Hi at @Simon, got everything wired up and running, had an issue with the fpr not releasing fuel at idle and cavitating but should have that sorted with a new fpr. One problem is the coolant sensor, from cold I either a) get a reading of 36c that drops to about 20 or b) get a reading of 96 that rises to about 105. I've checked the earth's and they're all good. It's there a way to calibrate it or do I need a specific type. From memory this was working with a very early g1 (97ish) it's not the stock mazda item..
