There are pics of how stig it used to look on page 40 (Post 400, clicky) so I'm happy with that. Still needs some tweaking though as I said...The chargecooler's not been rewrapped, so it needs to come off for that. I have bought some new brackets from Fusion Motorsport for the cinquicento radiator at the front, to replace my rotting mild steel ones that I made. I attacked the radiator a bit too vigorously with a jetwash at JTS last year, so that could do with replacing too. Being a FIAT part they cost next to nothing
So, I will drain the chargecooler system again, take the core off for heatwrapping, swap the front rad out and fit the new brackets all at the same time.Need to resurrect the list too :lol: I've got my new speedo converter to fit to resolve a PAS problem. The speedo sender in the gearbox transmits a signal to the speedo clock in the instrument cluster. This converts the signal to a standard PWM, which is then sent to the PAS ECU and the engine ECU. My existing speedo converter is a rather generic little box, which just multiplies the signal by 0.6 to convert KPH to MPH. This results in the speedo displaying MPH OK, and the ECU and PAS thinking that the car is travelling much slower than it is. This in turn defeats the ECU's 112MPH speed limiter, but it also reports a false speed to the PAS, so it never turns off. Past about 60mph this really feels like you're driving on ice!! The MR2's PAS system is supposed to vary assistance depending on speed like most modern assistance setups, but this goes totally out the window when it doesn't know the true speed of the vehicle.
The new converter works by taking the input signal and transmitting a different pulse to instrument cluster, and the ECUs. The instrument cluster's signal still gets multiplied by 0.6, resulting in an MPH speedo. The signal that's sent to the ECUs is the true speed, up to 100MPH. After that point, the converter carries on feeding 100MPH to the ECUs until the real speed drops below. Sorted :thumbup1:
It's a pretty simple affair, just screws to the back of the instrument cluster. I'll have to repair the wiring loom after I remove the existing converter but it's only 1 wire. Should be easy, right?
