Sure, if I want to set some conditions ;-)
The question is about HOW TO DO THIS WITH A BUTTON

Plus, your method don't switch strategies, but tables ;-)

The question is about strategies

Cheers,

I think I found a way using Curve blending.

Using a button with two states in "Generic sensors" => 0v = 0 / 5V = 100 (linear) and then using Blending curve 1 with only these 2 steps should switch from VE1 to VE2

Hello,

Is it possible to change the primary strategy using a button ?

A customer would like to switch between tps/speed to MAF (with one table per strategy) using a switch.

Hello,

I never tried. I think a dev can/should answer. At the moment, due to chips shortage, I redo the module with another microprocessor. Si I haven't a module left to try

Maybe this week-end I can get a hand on one at a customer location. If I do, I'll test and report.

Best regards,
Manu

Thank you, I had the same thought this afternoon.

But in this case would the AFRtarget will be 14.7 rather than 14 ?

Thank you.

Hello, I'm not sure about the problem. It may be related to firmware but I can see it with MLV HD, so I use this topic. MS2 with 3.4.4 firmware here. This log is issue from a moment when one use TS Autotune at the same time than laptop logging. You can see that AFRtarget1 is stuck à 14.0 when AFRtar...

I bet you use 29bit protocol. This is very MS specific. Some customers use TransControl firmware with other ECUs and some asked me for this feature => 11bit broadcast. This way, they can use the data for logging, display, safety, ecus features, etc... Nice that you would consider this feature. Do yo...

Hello,

Is it possible to broadcast gearbox temperature, engaged speed,vss over CAN ?

Thank you,
Manu

In such case, I use to use a 1:1 dual transformer to split the VR signal in 2 equals signals without perturbations.

Hello,

The stock 3.57 trigger system can't handle the Renix trigger wheel well. You have to use JBperf DualVR module available here :

Hello, Yes this sensor need internal mods of the Microsquirt v3 to operate well. This mod is useful for all EURO engines because they often use, at least, 60-2 trigger wheels where US often use 36-1. I guess that the Microsquirt was designed with 36-1 in mind. So we apply an internal mod on all Micr...

Hello,

Yes, the 60-2 renault trigger wheel operate well with ms2/ms3/microsquirt code and hardware. The long teeth is no longer a problem since years.

@Matt => one don't use the Renix wheel decoder for this setup but the standard trigger wheel, like 36-1.

Best regards,
Manu

They are OK

No

What king of spark plug do you have ? Resistive ones ? I guess not.

Hello,

You should first try without the cam sensor in batch fire.

The signal from your logs are good. But the primary signal should be inverted (going low). Try both, one should start the engine and get a steady timing (timing light to control), the other will give inconsistent timing.

Hello,

This dash will not operate with an megasquirt product.
This dash is intended for OBD2 standard. Megasquirt don’t implement/use OBD2 frames.

Manu

Hello,

When one use another language than EN, the menu did not appear.

Thank you,
Manu

Microsquirt is very reliable. I guess you have ground problems or maybe non resistive spark ?

A little delay AFTER the engine start will be a bonus IMO.
But anyway, this was some examples of benefit of a such feature (delay in programmable output)

Manu
