I thought it would be appropriate to post some up to date information about RLTC. There may be a lot of new buyers of RLTC out there who may not be aware of our previous extensive discussions on the subject. So I hope this will draw attention to some of the inherent but not insurmountable problems associated with the initial post installation use of RLTC.
Whilst at Bolney I helped Matt H to sort out his RL settings. I was curious to see what RL had put in the control unit as the stock TC settings file. The good news for anyone one buying RLTC for the Supra now is the file at least shows 6 cylinders to match the car. However that is where the good news ends. It looks like to get anything other than extremely basic functions from the system you are going to need access to a laptop and a tried and tested data file.
Matts internal file was set up as the manual shows, with every injector being cut on each of the injector pulses. The only cut table showing injection allowed was the Integration Threshold. This is not a safety issue, as traction control is provided, all be it very harsh, cutting of 5 out of 6 cylinders, virtually removing all power once the system detects slip. This set up is extremely basic and allows no progressive injector cutting
Even in this basic state the system is still far safer than stock MKIV TC as once the system detects that slip is reduced to acceptable limits, the throttle response returns instantly giving fully engine control when you need it. Without data in the other sections of the cut tables, as in Matts case, the system does provide basic slip control, but allows no control over the amount of slip and the launch facility is not functional.
Any members fitting RLTC, should be aware there are a number of members of this club who have fitted their own RL and a few of us who have experience of setting up the variable aspects of the system. Please feel free to message or e-mail me and I will see how we can help you.
