Formula413, I'm not familar with the motor in your car. Is it the 1.9 SPI? Anyhow, I had pinging for years under light load, turned out to be where the maf wires run into the air box. It is a vacuum area around the MAF on the ZX2, the plug was loose and letting unmetered air by the MAF so it was a bit lean, but under accel it would go away. Have you been to FEOA and asked around for some expert advice on that pinging?

To the orginal question, COZX2 ran his car between 210 and 230 constantly, regulating the temp with either the rad fan that he had on a switch or thru the heater. I'm sure he saw a significant improvement from running higher temps otherwise he wouldn't have done it.
