[Closed loop coolant temperature ctrl w/ map controlled thermostat]

8 hours ago, NickRP said:

We will be using map controlled thermostat and would like to have a closed loop coolant temperature regulation, based on a setpoint formed by certain process variables (like environmental temperature, thermal load etc).
Can Thunder do that? Electrically it can do pwm on the thermostat heater (it's 1 Amp max) without problems, but is there an available control loop to do the actual regulation?

 

On my setup I use a 3d table to PWM an engine water pump. After a lot of testing I found using the temp output from the radiator and ECT the best way to control the pump. Takes into account out side temp and vechile speed. Would recommend you try that way to control the thermostat. Ive also connected a 2nd Digital output to the same soild state relay as an override. So if I'm at a set TPS or boost range the pump goes to 100%. After a bit of testing during different conditions I can keep the ECT within 2deg in all situations. 

[Engine protection question]

All this is already possible. I use oil pressure, differential fuel pressure and lambda as extra limits on top of the basic features. And yes there is a delay available.

[2JZ anti lag & launch switch]

Chassis ground.

[Hondata Strain Gauge]

Features say, Analog (voltage) output proportional to gear level force. So you need to use a Analog input not a digital input.

[Odd question - limiting torque through tuning]

On my ride I reduce timming at peak torque and boost in the lower gears. 

[Trigger setup]

If you are not using a wide band sensor your just wasting your time. Plenty of cheap controllers out there.

The sensor pic you posted is not the correct sensor for tuning fuel maps.

[Thunder Injector Wiring Dual Fuel Systems.]

What's wrong with using multi fuel modeled mode. Are you using 8 or 16 injectors?

[-123-]

Yes, I use the display link with the G4+ Thunder

[G4+ extreme with old displaylink dash]

Have you configured the CAN as per the previous G4.

[Lean Spike Between Gears]

That lean spike is over a 200ms time frame. Just saying....... 

[Hella SSR Relay fuel pump control issue.]

How close are you guys putting the flyback diode to the load? Does it matter how close it is to the load. 

[Closed loop lambda]

Your Calibration table is out. Use Cal table 7 so you can set the voltage axis

[Closed loop lambda]

Looks like the wide band signal freezes. What type of wide band are you using?

[Closed loop lambda]

Never mind didn't see the other link

[Closed loop lambda help]

Lambda 1 and avg trend are the same that i can see. lambda target is not the same 

[Closed loop lambda help]

Can u post a log file.

[What is wrong with my tune?]

Surely any link dealer should be capable of tuning a link using the current software. Another reason why tunes get locked IMO.

[What is wrong with my tune?]

Another look show it's reducing boost target in higher gears but gear detection is not set up correctly. Your vechile speed is showing when in 0 gear. 

[What is wrong with my tune?]

Also looks like base fuel pressure is only 2.5 bar. You have a fuel pressure sensor input but not using it in the modelled equation.

Injector dead time curve has steps in it. 

 

[Wideband display problems]

More info would be nice. What wideband have you got? If it is a link are there any faults showing in the runtime screen.

[Modelled fuel critical settings]

Injector data is the most important. 

[New monsoon won’t start]

I take it you have put in the unlock code? 

A trigger scope on cranking will help tech support once the work day starts

[Thunder lambda sensors]

Could you post some pics of the engine bay setup.

How is the MSD grounded?

Also could you post a trigger scope at idle.

 

[Thunder lambda sensors]

If you unbolt the tps sensor from the throttle body when running does the log trend change?
