform which requires human time and input. This is near exactly what was proposed previously and was met with immediate hostility. A new platform was never suggested. Regardless I will leave that the...

Doesn't this just come under D?

Isn't any discussion of new hardware forbidden?

It is also worth noting that most cross ram engines with dual plenums up until about 2010 were actually running 2 ECUs. From the top of my head, the Ferrari stuff and BMW stuff was using 2x bosch controllers and the lambos used dual marelli ones. No need to balance your banks if you treat each one a...

So there's a couple of things here, your absolutely correct the spark discharge is a problem, the ion sense is essentially blind during the discharge which makes things difficult but not impossible. I don't want to give away too much detail at this stage but we have found a way to determine the tran...

For simple control we have been able to just PWM the pump via a GPIO map.

We managed to get some pretty good pattern coils from Maxpeeding rods, they seem to be working as a factory outlet for a lot of stuff now.

Think they were ~£85 for 8.

Wait.... It's running.

oh wait, I have just figured out what they are doing....

They are smart coils, the trigger line is also the ion feedback line.

I am not sure how we would interface with that based on the way RE ignition drivers work, it might make sense for you to take a look at the mazda or SAAB coils instead.

@ssmith - There does not seem to be any IGBTs in the MSS60 ECU which as you say would suggest smart coils. 3 wire is weird as you need 3 for the smart coil and a 4th for the ion signal. So yeah, with you on that, not sure what is going on there. Documentation for the S65 also seems to be junk compar...

Adding a couple more case fit pictures for the M60 case.

(And no, there isn't anything on that IP anymore, it was a note to myself a long time ago)

+12 volts

It is the incorrect component.

This may have caused even more damage.

Have you soldered a 0R resistor in place of the Diode D1 on the green board?

Something is really very badly wrong with your build as there is no way the voltage should be doing what you showing in the video.

I am sorry your kit may now be irrecoverable at this stage.

You may also have done permanent damage to you car by connecting it after we pointed out it is not ready.

Wait you connected 12v to this and fitted it into a car?

Have you done anything to rectify the soldering issues?!

Merged the three open topics into this one, please try to keep the discussion of this Frankenso to this topic. With the way the soldering looks it absolutely is not ready to plug into any kind of power. If you have powered it up already you may have ruined your board. Have you been able to look at ...

So the mazda coil has some electronics in it but getting them out did some damage, we think the mazda coil is self charging for the ~300v. We did get some info from a working CX-5 and it seemed to only be 5v on that signal line. Its very strange. It makes me think I should go destroy another one as ...

I believe there are pin compatible stm32 f429 vg that will allow you to use the official firmware.

It might be worth doing a chip swap.

Proteus is intended to work with the larger ram on the 429 VG chips due to the number of features on the proteus.

So this seems to be an issue of the IGBT drivers being on 100% due to the inverted setting. This will have surely cooked them and probably hot enough to melt that solder joint. It's possible they are now shorted to ground and causing issue elsewhere. First step is going to be removing those IGBTs an...

Have you looked at this thread?

https://rusefi.com/forum/viewtopic.php?f=4&t=1409

I also strongly recommend watching this video for some pointers on soldering the RE hardware.

I read through this thread, and am starting to process some of the academic papers regarding ion sense. So forgive me if I'm asking obvious questions. BMW S85 (and presumably S65, but it looks like they moved the electronics into the ECU) use dumb coils, and have electronics that apply the bias vol...

Just in case you were not aware, the parts manual for the E32 750 lists all the engine bay plugs and they are not too expensive even direct from a dealer. The Small square 2 and 3 pin plugs are just AMP junior power timer plugs (as is the ECU plug) some use micro power timer pins. You may find that ...

The standard solution used on the M20 engines will serve you well here. That is to replace the distributor rotor with a trigger wheel/tooth and trigger a Hall sensor using that. Common OEM hall sensor is the M54 cam sensor, it looks identical to an OEM BMW crank sensor and uses the same type of plug...

Fitting an M73 pedal would be a very good idea.

I will take a look into the sensors on the M70 throttles, there may be a better way around things

Just want to confirm a couple of facts.

The engine has the cam sensor in the distributor body yes?

Like the single cutout trigger wheel shown in this video?

Without wishing to curse it I have been using my Frankenso fitted E30 as my only car for the last 3 months while I have been working on the other one. 180 miles a week commuting so something like 2000+ miles on it this summer. I know I only half count by being an insider but it at least shows we hav...
