well first off we got everything in place and the car starts up but it looks like the ecu is still reading off from a stock p28 instead of the chip. We chippied the ecu with a jun chip " vtec:4,400 Redline: 9,100 but then it doesnt redline at 9 one. it redlines like a stock p28 ecu which is 7,2. Whats wrong? does it matter if the resistor is hooked up backwards or something or it shouldnt matter?
