[QUOTE="P49Y-CY, post: 16299729, member: 10216"] yes i did it once in the driveway jon (only idling) with the parameters you mentioned in post #61. but i'm thinking i need to try it again because all of the numbers seemed waaayy off. none of it made any sense to me. but if i can somehow post it up here i will for example, these were the average numbers over about a 10 minute period: - battery volts: 0.429 - coolant head temp: -18667.4 (negative value!) - coolant temp: -3.405 (negative) - maf ad counts: 509.353 - pressure drop fuel injector: 114.436 - rpm: 3538.939 (i didn't rev the car over 2200 the whole time?) - returnless fuel pump duty cycle: 0.849 - short term fuel trim bank 1: 0.487 - short term fuel trim bank 2: 0.343 [/QUOTE]
