Thread: TunerCode Feature Suggestions and Feedback

Lets start a discussing features that we would like to see in TunerCode. To keep it easy to read and understand, please follow the posting guideline. I will try to keep the first post up to date with the most desired features.

Feature Request:
Feature: Short Name of the feature
Description: Description of what the feature is or how it works.
How should it be implemented: What can the ECU do to address it (i.e. if ECU detects knock, it will pull back timing to avoid knock).

Feature: Traction Control
Description: Cutting back throttle when wheel spin/hop is detected.
How should it be implemented: Cutting back the timing might be a way to reduce the throttle delivered to the wheels. The hard part here is detecting actual loss of traction though.

^^ do our ECU's monitor wheel hop? or would it piggy back on other sensors like RPM & stuff?

Not that I know off, I'm pressure sure it would have to be piggy backed. Unfortunately that's a hard one to figure out. And the ECU might think it's loosing traction when in reality your are just going fast.

Feature: Power by Gear (Boost by Gear)
Description: Reduce the amount of power the engine would make depending on on the gear you are in to help aid loss of traction.
How should it be implemented: Limiting TP, similar to Overboosting, would be one way of doing it, but unfortunately that would mean you hit an early fuel/timing cut. Thus it would have to be a way to allow the car to still make power, but not as much in a certain gear. Timing reduction might be a way to solve this.

these features would require a wheel speed sensors. for traction control it would compare front wheel speed to rear wheel speed to determin if they are spinning, and for boost by gear it would need a signal from the speedo output to the ECM

The ECM knows the speed limit, I have a 92 ecu and knows and outputs it to my P11 dash no problem .

i guess i was just thinking of my E01 not an actual ECM, my bad

Thoughts on the above suggestions:

1. Traction control. Relocating the wheel speed sensor to the rear would fix the issue of the ECU not knowing the actual 'road speed'. If the RPM was to rise above the given mathematical calculation for the speed VS RPM then it could do whatever to limit power. However, its very simplistic and something like the Racelogic system would be far better if you were really serious about it.

2. Speed sensor feed the dash, which in turn feeds the ECU. Unfortunately, the ECU sensor update rate for speed is very low. i don't know if the sample rate is/can be increased through the use of Tunercode or how Dave has written it, but it would need to be significatly increased (perhaps in conjunction with a more accurate/high resolution sensor?) to make it really useful.

3. All of the above will depend on tyre size, specific gear ratios being known and within a certain % of allowed slip, again an aftermarket system is going to be king here.

Boost by gear - if the ECU can output a PWM signal to a solenoid to control boost, then it could do approximate calculations based on speed and RPM to determine the gear and then boost could certainly be shaped, but again, speed being a slowly updated sensor might come into being an issue down the 1/4 mile for example.

Just some things to think about. Please feel free to correct me on any of those thoughts.

V did you talk to Dave before posting this? He already has an extensive list and I am pretty sure these are on there.

As for TC you guys aren't thinking very deep. When Dave and I talked about it we discussed doing a slew rate table for acceleration so that you could work with just inputs already there... Pretty simple.
