Going to hit up Eugene about this tomorrow for my tune as well. Definitely want all the bells & whistles.
Waiting on AT launch control until I upgrade the flex plate and torque converter though. |
Got some vids this weekend! I will be editing it and uploading to Youtube. Hopefully this evening.
So some more observations: 1st does not handle it well at all. The power gets shut off for 1-2 seconds like OEM. (ugh!) 2nd and up does well though! 2nd I can get it to reliably trigger at higher RPMs. My theory from just observing behavior is that different methods of control are hit based on percent difference from current wheel speed vs target wheel speed. At low differences, we are getting less invasive cuts. At higher speed differences, I think it falls back to the OEM style of TC. This is in line with the strategies I've read into on fully aftermarket TC solutions. The difference in Ecutek vs motorsports style solutions seems to come down to polling rate. |

EDIT:
Demo https://www.youtube.com/watch?v=NN0nMI9tMI0 Found Ecutek's documentation on 370Z traction control. Looks like they have a traction control table that retards ignition timing for given wheel slip percent and engine RPM, as well as a table that multiples throttle (meant to be 0-1.0 multiplier) as well. I'd love to be able to play around with this more myself because I think setting intervention at lower wheel slip angles would help a lot. A problem I'm seeing based of the example tables is there is not much resolution for single digit slip percentages. Without knowing what the table setup is, currently, I'd have a tough time tuning. Plus relying on Eugene or another tuner to make adjustments is a big barrier to testing and refining. Quote:

Learn to drive without the Traction Control. Who needs it on a NA 370z.

Tuner here in Tampa has been doing this for the last 5 years. Pretty much every tuner is so far behind the curve. Safire hawk has been running the tc through custom
Maps for the last 3 or 4 years. I can attest how great it is on the track compared to one, you can’t even tell when TC engages while On the track |

I’ll be running this TC map through ECU tek once I get back
To the track. Only downside is you will run through rear brake Pads |
Ha, yeah, I don't really keep my sig up to date.
Car's now in the process of being tuned by Eugene with the Rotrex kit, and I've been having fun exploring the setup just around town. Regardless of NA vs not, a well tuned TC setup is a great tool to have. I think gatekeeping traction control usage is part of why TC development is so ignored. 370Z stock traction control is woefully bad. We should celebrate that Ecutek's control can get it to something closer to a modern car's TC, and apparently with enough tuning effort, have it feel invisible. |

My suggestion would be to learn how to drive without it and then add in the future. It is a skill set that is invaluable to have. If you get into trouble, you will be able to save it instead of crashing the car. If you want to be hard headed and not listen, you can crash like other folks have done. You need your experience bucket to fill up before your luck bucket runs dry. That won't keep you from doing it but it will give you a fighting chance.

Have a listen to the last part of this video about traction control.
